Hog Slat: BlogBloghttps://hogslat.com/Tue, 19 Mar 2024 03:41:45 GMTurn:store:1:blog:post:292https://hogslat.com/test-day-at-bess-labsTest day at BESS Labs<p>If you are involved in buying or selling agricultural fans, chances are you are familiar with BESS Labs. For 34 years, BESS Labs, also known as Bioenvironmental and Structural Systems Laboratory, has been the go-to source of unbiased fan data for both producers and manufacturers. I recently got to join one of Hog Slat's engineering teams for a testing session at the University of Illinois campus.</p> <p>&nbsp;</p> <p>On the day of our scheduled session, we arrived at BESS Labs on a bright but freezing cold day. As the engineers prepared the first test fan, I asked lab manager Steve Ford about the lab's origins.</p> <p>&nbsp;</p> <p>Steve said, "In the late 1980s, a group of Wisconsin electric coops wanted to develop a rebate program to encourage the use of energy-efficient fans. However, they discovered that the cfm/watts data required to create the rebate program was unavailable. Subsequently, the coop personnel contacted the university's engineering department to perform the necessary tests. For the initial testing in 1990, the coop purchased 40 fans from multiple vendors and shipped them to Champaign."</p> <p>&nbsp;</p> <p>Steve explained that BESS Labs has tested as many as 900 fans in a year, but on average, they test between 500 and 600 fans annually. Fans come from manufacturers worldwide, including fans not designated for sale in the US. The testing done by BESS Labs provides foreign manufacturers with confirmed data accepted throughout the world.</p> <p>&nbsp;</p> <p>So, what is a wind tunnel?<br /><br /></p> <table border="1" style="border-collapse: collapse; width: 99.9995%;"> <tbody> <tr> <td style="width: 97.9286%;"><img src="/images/uploaded/2024 Blog/BESS Labs/Wind-Tunnel_900x450.jpg" width="900" height="450" alt="" /></td> </tr> <tr> <td style="width: 97.9286%; text-align: center;">Image of wind tunnel</td> </tr> </tbody> </table> <p>&nbsp;</p> <p>&nbsp;</p> <p>The BESS Lab unit is a 9' x 9' x 26' long wooden chamber. To begin the test, the team fastened the test fan at one end of the chamber and warmed up the motor for 15 minutes.</p> <p>&nbsp;</p> <table border="1" style="border-collapse: collapse; width: 99.9995%;"> <tbody> <tr> <td style="width: 97.9286%;"><img src="/images/uploaded/2024 Blog/BESS Labs/Blower-Fan_900x450.jpg" width="900" height="450" alt="" /></td> </tr> <tr> <td style="width: 97.9286%; text-align: center;">50 hp, variable speed blower fan pressurizes the test chamber</td> </tr> </tbody> </table> <p></p> <p>&nbsp;Then, a 50 HP variable speed blower fan at the other end pushed air through a honeycombed mesh wall called an air settling screen to even out the flow.</p> <p>&nbsp;</p> <table border="1" style="border-collapse: collapse; width: 99.9995%;"> <tbody> <tr> <td style="width: 97.9286%;"><img src="/images/uploaded/2024 Blog/BESS Labs/Nozzles_900x450.jpg" width="900" height="450" alt="" /></td> </tr> <tr> <td style="width: 97.9286%; text-align: center;">Nozzles in the wall provide a known cross-sectional area</td> </tr> </tbody> </table> <p>&nbsp;</p> <p></p> <p>Next, the air passed through a wall of precisely calibrated nozzles with a specific cross-sectional area. Sensors on each side of the nozzle wall recorded the pressure drop as air passed through the nozzles to determine the amount of cfm being moved. The air then passed through a second air settling wall before reaching the test fan. Steve varied the speed of the blower fan to test airflow at typical negative pressures such as .05, .10, .15, etc. Additional sensors also recorded power consumption at each stage.</p> <p>&nbsp;</p> <p>&nbsp;</p> <p>Our session included verifying air delivery and efficiency for 36, 54, and 57-inch fans with different prop, motor, and pulley combinations. The engineers were particularly interested in the results of the OMNI motor drive powering a new fan series scheduled for release later this year. The test confirmed the expected efficiency and precise speed regulation, along with considerable improvements in motor protection.</p> <p>&nbsp;</p> <p>The couple of days spent at BESS Labs proved to be an insightful experience in the fan testing process. Undoubtedly, their unbiased platform over the past decades has driven the efficiency improvements seen in the fans used by the livestock and poultry industries.</p>urn:store:1:blog:post:291https://hogslat.com/diy-feed-auger-repairsDIY feed auger repairs<p>Save money by performing basic auger repairs yourself.

Reducing air stratification in livestock and poultry buildings maintains a comfortable environment for animals while also helping to lower heating costs. Here are some strategies to address and reduce air stratification in production buildings:</p> <p>&nbsp;</p> <p><strong>1) Insulate building shell.&nbsp;</strong>In colder weather, poorly insulated walls may become colder than the air inside. As a result, the air in contact with these cold walls cools down. This cooler air tends to be denser and may sink to the lower parts of the room. Improve the R-Factor of curtain-sided buildings with removable <a href="https://www.hogslat.com/tempshield-barn-curtain-insulation">Tempshield</a> insulation placed behind the curtains.&nbsp;</p> <p>&nbsp;</p> <table border="1" style="border-collapse: collapse; width: 100.057%;"> <tbody> <tr> <td style="width: 98.142%; text-align: center;"><img src="/images/uploaded/2024 Blog/Stratification/Fan-covers_900x450.jpg" width="900" height="450" alt="" /></td> </tr> <tr> <td style="width: 98.142%; text-align: center;">Fan covers prevent cold air from leaking through summer fans</td> </tr> </tbody> </table> <p></p> <p><strong>2) Seal up any air leaks.&nbsp;</strong>Cold outside air entering the building falls directly to the floor, creating a colder zone at animal level. Even the most minor cracks add up. For instance, a 1/4" crack around an exterior walk door equals 58 square inches, equivalent to having a 7.5" x 7.5" opening in the wall.&nbsp;&nbsp;Large summer fans have the potential for unwanted air leaks during the winter. Seal leaky shutters and install <a href="https://www.hogslat.com/poly-exhaust-fan-covers">fan covers</a> to prevent unwanted air from entering the building. For a more detailed look at this process, go to <a href="https://www.hogslat.com/fan-shutter-heat-loss">Fan Shutter Heat Loss</a>.&nbsp;&nbsp;</p> <p>&nbsp;</p> <p><strong>3) Air Inlets.&nbsp;</strong>After sealing the building, check the incoming air speed from the ventilation inlets. Maintaining an air velocity of between 800 to 1,000 feet per minute allows the cold incoming air to mix with the warmer room air before falling to the floor. Use a handheld <a href="https://www.hogslat.com/kestrel-wind-temp-humidity-meters">wind meter</a> to measure air velocity. We discuss setting and maintaining air inlets in our blog <a href="https://www.hogslat.com/managing-transition-ventilation">Managing Transition Ventilation.</a></p> <p>&nbsp;</p> <table border="1" style="border-collapse: collapse; width: 100.057%;"> <tbody> <tr> <td style="width: 98.142%;"><img src="/images/uploaded/2024 Blog/Stratification/Wind meter_900x450.jpg" width="900" height="450" alt="" /></td> </tr> <tr> <td style="width: 98.142%; text-align: center;">Use a wind meter to measure incoming air velocity</td> </tr> </tbody> </table> <p></p> <p><strong>4) Stir fans.&nbsp;</strong>Stir fans do an effective job of breaking up stratified air inside a building. Operating the stir fans at a minimum speed creates a gentle circulation pattern to mix the air layers. Forcing the warmer air to the floor reduces heating costs and produces a drier floor. Tilt the fans towards the ceiling and monitor airflow at floor level, being aware that movement more significant than 50 fpm can feel like a draft to the animals. Shop <a href="https://www.hogslat.com/windstorm-stir-fans">stir</a> and <a href="https://www.hogslat.com/windstorm-circulation-fans">circulation</a> fans.</p> <p>&nbsp;</p> <p><strong>5) Radiant heating systems.</strong>&nbsp;Forced air heaters contribute to heat stratification by layering heat from the ceiling down. By contrast, gas brooders, heat lamps, tube heaters, and heat mats all put their heat at floor level. By only heating the necessary areas, zone heating systems can be more energy-efficient than uniformly heating the entire space. This targeted approach reduces energy consumption and associated costs.</p> <p>&nbsp;</p> <p>By combining these strategies, producers can create a more comfortable and energy-efficient environment for their animals while reducing heating costs associated with air stratification. It's essential to tailor these solutions to each livestock facility's specific needs and characteristics.</p> <p>&nbsp;</p>urn:store:1:blog:post:289https://hogslat.com/downtime-baiting-strategies-for-rodent-controlDowntime baiting strategies for rodent control.<p>After the animals leave the farm, close the building up tight and simulate the same environment as when the birds or pigs were present. This practice keeps the rodents in the barn looking for food instead of migrating to another building. Remove all remaining feed, leaving the rodenticide as the only food source. Let the houses set undisturbed for two or three days, if possible, with seven days being ideal.&nbsp;</p> <p>&nbsp;</p> <p>Place feed trays along the walls 8-12 feet apart for mice and 15-30 feet apart for rats.&nbsp;<a href="https://www.hogslat.com/paper-feeder-tray-poultry-chicken-chicks">Paper trays</a>&nbsp;are the ideal holder for this application when domestic animals are not present in the buildings. They are inexpensive and easy to dispose of after finishing the baiting period.&nbsp;&nbsp;</p> <p>&nbsp;</p> <p><a href="https://www.hogslat.com/liphatech-cannon-soft-bait-4-lb-bag">Cannon</a> soft baits are the product of choice for downtimes of less than 14 days. If the downtime is longer than 14 days, start with <a href="https://www.hogslat.com/fast-draw-soft-bait">FastDraw&nbsp;</a>soft baits for seven to 10 days, then rotate to Cannon for the remainder of the cleanout. Monitor the consumption of the baits, replacing them with fresh ones as necessary, ensuring they are not contaminated or wet. Remove all baits and floor trays before restocking the buildings.&nbsp;</p> <table border="1" style="border-collapse: collapse; width: 99.9396%;"> <tbody> <tr> <td style="width: 98.1151%;"><img src="/images/uploaded/2023 Blog/Downtime rodent control/Rat-Baits-Combo_900x450.jpg" width="900" height="450" alt="" /></td> </tr> <tr> <td style="width: 98.1151%;"> <div style="text-align: center;">Soft baits can be zip-tied overhead or fixed on wire to bait under slats</div> </td> </tr> </tbody> </table> <p>&nbsp;</p> <p>Remember to concentrate on other areas of the houses, including attics, manure pits, office areas, and other structures close to the production buildings, such as well houses or generator sheds. Soft baits impaled on a wire or nail can be attached to rafters overhead and fastened to supports below concrete or plastic slats. Also, make sure the bait stations around the houses have fresh bait and are clear of grass and debris where rodents can hide.&nbsp;</p> <p>&nbsp;</p> <table border="1" style="border-collapse: collapse; width: 100.057%;"> <tbody> <tr> <td style="width: 98.142%;"><strong><img src="/images/uploaded/2023 Blog/Downtime rodent control/Cool-Cell-Rodent-damage_900x450.jpg" width="900" height="450" alt="" /></strong></td> </tr> <tr> <td style="width: 98.142%; text-align: center;">Rodent damage to cool cell pads.</td> </tr> </tbody> </table> <p></p> <p>&nbsp;</p> <p>One final note in regard to buildings equipped with cool cell systems. When cool cells are not operating in winter, rodents will use the troughs to nest in, creating problems during spring startup. Rodents also like to burrow into the cool cell pads; mice and rats alike will use this material and area to build nests since the water is not running. Renegade Mini Blocks are ideal for these high moisture environments.&nbsp;</p> <p>&nbsp;</p>urn:store:1:blog:post:288https://hogslat.com/upgrading-your-auger-fill-systemUpgrading your auger fill system<p>In a previous article, <a href="https://www.hogslat.com/short-cycling-reduces-motor-life">Short Cycling Reduces Motor Life</a>; we covered the expected reduction of motor life when the off time between starts falls below 30 seconds. Heat builds up in the motor, damaging the windings and bearings.</p> <p>&nbsp;</p> <p>As the industry replaced mechanical paddle-type switches with electronic proximity switches, motor short-cycling became more of an issue. The physical size of a paddle switch means the feed level will rise and fall over a longer distance before activating the switch. The size of this differential may be over two inches or more. The smaller size of a proxy switch means it may only have a feed level differential of only a 1/2 inch — the larger the differential, the longer the potential off time. Although a paddle switch can have a built-in longer delay time, it is not controllable and will vary depending on feed consistency.</p> <p>&nbsp;</p> <table border="1" style="border-collapse: collapse; width: 100.07%;"> <tbody> <tr> <td style="width: 97.6152%;"><img src="/images/uploaded/2023 Blog/Auger upgrade/Proxy vs Paddle_900x450.jpg" width="900" height="450" alt="" /></td> </tr> <tr> <td style="width: 97.6152%; text-align: center;">Paddle switches have a larger feed level differential than proxy switches</td> </tr> </tbody> </table> <p></p> <p>&nbsp;</p> <p>The solution to controlling motor off time is adding a delay relay kit. Which kit to install depends on whether the auger control contains a built-in relay. GrowerSELECT, AP®, and Cumberland® equipment include a relay, so the GrowerSELECT<a href="https://www.hogslat.com/grower-select-delay-relay-wo-internal-relay-hs617">&nbsp;HS617</a>&nbsp;relay kit without an internal relay is the right choice. Chore-Time® systems do not contain a relay, so they require a GrowerSELECT<a href="https://www.hogslat.com/grower-select-delay-relay-kit-hs598">&nbsp;HS598</a>, which includes an internal relay.

Even if freezing is not a problem in your area, water allowed to remain in the system can harbor dirt, bacteria, and algae, clogging the system on start-up next spring.&nbsp;</p> <p>&nbsp;</p> <p>Begin by shutting off the water supply to the system inside the barn. Next, open the drain on the lower trough and start the pump to remove any water from the sump tank and the system piping. Open the ball valve at the far end of the distribution line and on the filter to finish draining the system.</p> <p>&nbsp;</p> <p>Loosen the union connections for the jet or sump pump and remove and store them in a warm area. Stuff some steel wool into the pipe openings to prevent insects, rodents, and lizards from entering the PVC distribution system.</p> <p>&nbsp;</p> <p>Finally, place some extra bait stations in front of the cool cell runs and keep them baited to prevent rodents from building nests in the pads over the winter.</p> <p>&nbsp;</p> <table width="538"> <tbody> <tr> <td><img src="/images/uploaded/2023 Blog/Auto Greaser/Auto-Greaser_900x450.jpg" alt="" width="900" height="450" /></td> </tr> <tr> <td style="text-align: center;">The Auto Greaser injects lubrication into the bearings as needed.</td> </tr> </tbody> </table> <p>&nbsp;</p> <p>And what is the interesting new product? The Hog Slat Auto Greaser.</p> <p>&nbsp;</p> <p>This product shows some promise for increasing the life of fan bearings. Read this excerpt from a bearing manufacturer's website.&nbsp;</p> <p><strong>&nbsp;</strong></p> <p><em><strong>When operating in excessively moist, dusty, or hot environments, it is recommended that grease be supplied at regular intervals. If appropriately maintained, the rated life of the bearing can be extended.</strong></em></p> <p>&nbsp;</p> <p>A moist, dusty, or hot environment sounds exactly like the inside of an exhaust fan. Let's be honest: very few people will take the time to grease bearings multiple times during the season. When prepping fans for summer, grease gets pumped into the bearings until it oozes out the sides. Not only does this damage the seals, but housing full of grease can generate excess heat through fluid friction. The Auto Greaser ends the cycle of over and under lubrication.&nbsp;</p> <p>&nbsp;</p> <p>Install the Auto Greaser in place of the bearing zerk. Pump the body half full of grease, and the spring-loaded plunger injects grease into the bearings as needed. How long will the 1-ounce grease reservoir last?

Here’s a basic preseason tune-up checklist.  <o:p></o:p></span></p> <p><span> </span></p> <p><span>1) Fan belts <o:p></o:p></span></p> <p><span>Replace them every year. It's common to see fan delivery diminished by as much as 20% because of worn belts. Fan belts don't stretch; they wear from constant contact against the pulleys. They ride lower in the pulley grooves as they get thinner, causing the fan blades to rotate slower.  <o:p></o:p></span></p> <p><span> </span></p> <table width="500" height="42"> <tbody> <tr> <td><img src="/images/uploaded/2023 Blog/Preseason fan/LinkBelt_900x450.jpg" alt="" width="900" height="450" /></td> </tr> <tr> <td style="text-align: center;">Check for cracks along the neck portion of the individual links and note direction arrows when replacing.</td> </tr> </tbody> </table> <p><span><br />If your fans use a link-style belt, check for cracks on the neck portion of the individual links. The neck is the part of the link subject to the highest amount of stress as it rotates around the pulleys. Replace the entire belt, not just the damaged link. Since every link is subject to the same amount of flexing, the rest will probably continue to fail in short order. Also note the direction arrows on the belt, making sure the belt is replaced on the pulleys with the arrows pointing counterclockwise. For detailed instructions on installing a link-style belt, click </span><a href="https://www.hogslat.com/power-twist-v-belt-for-fans-type-b" target="_blank"><span>LINK BELT</span></a><span> and watch the instructional videos at the bottom of the page. </span></p> <p><span> </span></p> <p><span>2) Check the pulleys<o:p></o:p></span></p> <p><span>While you have the belts off, visually examine the pulley grooves for wear. The grooves should have a sharp V shape. Replace pulleys with rounded grooves. The </span><a href="https://www.hogslat.com/hog-slat-laser-fan-pulley-alignment-kit">Laser Fan Pulley Alignment Kit</a><span> is an excellent tool for aligning new pulleys with the existing drive assembly. Easy to use, place the laser pointer in the pulley groove and adjust the target piece in the new pulley until it lines up. The target piece also functions as a pulley groove gauge to check existing pulleys for wear.<o:p></o:p></span></p> <p><span> <br /></span></p> <table width="501" height="42"> <tbody> <tr> <td><img src="/images/uploaded/2023 Blog/Preseason fan/Laser-Align_950x450.jpg" alt="" width="950" height="450" /></td> </tr> <tr> <td style="text-align: center;">Laser Alignment Kit aids in aligning new pulleys.</td> </tr> </tbody> </table> <p></p> <p><span>3) Keep the pulley size the same.<o:p></o:p></span></p> <p><span>Some growers try to boost fan output by switching to a larger pulley that increases the propeller speed. At best, this is a short-term solution. Operating a fan at a higher speed for an extended period increases the amp draw on the motor, causing it to overheat. Overheating is the leading cause of motor failure. </span><a href="https://www.hogslat.com/is-changing-fan-pulleys-a-cost-effective-shortcut-to-boost-fan-output">Click</a><span> to read more about the hazards of boosting fan performance by increasing pulley size.  <o:p></o:p></span></p> <p><span> <br /></span></p> <table width="452" height="42"> <tbody> <tr> <td><img src="/images/uploaded/2023 Blog/Preseason fan/Auto-tensioner_900x450.jpg" alt="" width="900" height="450" /></td> </tr> <tr> <td style="text-align: center;">The indicator bar on the auto tensioner registers correct belt tension.</td> </tr> </tbody> </table> <p></p> <p><span>4) Check the auto tensioner<o:p></o:p></span></p> <p><span>If your fans have an auto tensioner, flex it several times to make the internal spring has not seized. You should also check for proper tension by checking the position of the indicator marks on the body. The indicator bar should register between the first and second marks on the tensioner body with the belt on. To increase the amount of tension, rotate the body nut counterclockwise.  <o:p></o:p></span></p> <p><span> </span></p> <p><span>5) Clean the shutters<o:p></o:p></span></p> <p><span>Dirty fan shutters can reduce fan output by 8%. Use a broom or brush to clean instead of a power washer. Leave the broom where it is handy to keep the shutters clean throughout the season. Replace any bent or damaged vanes or rods that might prevent the vanes from closing. <o:p></o:p></span></p> <p><span> </span></p> <p><span>6) Fan cones<o:p></o:p></span></p> <p><span>1) Cones add 10% to fan performance; missing parts nullify their effectiveness. Replace any missing parts damaged by snow, wind, or ice.<o:p></o:p></span></p> <p><span> </span></p> <p><span>Ventilation fans are no different than any other piece of equipment on the farm...they perform better with annual maintenance.

PolyStorm fans feature roto-molded High-Density Polyethylene (HDPE) housings. HPDE is a durable plastic with great low-temperature impact strength and excellent chemical resistance. HPDE is also less expensive than similar corrosion materials such as fiberglass resulting in <strong>significant cost savings per fan.</strong> <o:p></o:p></span></p> <p><span> </span></p> <table width="441" height="42"> <tbody> <tr> <td><img src="/images/uploaded/2023 Blog/PolyStorm/PS-Interior_900x450.jpg" alt="" /></td> </tr> <tr> <td>PolyStorm fans feature PVC shutters, stainless-steel motor mounts, and GrowerSELECT motors</td> </tr> </tbody> </table> <p> </p> <p><span>Along with the HPDE housing, PolyStorm construction consists of stainless-steel supports and hardware, coated fan guards, PVC shutters, and GrowerSELECT motors with a 2-year warranty.  <o:p></o:p></span></p> <p><span> </span></p> <p><span>The only real shortcoming of HPDE is its lack of rigidity, which limits its use to fans 30 inches or less. PolyStorm fans are available in 14, 18, and 24-inch models. <o:p></o:p></span></p> <p><span> </span></p> <p><span>While PolyStorm fans are an excellent choice for new ventilation systems, their biggest value may be for remodeling and retrofit projects. When restarting facilities that have sat idle, considerable labor is required to remove stuck props, replace motors, and repair damaged shutters on the existing fans. It may be more cost-effective to replace the entire fan with a lower-cost PolyStorm model with a 2-year warranty.<strong> </strong>For example, replacing the motor and shutter on an existing 24-inch fan would cost almost as much as a new 24-inch PolyStorm.<strong> </strong>Also, the PolyStorm housings have a smaller profile making them more likely to fit in smaller rough openings used for older fans. <o:p></o:p></span></p> <p><span> </span></p> <p><span>Unlike most fans with poly housings meant for light commercial use, the PolyStorm fans are robust products designed for animal production facilities. </span><a href="https://www.hogslat.com/polystorm-fans">Click</a><span> to learn more.  <o:p></o:p></span></p>urn:store:1:blog:post:278https://hogslat.com/benefits-of-using-tube-heaters-for-weaned-pigsBenefits of using tube heaters for weaned pigs<p><span>Benefits include improved heating zone and less maintenance.<o:p></o:p></span></p> <p><span><br />1) Less labor for upkeep. <o:p></o:p></span></p> <p><span>Most growers have limited time and labor they can devote to maintaining equipment because of crop farming or an off-the-farm job. The math is pretty simple...a typical 200' long wean-to-finish building requires 20 to 22 brooders vs. five tube heaters. That's at least 15 fewer burners, switches, and valves that must be maintained. Since tube heaters operate similarly to forced air furnaces, growers are familiar with serving this type of equipment. <o:p></o:p></span></p> <p><span>Here's a link to a video on </span><a href="https://youtu.be/YS3IkFAb_qg">TUBE HEATER MAINTENANCE</a><span>. It runs through the steps needed for the annual tube heater cleaning and maintenance, along with how the burner system operates. Although shot in a chicken house, you'll get the idea. </span></p> <p><span> </span></p> <p><span>2) More reliable.<o:p></o:p></span></p> <p><span>During transition weather, both types of infrared heaters cycle on and off as the outside temperature goes up and down. Because there are more brooders, there is a greater chance one of them may not re-light. <o:p></o:p></span></p> <p><span> </span></p> <table width="471" height="43"> <tbody> <tr> <td><img src="/images/uploaded/2023 Blog/Tube Heat/Heat-Comp_900x450.jpg" alt="" width="900" height="450" /></td> </tr> <tr> <td style="text-align: center;">Thermal images highlighting the difference in heating zones.</td> </tr> </tbody> </table> <p></p> <p><span> </span></p> <p><span>3) Better heating zone<o:p></o:p></span></p> <p><span>A more evenly distributed comfort zone is the most significant advantage of using tube heat. Thermal photos comparing temperatures of brooders and tube heaters clearly illustrates the difference. The brooders tend to have a hot spot in the middle where the pigs do not lay. An integrator fieldman interviewed about his experience with tube heaters remarked, "The pigs have a much larger "happy zone" with the tube heaters. If we aren't careful, the pigs will move off the hot spot under the brooders and lay on the slats. In extreme cases, they will even start to dung under the brooders. We don't even use mats under the tube heaters for the pigs to lay on. The only mats we use are for starter feed."<o:p></o:p></span></p> <p><span> </span></p> <p><span>4) Some additional thoughts.<o:p></o:p></span></p> <p><span>Should you choose one or two-stage models? A company rep contacted for this article stated a preference for single-stage models. He said, "The two-stage uses more gas because the low fire can continually run and never quite get warm enough to cut off, all the while maintaining room temperature sufficiently, so it doesn't get cool enough for the high fire to come on either. Cycling the heater off and on at full power uses less fuel."<o:p></o:p></span></p> <p><span> </span></p> <p><span>Mount tubes at least 79 inches above a plastic floor to prevent the weakening of the plastic directly under the heater. Mounting distance from the ceiling will depend on the ceiling material. The heaters can be mounted as close as six inches with steel or aluminum ceilings. With PVC liners a strip of aluminum panel installed above the shield helps prevent warpage.<o:p></o:p></span></p> <p><span> </span></p> <p>Another observation from the integrator fieldman concerned the "wear and tear" on brooders, "After the pigs get big enough, the growers move the brooders out to storage or another building. They get banged against the gates on the way out and piled in a truck or corner somewhere. They should also bag the brooders to keep them clean if they hang them inside the room. Compare that to tube heaters permanently mounted up out of the way. Less labor and less damage from handling the heaters."</p> <p><span> </span><span>For additional reading, click on an earlier Hog Slat article titled </span><span><a href="https://www.hogslat.com/tube-heaters-for-weaned-pigs">TUBE HEATERS FOR WEANED PIGS.</a></span></p> <span></span>urn:store:1:blog:post:277https://hogslat.com/fan-shutter-heat-lossFan shutter heat loss<p><span>A 54" summer exhaust fan comes equipped with a 58"x 58" shutter (23 sq. ft.) constructed of individual 3-1/2" wide vanes.

Dirty shutters or sticky hinges prevent the vanes from closing completely. It is not uncommon to see a vane stuck in an open position because of a bent rod or even missing altogether. Heat loss through infiltration occurs when cold outside air enters through these gaps. A 58" x 58" shutter has sixteen horizontal vanes. Let's assume a gap between the vanes and each side and top. </span></p> <p><span> </span></p> <p><span>One method of calculating infiltration heat loss is known as the crack method. An older ASHRAE (American Society of Heating, Refrigerating and Air Conditioning Engineers) publication assigns a heat loss of 1 cfm per linear foot of crack.

Many variables, such as site location, wind speed, and shutter condition, will affect the actual amount of heat loss. Choosing a material with a higher R-value to close off the drafts would also decrease loss from conduction. Many producers cover the shutters with foam board, bubble pack, or even prefab closure doors to reduce heat loss to almost zero.</span></p> <p><span> </span></p> <table width="420" height="43"> <tbody> <tr> <td><img src="/images/uploaded/2023 Blog/Fan Shutter/Fan-covers_900x450.jpg" alt="" width="900" height="450" /></td> </tr> <tr> <td style="text-align: center;">Fan covers are a cost-effective method to reduce heat loss from air infiltration.</td> </tr> </tbody> </table> <p></p> <p><span>Adding fabric covers is a simple, cost-effective method to reduce loss from cold air infiltration.

Take an example of a 5'x 200' uninsulated curtain with an R-value of .73. If the outside temperature is 10 degrees and we are trying to maintain an inside temperature of 70 degrees, we can calculate a loss through the curtain of 82,200 Btus per hour. Increasing the R-factor to three reduces the Btu loss to 20,400 per hour. With average propane costs at $2.25 per gallon, this results in savings of $36.12 per day to heat the building.</span></p> <p><span>&nbsp;</span></p> <p><span>A popular alternative to insulated curtains is adding foil-backed bubble insulation. After dropping the curtain, the sheet is unrolled and placed between the bird screen and retainer ropes, holding it until the curtain is raised.

Adding exterior steel siding, 6" batt insulation with a vapor barrier, and interior sheeting increases the R-value to 19. The same 5'x 200' curtain opening now only loses 3,000 Btus per hour, resulting in fuel savings of $46.38 compared to an uninsulated curtain wall.&nbsp;</span></p> <p><span>&nbsp;</span></p> <p><span>In summary, the estimated cost to make up the heat lost through a 5' x 200' surface area for 24 hours:&nbsp;&nbsp;</span></p> <p><span>&nbsp;</span></p> <p><span>Uninsulated curtain - $48.06</span></p> <p><span>Insulated curtain &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;- $11.88</span></p> <p><span>R-19 Sidewall&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; &nbsp;- $ 1.62</span></p> <p><span>&nbsp;</span></p> <p><span>Of course, the exact cost will depend on many factors, including location in the country, local cost of fuel, average interior temperatures, and pig weights. Solid sidewalls have the additional benefit of eliminating the annual fall maintenance of curtains and curtain machines. Minimum ventilation also improves with all the air entering through inlets rather than leaks around the curtains.&nbsp;</span></p> <p><span>&nbsp;</span></p> <p><span>Consider installing two smaller generators designed to operate half of each house when changing to solid-sided walls.

The longer these air jets travel, the warmer and drier they become. Lower airspeeds mean the jets don't travel as far, causing pig-level drafts.</span></p> <p><span> </span></p> <p><span>Many older buildings incorporated gravity flow ceiling inlets for minimum and mild weather ventilation rates. This inlet style maintains adequate airspeeds (above 700 fpm) when operated with at least half its maximum rated cfm rate. The problem with gravity inlets surfaces when the amount of required air drops too low.</span></p> <p><span> </span></p> <p><span>Take the example of a 1,200-head finishing needing 48,000 cfms for mild winter ventilation. To supply this requirement, we would need to install 24 quad inlets rated at 2,000 cfm. The individual vanes would be open four inches when each inlet provides its maximum of 2,000 cfm. During very cold weather, the required cfms may drop as low as five cfm/head or 6,000 cfm total. Each inlet now supplies 250 cfm and will only be open about 1/2 inch.</span></p> <p><span> </span></p> <p><span>Small openings produce thin air streams that become too turbulent and will not travel far enough to mix properly.

Frequently just replacing the motor does not alleviate the problem; finding the root cause of the motor's failure is necessary to prevent it from reoccurring. </span></p> <p><span> </span></p> <p><span>Overheating is the most common cause of motor failure. Overheating damages the insulation protecting the motor windings allowing it to "short out." A 20-degree temperature increase beyond the rated temperature rise can reduce the insulation's effectiveness by 50%. Here are several ways to reduce overheating and increase motor life.</span></p> <p><span> </span></p> <p><span>1) Start by noting the nameplate on the existing motor showing the horsepower, rpm, voltage, hertz, phase, and frame size to select a suitable replacement. Take a photo of the nameplate and provide this to your motor supplier. </span></p> <p><span> </span></p> <p><span>2) Choose motors with a high Service Factor or S.F. The Service Factor shown on the motor plate represents the motor's ability to operate under a load that exceeds the rated H.P. of the motor. Generally, the higher the S.F., the more resistant to overheating and the more durable the engine.</span></p> <p><span> </span></p> <table width="524" height="43"> <tbody> <tr> <td><img src="/images/uploaded/2022 Blog/Motor_2/Bad-wiring_900x450.jpg" alt="" width="900" height="450" /></td> </tr> <tr> <td style="text-align: center;">Incorrect wiring caused excessive heat buildup melding the wire nuts.</td> </tr> </tbody> </table> <p><br />3) During installation, a motor may have been wired incorrectly. A misplaced wire on a dual-voltage motor allows it to run correctly a first, but it will fail prematurely. Loose spade connections cause low voltage increasing motor temperatures. Consider changing the old spade connections when replacing a motor.</p> <p><span> </span></p> <p><span>4) When remodeling a facility, the fan sizes often increase along with the horsepower requirements. Drawing more current over a long wiring circuit causes a voltage drop. When excessive, this can lead to overheating. When adding fans or replacing fans with higher capacity units, one should take the time to evaluate the wiring that feeds those fans. Increasing the wire size is often necessary when adding fans to existing facilities.</span></p> <table width="474" height="43"> <tbody> <tr> <td><img src="/images/uploaded/2022 Blog/Motor_2/Bearings_900x450.jpg" alt="" width="900" height="450" /></td> </tr> <tr> <td style="text-align: center;">Extreme temperatures melted grease and damaged ball bearings.</td> </tr> </tbody> </table> <p><span> </span></p> <p><span>5) Loose fan belts can cause excessive slippage over the motor pulley, causing its temperature to climb over 200 degrees. The motor shaft then transfers this excess heat to the interior of the motor. This transfer may cause nuisance tripping of the thermal protector and, in some cases, failure of the motor's bearings. Check and maintain correct belt tension throughout the season to prevent this from occurring.</span></p> <table width="550" height="43"> <tbody> <tr> <td><img src="/images/uploaded/2022 Blog/Motor_2/Melded-insulation_900x450.jpg" alt="" width="900" height="450" /></td> </tr> <tr> <td> <div style="text-align: center;">Excessive high temperatures caused insulation varnish to melt from windings and pool in the motor bottom.</div> </td> </tr> </tbody> </table> <p><span> </span></p> <p><span>6) The wrong size pulleys can quickly overheat a motor. While this can happen as an honest mistake, the pulleys are sometimes deliberately oversized in an erroneous attempt to increase fan performance. Increasing the pulley size even slightly causes the motor to become overloaded. Only use pulleys matching the original fan specs when replacing worn parts.</span></p> <p><span> </span></p> <p><span>When changing any motor, it is a best practice to check the operating voltage and amp draw. An electrician or qualified service tech can take measurements at the motor to verify. They then can take corrective action if the amps exceed or the voltage is below the listed motor label.</span></p> <p><span> </span></p> <p><span>This type of troubleshooting was recently illustrated on a farm experiencing reoccurring failures with a 36-inch fan motor. The voltage reading at the motor only registered 170 volts causing the fan to run slow and never reach full speed. In this instance, the motor was wired correctly with tight fasteners. Tracing the wiring back to the controller revealed a loose wire connection in a junction box. After securing the wire nuts, the motor received the full 220 volts needed to operate correctly.    </span></p>urn:store:1:blog:post:273https://hogslat.com/electric-motor-burn-out-part-1Electric motor burn out, Part 1<p><span>We typically refer to an electrical motor that has quit working as being burned out. Is that what really happens? Do the insides of a motor burn up, and is that why it stopped running? Let's take a quick look at a motor's normal operation and how it reaches a burned out state.</span></p> <p><span> </span></p> <table width="451" height="43"> <tbody> <tr> <td><img src="/images/uploaded/2022 Blog/motor_1/Motor-Dia_900x450.jpg" alt="" width="900" height="450" /></td> </tr> <tr> <td style="text-align: center;">Inside view of a motor</td> </tr> </tbody> </table> <p></p> <p><span>Inside a motor, there is a band of copper wire called the windings. As current flows through the windings, it creates a rotating magnetic field, causing the motor shaft to rotate. The motor will continue to operate if the windings receive a steady, stable electrical supply. Insulating varnish is applied to the windings to ensure electricity flows through the entire coil. Without this insulation, the current would flow across the wires, causing a short circuit.</span></p> <p><span> </span></p> <p><span>Farm Duty motors have a design factor allowing them to operate at temperatures as high as 200 degrees. The insulation varnish can withstand temperatures as high as 300 for short periods. Under normal operating conditions, the varnish coating adequately protects the windings preventing short-circuiting.</span></p> <p><span> </span></p> <div> <table width="521" height="43"> <tbody> <tr> <td><img src="/images/uploaded/2022 Blog/motor_1/Windings_900x450.jpg" alt="" width="900" height="450" /></td> </tr> <tr> <td style="text-align: center;">Comparison of new and damaged motor windings</td> </tr> </tbody> </table> </div> <p></p> <p><span> </span></p> <p><span>When the internal temperature of a motor repeatedly rises above its typical operating temperatures, the varnish coating becomes damaged. This damage allows the electrical current to short-circuit across wires without completing its normal travel path through the windings. Reducing the circuit increases the heat output, further damaging the insulation. A stable voltage supply no longer exists, and the shaft fails to turn. In severe cases, the wiring becomes so hot the insulation varnish melts and pools in the bottom of the motor housing.</span></p> <p><span> </span></p> <p><span>The reasons causing a motor to overheat are varied. These include improper wiring, loose connections, or undersized line sizes causing a voltage drop at the motor. In other instances, slippage from loose belts transfers heat to the motor through the shaft. Choosing the wrong size replacement pulley can also quickly overload the engine.</span></p> <p><span> </span></p> <p><span>Preventing motors from being damaged by overheating begins by selecting a suitable replacement motor along with installing and wiring it correctly. Situations, where motors fail repeatedly, are probably not due to manufacturing defects. In these cases, looking deeper for an underlying cause is necessary. In part 2, we will discuss steps to prevent motors from overheating.</span></p>urn:store:1:blog:post:272https://hogslat.com/reliable-backup-systems-are-no-accidentReliable backup systems are no accident.<p><span>Begin with examining the existing wiring scheme of the fans, controllers, and override thermostats. A common mistake is wiring the first override thermostat on the same breaker as the controller, causing both to fail if the breaker is lost. Also, verify the override thermostat controls the first large summer ventilation fan. Set the override thermostat six to eight degrees above the controller set point for that stage. Adjust the override thermostat to maintain this spread as the controller's temperature curve decreases the building set point.  </span></p> <p><span> </span></p> <p><span data-preserver-spaces="true"><span>Buildings outfitted with curtain drops provide an effective method for protecting against loss during power outages.

For direct cooling to work efficiently, the pig's skin should be thoroughly wetted and then allowed to dry completely. The wetting and drying cycle is a critical part of the process. If the pigs are continuously wet, the humidity rises, reducing the amount of cooling by evaporation.</p> <p> </p> <p>This wetting and drying cycle is key to maximizing the cooling effect. First, set the on-cycle to thoroughly wet the pen area, usually two to four minutes. Next, shut the fogger system off, and note how long it takes for the pen and pigs to dry off completely. This period becomes the off-cycle on the controller. The off time will vary; in areas of the country with high humidity, this period can be as long as an hour. Lower humidity can reduce the off-cycle to as low as 15-20 minutes. The most common mistake is not allowing enough off time for the pen to dry.</p> <p> </p> <table width="529" height="43"> <tbody> <tr> <td style="text-align: center;"><img src="/images/uploaded/2022 Blog/Sprinkler-Evap/Fogger-control_900x450.jpg" alt="" width="900" height="450" /></td> </tr> <tr> <td style="text-align: center;">The control should include a 24-hour time to shut the system off at night</td> </tr> </tbody> </table> <p> </p> <p> </p> <p>You will also need to include a 24-hour timer to shut the system off at night.

Mounting the foggers 54 inches high along the outside pen walls, with the nozzles pointing down at a 45° angle, provides the correct area for wetting the pen. To get accurate coverage in the pen area, choose a nozzle that emits coarse droplets that will fall quickly to cover a specific location. One example of the proper nozzle is Hog Slat's part number<a href="https://www.hogslat.com/34-fogger-with-tee"> 61025</a>, emitting a medium-sized droplet of about 250 microns. The ASABE standard describes this as similar to a "heavy drizzle."</p> <p> </p> <p>Effective evaporation only occurs when there is substantial air movement across the pigs. Tunnel ventilated buildings supply sufficient airflow at 300 to 400 feet per minute. For naturally ventilated buildings, it is necessary to add stir fans to provide air movement when there is no outdoor breeze. The effective thrust of a fan is 2X (in feet) of its diameter.</p> <p>For example:</p> <p>18" fan - 36'</p> <p>20" fan - 40'</p> <p>24" fan - 48'</p> <p></p> <table width="517" height="43"> <tbody> <tr> <td><img src="/images/uploaded/2022 Blog/Sprinkler-Evap/stir-fan-layout_900x450.jpg" alt="" width="900" height="450" /></td> </tr> <tr> <td style="text-align: center;">Racetrack or cross-staggered stir fan layout</td> </tr> </tbody> </table> <p> </p> <p></p> <p>Choose from either racetrack or cross-staggered patterns to ensure proper air movement.

Yes, we have gates that swing and feeders with paddles or levers, but it's not the same. The internal trigger gate and the rear gate must move smoothly without binding and do it continuously for years.</p> <p> </p> <p>Hog Slat began the process of developing FAS over seven years ago by visiting existing producers across Europe. After studying where FAS failed and succeeded, we produced our first prototype for testing in Germany and North Carolina farms. The finished product you see now is our 5th version. Getting there required a lot of work.</p> <p> </p> <p>Balance</p> <p>Hog Slat engineers used a computer simulation to locate the exact location of the hinge point for the correct balance between the gates. This simulation allowed for testing different rear gates, trigger gates, widths, and stall length configurations.</p> <p> </p> <table width="484" height="43"> <tbody> <tr> <td><img src="/images/uploaded/2022 Blog/FAS/Pivot_900x450.jpg" alt="" width="900" height="450" /></td> </tr> <tr> <td style="text-align: center;">Rugged, fixed pivot point with stainless steel bushing</td> </tr> </tbody> </table> <p> </p> <p>Hinge Point</p> <p>For long-term durability, the hinge point must be stable without any "play" and stay that way. Hog Slat's hinge points are large steel bushings welded in the moving doors. They rotate on stainless steel inserts fixed tightly against the stall side. The hinge point passed a longevity test of 300,000 automated activation cycles representing 40 years of on-farm use. This hinge and the balance are the most significant differences between Hog Slat's stall and others on the market. Less robust hinges will loosen over time and prevent the smooth operation of the gates.</p> <p> </p> <p>Lineage</p> <p>The connection between the rear gate and the front gate must not have any flex. Hog Slat uses a single tube for the linkage with a slight adjustment to set the gate balance. The single linkage rod also gives an AI tech more room when breeding. To test the linkage, we locked the gates shut and repeatedly slammed 500 pounds of force against it, checking for bending and cracking.</p> <p> </p> <p> </p> <p> </p> <table width="504" height="43"> <tbody> <tr> <td><img src="/images/uploaded/2022 Blog/FAS/Leg_900x450.jpg" alt="" width="900" height="450" /></td> </tr> <tr> <td style="text-align: center;">Stainless steel legs rotate 360°</td> </tr> </tbody> </table> <p></p> <p>Adjustable legs</p> <p>Hog Slat's stainless steel legs fit inside a stainless steel stall sleeve, making them independently adjustable for height. This height adjustment is critical on uneven floors as smooth operation of the stall depends on installing the stalls level. The legs also rotate 360° to enable secure fastening to the slats or floors.</p> <p> </p> <table width="496" height="43"> <tbody> <tr> <td><img src="/images/uploaded/2022 Blog/FAS/lever_900x450.jpg" alt="" width="900" height="450" /></td> </tr> <tr> <td style="text-align: center;"> Robust locking system will lock up to 25 stalls with a single lever.</td> </tr> </tbody> </table> <p></p> <p> </p> <p>Locking lever</p> <p>A vital management feature of FAS stalls is the ability to lock a row of sows in place. Hog Slat's robust locking system will lock up to 25 stalls with a single lever smoothly without binding. There are also provisions for locking individual sows in for special treatment.</p> <p> </p> <p>Tubular construction</p> <p>Stability is an absolute must for the proper operation of Free Access Stalls. Solid rods do not have the same rigidity as a tube and will flex slightly as the gates activate, causing a slight amount of binding.  </p> <p> </p> <p>Standard 24-inch width</p> <p>Changing the width means changing the gate weight, which changes the system's balance. The standard 24-inch width allows ample room for breeding while fitting into most pen configurations.</p> <p> </p> <p>Making the facility changes for Prop 12 and other welfare regulations requires a substantial capital investment.  Along with supplying your operation with a proven product, Hog Slat also provides expertise in equipment layout for new construction or remodeling projects. Several installations have included incorporating Free Access Stalls between ESF feeding stations or integrating them into stanchion systems for individual sow treatment. <a href="https://hogslat.com/global/flyers/hog-slat-free-access-stall-flyer/">CLICK</a> to learn more.</p>urn:store:1:blog:post:265https://hogslat.com/level-up-your-fly-controlLevel up your fly control<p><strong>Understand the three levels of fly activity for more effective control</strong><br /><br />Flies on hog or poultry farms are more than a nuisance; they carry diseases that can pose a severe health hazard to people and animals. Fly control is a basic component of biosecurity in hog and poultry houses.</p> <p> </p> <p>Given the housefly's seven-day life cycle and the almost perfect environment conditions livestock and poultry facilities provide, it is no wonder populations can increase rapidly.

But with a producer spending an hour per day, on average, managing a finishing barn, a well-designed ventilation system should minimize the time spent adjusting air inlets.</p> <p> </p> <p>Many existing facilities use gravity flow ceiling inlets (bifold, quad, or drop doors models) to introduce fresh air during the winter and transition periods. These inlets rely on counterbalance weights or springs to regulate the amount and speed of the incoming air based on static pressure. This style of inlet has several limitations.</p> <p> </p> <p>1) It can be challenging to calibrate the inlets in the room the same because of the variance in baffles, counterweights, and installation.</p> <p> </p> <p>2) As the system goes into tunnel mode, the inlets remain open, allowing the fans to pull hot air from the attic.</p> <p> </p> <p>3) During minimum vent, the baffle openings become very small, creating thin streams of airflow that lack the volume to push along the ceiling far enough to warm before tumbling to animal level.</p> <p> </p> <p>4) The baffles and vanes are also prone to "sticking" as dust accumulates.</p> <p> </p> <p>These limitations are overcome by locking and unlocking baffles, cleaning, and making any other corrective measures needed.

Considering it typically takes two people at least 30 minutes to remove a dead sow with a manual system, the one-person operation of a Hercules' Arm becomes a much more affordable option.</p> <p> </p> <p>While the needs of individual farms will vary, providing farmworkers with the proper removal equipment will allow them to perform this difficult task quickly with minimal threat of injury.     </p>urn:store:1:blog:post:252https://hogslat.com/smart-farming-with-free-access-stallsSmart farming with free access stalls<p>Today ag news is full of information about the latest digital equipment promising to revolutionize farming.  Nowhere is this attitude more prevalent than the topic of group sow housing.  But technology and innovation doesn’t mean that the solution must consist of electronics, PLCs, and connectivity to the internet.  It can be innovative designs that resolve production issues and improves your bottom-line profitability.</p> <p> </p> <p>Free Access Stalls (FAS) offer a unique solution to group sow housing that is labor-friendly.   FAS combines standard equipment, the sow stall, with an animal-activated access gate.  Farm labor isn't really required to learn new skills.  Individual sows can be locked in place for supplemental feeding, breeding, or treatments.</p> <table width="493" height="48"> <tbody> <tr> <td><img src="/images/uploaded/2022 Blog/SMART FAS/FAS-Activate_900x450.jpg" alt="" width="900" height="450" /></td> </tr> <tr> <td> <div style="text-align: center;">Sow lifts the front trigger gate locking the rear door down behind her.</div> </td> </tr> </tbody> </table> <p> </p> <p>The feeding system is also familiar to farm labor. It's the same auger system with adjustable feed drops used for years in stall configurations. Maintenance personal already possess the skills needed to replace a feed line motor or relay switch.  Compare this to ESF systems and the skills needed to repair electronic components or troubleshoot internet connections.</p> <p> </p> <p>Maybe you have noticed the escalating auction prices for older tractors.  Besides a shortage of new equipment, this increasing demand is also driven by farmers' desire to own equipment that can be repaired on the farm. The same is true for computerized feeding systems.  Once you commit to a brand of ESF equipment, you must rely on that company for repair parts.  While you can shop a replacement feed motor, you cannot price around for a replacement circuit board. </p> <p> </p> <table width="471" height="42"> <tbody> <tr> <td><img src="/images/uploaded/2022 Blog/SMART FAS/Sow-in-FAS_900x450.jpg" alt="" width="900" height="450" /></td> </tr> <tr> <td style="text-align: center;">Sows choosing to lounge in FAS.  Each stall provides refuge to individual sows.</td> </tr> </tbody> </table> <p> </p> <p>There is a solid case to be made for FAS being the most welfare-friendly system.  In ESF systems, much attention is paid to providing escape areas for less dominant animals, such as T pen layouts and extra dividing walls.  With FAS systems, each stall is an escape area where individual sows can seek refuge.   One of the most common reactions after viewing a FAS building is surprise at the number of sows choosing to lounge in the stalls.</p> <p> </p> <p>Free Access Stalls can also function with existing ESF, stanchion, or other group housing systems currently utilizing stalls for breeding.   Replacing those standard stalls with FAS provides a welfare compliance solution that provides individual care during breeding and preg checking. </p> <p> </p> <p>Technology has its place in modern swine production.  No one would suggest returning to mechanical thermostats to control ventilation.  Computerized controls and sensors provide a much more accurate solution to managing building environments.  Record keeping has also benefited from electronic collection with handheld RFID readers scanning individual sow tags allowing caretakers to record data accurately.</p> <p> </p> <p>Producers should evaluate every new technology through the lens of whether it contributes to the farm's overall profits.  FAS offers a cost-effective, more labor-friendly solution to welfare concerns for sow housing.   <a href="https://hogslat.com/global/flyers/hog-slat-free-access-stall-flyer/">Click</a> for more information on Free Access Stalls.  <a href="https://youtu.be/-2Q-jOvcvms">Click</a> to view a video of the FAS in use.  </p>urn:store:1:blog:post:251https://hogslat.com/motor-nameplate-key-to-selecting-replacementsMotor nameplate key to selecting replacements.<p><span>Livestock and poultry operations subject electric motors to very hostile work environments. Those environments alternate between dusty and humid, along with fluctuations in voltage and changing workloads.  <o:p></o:p></span></p> <p><span> </span></p> <p><span>When selecting replacement motors, it is important to choose motors that are energy efficient and designed with a built-in "safety factor" that allows them to last under harsh conditions. <o:p></o:p></span></p> <p><span> </span></p> <p><span>While Service Factor or S.F. may be a familiar term., there are a couple of important designations found on a motor nameplate that may need more clarification.<o:p></o:p></span></p> <p><span> </span></p> <p><span>Service Factor is the motor's ability to operate under an increased short-term load. The higher a motor's S.F. rating is the more durable the motor. To illustrate, a 1-1/2 hp motor with a 1.5 S.F. can provide 2.25 hp of power for a short period. However, it is not good to continuously operate a motor above the rated workload. For example, it would not be a good idea to use the same 1-1/2 hp, 1.5 S.F. motor to replace a 60" fan initially designed to operate with a two hp motor.<o:p></o:p></span></p> <p><span> </span></p> <p><span>Full Load Amps, or F.L.A., represents<s> </s>the amount of current the motor will draw at its rated horsepower. In the example nameplate, when operating at a full load at 230 volts, we can expect it to draw 5.4 amps. When choosing between two motors with the same horsepower, a lower F.L.A. is more efficient.<o:p></o:p></span></p> <p><span> </span></p> <p><span>Service Factor Amps, or S.F.A., represents the current the motor will draw when running at its full Service Factor. In the example nameplate, the S.F.A. is eight amps at 230 volts. Continually exceeding the S.F.A. shown on the nameplate can shorten motor life. Motors with a higher S.F.A. have an increased "safety factor" to last longer under harsh conditions.<o:p></o:p></span></p> <p><span> </span></p> <p><span>The most efficient, rugged motors have higher S.F., lower F.L.A., and higher S.F.A. ratings. By comparing the information on a motor nameplate, we can select the best replacement motors for a farm's feeding and ventilation equipment.  <o:p></o:p></span></p> <p><span> </span></p> <p><span>For more information, see </span><a href="https://www.hogslat.com/grower-select-electric-feedline-auger-and-fan-motors">GrowerSELECT</a><span> replacement motors.<o:p></o:p></span></p>urn:store:1:blog:post:250https://hogslat.com/slat-replacement-with-altenburg-constructionSlat replacement with Altenburg Construction<p>Over the last 27 years, Altenburg Construction has built a reputation as the Midwest's slat replacement professionals.  We caught up with the owner, Andy Altenburg, to discuss what to look for when evaluating slats in an existing facility.<br /><br /></p> <table width="572" height="51"> <tbody> <tr> <td><img src="/images/uploaded/2021 Blogs/Altenburg/Andy_900x450.jpg" alt="" width="900" height="450" /></td> </tr> <tr> <td> <div style="text-align: center;">Andy Altenburg, owner of Altenburg Construction</div> </td> </tr> </tbody> </table> <p></p> <p>HSI: At what point should an owner start looking for problems with slats in a building?</p> <p> </p> <p>Andy:  This really varies with the brand of slat and the individual building, but in general, we start to recommend doing a detailed examination at about 15 years of age.  Of course, if you notice slats that are rocking, have dropped down slightly, or have premature wear, then that evaluation needs to be done immediately.</p> <p> </p> <p>HSI:  What should an owner do to perform a detailed examination of the slats?</p> <p> </p> <p>Andy:  First of all, look for wear on the surface of the slats, especially around feeders and waterers.  Not only are we looking for surface wear, but we also check the width of the slat opening.   As slats age, we commonly see the slat opening enlarging, causing possible welfare issues.  We then take a bright LED light and look at the bottom of the slats and beams.</p> <p> </p> <table width="544" height="42"> <tbody> <tr> <td><img src="/images/uploaded/2021 Blogs/Altenburg/Beam-damage_900x450.jpg" alt="" width="900" height="450" /></td> </tr> <tr> <td style="text-align: center;">Beam showing damage from internal rusting and rebar expansion</td> </tr> </tbody> </table> <p></p> <p>HSI:  What are you looking for when examining the beams?</p> <p> </p> <p>Andy:  We are checking the bottom of the beam looking for a nice, straight edge.  If the bottom is jagged, that means part of the beam has sloughed off.  We then look about 1-1/2" up for cracks.  Either of these conditions means the rebar inside has started to rust and expand.  The beams are the part that most people don't examine closely enough for damage.</p> <p> </p> <p> </p> <p>HSi: If slat and beam damage is there, what happens next?</p> <p> </p> <p>Andy:  The owner contacts us, and we will come out to estimate the job and set up a timeline for replacing the slats.  We will determine who's responsible for removing the equipment, disposal of the old slats, and reinstalling the building's equipment.   We always handle the transportation of the slats to ensure they are there on time.</p> <p> </p> <p> </p> <p> </p> <p>HSI:  Is every job a complete replacement of the slats?</p> <p> </p> <p>Andy: Not always.

Every year losses occur because the generator fails to supply service during a power outage. </p> <p>To avoid generator malfunctions, livestock producers should establish a routine maintenance program for farm generators.</p> <p> </p> <p>Weekly maintenance</p> <p>1) Monitor the generator's automatic run cycle, verifying the unit ran without alarms or warnings.</p> <p>2) Confirm the unit is in "auto" mode.</p> <p>3) Visually check for fuel leaks.</p> <p>4) Ensure the circuit breaker is closed.</p> <p>5) Check fuel level.</p> <p> </p> <p>Monthly maintenance</p> <p>1) Check the battery charger.</p> <p>2) Check engine oil level.</p> <p>3) Check coolant levels.</p> <p> </p> <p>Yearly maintenance (with a certified technician)</p> <p>Manufacturers may have a more expanded list, but at minimum, the annual maintenance should include the following items.</p> <p>1) Change the oil and filter.</p> <p>2) Change the fuel filter.</p> <p>3) Change the battery (every two years).</p> <p>4) Check the exhaust system.</p> <p>5) Inspect the wiring.</p> <p>6) Inspect the belts.</p> <p>7) Change the spark plugs.</p> <p>8) Check electrical breakers, replace if suspect.</p> <p>9) Check the cooling system and hoses.  Stock coolant and spare hoses.</p> <p>10) Perform load bank testing. (Artificial load placed on the generator verifying it's performing at full capacity. Helpful in pinpointing any weak components.)</p> <p> </p> <p> </p> <p> </p> <p>Farm management may also consider entering into an annual service contract with their generator supplier. Along with the scheduled maintenance program, a typical agreement provides for on-site emergency service calls.</p> <p> </p> <p>Every farm should have a load management plan in place to balance the generator output with the electrical loads.  In many cases, the generator is not sized to run the farm's electrical system at full capacity. A load management plan details which equipment should be activated when the farm is operating on emergency power. For example, the plan could call for shutting off the tunnel fans in a gestation/breeding building and lowering the curtains for ventilation. While in the farrowing house, the fans would continue to operate, but half the heat lamps would be switched off.</p> <p> </p> <p>Even with a generator sized to power the entire facility, it is prudent not to tax the system to capacity. Check the running load and if in doubt, take any unnecessary equipment offline to provide a margin of error.  Just assuming the generator is capable of running the entire facility is risky. It is crucial to monitor and manage an operating generator.</p> <p> </p> <p> </p> <p>Responsible operation of a generator means monitoring the amount of available fuel. Instead of relying on a sight gauge, use a simple fuel dipstick. Make one from ¾ inch wooden dowel rod designated with 1/4, 1/2, 3/4, and FULL marks. Insert the dipstick into the tank and visually check the fuel level. Also, post the expected run time for each fuel level near the generator. The operator can then estimate how long the facility will stay powered according to the current fuel level.</p> <p> </p> <table width="496" height="42"> <tbody> <tr> <td><img src="/images/uploaded/2021 Blogs/Generator/Gen-Tank_900x450 copy 2.jpg" alt="" width="900" height="450" /></td> </tr> <tr> <td style="text-align: center;">After generator startup, the farm manager should verify the amount of fuel in the supply tank.</td> </tr> </tbody> </table> <p></p> <p>After generator startup, the farm manager should verify the amount of fuel in the supply tank. Don't assume there is adequate fuel and leave the farm, only to find out later the generator ran out of fuel several hours later. The operator should continue to check the fuel level noting any variations from the estimated run times. Powering the farm during weather extremes, such as operating large fans in the summer or heating systems in the winter, can easily cause the generator to use more fuel than estimated.</p> <p> </p> <p>Remember a facility running on standby power has no fallback position.  Performing routine generator maintenance and detailing an operating plan helps to ensure the health and well being of our animals during power outages.</p> <p> </p>urn:store:1:blog:post:248https://hogslat.com/fine-tune-your-farms-backup-systemsFine tune your farm’s backup systems<p><span>Begin with </span><span>examining the actual wiring scheme of the fans, controllers, and override thermostats.

Smart rodent control anticipates this annual fall movement.</p> <p> </p> <p>Begin by placing baits in enclosed stations along the outside perimeter of your facilities. Stations protect baits from rain and dirt, helping the rodenticides stay fresh and potent longer while providing security against access from children and pets.  Bait stations also provide an environment where rats and mice feel secure when feeding on baits. </p> <p> </p> <p>Early placement is vital because rodents are suspicious of new objects; entering a new bait station may take several weeks.   Standard recommendations call for placing stations 8-12 feet apart for mice and 15-30 feet for rats. When rats are present, do not use mouse stations as the bigger rodents will gnaw through the thinner plastic and expose the baits.  Consider using white-colored bait stations for those locations on the south exposure of buildings. The interior temperature of black-colored stations can increase by as much as 30°.</p> <p> </p> <p>The most popular models of bait stations can be mounted horizontal or vertical to reduce their footprint. They also feature an entry/exit design that lures rodents in for feeding.

The off time will vary; in areas of the country with high humidity, this period can be as long as an hour.  Lower humidity can reduce the off-cycle to as low as 15-20 minutes.  The most common mistake is not allowing enough off time for the pen to dry.</span></p> <p><span> </span></p> <p><span>The type of fogger or sprayer nozzle used is important for getting the correct amount of coverage in the pen.   For many years Hog Slat has used an 80° nozzle (</span><a href="https://www.hogslat.com/34-fogger-with-tee"><span>see 61025</span></a><span>) emitting a medium-sized droplet of about 250 microns.  The ASABE standard describes this as being similar to a "heavy drizzle."   This droplet size does not drift in the air, which raises humidity, but drops quickly to cover a given area of the pen.</span></p> <p><span> </span></p> <table width="808" height="42"> <tbody> <tr> <td style="text-align: center;"><img src="/images/uploaded/2021 Blogs/Fogger/Sprinkler-nozzle_900 copy.jpg" alt="" width="900" height="450" /></td> </tr> <tr> <td style="text-align: center;"><span>Select a nozzle emitting medium droplets that will fall quickly to avoid raising the humidity.</span><span></span></td> </tr> </tbody> </table> <p><span> </span></p> <p><span>Also, configure the system to wet no more than half the pen.  Mounting the foggers 54” high along the outside pen walls, with the nozzles pointing down at a 45° angle, provides the correct area for wetting the pen.</span></p> <p><span> </span></p> <p><span>Adequate air movement is also critical to drying the pigs between spraying cycles.  For optimum cooling, strive for an air velocity of 300 fpm at pig level.  While this is not a problem for mechanically ventilated tunnel systems, natural curtain systems will require assistance from stir fans.  The effective thrust of a stir fan is roughly 2X (in feet) of its diameter.</span></p> <p><span> </span></p> <p><span>For example:</span></p> <p><span> </span></p> <p><span>18" fan - 36'</span></p> <p><span>20" fan - 40'</span></p> <p><span>24" fan - 48'</span></p> <p><span> </span></p> <p><span> </span></p> <table width="585" height="42"> <tbody> <tr> <td><img src="/images/uploaded/2021 Blogs/Fogger/Stir-fan-layout_900 copy.jpg" alt="" width="900" height="450" /></td> </tr> <tr> <td style="text-align: center;"><span>Choose from a racetrack or cross-staggered stir fan layout.</span><span></span></td> </tr> </tbody> </table> <p><span> </span></p> <p><span> </span></p> <p><span>Here are a couple of typical layouts using 20” fans for a 40' x 200' finishing house with a racetrack and cross-staggered patterns.  Angle the fans in the racetrack pattern at about 20° towards the middle. </span></p> <p> </p> <p><span>You can fine-tune the management of your fogger system by making some minor adjustments to increase its effectiveness.</span></p> <p> </p> <p> </p>urn:store:1:blog:post:242https://hogslat.com/free-access-stalls-live-action-videoFree Access Stalls live-action video.<p>Hog Slat's Free Access Stall provides the animals with freedom of movement in and out of the stalls while allowing caretakers the ability to restrain individual sows for insemination, preg checking, supplement feeding, and other tasks.</p> <p> </p> <p>In combination with Hog Slat's stanchion equipment, our Free Access Stall gives producers a management-friendly group housing system that meets welfare concerns without complex maintenance and communication issues typical with electronic sow feeding.</p> <p> </p> <p>Watch this short <a href="https://youtu.be/-2Q-jOvcvms">video</a> of an installation showing sows activating the trigger gates to move in and out of the Free Access Stalls.</p>urn:store:1:blog:post:241https://hogslat.com/is-your-insurance-keeping-up-with-increased-building-costsIs your insurance keeping up with increased building costs?<p><span>If you haven't priced a new confinement building recently, you may be surprised at the increase in prices. "We have seen a drastic rise in new construction costs," said Fritz Richards, Hog Slat's National Sales Manager. "Increases in lumber, steel, concrete, and labor have all contributed to pricing that is roughly 20% higher than last year." <o:p></o:p></span></p> <p><span> </span></p> <p><span>This increase means that a facility on your farm that cost $500,000 to build several years ago now has a replacement cost closer to $600,000. <o:p></o:p></span></p> <p><span>Even if your policy includes an automatic inflation guard to cover annual inflation, your coverage has probably not kept pace with this unexpected spike in building costs.  To be protected against loss, your coverage should equal the cost to rebuild it.<o:p></o:p></span></p> <p><span> </span></p> <p><span>It is also important to know how the insurer calculates the actual value to replace the facility. Actual Cash Value (ACV) and replacement cost value (RCV) are methods that insurance companies use to assign value to the property. ACV reimburses you for lost property with depreciation included. It looks at current replacement costs and subtracts for age and overall condition of the barn. It is not likely to fully replace your building. RCV assigns value without factoring in depreciation. It pays the total replacement value minus any deductible.  <o:p></o:p></span></p> <p><span> </span></p> <p><span>The difference in premium can be <em><span>substantial, so choosing</span></em><i> </i>which coverage is best for you depends on your situation. RCA coverage will typically be more expensive but offers peace of mind if your facilities are damaged or lost. In some cases, your lender may require you to pay for RCA to protect their loan. A less expensive ACV policy may a better option if your operation has the means to cover the costs of replacing or repairing the structure. <o:p></o:p></span></p> <p><span> </span></p> <p><span>Another situation in which an ACV policy might be a better choice relates to older buildings. Most RCV policies contain a provision requiring only the payment of the ACV amount until the repairs are actually completed. The insured is then entitled to the "holdback" or the difference between ACV and the full payment. If the owner doesn't plan to replace an aged building if lost or damaged, they will not receive the RCV payment.<o:p></o:p></span></p> <p><span> </span></p> <p><span>Most insurance policies also contain a coinsurance provision that requires you to insure your building value at 80% to 100% of the value needed to replace the building.  If you are buying insurance at the old cost, you could suffer a coinsurance penalty and not recover the full replacement cost.<o:p></o:p></span></p> <p><span> </span></p> <p><span>$500,000 Insured Value<o:p></o:p></span></p> <p><span>$600,000 Replacement Value<o:p></o:p></span></p> <p><span>80% Coinsurance = $480,000 required<o:p></o:p></span></p> <p><span>Adequately insured based on 80%, but the insurer only pays the insured value of $500,000 for the claim.<o:p></o:p></span></p> <p><span> </span></p> <p><span>$500,000 Insured Value<o:p></o:p></span></p> <p><span>$600,000 Replacement Cost<o:p></o:p></span></p> <p><span>100% Coinsurance = $600,000 required<o:p></o:p></span></p> <p><span>Insurer is obligated to pay only 83% ($498,000) and you coinsure 17% ($102,000).<o:p></o:p></span></p> <p><span> </span></p> <p><span>Excluding land, confinement buildings are one of the largest purchases a farm owner will make.

The heat isn't destroyed but instead changes to another form, water vapor. So the incoming </span><span>air <span>is now cooler but its humidity </span>has<span> also increased. The drier the air, the more potential cooling is possible. 90° air with 20% humidity has the potential to be cooled to 67°, while the same 90° air with 60% humidity has only the potential to drop to 86°.

As temperatures reach 80° by midmorning, the humidity drops below 80%, and evaporative cooling is now effective. The same holds true in the evening; as the temperature cools to below 80°, the humidity will rise above 80%, diminishing the evap system’s effectiveness. It is difficult to evaporate additional water when the air is already saturated. Typically there is very little value in operating a cool cell system between 10 pm and 10 am as a general rule.  </p> <p><span> <br /></span><strong><span>Dry the pads out.</span></strong><span> </span></p> <p><span>Some producers operate their system with the idea that even a little cooling is beneficial, so why not run the pads continuously? Not allowing the evaporative pads to dry each day will severely shorten their useful life. Think of it this way - evap pads are a treated paper product. If you let a cardboard box stay wet, it will eventually collapse and lose its shape. If that same box dries out each day, it will keep its form much longer. Same with cool cell pads. A five-foot pad weighs about 5-1/2 pounds dry. When it is fully saturated, it could easily double in weight. The extra weight causes the pads to fail structurally over time. The more time a pad spends with this extra weight, the quicker it fails. Allowing the pads to dry each night between 10 pm and 10 am extends their useful life.</span></p> <p><span> </span></p> <p><strong><span>Airspeed is key</span></strong></p> <p><span>The evaporative pads are only part of the cooling system. The key to maximizing the effectiveness of an evaporative cooling system is moving air at high velocities with tunnel fans. Going back to our earlier example of the 70° summer morning with high humidity highlights this principle. If there is a breeze blowing, the temperature seems pleasant. If the wind is calm, the weather feels hot and muggy. The graph in Figure 2 illustrates the wind chill effect of 85° F air at various wind speeds. 85°air feels like 75° air when it is moving at 500 feet per second. It does little good to operate an evaporative cooling system without adequately designed and maintained tunnel fans delivering sufficient airspeed.</span></p> <p><span> </span></p> <table width="658" height="42"> <tbody> <tr> <td><img src="/images/uploaded/2021 Blogs/Common Sense Evap/Fig.2_Wind_Chill_900.jpg" alt="" width="900" height="450" /></td> </tr> <tr> <td style="text-align: center;">Data from North Carolina State University</td> </tr> </tbody> </table> <p></p> <p>There is no mystery to operating an evaporative cooling system effectively.  You can observe the environment around you to make some common sense choices on how that system performs.</p>urn:store:1:blog:post:239https://hogslat.com/new-hog-slats-magnum-feeder-seriesNew!

Move enough air over the pigs in the summer to cool them. In the winter, we dial in the exhaust rate needed to maintain air quality and humidity without burning excessive heat.<o:p></o:p></span></p> <p><span> </span></p> <p><span>Transition ventilation is the in-between period…when minimum ventilation is not enough air and the system has not switched to summertime airflow. It's those days that bounce between lows in the 30s at night and the 70s in the afternoon.<o:p></o:p></span></p> <p><span> </span></p> <p><span>We calculate the amount of transition ventilation needed to be about one-third of the maximum rate. For example, the maximum rate for a finishing pig is 120 cfm, meaning we need to provide 40 cfm for the transition period. Typically this cfm rate is staged from minimum to maximum with several smaller fans or one larger variable speed fan.<o:p></o:p></span></p> <p><span> </span></p> <p><span>The management part of this transition phase is adjusting the air inlets to maintain a high-velocity air jet of 700 to 1,000 feet per minute. At this speed, the cool air sweeps across the ceiling mixing with the warmer room air before tumbling to pig level. If an inlet is too far open, the air enters at too low of speed, sinking to the floor without mixing, causing drafts.<o:p></o:p></span></p> <p><span> </span></p> <p><span>Early ventilation systems used hand-operated baffles. The common method of managing the baffles was to set them in the morning during the coolest part of the day. As the day warmed up and fans started to cycle on, the static pressure increased inside the building. If possible, the herdsmen would open the baffles during the middle of the day and try to remember to shut the baffles down as the day cooled down and the fans switched off.<o:p></o:p></span></p> <p><span> </span></p> <p><span>Gravity actuated inlets represent the second generation of air inlets. These inlets use a weight or spring to counterbalance an inlet baffle or vane that opens with increasing static pressure. While a big improvement over manual inlets, these passive inlets required manual adjustment during the transition period.<o:p></o:p></span></p> <p><span> </span></p> <table width="669" height="42"> <tbody> <tr> <td><img src="/images/uploaded/2021 Blogs/Managing Transition Vent/Gravity-Inlet-900.jpg" alt="" width="900" height="450" /></td> </tr> <tr> <td style="text-align: center;">  Low airspeeds can cause drafts at floor level during cold weather</td> </tr> </tbody> </table> <p>One of the inherent flaws of gravity flow inlets is their inability to deliver the needed high-velocity air at minimum ventilation if there are too many inlets. For instance, in a 1,000 finishing building, the transition cfm requirements would be 40,000 cfms. It would take 20 of the commonly used 2,000 cfm quad inlets to satisfy this demand. During minimum rates with weaned pigs, the ventilation is now 3,000 cfms, meaning each inlet only needs to supply 150 cfms. The result is low-speed air streams that do not mix with the surrounding room air causing uneven air distribution.</p> <p><span> </span></p> <p><span>The way to correct this is to close down some of the inlets. If we take the minimum cfm rate of 3,000 and divide it by 500 cfm, it would take six ceilings inlets. We would open six of the inlets and shut down the other 14 inlets. The problem would be the building operator would need to open additional inlets as the temperature warmed. While good management would allow this system to function well, it is less than ideal.<o:p></o:p></span></p> <p><span> </span></p> <table width="650" height="42"> <tbody> <tr> <td><img src="/images/uploaded/2021 Blogs/Managing Transition Vent/Act-Inlet-900.jpg" alt="" width="900" height="450" /></td> </tr> <tr> <td style="text-align: center;"> <div> Automated inlets maintain high airspeeds to prevent drafts at floor level. </div> </td> </tr> </tbody> </table> <p><span> <o:p></o:p></span></p> <p><span> </span></p> <p><span>An automated system represents the third generation of air inlets.

Second, infrared beams are not affected by excess moisture and feed buildup on the control's interior.  To demonstrate, we sprayed water on the control's interior, allowing feed dust to cake on the walls.  Even in this extreme condition, the controller continued to operate without failure.</p> <p> </p> <p>Hog Slat's newest feed line control, the HS820, uses infrared technology along with a color-coded display to quickly inform the user of its operational mode.</p> <p> </p> <table width="678" height="42"> <tbody> <tr> <td><img src="/images/uploaded/2021 Blogs/HS820/Display_900.jpg" alt="" width="900" height="450" /></td> </tr> <tr> <td> <p style="text-align: center;">Color-coded display quickly informs the user of the operational mode.</p> </td> </tr> </tbody> </table> <p> </p> <p>The basic operation of the HS820 is easy to follow.  When the system is running, the display is green.  When feed builds up in the drop tube, the screen turns purple indicating feed has been detected.  As the feed drops away, activating the control, it goes into delay mode to prevent the feed motor from short cycling, and the display turns blue.  After the delay, the controller turns the feed motor on to fill the system, with the screen returning to green.  Should the system run longer than the preset maximum run time, the controller shuts down the system, and the display turns red.  The red display alerts the user that there is a problem with the feed delivery; empty bin, broken drop tube, etc.   The system will not run again until the user manually resets the control.  The control also comes with an alarm contact that connects to an alarm system or house controller.</p> <p> </p> <p>The color-coded display permits the user to see what mode the system is in from a greater distance.  For instance, the herdsmen easily see a red error message on the screen from the alley without entering the pen. </p> <p> </p> <p>The HS820 also includes a built-in, 24-hour time clock.  This feature allows a user to set a window of time the system can run.  For example, by setting the on time to 6 am and off time to 10 pm, the system is only operational during the day and shuts off at night.  Most competitive models require wiring an external timer to the system to add this feature.</p> <p> </p> <p>Retrofitting the HS820 to existing feed systems with mechanical or proximity switches is straightforward.   The unit is self-contained with a relay contact that connects directly to the feed system control box. </p> <p> </p> <p>For more information, click the link to <a href="https://www.hogslat.com/grower-select-infrared-feed-control">HS820</a>.</p>urn:store:1:blog:post:236https://hogslat.com/a-new-look-at-tunnel-ventilationA new look at tunnel ventilation<p>A recent development designed to improve tunnel ventilation involves substituting variable speed fans for single-speed summer fans.  These large variable speed fans utilize a different type of motor than the AC capacitor start motors normally used.  Instead, they use ECM or Electronically Commutated Motors.</p> <p> </p> <table width="491" height="42"> <tbody> <tr> <td><img src="/images/uploaded/2021 Blogs/New Tunnel/Infinity_900.jpg" alt="" width="900" height="450" /></td> </tr> <tr> <td style="text-align: center;"><span>The Infinity direct drive motor eliminates belts, pulleys, and bearings.</span><span></span></td> </tr> </tbody> </table> <p> </p> <p>While relatively new to our industry, air-conditioning manufacturers have used ECM motors for about 20 years.  ECM motors are brushless DC motors with a built-in inverter converting AC power to DC. Unlike AC motors, which become less efficient when they run at reduced speeds, an ECM motor is more efficient the slower it runs.</p> <p> </p> <p>ECM motors are only about 10% more efficient at full speed or RPMs than the standard single-speed AC motors.  For example, the Hog Slat 54-inch belt drive fan is rated at 18.6 cfm/watts, while the 54-inch Infinity fan powered with an ECM motor delivers 19.2 cfm/watts.</p> <p> </p> <p>The real energy savings come when the Infinity fan runs at less than full RPMs.  For example, two Infinity fans operating at 50% capacity produce the same CFM as a 54-inch single-speed fan but deliver it at a very efficient 36.1 cfm/watt.</p> <table width="683" height="42"> <tbody> <tr> <td><img src="/images/uploaded/2021 Blogs/New Tunnel/Infinty-vid_900 copy.jpg" alt="" width="900" height="450" /></td> </tr> <tr> <td> <p style="text-align: center;"><a href="https://youtu.be/rjeB_XNdXQc"> <strong> CLICK</strong></a> to watch a video detailing the staging of a tunnel ventilation system using Infinity fans.</p> </td> </tr> </tbody> </table> <p> </p> <p></p> <p> </p> <p>To take advantage of this efficiency, staging a tunnel system with Infinity fans is somewhat different.  Instead of powering on at full speed, the fan receives two signals from the house controller. One is an on/off signal turning the fan on, and the second is a voltage signal from 0 to 10 telling the fan how fast to run.  When the house controller needs to increase airflow instead of increasing the first fan, it instead sends two signals to a second Infinity fan to come on at 50% capacity.  This staging continues until all the Infinity fans are on operating at 50%.  When the house controller calls for the next airflow increase, all the room fans increase to 75% and then 100%.</p> <p> </p> <table width="762" height="42"> <tbody> <tr> <td><img src="/images/uploaded/2021 Blogs/New Tunnel/kWh-chart_900.jpg" alt="" width="900" height="450" /></td> </tr> <tr> <td style="text-align: center;"><span>Comparing electrical usage from a 12-month field test.</span><span></span></td> </tr> </tbody> </table> <p> </p> <p>Last year we conducted a field test of a finishing site located in eastern North Carolina with a 101-foot wide by 236-foot long building divided into two 1200-head rooms.  Each room contains a 36-inch fan and five 54-inch fans.  The 54-inch fans in one room are single-speed belt drives, while the second room’s fans are Infinity fans.  Separate electrical meters recorded power usage in each room.   The room with Infinity fans used 6755-kilowatt hours less power throughout the 12-month test period.</p> <p> </p> <p>Actual electric usage of any building will vary according to geographical location, fill dates, and target temperatures.  Along with lower electrical use, direct-drive fans will reduce maintenance costs by eliminating the replacement of pulleys, belts, and drive shafts.  Because the ECM motor generates less heat while running, we also expect it to last longer than a conventional motor.</p>urn:store:1:blog:post:235https://hogslat.com/how-will-prop-12-affect-sow-housing-2How will Prop 12 affect sow housing?<p>Set to take effect on January 1, 2022, California's Proposition 12 will prohibit the sale of pork not raised according to specific production guidelines.   This restriction includes pork produced in the state as well as production outside the state borders.</p> <p> </p> <p>While California consumes 15% of the nation’s pork, the National Pork Producers Council (NPPC) estimates only 1% of the U.S. production system currently meets Prop 12 guidelines.  While that may not impact many hog farms today, we can look at the recent history of the layer industry to understand how this may lead to drastic changes in the future.</p> <p> </p> <p>In 2008 California voters passed Prop 2, requiring confined hens "freedom of movement."  This law was later followed up in 2010 by the governor signing Assembly Bill 1437, which extended these same requirements to eggs sold instate but produced outside of the state. And in 2013, the California Department of Food and Agriculture (CDFA) issued a minimum standard requiring 116 square inches per bird. Michigan, Oregon, Maine and Washington also have laws regulating layer housing that will take effect in the near future.  In response to this regulation, cage-free egg production grew from 6% in 2008 to over 24% today.</p> <p> </p> <p>During the past decade, some production systems transitioned to group housing in response to customer welfare concerns.  They were free to choose the amount of square footage allowance along with using gestation stalls during breeding. The California statute requires 24 square feet per breeding animal and does not allow for temporary confinement of animals to exceed six hours in 24 hours and more than 24 hours total in any 30-day period. </p> <p> </p> <p>The typical farm will lose about 25 - 33% of sow capacity when moving to these increased space requirements. For a 5,000-sow farm this will mean adding a new 1,250 to1,650 head gestation building in order to maintain full utilization of their existing farrowing stalls. </p> <p> <br />There is little reason not to believe stanchion stalls will not continue to be the most popular group housing style, only requiring an increase in total square footage.  Stanchion based group housing adapts well to current U.S. production practices as it uses the same type of feed delivery system, its flexible layout accommodates remodeling and it doesn’t require farm personnel to maintain complex computer systems. The primary adjustment will be changing from gestation stalls to free access stalls during the breeding period.</p> <p> </p> <table width="748" height="42"> <tbody> <tr> <td><img src="/images/uploaded/2021 Blogs/Prop 12/Free Access Stall.jpg" alt="" width="900" height="450" /></td> </tr> <tr> <td style="text-align: center;"><span>Free Access stalls feature a sow activated rear door</span><span></span></td> </tr> </tbody> </table> <p> </p> <p>The most practical layout consists of two rows of outward-facing free access stalls with a common loafing area.  As a sow enters the free access stall, the rear door locks behind, allowing her to eat undisturbed.  She can return to the loafing area at any time by pushing against the door to release it.  It is possible to lock the animals in a stall for short durations for breeding, pregnancy checking, or individual treatment.  Free access stalls provide better working conditions for the farm staff while meeting the space requirements of Prop 12.</p> <table> <tbody> <tr> <td><img src="/images/uploaded/2021 Blogs/Prop 12/Free Access Stall Barn Layout.jpg" alt="" width="900" height="450" /></td> </tr> <tr> <td style="text-align: center;"><span> Layout showing outward facing free access stalls with a common loafing area.</span><span></span></td> </tr> </tbody> </table> <p> </p> <p>While any conversion adding additional building space and equipment requires a significant capital layout, the combination of stanchion group housing and free access stalls will be the most cost-effective alternative.</p> <p> </p> <p>Link to Free Access stall information</p> <p><a href="https://hogslat.com/global/flyers/hog-slat-free-access-stall-flyer/"><span>https://hogslat.com/global/flyers/hog-slat-free-access-stall-flyer/</span></a></p> <p> </p> <p>For more on group housing see:</p> <p><a href="https://www.hogslat.com/esf-might-not-be-the-best-choice-for-your-farm"><span>ESF might not be the best choice for your farm</span></a></p> <p> </p> <p>And download our free booklet:</p> <p><a href="https://www.hogslat.com/hog-slat-wrote-the-book-on-sow-group-housing"><span>The Stanchion Handbook, A Practical Guide for Group Housing with Stanchions</span></a></p>urn:store:1:blog:post:232https://hogslat.com/comparing-oem-and-catalog-motorsComparing OEM and catalog motors<p>Catalog or stock motors are the motors that every manufacturer produces in large volume to meet a wide range of applications.&nbsp;&nbsp; In general, these are good products built to compete in a very competitive market.</p> <p>Catalog motors used as replacements for fans and feed systems work well as long as the torque or load doesn't increase.&nbsp; As soon as a fan gets dirty or the static pressure goes up or feed density changes, the load goes up.&nbsp; The amp draw increases and the motor heats up.</p> <p>Overheating is the number one cause of motor failure.&nbsp;</p> <p>Fan and feed system manufacturers know their equipment will not operate under ideal conditions.&nbsp; They work with motor companies to create specific OEM (Original Equipment Manufacturers) motors built to match their systems' expected loads.</p> <p>Producers can decide to pay more for an OEM motor or purchase catalog motors for a lower price and hope for the best.&nbsp; There is a third option.

Along with increasing the material in the windings, GrowerSELECT motors also feature improved internal components.</p> <p>It takes more than slapping a company logo on a stock motor to compare with GrowerSELECT's quality.

We wanted to keep what has worked well for us in the past while incorporating some new features and technology to improve pig performance and reduce maintenance," said Ethan Hoffman.</span></p> <p><img src="/images/uploaded/2020 Blogs/Hoffman nursery/AquaChief_900.jpg" alt="" width="900" height="450" /></p> <p><span>Hoffman continued, "We switched from nipple drinkers to AquaChief cups to reduce water wastage.  We also mounted the cups on the back wall to prevent rusting on the gates.  To aid in getting pigs off to a fast start, we added extra water and feeder spaces."<br /><br /><img src="/images/uploaded/2020 Blogs/Hoffman nursery/Night-Light_900.jpg" alt="" width="900" height="450" /><br /></span></p> <p><span>"The controller is a big upgrade from our earlier nurseries," said   Hoffman. “The Maximus allows us to monitor the amount of feed and water consumed and check the building environment remotely.  The controller also enabled us to add night lights to each room.  The lights turn on from 9 PM – 1 AM for 15 minutes each hour to make sure pigs get up to eat and drink during the night," Hoffman added. </span></p> <p><span>One thing that didn't change much was the ventilation system.  A 14-inch pit fan runs continuously, pulling winter minimum air in through two 10-inch PVC tubes.  As additional fans stage on increasing static pressure, hallway inlets open to bring more air from the hallway.  Air enters the hallway through roll-up curtains on the outside wall.</span></p> <p><img src="/images/uploaded/2020 Blogs/Hoffman nursery/Vent_900.jpg" alt="" width="900" height="450" /></p> <p><span>"The rafters and nail plates in our original nurseries are in great shape even after 20 years of operation," said Hoffman. "We contribute a lot of that to not having any inlets or ventilation openings in the ceiling.  All the air enters through the sidewalls with no chance for leakage back into the attic."</span></p> <p><span>"A big advantage of working with Hog Slat on this project was the service.

"The positive pressure effectively reduces the amount of outside contaminants entering the building along with providing a cool environment which helps to increase semen quality during hot weather."</p> <p><img src="/images/uploaded/2020 Blogs/AI Vent/AC-Unit_900.jpg" alt="" width="900" height="450" /><br />Conditioned air enters the building at five different locations where ducts, with inline high-efficiency particulate air filters, bring in cooled air from tandem AC units. Ceiling-mounted stir fans distribute this incoming air throughout the room.</p> <p> </p> <p>"Because we are continually bringing in outside air, a single unit can only provide about a 15-degree temperature drop. Since our target temperature is 68 – 73 degrees F we need additional capacity during hot weather."</p> <p><img src="/images/uploaded/2020 Blogs/AI Vent/Exhaust-vent_900.jpg" alt="" width="900" height="450" /></p> <p> </p> <p>Two 14-inch, continuously running fans pull air from the full pit under the facility.  In addition, two mechanically-actuated 42-inch x 42-inch vent doors open and close to maintain a positive static pressure of 0.06-0.07 inches. </p> <p><img src="/images/uploaded/2020 Blogs/AI Vent/Hold_900.jpg" alt="" width="900" height="450" /></p> <p> </p> <p>The ventilation design in the load out room also helps prevent outside air from entering the facility.  A single 24-inch fan pulls air from the main room to pressurize the smaller holding area. After pressurizing the room, the operator can open the air-locked load out doors without outside air entering.  After relocking the doors, a 24-inch exhaust fan is switched on to pull air from two filtered ceiling inlets, flushing out any contaminants from the room.</p> <p> <img src="/images/uploaded/2020 Blogs/AI Vent/Coll-Area_900.jpg" alt="" width="900" height="450" /></p> <p> </p> <p>Petersen and his father, Doug, designed and fabricated the equipment for the collection area.

Also, check the filter's mesh size, particularly if you noticed a lot of wear on the internal medicator parts.  Anything larger than a 200 mesh/80-micron screen allows sand and grit to go through to the medicator potentially damaging the unit.</p> <p> </p> <p><img src="/images/uploaded/2020 Blogs/Medicator/EleMEd_900x450.jpg" alt="" width="770" height="400" /></p> <p> </p> <p>Finally, it may be time to consider a different type of medicator than the water-powered model you have used up to this point.  When volumetric pumps were introduced to the industry thirty plus years ago, they completely changed how we treated animals with medications and supplements.  But because they mix inside the unit, the combination of bad water and harsh chemicals can damage internal components no matter what type of materials are used for the springs and seals.</p> <p> </p> <p>Electric medicators receive a pulse reading from the water meter and inject chemicals directly into the water system.  No mixing occurs inside the unit, so the moving parts never come into contact with harsh chemicals or poor quality water.  Also, an electric medicator can easily interface with the house controller to record and verify treatments.  There are two common types of electrical pumps available in the livestock and poultry market.  One is a peristaltic pump where rollers compress and depress a tube creating a vacuum to inject a chemical solution into the waterline. (<a href="https://www.hogslat.com/stennicator-1-128-fixed-ratio-medicator-pump">See an example here</a>) The other is a diaphragm type where the pump head wall flexes to inject stock solutions to the water system.  (<a href="https://www.hogslat.com/e128-electric-metering-pump">See diaphragm pump here</a>). </p> <p> </p> <p>While electric medicators cost more than traditional medicators, the combination of lower maintenance, wider chemical compatibility, and the ability to connect with house controllers may fit some farms, especially those using aggressive chemicals for water treatment.</p> <p> </p> <p> </p> <p> </p> <p> </p> <p> </p>urn:store:1:blog:post:221https://hogslat.com/fall-building-maintenance-shortlistFall building maintenance shortlist<p><strong>1) Summer fans</strong></p> <p style="padding-left: 30px;">A) Clean the inside of the fan and shutters with either a broom or compressed air to remove any dust and dirt.</p> <p> </p> <p style="padding-left: 30px;">B) Seal the fan to prevent cold air from entering the building.

Most installations use the nipple's preset orifice and water pressure between 20 to 40 pounds per square inch. Operators raise or lower water pressure to regulate water flow without ever knowing the actual flow rate of the nipples. <br /><br /><img src="/images/uploaded/2020 Blogs/Water lines/Orifice_900x450.jpg" alt="" width="900" height="450" /><br /></span></p> <p><strong>Adjust the nipple orifice setting to fine-tune water delivery.</strong></p> <p><span> </span></p> <p><span>To measure a nipple's flow rate, use a quart measure, hold the nipple open and determine the water flow for one minute. Adjust the water pressure and orifice size to achieve the desired flow rate. As a rule of thumb, do not adjust the water pressure below 10 psi or above 50 psi.  </span></p> <p><span> </span></p> <p><strong><span>Think differently about consumption</span></strong><span> </span></p> <p><span>Charts typically list pigs' water requirements by their daily consumption. But when the air temperature exceeds 80 degrees F, pigs tend to consume the bulk of their needs during the first three hours of the next several mornings. </span></p> <p><span> </span></p> <p><span>A typical layout for a 1,000-head finisher would have 40 pens or 20 on each side. Each of the 20 pens would have two nipple drinkers, each with a flow rate of one quart per minute. If the pigs activate all the nipples at once, each supply line's total requirement becomes 10 gallons per minute (40 drinkers multiplied by 1 quart/min divided by 4 quarts/gallon). Anything less than a one-inch line will not supply peak water demand, causing some drinkers to have reduced water flow. Supplying the system from the middle instead of the end halves the flow rate, and then 3/4" lines would provide sufficient water flow.  </span></p> <p><span> <img src="/images/uploaded/2020 Blogs/Water lines/drinker-hoses_900x450.jpg" alt="" width="900" height="450" /><strong>Hose bib connections and small diameter medicator supply lines reduce water flow.</strong></span></p> <p><span> </span></p> <p><strong><span>Supply line size may not be the only limiting factor  </span></strong></p> <p><span>Even with the supply line sized correctly, installation errors can limit water delivery. Water meters, regulators, filters, and pressure reducers are commonly available with 3/4" connectors. Reducing a 1" or 1 1/4" PVC line with adaptors down to 3/4" fittings changes their delivery to the same as a 3/4" line. Probably the most common water restriction occurs at the medicator plumbing. Most 11 gallons per minute models used in livestock production come with a 3/4" connection reducing the water volume. Using 3/4" hose bibs and 1/2" washing machine hoses reduces the flow rate even further. </span></p> <p><span> <img src="/images/uploaded/2020 Blogs/Water lines/Dirty-line_900x450.jpg" alt="" width="900" height="450" /><strong>One-eighth inch buildup can reduce flow by 30%</strong></span></p> <p><span> </span></p> <p><strong><span>Dirty lines decrease flow</span></strong></p> <p><span>It would be fair to assume most water lines have some degree of biological buildup inside. A 1/8" deposit in a 3/4" water line reduces its capacity by 30%. In other words, this restriction cuts flow from 5.5 gallons per minute to 3.85 gallons per minute. This reduction in flow complicates situations where water flow is already marginal. Regular water line sanitation and flushing help prevent buildup inside supply lines. </span></p> <p><span> </span></p> <p><span>Managing water delivery to pigs is essential for peak performance during hot weather.

Heavy deposits of scale require a broom to dislodge the debris and then rinsing them off the pad with a low-pressure hose nozzle. The best way to deal with scale is to prevent it from forming in the first place.  Adding a descaling treatment to the water helps keep the minerals in suspension and prevents them from sticking to the pad.</p> <p> </p> <p>Nutrients in the water allow algae to grow and block the openings in the pad.  Adding algaecides to the recirculating water kills the algae and prevents it from re-establishing.  Allowing the pad to dry completely for several hours each day also stops algae growth. </p> <p> </p> <p>The most critical management practice for cool cell maintenance is to drain and replace the water often. Even with the use of chemical agents, a buildup of contaminants occurs in the trough. How often to replace the water depends on water quality and the amount of the time the system operates each day.   Once a month is an absolute minimum during periods of heavy use to flush grit and dirt from the system.</p> <p> </p> <p><img src="/images/uploaded/2020 Blogs/Static Pressure/Fan-Belts-900x450.jpg" alt="" width="900" height="450" /></p> <p> </p> <p>If the static pressure is too low, the first reaction might be to add fans to increase airflow. In many cases, especially in buildings where the airflow seemed adequate before, replacing the fan belts and pulleys will restore the proper airflow.   Slippage caused by worn belts and pulley cause fans to be less efficient and air delivery to suffer by as much as 20%.  Plan to replace all fan belts on an annual basis with the metal pulleys needing replacement about every four years.   A visual check after installing a new belt should show the belt riding high in the pulley groove.  If a new belt sinks into the groove, then the pulley should be replaced. </p> <p> </p> <p>Routine, scheduled maintenance on fans and evaporative systems is fundamental to providing pigs with adequate cooling during hot weather extremes. </p> <p> </p> <p> </p>urn:store:1:blog:post:217https://hogslat.com/rodent-baiting-strategies-for-extended-downtimeRodent baiting strategies for extended downtime<p><span>Whenever the time between groups stretches to 14 days or more producers, have a unique opportunity to reduce a site's rodent population. During normal production cycles, a large amount of feed is always available to rats and mice. Shutting a building down for an extended period eliminates this food source, with only the baits remaining. <o:p></o:p></span></p> <p><span> <o:p></o:p></span></p> <p><span>Start by removing any remaining feed. Not only the feeders, but also from the feed lines, bins, bin boots, sacks of feed in the workroom, and spilled feed on the bin pad. Remove all competing sources of food. <o:p></o:p></span></p> <p><span> <o:p></o:p></span></p> <p><span>After removing the feed, shut the buildings up and simulate the house environment as if the pigs were still there. An undisturbed building keeps rodents in place and looking to eat instead of migrating. Do not disturb the houses with a cleanout or wash down for at least seven days, if possible. By not disrupting the rodent's day-to-day activity and travel, they are more likely to find the baits and consume a lethal dose.  <o:p></o:p></span></p> <p><span> <o:p></o:p></span></p> <p><span>Place shallow trays along the interior building walls every 12-15 feet loaded with soft baits containing the active ingredient Difethialone, such as LiphaTech's FastDraw. After seven to ten days, pick up the FastDraw, rotate to soft baits with a fast-acting Bromethalin base, like Liphatech's Cannon, to kill any survivors.  <o:p></o:p></span></p> <p><span> </span></p> <p><img src="/images/uploaded/2020 Blogs/rat bait/Soft-Bait_900x450.jpg" alt="" width="900" height="450" /></p> <p><span> <o:p></o:p></span></p> <p><span>Don't forget the other areas of the buildings, including attics, control rooms, workrooms, and cool cell areas/doghouses. Also, bait other structures on the site like well houses and generator sheds. One of the advantages of using soft baits is the ease they adapt for use in hard-to-bait areas. It is simple to nail the packets to trusses or along building walls or secure them to a length of wire lowered under the slats. <o:p></o:p></span></p> <p><img src="/images/uploaded/2020 Blogs/rat bait/Exterior-Bait-Stations_900x450.jpg" alt="" width="900" height="450" /></p> <p><span> <o:p></o:p></span></p> <p><span>Make sure all bait stations on the outside perimeter of houses have fresh bait in them, and the stations are clear of debris (grass, insects, nesting material, and old bait).<o:p></o:p></span></p> <p><span> <o:p></o:p></span></p> <p><span>Continue to monitor bait stations and interior trays replacing baits as needed.

Quite often, adding one new high-capacity fan will add enough airflow to boost the wind speed to the desired level. The second choice growers often consider involves changing out the existing motor pulley to a larger size, increasing the prop speed, which in turn, raises the fan's air delivery.   <o:p></o:p></span></p> <p><span> </span></p> <p><span>While it might be tempting to do so when comparing the cost of a new fan (including installation and wiring) versus the price of just adding pulleys, here are some additional factors to consider.<o:p></o:p></span></p> <p><span> </span></p> <p><span>Engineers design fan propellers to perform at a specific blade speed or revolutions per minute (rpm), including an overage built in as a safety factor. Increasing the blade speed over the safety factor will eventually cause the prop to fail. For example, changing the motor pulley from a factory-installed AK31 (3.1-inch) to a larger AK34 (3.45-inch) size will increase the propeller speed from 545 rpm to 607 rpm. This increase amounts to 11.4%. Stepping up to AK37 or 3.55-inch size increases the tip speed to 624 rpm or an increase of 14.49%. The probable result is a premature propeller failure and a possible safety hazard.<o:p></o:p></span></p> <p><span> </span></p> <p><span>A fan engineer then selects the best motor for a particular fan by calculating the power load from the propeller. Efficient motors run close to their rated amp draw with a built-in service factor to protect the motor from short-term spikes. A motor operating at higher amperage for an extended time will generate excess heat. Overheating is the leading cause of motor failure.<o:p></o:p></span></p> <p><span> </span></p> <p><img src="/images/uploaded/2020 Blogs/Fan Pulleys/Pulley Graph _770x400.jpg" alt="" width="770" height="400" /></p> <p><span> </span></p> <p><span>The chart above illustrates the increase in amp draw as the motor pulley increases in size for a 57-inch fan. With the original 3.1-inch pulley, the motor draws 6.4 amps, which is within its operating range. Increasing the pulley to 3.2 inches also increases the amp draw to 7.8. The motor is now running continuously at its service factor, generating additional heat and shortening the motor's useful life. Increasing the pulley sizes to 3.45 or 3.55 will leave the motor continually operating in an overloaded mode. <o:p></o:p></span></p> <p><span> </span></p> <p><span>It is worth noting, the size difference from an AK31 to an AK34 pulley is barely noticeable visually but significantly changes the prop speed and the motor's amp draw. <o:p></o:p></span></p> <p><span> </span></p> <p><span>To avoid overloading the motor, it may seem logical to increase the motor size. For instance, replace a one horsepower motor with a horse and half motor. But, the new motor will still have an increased amperage draw. The increased amperage could easily exceed the capacity of the existing wiring and circuit breakers.  <o:p></o:p></span></p> <p><span> </span></p> <p><span>It will also probably cost more to operate a building with overloaded fans than one outfitted with a new fan. For example, an existing house pulls 600 feet per minute with ten fans, and adding larger pulleys increases the wind speed to 675 fpm. But doing so also changes the original fans' cfm per watt rating from 19.8 down to 15.9 cfm/watt. Those ten fans now consume 20.377 kilowatts per hour.<o:p></o:p></span></p> <p><span> </span></p> <p><span>If instead, the house had an additional fan installed, the eleven fans would consume a total of 16.67 kilowatts per hour. This reduced power usage means adding one fan compared to changing pulley sizes uses 4.21 kilowatts less per hour. Assuming an average cost of 13¢ per kilowatt-hour, this means that a grower would save $0.5473 per hour when all the fans are in operation.<o:p></o:p></span></p> <p><span> </span></p> <p><span>A producer may succeed at increasing airflow by changing pulley sizes...for a while.

The choice of chemical disinfectant used may have unforeseen negative results on the life of buildings and equipment.</p> <p> </p> <p>Sodium hypochlorite or bleach is an inexpensive and commonly used disinfectant.   While typical dilutions are not harmful to metal, high concentrations can discolor and damage stainless steel.</p> <p> </p> <p>High concentrations of quaternary ammonium compounds are corrosive to metals.  Although damage will not usually occur with normal dilution rates, the applicator should avoid direct spills on metal surfaces.</p> <p> </p> <p>Peroxgen compounds are corrosive to metals, including hot-dipped galvanized coatings.  Label directions on the most popular brand states, "Do not immerse metal objects for long periods,10 minutes is maximum contact time".  An in-house corrosion test on metal test strips showed a reduction of the galvanized coating from 4.522 mils to 3.463 mils in 24 hours.  It is crucial to rinse metal surfaces with fresh water after 10 minutes of contact time to avoid deterioration of the zinc coating.</p> <p> </p> <p>Litter treatment products containing sodium bisulfate are a popular choice for controlling ammonia buildup in poultry houses.  Sodium bisulfate is included in the class of compounds known as acid salts.  While label directions state it is safe to use with animals present, this salt will destroy galvanized coatings it comes in contact with when combined with moisture.</p> <p></p> <p><img src="/images/uploaded/2020 Blogs/Disinfectant damage/hydrated-lime_900x450.jpg" alt="" width="900" height="450" /></p> <p> </p> <p>Mixing calcium oxide with water produces a product known as hydrated lime or slaked lime used to disinfect barn surfaces.  When dry, quicklime is not excessively corrosive to galvanized steel, but when combined with water, it creates calcium hydroxide, which is corrosive to galvanized steel and aluminum. </p> <p> </p> <p>What is the most important rule for using disinfectants?  Always read and follow label directions for proper preparation and application directions.  Pay special attention to blend the correct concentrations of chemicals.  It is easy to overuse products when mixing stock solutions applied with a power washer and venturi system.</p> <p>To learn more about the characteristics of selected disinfectants, check out this <a href="http://www.cfsph.iastate.edu/Disinfection/Assets/CharacteristicsSelectedDisinfectants.pdf">chart</a> from Iowa State University</p>urn:store:1:blog:post:209https://hogslat.com/preseason-fan-maintenancePreseason fan maintenance<p>When it comes to cooling pigs and poultry, wind speed is critical.   And when it comes to moving the large volumes of air in tunnel-ventilated buildings, we rely on large energy-efficient fans.  Follow this checklist before hot weather comes next summer.</p> <p> </p> <p>1) Replace rubber fan belts annually.  Fan belts don't stretch. Instead, they wear from constant contact against the pulleys.  They ride lower in the pulley grooves as they get thinner, causing the fan blades to rotate slower.   Since the fan's air output is directly related to blade speed, it's not uncommon to see fan delivery diminished by as much as 20% because of worn belts.  See this <a href="https://www.hogslat.com/simple-guide-for-measuring-fan-v-belts">simple guide</a> for measuring the correct belt replacements.</p> <p> </p> <p><img src="/images/uploaded/2020 Blogs/Preseason fan maintenance/Link-belt_900x450.jpg" alt="" width="900" height="450" /></p> <p> </p> <p>If your fans use a link-style belt, check for cracks on the neck portion of the individual links.  The neck is the part of the link subject to the highest amount of stress as it rotates around the pulleys.  Replace the entire belt, not just the damaged link. Since every link is subject to the same amount of flexing, the rest of the links will probably continue to fail in short order.   For instructions on installing a link-style belt, click <a href="https://www.hogslat.com/power-twist-v-belt-for-fans-type-b">link belt</a> and watch the videos at the bottom of the page. </p> <p> </p> <p>2) Check the pulleys.  While you have the belts off, visually examine the pulley grooves for wear.  The grooves should have a sharp V shape.  Replace pulleys with rounded grooves.  An excellent tool for aligning new pulleys with the existing drive assembly is the <a href="https://www.hogslat.com/hog-slat-laser-fan-pulley-alignment-kit">Laser Fan Pulley Alignment Kit</a>.  Easy to use, place the laser pointer in the pulley groove, and adjust the new pulley's target piece until it lines up.  The target piece also functions as a pulley groove gauge to check existing pulleys for wear.</p> <p> </p> <p><img src="/images/uploaded/2020 Blogs/Preseason fan maintenance/Auto-tensioner_900x450.jpg" alt="Check auto tensioner for proper tension registering between the first and second marks on the body" width="900" height="450" /></p> <p> </p> <p>3) Check the automatic belt tensioner.  This device contains internal springs that push against the belt to maintain its tightness.  Work it several times to ensure the tensioner is not seized.</p> <p> </p> <p>Also, check for proper tension. The indicator bar should register between the first and second marks on the tensioner body with the belt on. To increase the amount of tension, use a 15/16 wrench to rotate the body nut counterclockwise. </p> <p> </p> <p>4) Check bearings for "wiggle."  Bearings should be firm on the shaft to prevent vibrations that cause excessive wear in the entire linkage system.</p> <p> </p> <p>5) Clean interior shutters.  Dirty fan shutters can reduce fan output by 8%.  Clean shutter vanes with a soft bristle brush or broom and keep the brush on the wall by the fans where it is handy to keep the shutters clean throughout the season.  Replace any damaged vanes or vane rods that prevent them from opening and closing smoothly.  </p> <p> </p> <p>6) Replace any cone or cone sections that have been damaged by snow, ice or strong winds.  Cones add 10% to fan performance, and missing parts decrease their effectiveness.</p> <p> </p> <p>Preseason maintenance on summer fans will ensure they are operating to their full capacity during hot weather ahead.</p>urn:store:1:blog:post:208https://hogslat.com/selection-and-maintenance-of-steel-penningSelection and maintenance of steel penning.<p>The 2020 Iowa Pork Congress hosted a seminar titled "Building Maintenance and Longevity."

A voltage reduction device, called a triac, reduces the amount of voltage to a variable speed motor, slowing the revolutions per minute, which decreases the amount of air moved.<span>  </span>Controlling motor speed by varying voltage has several limitations.</p> <p> </p> <p>1) Heat buildup.<span>   </span>Even with the voltage reduced, the motor still receives the same amount of power.<span>  </span>The extra power doesn't just disappear but instead converts to heat. The excess heat buildup limits variable speed fans to 40% of their maximum output to prevent burn out.</p> <p> </p> <p>2) Less efficient. Because of the limits on the low speed, variable-speed fans must be smaller to meet the desired lower CFM rates.<span>  </span>The smaller fans are less efficient by design, and power consumption per watt increases.</p> <p> </p> <p>3) Fixed output.

Longer motor life. VFD motors run cooler since the excessive energy typically lost using a triac is not converted to heat.</p> <p>3. Fewer fans.

Upon receiving a signal from the house controller, the motor microprocessor determines the correct speed for the desired ventilation rate. It continues to monitor the shaft RPMs and adjust the power inputs to maintain the right speed.</p> <p> </p> <p>For example, if a fan's maximum is 700 RPM, and the motor receives a 5-volt signal, it will adjust the power to 350 RPMs. If the RPMs decrease, because of higher static pressure or a headwind, more power is sent to the motor to maintain the desired fan speed.</p> <p> </p> <p><span> </span>2) Reduced maintenance. The direct-drive motor eliminates shaft bearings, pulley, and belts: no more costly and time-consuming repairs and adjustments.</p> <p> </p> <p><span> </span>3) Most efficient. At full load, the Infinity motor is 10% more efficient than conventional alternating current motors. The Infinity motor maintains its high efficiency even with lower fan speeds.</p> <p> </p> <p><span> </span>4) Extended motor life. Infinity motors operate at cooler temperatures than comparable voltage-controlled AC motors, even at slower speeds. High operating temperatures are one of the leading causes of motor failure.</p> <p> </p> <p><span> </span>5) Fewer fans. Because of the Infinity fan's ability to operate effectively at low airflow rates, minimum ventilation rates are meet without using smaller, less efficient fans.</p> <p> </p> <p>Both VFD and ECM motors offer improved control and efficiency over voltage regulated speed control.<span>  </span></p>urn:store:1:blog:post:204https://hogslat.com/troubleshooting-farm-electrical-systemsTroubleshooting farm electrical systems<p>The electric systems in livestock and poultry buildings are not maintenance-free.

(Artificial load placed on the generator verifying it's performing at full capacity. Helpful in pinpointing any weak components.)</p> <p> </p> <p> Farm management may also consider entering into an annual service contract with their generator supplier. Along with the scheduled maintenance program, a typical agreement provides for on-site emergency service calls.</p> <p> </p> <p>Every farm should have a load management plan in place to balance the generator output with the electrical loads.<span>  </span>In many cases, the generator is not sized to run the farm's electrical system at full capacity. A load management plan details which equipment should be activated when the farm is operating on emergency power. For example, the plan could call for shutting off the tunnel fans in a gestation/breeding building and lowering the curtains for ventilation. While in the farrowing house, the fans would continue to operate, but half the heat lamps would be switched off.</p> <p> </p> <p>Even with a generator sized to power the entire facility, it is prudent not to tax the system to capacity. Check the running load and if in doubt, take any unnecessary equipment offline to provide a margin of error.<span>  </span>Just assuming the generator is capable of running the entire facility is risky. It is crucial to monitor and manage an operating generator.</p> <p></p> <p>Responsible operation of a generator means monitoring the amount of available fuel. Instead of relying on a sight gauge, use a simple fuel dipstick. Make one from ¾ inch wooden dowel rod designated with 1/4, 1/2, 3/4 and FULL marks. Insert the dipstick into the tank and visually check the fuel level. Also, post the expected run time for each fuel level near the generator. The operator can then estimate how long the facility will stay powered according to the current fuel level.</p> <p> </p> <p><img src="/images/uploaded/Blog/Generator/Gen-Tank_900x450.jpg" alt="" width="900" height="450" /></p> <p>After generator startup, the farm manager should<span>  </span>verify the amount of fuel in the supply tank.</p> <p> </p> <p><span> </span></p> <p>After generator startup, the farm manager should verify the amount of fuel in the supply tank. Don't assume there is adequate fuel and leave the farm, only to find out later the generator ran out of fuel several hours later. The operator should continue to check the fuel level noting any variations from the estimated run times. Powering the farm during weather extremes, such as operating large fans in the summer or heating systems in the winter, can easily cause the generator to use more fuel than estimated.</p> <p> </p> <p>Remember a facility running on standby power has no fallback position.<span>  </span>Performing routine generator maintenance and detailing an operating plan helps to ensure the health and well being of our animals during power outages.</p>urn:store:1:blog:post:196https://hogslat.com/ventilation-notes-2-propsVent Notes #2 - Props<p>Learn how prop design affects air delivery and efficiency of ventilation fans.</p> <p></p> <p>First, a few prop basics.</p> <p> </p> <p><img src="/images/uploaded/Blog/Props/Prop Speed Drawing 900x450.jpg" alt="" width="900" height="450" /></p> <p> </p> <p>Air movement across a fan prop is not equal.<span>  </span>A 54-inch fan turning at 560 revolutions per minute will have a tip speed of almost 132-feet/ second while at the hub travels it at only 24-feet/second.<span>  </span>Because of this speed difference, nearly 75% of the air volume comes from the outside 25% of a prop with flat blades.</p> <p><img src="/images/uploaded/Blog/Props/Fan Blade Drawing 900x450.jpg" alt="" width="900" height="450" /> </p> <p>To produce a more efficient prop, fan designers change the profile of the individual blades.<span>  </span>The fast-moving tip section is flatter with the blade making a gradual, increasing twist towards the prop hub.<span>  </span>Many designs also increase the size of the blade in the midsection while removing material in the tip and center sections.<span>  </span>The result of this manipulation evens out the amount of air moved across the blade. <span> </span></p> <p> </p> <p>Successful fan props can be built from many different materials such as cast aluminum, plastic, composite fiberglass and stainless or galvanized steel.<span>  </span>Cast aluminum and composite props provide the best combination of durability and performance for smaller diameter fans.</p> <p><img src="/images/uploaded/Blog/Props/Fan-end-wall_900x450.jpg" alt="" width="900" height="450" /></p> <p></p> <p><span> </span></p> <p>Most of a facility's electrical consumption occurs when running large fans for cooling making energy efficiency a primary design factor for fans 48 inches and larger.<span>  </span>Steel props match or exceed the performance values of more expensive prop materials like cast aluminum and injection molded plastics.<span>  </span>Bottom line, producers can buy very efficient steel prop fans for a much lower initial installed cost when constructing new buildings or remodeling.<span>  </span></p> <p> </p> <p>Here are a couple of final thoughts on fan props.<span>  </span>Even the best-designed and manufactured prop cannot perform to its full potential when dirty.<span>  </span>An1/8-inch of dust can reduce fan delivery by up to 10%.<span>  </span>Also, when replacing a fan prop, be sure to select a prop designed specifically for that particular fan.<span>   </span>Just because the bore and prop diameter match the existing fan doesn't mean the performance will be equal. <span>  </span></p> <p></p> <p></p> <p></p>urn:store:1:blog:post:194https://hogslat.com/fogger-coolingFogger cooling<p></p> <p>Austin Baker, Hog Slat Ventilation Director.</p> <p> </p> <p>We commonly think of cool cell systems when we think of evaporative cooling in hog facilities.<span>  </span>However, fogger systems also cool pigs by evaporation; understanding how will help you manage these systems more effectively.</p> <p> </p> <p>As incoming air passes through cool cell pads, the energy used to evaporate the water lowers the air temperature.<span>  </span>The resulting air cools the pigs indirectly.<span>  </span></p> <p> </p> <p>Fogger systems wet the skin of the pigs, as the water evaporates off their skin the pigs are directly cooled.<span>  </span>The key to using a fogger system correctly is to set up this cycle of wetting and drying the pigs.</p> <p><img src="/images/uploaded/Blog/Fogger Cooling/Fogger-control_900x450.jpg" alt="" width="900" height="450" /></p> <p></p> <p> </p> <p>First set the on time to thoroughly wet the pen area, usually two to four minutes.<span>  </span>Next, clock the time it takes for the pen and pigs to dry off completely.<span>  </span>This period becomes the off time on the controller.

production site into a rural showcase, the appearance of our farms goes a long way to building acceptance by non-farming neighbors.</p> <p> </p> <p>Mow the grass.  While nobody expects a suburban worthy lawn on a farm, regular mowing and weed trimming gives every site a business-like appearance.  Adding a gravel border around the buildings gives them a clean look and makes trimming easier.</p> <p> </p> <p>Maintain the driveway.   Driveways full of ruts and potholes create a bad impression on traffic driving past the farm.  Regular blading and filling the low spots goes a long way to improving the site entrances.  Pay particular attention to the borders and cut back any vegetation creeping into the roadway. </p> <p> </p> <p>Plant border trees.  The old axiom "Out of sight is out of mind" is especially true in this case.  Neighbors will probably have less reason to smell a site they can't see.  While every region of the country will vary according to the best varieties to plant, fast-growing trees such as poplar, willows, and cedars quickly create a "green screen."   Consider turning the border into a multi-species windbreak to provide habit for wildlife.  It's harder to consider a site a nuisance with pheasants, quail, and deer taking shelter in the borders.  Also "green screens" may provide some level of odor and dust control.</p> <p> </p> <p>Cover up <span>mortalities. </span>The average death loss in a finishing house is between two and three percent.  It can be a little shocking to a neighbor unfamiliar with the scale of a typical finishing operation to see several large hogs lying on the ground.   While most dead boxes have a fence around them, it is not uncommon to drive down the road and see gates left open and visible carcass. </p> <p> </p> <p>We all have hectic schedules, and it is easy to put off grounds maintenance for tasks that seem more important.  But taking time to do basic upkeep may help prevent bigger headaches with

water doesn't leave the mixture; it reacts with it and becomes part of the final form of the concrete.</p> <p> </p> <p><img src="/images/uploaded/Blog/Slat U-103.Curing/concrete-cure-diagram_900x450.jpg" alt="concrete curing diagram" width="900" height="450" /></p> <p> </p> <p>Instead of drying, concrete instead cures.  The water added to the mixture reacts or hydrates with the cement and aggregates to form the bond that creates concrete.  Concrete does not need to dry out to harden as is commonly thought; in fact, the mixture needs to have moisture present to set correctly.</p> <p> </p> <p>The most common and low-tech method to cure precast concrete is to allow it to "set up” at the existing ambient temperature for a period longer than 28 days.    Problems with this process occur when the temperatures are too low, or it is necessary to ship product before 28 days.</p> <p><img src="/images/uploaded/Blog/Slat U-103.Curing/Steam-tent-image_900x450.jpg" alt="steam tent" width="900" height="450" /></p> <p> </p> <p>Accelerated curing using steam produces a more consistent quality of precast concrete.   The slats are stacked and covered with a tent with steam pumped into the enclosures.    The increased heat of the steam speeds up the cure time and provides additional moisture so the water inside the concrete is not lost and can complete the hydration process.   The strength of steam heat concrete after three days will equal or exceed the 28-day strength of normally cured concrete.</p> <p> </p> <p>This method of curing slats provides several advantages. </p> <p> </p> <p>First, the curing process isn't affected by the weather.   Cold, heat, wet, and dry conditions don't change the final strength of the slats and beams. </p> <p> </p> <p>Second, faster cure time permits slats to be shipped to a job site without a standard 28-day cure time.  This reduced time is especially critical during the height of the building season when slats might be in short supply.   Slat manufacturers using an air cure method might be tempted to cut corners and ship slats before they are ready.</p> <p> </p> <p>The proper curing of concrete slats determines its quality and projected life cycle in production facilities.  Controlled curing with steam heat provides all the elements needed for manufacturing consistently high-quality products.  </p>urn:store:1:blog:post:186https://hogslat.com/slat-university-102-reinforcing-steelSlat U.102 -Reinforcing Steel<h1></h1> <p></p> <p><strong>Adding steel to precast concrete changes its properties.</strong></p> <p>We measure the strength of cured concrete by testing the pounds force per square inch or psi.   The psi rating

strength of concrete is excellent, it lacks tensile strength or the ability to resist flexing.  In other words concrete is brittle.

These opposing properties are why the two materials are used together when producing concrete products.  Embedding reinforcing steel in the concrete increases its ability to resist failure from tensile stress.</p> <p> </p> <p>Concrete slats are cast with steel bars placed at the top and bottom of the slats.  The top bars protect the slat from cracking while the slat is being transported and set in place.  After the slat is in place, the lower bar keeps the slat from cracking on the bottom.</p> <p><strong><img src="/images/uploaded/Blog/Slat U_ Reinforcing Steel/WWR_950x450.jpg" alt="WWR" width="950" height="450" /></strong></p> <p></p> <p><strong>Welded Wire Mats have several advantages over rebar for slat production</strong></p> <p> </p> <p>While rebar is the most common type of reinforcing steel used in poured-in-place concrete, welded wire reinforcement mats offer some distinct advantages when used in the production of concrete slats.   Fabrication of WWR mats consists of welding steel rods into large sheets specific to each slat mold.</p> <p> </p> <p>1) WWR mats are made from high tensile 80,000-psi steel wire formed by special equipment to the proper diameter and straightened.  In comparison, rebar has a lower 60,000-psi rating.</p> <p> </p> <p>2) By welding them into a mat, the rods do not move when concrete is placed, ensuring each bar is in its proper position.</p> <p> </p> <p>3) Automated equipment located in a controlled environment prefabricates the WWR mats lowering the risk of improper welds that can affect the strength of the steel.</p> <p> </p> <p>In general, using Welded Wire Reinforcement mats in the manufacturing of precast concrete slats yields a much more consistent product than production using individually placed rebar. </p> <p> </p>urn:store:1:blog:post:185https://hogslat.com/slat-u-101waterSlat U.101-Water<p><strong>Slat University is a series of articles providing useful information on manufacturing, handling and maintaining concrete slats.</strong></p> <p><strong><span>Water: Most crucial component in a precast concrete mix.</span></strong></p> <p><strong> </strong></p> <p>Anybody who has ever poured concrete is familiar with the adage "the less water you use, the stronger the concrete will be." </p> <p> </p> <p>Here's why.</p> <p><img src="/images/uploaded/Blog/Slat U_101.Water/Water-Cement-Ratio-Image-900x450.jpg" alt="water_cement" width="900" height="450" /><strong>Excess water evaporates leaving behind large voids weakening the final product.</strong></p> <p>Water added to the dry ingredients begins a chemical reaction with the cement powder known as hydration, which bonds the aggregates together, creating the synthetic rock known as concrete. Any additional water added, beyond that needed for hydration, only creates larger spaces between the aggregates in the mix. These voids cause the concrete to be weaker and more porous.</p> <p> <img src="/images/uploaded/Blog/Slat U_101.Water/slump-cones_900x450.jpg" alt="slump cones" width="900" height="450" /></p> <p></p> <p><strong> Every additional inch of slump decreases the final strength by approximately 500 psi.</strong></p> <p> </p> <p>Concrete formulated with a minimal amount of water is known as dry-cast concrete.  To put this is in more familiar terms, dry- cast concrete exhibits a slump of less than a 1/4-inch.   Ready-mix concrete is typically formulated to have a four-inch slump. As a general rule, every additional inch of slump decreases strength by approximately 500 pounds per square inch. So for example, if a dry cast mix is designed to be 6000 psi, adding water to make it a four-inch slump could reduce the strength of the final product by as much as 2000 psi.</p> <p> </p> <p>Also, a dry cast product is also denser with fewer voids. As the excess water evaporates from the concrete with a higher water-cement ratio, microscopic pores are left behind.  These pores allow acids from hog waste and feed ingredients to migrate into the concrete, causing faster deterioration of the slat.</p> <p> </p> <p>If less water makes the best concrete why would any slat manufacturer ever add extra water?</p> <p> </p> <p><img src="/images/uploaded/Blog/Slat U_101.Water/rotoscreed_900x450.jpg" alt="rotoscreen" width="900" height="450" /> </p> <p>P<strong>owerful rotoscreeds trowel dry cast concrete.</strong></p> <p> </p> <p>Dry cast concrete is very difficult to handle without mechanized equipment.  Many manufacturers lack the equipment and know-how needed to place and finish dry cast mixes properly.  Water is added to the concrete mix so it flows into the molds and can be troweled.  While this may lead to manufacturing slats with a smoother physical appearance, the finished product will not be as durable or long-lasting as a dry cast slat.</p> <p> </p> <p>Also, some manufacturers may not have the technology to batch dry cast formulations consistently. To properly make dry cast concrete it is necessary to use state of the art batching equipment that measures the amount of moisture in the sand and aggregates and adjusts the amounts of these ingredients as well as the added water. These adjustments ensure that the final mix is always the same and doesn't vary during wet or dry weather. </p> <p> </p>urn:store:1:blog:post:184https://hogslat.com/western-building-concepts-adapted-by-russian-production-systemWestern building concepts adapted by Russian production system<p><strong>Cherkizovo Group discusses factors influencing their choice of equipment for their most recent building project.   </strong></p> <p> </p> <p>The following article contains excerpts from an interview with Brad Heron, Executive Manager of Pig Production for the Cherkizovo Group.  Cherkizovo is one of Russia’s largest pork producers. Joining Brad for this interview was production manager, Alexander Busov. Ivan Svinarev from Donskoy State Agrarian University conducted the interview. </p> <p> </p> <p><img src="/images/uploaded/Blog/Cherkizovo Group/Che-Interview_950x450.jpg" alt="Che interview" width="950" height="450" /></p> <p> </p> <p><em>Ivan:  Having experience in working with different building companies, which factors could you point out that influenced your choice of facility design?</em></p> <p> </p> <p>Brad:     Well, chimney ventilation was the most common type of system in Russia.  Based on our experience we wanted to make changes and go with a more western type of tunnel ventilation.  We felt that this design of ventilation would be more productive for us. We had some experience with Hog Slat in America. In addition, they had a good operation in Russia, had already invested in their supply chain and their equipment was readily available. As we began the operation and did the expansion for the sow barns and finishing sites, we felt it was an obvious choice.</p> <p> </p> <p><em>Ivan: This cooperation can be divided into two big components: the equipment itself and production practice. Do I understand it right that the production practices in this project are Cherkizovo's ideas, not Hog Slat’s? Or is this a combination of both companies?</em></p> <p> </p> <p>Brad: When I came here the guys had already started the relationship with Hog Slat.  Our first order of business was to standardize all the operating procedures based on the best practices from throughout the world. In some cases, that information came from Spain and sometimes from North America.</p> <p> </p> <p>We wanted to be in a position that within 3 to 5 years we could start to benchmark ourselves against the world.  Our owners wanted to be the best, not only in Russia but also in the world. We felt like any new construction, especially Wean to Finish buildings, needed to be the tunnel ventilated. </p> <p> <img src="/images/uploaded/Blog/Cherkizovo Group/Che-farrowing_950x450.jpg" alt="Che-farrowing" width="950" height="450" /></p> <p> </p> <p>Some of our initial challenges began when we started to increase the productivity in the sow barns as the original buildings were only designed to handle 2800 pigs a week.  We increased productivity and pretty soon we were weaning 3100 pigs with a goal of 3800 to 4200 pigs a week. These original models no longer fit.</p> <p> </p> <p>What happens when you have a sow barn that outperforms the size of the nursery and finisher?  You have to build more nurseries and finishers...or you can build W/F buildings and gain some flexibility. </p> <p> </p> <p>We knew from a cost of production standpoint, W/ F unit under normal stocking was going to produce a cheaper pig going through this system.  It’s also more biosecure than the standard production model of nurseries and finishers because you have one less movement.</p> <p> </p> <p>Getting people to understand the advantages of W/F was a bit of a challenge.  The traditional production model in Russia is separate sow barns, nurseries, and finishers, three-step movement. </p> <p> </p> <p>Every week we wean around 45-50,000 pigs, which go to the nurseries and then we have to move them from the nurseries to the finishing buildings.  Saving the labor used in moving pigs this extra step is one of the reasons W/F units are less expensive to operate.   Also in the old system pigs finished in 168 days, in the W/F buildings they finish in 164 days.   Same weight but when we move the animals, we lose the efficiency.</p> <p> </p> <p>So today we have already built 16 W/F sites here, we have three, possibly a fourth one planned for the next year. We built a new sow barn that requires eight W/F buildings. So we constructed extra W/F sites to solve this problem. We have to go somewhere with these extra 1000 to 1400 pigs a week and so they are going to W/F units.</p> <p> </p> <p><em>Ivan:  In this farm, you use individual gestation stalls. What is your personal opinion as a specialist to pen gestation compared to individual stalls?  Do you plan to have pen gestation in Russia?</em></p> <p> </p> <p><img src="/images/uploaded/Blog/Cherkizovo Group/Che-Gest_950x450.jpg" alt="Che-Gestation" width="950" height="450" /></p> <p> </p> <p>Brad:  Obviously if we want to export to the EU in the future than we will consider that option. But if you get an honest answer from anybody, your animals are going to perform better in a sow barn with individual stalls, as the animals are easier to manage.  We do have some pen-gestated farms, and those will typically have 2-3 % lower farrowing rate.</p> <p> </p> <p><em>Ivan: For one of the key aspects in your choice of equipment you name the use of the tunnel ventilation system. The opponents of this system say that it was created for poultry and pigs don't have feathers and therefore feel discomfort. In Lipetsk region (western Russia), the experience of your company proves that there is no need for pigs to have feathers. So are you happy with the temperature range? And are there are any problems using the system during summer or winter period?</em></p> <p> </p> <p>Brad:  Tunnel ventilated farms with low ceilings are going to be better year around. In summer heat we can compare standard chimney ventilated barns with the tunnel ventilated W/F buildings.   Lots of times when you build those big chimney style barns you are kind of replicating outdoor ventilation with uneven airflow and varying temperature distribution. But with powered tunnel systems, we control the airflow and temperature much better and can raise the animals more consistently.</p> <p> </p> <p>Before we started using the tunnel ventilation we had the standard chimney system.   Alexander is responsible for commercial part, and he can comment on this.</p> <p> </p> <p>Alexander:  In the tunnel barns we have comfortable conditions no matter what time of the year.   With the same genetics and feed, we get better production figures from the tunnel ventilated farms.  Also, the old style of buildings had 12m ceilings with steam heat...it costs much less to heat the tunnel buildings with their lower ceilings.  We don’t see any minuses yet.</p> <p> </p> <p><em>Ivan - What is the main difference between a similar project in Russia and the US?</em></p> <p> </p> <p>Brad:  Sow farms are similar, around six to eight thousand sows. There are a couple of things that are different when building in Russia.   To provide protection from swine fever, we have to build a security post, disinfection barriers, and large fences around the buildings.</p> <p> </p> <p>In the US you tend to see smaller finishing sites with enough land around them to spread the manure. But for us, because of the lack of utilities and roads along with additional fixed costs to protect against African swine fever – our finishing sites are much bigger. We'll put all eight of the finishing barns for this sow farm on one location instead of eight individual sites like in the US. However, once you are inside the building, everything looks the same.</p> <p><em> </em></p> <p><em>Ivan: What do you think the key possibilities are for a further increase in productivity along decreases production costs in Russia?</em></p> <p> </p> <p>Brad: This particular sow farm is producing the lowest cost wean pig around.  For me, increases in production come when you allow the animals to maximize their genetic potential.  For that to happen, you need good genetics, good health, sound production practices, and well-designed facilities especially the ventilation.</p> <p> </p> <p>We have other sow farms that are the build on the old production style. The new farms always out produce them because they are better ventilated and easier to work in.</p> <p> </p> <p>I believe that Russia can be the leader concerning KPIs if we can figure out how to get rid of African swine fever. Russia has everything that needs to be a leader in agriculture including an agriculture culture.

Most whole house computer style controllers are capable of sending a 0 to 10-volt signal to the VFD control.  Older style controllers with on-off signals can also be used with a slightly different method.  The VFD controller features a manual speed control knob.  The operator can set the minimum ventilation, and the ventilation control can override the VFD control and run the fan at high if the building temperature increases.   As the building cools down, the control shuts off and the fan returns to the minimum rate set on the VFD control. </p> <p></p> <p><strong>By Austin Baker, Ventilation Director for Hog Slat Inc.  You can contact Austin at <a href="mailto:jabaker@hogslat.com">jabaker@hogslat.com</a> </strong></p>urn:store:1:blog:post:182https://hogslat.com/selling-a-building-four-things-you-should-knowSelling a building?

Firms regularly performing appraisals of livestock buildings will give you the most accurate evaluation.</p> <p> </p> <p><strong>2) Make a good first impression...and that starts with the realtor.   </strong></p> <p> </p> <p>"The first thing a potential buyer sees is the pictures I take during the initial site visit,” says Dale Kenne, a realtor with Agri-Management Services located in Marion, Iowa, "No one expects a manicured yard and gravel borders but at least the grass should be mowed, and the trash picked up.  I recently visited a finishing building that had been remodeled several years earlier and still had the old equipment laying around with weeds growing through it.  It was hard to take a picture without some discarded equipment showing up in the background."</p> <p><strong> </strong></p> <p><strong>3) What about remodeling...how do you get your money back?  </strong></p> <p> </p> <p>"We generally feel the building should be capable of functioning with its existing equipment," Dale explained.  "Even if the feeders are needing replacement, and the ventilation system an upgrade it doesn't make much sense for the seller to do the remodeling. In most cases, the new owner will probably need to make those changes based on the requirements of their chosen integrator."</p> <p><img src="/images/uploaded/Blog/Sell Building/Slat-repair_900x450.jpg" alt="Slat repair" width="900" height="450" /></p> <p></p> <p> </p> <p>"The existing equipment doesn't have to be new, but it should be in good working order, Kenne says "Patch any badly worn slat areas around feeders, and waterers with <a href="https://www.hogslat.com/con-korite-xtra-mortar-kit">Con-Korite™</a> and replace any severely damaged slats. Treat and cover any rust spots on the ceiling with a repair product like <a href="https://www.hogslat.com/vanberg-coatings-wmc100-metal-repair-kit">WMC-100</a>.   Tighten the legs on the penning and replace any missing gate rods and latches.   Replace curtains with holes or tears, repair the curtain ropes and rehang missing curtain pockets.  Doors, especially those on the exterior, should fit tight and have any missing knobs replaced."</p> <p> </p> <p><img src="/images/uploaded/Blog/Sell Building/curtain-install_900x450.jpg" alt="Curtain-Repair" width="900" height="450" /> </p> <p> </p> <p><strong>4) Little things make a difference... and they aren't expensive.  </strong></p> <p> </p> <p>"Getting a building ready to sell usually doesn't cost a lot of money," Kenne says. "Some simple things include replacing the burned-out light bulbs, knocking the cobwebs down and washing the alleyways.   You wouldn't believe the number of buildings I go in and see missing fan shutters and electric covers, ceiling inlets hanging open without counterweights, etc.  In the office area, the showers and restrooms should be clean enough your mother would be OK using them!"</p> <p> </p> <p> </p> <p><strong>Dale Kenne can be contacted at dale@agri-management.com</strong></p>urn:store:1:blog:post:179https://hogslat.com/do-we-really-need-pit-ventilationDo we really need pit ventilation?<p></p> <p>Pit fans are commonly used on buildings with deep manure storage to reduce the amount of gases and odors reaching pig level.  Routine maintenance of the pit fans can be difficult because of their location.</p> <p> </p> <p>Limited access to the shutters and hood discourages frequent cleaning.  Blowing snow can pile up on ground level fans.  Gaps in pit lids and transitions short-circuit air flow instead of pulling it from the building space.</p> <p> </p> <p>Winter exhaust fans located higher on the building walls are much easier to maintain than pit fans.  It is easier to access the shutters for cleaning, they are not affected by snow buildup and wall mounting eliminates air short-circuiting.</p> <p> </p> <p>To evaluate the differences between pit and wall ventilation a simple field test was set up in the fall of 2017 in matching 1,000 head finishing rooms measuring 40'x 200'.  Each room contained four 18-inch pit fans sized for minimum winter ventilation and a 36-inch fan located in the end wall for transitional ventilation.</p> <p> <img src="/images/uploaded/Blog/No Pit Vent/Pit Ventilation diagram_900x450.jpg" alt="" width="900" height="450" /></p> <p>The pit fans in one room were shut off and covered with plastic sheeting sealing them against air leaks.  In this room, the 36-inch variable speed fan provided winter ventilation.  The second room continued to operate with four 18-inch pit fans.  </p> <p> </p> <p>Ammonia and hydrogen sulfide levels were sampled using a handheld multi-gas detector with a tube sensor.  Samples were taken from nine locations in the room at slat level and at one, two and three feet below the slats.  The hydrogen sulfide levels in each room were so low that they were undetectable.    The only level of ammonia exceeding the maximum recommended allowance of 25 ppm occurred along the outside wall of the pit ventilated room.  The highest ammonia level (14.7 ppm) in the wall fan ventilated room was taken at the fan end.  The pit was not being agitated or pumped when the samples were taken.   Higher ventilation rates are required when agitating or pumping a pit because of the elevated gas levels.</p> <p> </p> <p> </p> <p>We are not representing this information as a controlled experiment with specific parameters.  This data only represents a short window of time on one particular day.  It was merely a quick test to see if the conditions in the barn without pit fans would deteriorate to the point were pig performance might suffer.   Based on the results of this test the operator discontinued using the pit fans on the rest of the farm and relied on the wall fans to ventilate the facility throughout the winter. </p> <p> </p> <p><img src="/images/uploaded/Blog/No Pit Vent/pit-fan-closed_900x450.jpg" alt="" width="900" height="450" /></p> <p> </p> <p>Several other farms in the area are in the process of remodeling existing buildings by removing the pits fans and installing wall fans for minimum ventilation.  Current plans call for continuously monitoring gas levels on these farms during winter and gathering closeouts as the pigs are sold to determine any variation in growth or feed conversion.  Look for additional information as it becomes available.</p> <p><img src="/images/uploaded/Blog/No Pit Vent/sidewall-fans_900x450.jpg" alt="" width="900" height="450" /></p>urn:store:1:blog:post:180https://hogslat.com/winter-ventilation-for-homestead-productionWinter Ventilation for Homestead Production<p>Most small-scale producers utilize natural ventilation during warm weather.  As the weather cools, regulating the environment inside livestock and poultry buildings becomes more difficult with manually operated vent doors. Adding a small ventilation fan(s) simplifies the task of maintaining a healthy environment for the animals. </p> <p> </p> <p>The first step is to determine the minimum and mild winter rates for the amount of the animals housed.  Table 1 displays a chart with recommended ventilation rates taken from an older university manual. </p> <p><img src="/images/uploaded/Blog/Farmstead vent/Table-1_900.jpg" alt="Table 1" width="900" height="446" /> </p> <p>Minimum rates are the recommended ventilation in cfm (cubic feet per minute) needed to control moisture and prevent condensation from forming on interior surfaces.  The additional mild winter airflow stops rising temperatures inside the building as the outside temperature increases.</p> <p> </p> <p>For our example, we'll use a 24' x 30' farrowing house with ten crates.</p> <p> </p> <p>10 sows/litters  x  20 cfm = 200 cfm   minimum rate</p> <p>10 sows/litters  x  80 cfm = 800 cfm   mild winter rate</p> <p> </p> <p>As a fan operates, it creates a static pressure difference between the inside and outside of the building measured in water column inches.  Pick an exhausted fan for this application according to its stated cfm deliveries at .05" static pressure.</p> <p> </p> <p>From the list of fans shown in Table 2, the 12" fan is rated at 880 cfms.   This cfm rating matches up closely with the mild winter rate in our example.   We have two options that will enable us to reduce the cfm delivery down to the minimum rate of 200 cfm.</p> <p><img src="/images/uploaded/Blog/Farmstead vent/Table-2_900.jpg" alt="Table 2" width="900" height="551" /></p> <p> </p> <p>We can use an inexpensive variable speed controller to slow the speed of the fan. (see  variable speed control #NE105F)  But be aware that a reduction in fan speed does not directly mean the same reduction in cfms.  In other words, reducing the fan speed by 50% does not reduce air delivery by 50%.    Turning a fan down too slow can also cause the motor to overheat. </p> <p> </p> <p>A more accurate method of reducing the amount of air exhausted is using a 5-minute cycle timer.  In the example above we would set the on cycle for one minute and off cycle for four minutes.</p> <p> </p> <p>20 cfm x 10 sows = 200 cfm</p> <p>200 cfm/ 880 fan cfm = 0.227 x 300 sec (Total Cycle Time of 5 min timer) = 68 sec ON or 1 minute</p> <p> </p> <p>The additional advantage of using a timer is it allows more flexibility for changing animal density.  For instance, if our example farrowing barn was half full we could reduce the <g class="gr_ gr_71 gr-alert gr_gramm gr_inline_cards gr_run_anim Grammar replaceWithoutSep" id="71" data-gr-id="71">on</g> cycle to one minute.  If we chose to wean the pigs in the crates and leave them there until they weigh 40 lbs., we would be able to increase the on time to two minutes.</p> <p> </p> <p>100 pigs x 3 cfm = 300 cfms</p> <p>300 cfm / 880 cfm = 0.34 x 300 sec (Total Timer Cycle of 5 min. timer) = 102 sec ON or 2 minutes</p> <p> </p> <p> </p> <p>Either the speed control or timer can be wired in parallel with a single stage thermostat to override the low setting. As the temperature rises inside the building, the thermostat takes over and runs the fan at full speed.  If the inside temperature goes down with the fan running on high, the thermostat drops out, the timer takes over, and the building returns to minimum ventilation.</p> <p> </p> <p>Operating the minimum ventilation during cold weather will mean adding supplemental heat to maintain a comfortable temperature for the animals.  Turning the fan down to prevent the heater from running will create damp, smelly air inside the barn.   Table 3 lists the likely supplemental heat requirements per animal.  These rates assume adequate insulation in the walls and ceiling and minimum to no air leaks.</p> <p><img src="/images/uploaded/Blog/Farmstead vent/Table-3_900.jpg" alt="Table 3" width="900" height="434" /></p> <p></p> <p> </p> <p>Using our example barn again</p> <p> </p> <p>10 sows/litters x 3000 Btu = 30,000 Btu heater</p> <p> or</p> <p>100 nursery pigs x 350 = 35,000 Btu heater.</p> <p> </p> <p>You will also need to provide air intakes matched to the total ventilation capacity of the fans.  A simple gravity activated sidewall inlet (see #HS1200) is the best choice for most situations.  Inexpensive and easy to install, this simple plastic inlet automatically opens allowing airflow when the fan(s) operate.  When the timer shuts the fan off, the plastic louver closes.  </p> <p> </p> <p>Inlets installed in an outside wall require a hood to protect strong winds from forcing the louver open.   See Inlet Hood diagram. Inlets are typically located opposite the fan(s) to pull air across the building.</p> <p><img src="/images/uploaded/Blog/Farmstead vent/weatherhood_900.jpg" alt="Inlet hood drawing" width="900" height="689" /></p> <p> </p> <p>Each inlet is rated at 430 cfm.  To determine the number of inlets needed, divide the total cfm by 430.  Using our example</p> <p> </p> <p>880 cfm/ 430 = 2.04 or 2 inlets needed. </p> <p> </p> <p>We provided this short article as a guide to adding wintertime ventilation to an existing building.  Your individual building will vary by location, the condition of the structure and other factors.  For a detailed calculation of the ventilation equipment needed for a particular building, please contact us at web.info@hogslat.com.</p> <p> </p>urn:store:1:blog:post:177https://hogslat.com/direct-cooling-with-stir-fans-and-sprinklersDirect cooling with stir fans and sprinklers.<p><strong> </strong></p> <p><strong>By Austin Baker, Ventilation Director, Hog Slat Inc. </strong></p> <p></p> <p>The summer performance of curtain-sided, naturally ventilated buildings can be improved by utilizing a combination of stir fans and a sprinkler system to reduce animal heat stress.</p> <p> </p> <p>Pigs feel a cooling effect as high-velocity air from the stir fans moves across their body.  By wetting the pig's skin, we increase the cooling effect as the air evaporates the water removing heat from the animal.</p> <p> </p> <p>For direct cooling to work efficiently, the pig's skin should be thoroughly wetted and then allowed to dry completely.  The wetting and drying cycle is a critical part of the process.  If the pigs are continuously wet, the humidity rises which in turn reduces the amount of cooling by evaporation.</p> <p> </p> <p><img src="/images/uploaded/Blog/Stir fan cooling/Sprinkler-nozzle_900.jpg" alt="fogger nozzles" width="900" height="450" /></p> <p> </p> <p>Choose <a href="https://www.hogslat.com/34-fogger-with-tee">nozzles</a> that produce coarse droplets vs. a fine mist.  Large drops fall quickly thoroughly wetting the pigs while a fine mist hangs in the air increasing humidity.  The control system should include an adjustable timer enabling the system to operate for two to four minutes every 15 to 30 minutes after reaching the temperature set point. </p> <p> </p> <p>For optimum cooling, strive for an air velocity of 300 fpm at pig level.  The effective thrust of a fan is 2X (in feet) of its diameter.</p> <p> </p> <p>For example:</p> <p>18" fan - 36'</p> <p>20" fan - 40'</p> <p>24" fan - 48'</p> <p> </p> <p><img src="/images/uploaded/Blog/Stir fan cooling/Stir-fan-layout_900.jpg" alt="" width="900" height="450" /></p> <p> </p> <p>We show typical layouts for 40' x 200' finishing building with both a racetrack and cross-staggered patterns.  Angle the fans in the racetrack pattern at about 20° towards the middle.</p> <p> </p> <p>Stir fans also do an effective job circulating stratified air during colder weather.   Low winter ventilation rates decrease air movement in the building creating a 5 to 10-degree temperature difference from floor to ceiling.  By slowing the stir fans down to a minimum speed, a gentle circulation pattern mixes the layered air.  Forcing the warmer air to the floor reduces heating costs and results in drier slats.   Tilt the fans towards the ceiling and monitor airflow at floor level being aware that movement greater than 50 fpm can feel like a draft to the pigs. </p>urn:store:1:blog:post:178https://hogslat.com/vfd-offers-improved-control-of-variable-speed-fansVFD offers improved control of variable speed fans<p>Most power ventilated livestock facilities rely on some method of control input to reduce the amount of air exhausted during colder weather.  The farm operator calculates the number of animals and their weight to determine minimum ventilation rates expressed as cubic feet per minute or cfm.</p> <p> </p> <p>The volume of air produced by a fan is directly related to its rpm or revolutions per minute.  Reducing the operating speed also reduces the airflow the fan generates. The most common method of speed regulation utilizes a device called a triac to regulate the amount of voltage to the fan motor. </p> <p> </p> <p>Although voltage regulation allows for adjustable ventilation rates, there are several disadvantages.</p> <p> </p> <p>Reducing the voltage to a motor also increases the amp draw, which in turn increases operating temperatures and decreases efficiency. </p> <p> </p> <p>Reducing the voltage by 50% doesn’t typically translate to a 50% reduction in speed or air delivery.  Since each brand of motor responds differently to voltage reduction, it can be difficult to know the exact ventilation rate a fan is delivering.</p> <p> </p> <p>It is generally advised not to operate voltage-regulated fans at speeds below 40-50% of their maximum rpm to prevent the motor from overheating.  Following this advice means using multiple smaller fans for minimum winter ventilation.</p> <p><img src="/images/uploaded/Blog/VFD/VFD-Control_900.jpg" alt="VFD Control" width="900" height="450" /></p> <p> </p> <p>Another method of speed control is Variable Frequency Drive or VFD.  A fan controlled by VFD uses a three-phase, single speed motor.  A VFD Controller receives a 0 to 10-volt signal from the house controller and sends a corresponding signal to the fan motor in frequency or hertz.  Using hertz to control fan speed has a significant advantage over voltage control including less motor overheating and improved energy efficiency.</p> <p>  </p> <p>The full range of a VFD fan varies from full delivery down to nearly zero.  This lower cfm range permits a producer to replace several smaller minimum fans on existing facilities with a single, larger VFD fan also functioning as a tunnel fan in the summer.</p>urn:store:1:blog:post:176https://hogslat.com/remodeling-project-increases-farrowing-crate-footprintRemodeling project increases farrowing crate footprint.<p>While litter size has steadily increased from 7.5 in the 1950's to 11.00 in the 2000's, the standard size of a farrowing crate has remained the same at 5'x7'.    When constructing new facilities, it is common for producers to increase the farrowing pens to 6'x 8' to accommodate for the expected larger litters.   Success with these larger pens sent producers looking for ways to remodel existing farrowing rooms without reducing the total number of crates. </p> <p> </p> <p>This article illustrates an example of a successful remodeling project converting 48 standard crates into a larger 5'6"x 9' size.</p> <p> </p> <p>The existing farrowing room consisted of four rows of (12) 5'x 7' crates.  The rows faced each other with a three-foot feeding alley in between.  A two-foot loading alley was located at the rear of each stall for an overall interior room width of 40 feet. Overall room length measured 66' with 60' long crate rows and two three-foot access alleys at each end.</p> <p></p> <p><img src="/images/uploaded/Retro farrowing crates/Remodel crate layout_900.jpg" alt="Remodel farrowing crate layout" width="900" height="692" /></p> <p> </p> <p>In the remodeling project, two rows of crates were faced to the outside walls with the two interior rows placed head-to-head.  This arrangement created two access alleys measuring approximately 24" between the crates.  Eliminating the access alleys at each row end provided an additional six inches of width in each crate.</p> <p> <img src="/images/uploaded/Retro farrowing crates/Crate-on-wall_900.jpg" alt="Swing side crates against wall" width="900" height="675" /></p> <p>Self-supporting, nine-foot-long TriDEK farrowing floors span three of the existing alleys.  Swing style crates angled in the pen allow for increased creep areas while enabling the pigs to move in front and at the rear of the crate.  Swing crates feature a moveable crate side that can be opened to remove the sow out the back of the stall eliminating the need for a front alleyway.</p> <p> <img src="/images/uploaded/Retro farrowing

your farm<p>Modern agriculture embraces many new technologies-Smartphones, wireless climate sensors, GPS crop monitoring, whole-house climate controls, and robotic cow milkers.</p> <p> </p> <p>So it makes perfect sense Electronic Sow Feeding has emerged as a popular system for group housing.  </p> <p> </p> <p>The system has several advantages-flexible pen layout, variable group sizes, the ability to feed sows individually, and digitalized Individual records.</p> <p> </p> <p>Without a doubt, many farms are utilizing ESF successfully.  However, this doesn’t mean this the only or even best system for group sow housing.  Group housing with feeding stanchions has proved itself across a wide range of production systems and locations.  There are several reasons for this success.</p> <p> </p> <p><strong>Your employees can already run a stanchion system.</strong></p> <p>In many ways, feeding stanchions are similar to gestation stalls.  The feed line drops the daily ration simultaneously, and sows stand at the trough until it is eaten.  The herdsman walks the pens checking the sows; animals not eating are quickly identified and treated.   Also, the group size tends to be smaller making it easier to sort the sows visually.</p> <p><img src="/images/uploaded/Blog/FeedSystem.jpg" alt="feed system" width="600" /></p> <p> </p> <p>In contrast, ESF systems rely on the stockmen’s ability to identify problem animals in a large pen.  Sows recognized by the system, as not eating, will need to be located by their ear tag in large group pen.   Also, animals require a training period where they learn to eat from an ESF station.</p> <p> </p> <p> </p> <p><strong>Equipment repairs can be performed in-house.</strong></p> <p>The feed system is the only moving part of a stanchion system.  This feed system relies on motors and simple switches to operate.  Most producers understand and can replace those components in an emergency. </p> <p> </p> <p><img src="/images/uploaded/Blog/sow-stachions-feeding.jpg" alt="sows eating in stanchions" width="600" /></p> <p> </p> <p>While ESF systems also have motors and switches they also utilize RFID readers, sorting gates, and electronic data transfer. While some individuals can troubleshoot and repair these items, those are the same people who can fix their own computer issues.  Most of us can’t.</p> <p> </p> <p><strong> </strong></p> <p><strong>If the dairy industry can use robotics why can’t we?</strong></p> <p>The dairy industry has an extensive and skilled dealer network in place. This dealer network is familiar with servicing compressors, milking equipment, etc.  The dealer network is also very dense.  Most diaries have multiple options for local service work.  Sow units tend to be located in more remote areas putting qualified service techs hours away. </p> <p> </p> <p> </p> <p>Off the record, and in some cases on the record, many producers with multiple group housing schemes express a preference for stanchions.  In fact, even though ESF systems have received more attention, our best estimate puts the number of new and remodeled sow places with stanchions to be over 600,000 in the U.S. This easily represents the largest number of sows housed in group systems.  No system is perfect, but for many producers, stanchions are the best choice for converting to group housing.</p> <p> </p>urn:store:1:blog:post:172https://hogslat.com/you-cant-afford-a-cheap-motorYou can’t afford a cheap motor<p><strong><img src="/images/uploaded/Blog/Auger-Repair_1540x800.jpg" alt="replacing ag motor" width="600" /></strong></p> <p></p> <p></p> <p><strong> </strong> </p> <p>Replacing motors on feed systems and ventilation fans is maintenance cost familiar to all hog and poultry growers.

Fluctuating voltage, common with rural power grids, can cause motor overloading even under normal system loads.</p> <p> </p> <p>Amp draw</p> <p>F.L.A. or Full Load Amps represents the amount of current the motor is designed to draw at the rated horsepower. In this case, the generic motor draws 6.4 amps while the GrowerSELECT motor is rated at 4.4 amps.

Heavier windings minimize heat buildup and dissipate the heat quicker.   Excessive heat is one of the primary causes of electric motor failure. In fact, for every 18 to 20 degrees increase in temperature, the expected motor life is cut in half. Other contributing factors to shortened motor life are related to component durability; such as aluminum wire usage, nondurable centrifugal switches along with less expensive start and run capacitors.</p> <p></p> <p> </p>urn:store:1:blog:post:168https://hogslat.com/evaporative-media-test-chamberEvaporative Media Test Chamber<p><img src="/images/uploaded/wp-content/uploads/2018/05/Evap-Test-Chamber_1540x800-1024x532.jpg" alt="Evap-Test-Chamber_1540x800" width="690" height="358" style="display: block; margin-left: auto; margin-right: auto;" /></p> <p>Evaporative pads, used on poultry or livestock buildings, require scheduled routine maintenance to remain effective. A recent addition to Hog Slat Inc.’s engineering facility will help provide producers with information focused on increasing the useful life of cool cell pads.</p> <p>“We are really excited to put the new Evaporative Media Test Chamber to work,” said Tyler Marion, project engineer, “So many times it is tough to do accurate evaluations under farm conditions. This equipment gives us a way to gather data using a controlled, repeatable approach. We can use a much smaller footprint to replicate conditions found in a tunnel-ventilated building. For instance, we can quickly evaluate a new product on the test chamber’s 14-foot long system compared to having to install 80 feet or 100 feet on full-sized production facility.”</p> <p><img src="/images/uploaded/wp-content/uploads/2018/05/Evap-Chamber-Inside_770x400-e1527260679534.jpg" alt="Evap-Chamber-Inside_770x400" width="600" height="312" style="display: block; margin-left: auto; margin-right: auto;" /></p> <p>“Because they are constantly saturated, pad life is greatly affected by the water quality on each farm,” Tyler explained, “The pH, hardness, and the amount of sediment of each water source account for a lot of the difference we see from farm to farm. Using the test chamber, we can simulate poor water conditions by changing the water pH or hardness. That will allow us to evaluate how different treatments such as algaecides and descalers affect pad life. We will also determine how or if different drying/saturated cycles contribute to pad failure.”</p> <p><img src="/images/uploaded/wp-content/uploads/2018/05/Evap-Chamber-controls_770x400-e1527260881424.jpg" alt="Evap-Chamber-controls_770x400" width="600" height="312" style="display: block; margin-left: auto; margin-right: auto;" /></p> <p>Tyler continued, “We can also accelerate product testing timeline due to the fan combination installed on the chamber. It is easily possible to double the static pressure and airspeed over normal rates, which causes a potential weakness to show up quicker. The new test chamber is a great tool to help us understand what factors contribute to product failure.”</p> <p>Hog Slat is a leading manufacturer of livestock and poultry live production equipment headquartered in Newton Grove, NC.   Hog Slat also provides turnkey construction services in the major production areas of the United States.</p>urn:store:1:blog:post:169https://hogslat.com/step-down-water-filtrationStep-Down Water Filtration<p><img src="/images/uploaded/wp-content/uploads/2018/04/Glass-dirty-water_1540x800-1024x532.jpg" alt="Glass-dirty-water_1540x800" width="690" height="358" style="display: block; margin-left: auto; margin-right: auto;" /></p> <p><strong>Step-Down Filtration systems improve sediment removal from the water sources used in livestock and poultry production.</strong></p> <p> </p> <p>Removing the sand, dirt, and organic matter is an essential first step in enhancing water quality. After removing the sediment, the water is further sanitized with chlorine dioxide or bleach to kill any pathogens.</p> <p><img src="/images/uploaded/wp-content/uploads/2018/04/Mesh-Micron-e1524506579518.jpg" alt="Mesh &amp; Micron" width="600" height="312" style="display: block; margin-left: auto; margin-right: auto;" /></p> <p>Here are some comparisons of standard mesh sizes and microns. Note the mesh sizes in parenthesis are not economically feasible to manufacture for farm use.</p> <p> </p> <p> </p> <p><strong>Step-Down Filtration</strong></p> <p>Unless the water source is extremely sediment free, most farms will benefit from installing a Step-Down system consisting of two filters.</p> <p><img src="/images/uploaded/wp-content/uploads/2018/04/Step-Down-Filter-Diagram_770x400-e1524506678370.jpg" alt="Step-Down-Filter-Diagram_770x400" width="600" height="312" style="display: block; margin-left: auto; margin-right: auto;" /></p> <p> </p> <p> </p> <p>The first step is a filter with a reusable screen between 60 and 140 mesh and easy-to-use flush valve. The idea is to trap the larger sediment, flush it often and prevent these particles from plugging the smaller filter downstream. One of the best examples of a first step filter is the<a href="http://www.hogslat.com/rusco-spin-down-t-style-filters"> Rusco Spin-Down® filter</a>. The clear housing makes it easy to tell when the filter is full and open the ball valve to quickly purge trapped sediment.  The reinforced polyester screen can be cleaned and reused.</p> <p><img src="/images/uploaded/wp-content/uploads/2018/04/Rusco_700x440-e1524856360684.jpg" alt="Rusco_700x440" width="600" height="312" style="display: block; margin-left: auto; margin-right: auto;" /></p> <p> </p> <p>The second step is determined by the watering or metering equipment is being used. Here are some recommended filter sizes for various types of equipment.</p> <p> </p> <p>Poultry drinkers – 20 microns</p> <p>Swine drinkers – 140 mesh</p> <p>Medicators – 200 mesh</p> <p>Evaporative Cooling Systems – 12 to 24 mesh</p> <p> </p> <p>For hog facilities, the second stage could easily be another flushable filter with a finer 200 or 240 mesh screen. For poultry houses, the second filter is typically a housing style that uses disposable cartridge filters to reach the recommended 10-50 microns. There are several types to choose from:</p> <p><img src="/images/uploaded/wp-content/uploads/2018/04/Filter-images700x440-e1524506823496.jpg" alt="Filter-images700x440" width="600" height="312" style="display: block; margin-left: auto; margin-right: auto;" /></p> <p><strong>Cartridge Filters</strong></p> <p>The most common and least expensive is a <a href="http://www.hogslat.com/polystring-filter-cartridges">string wound filter</a> manufactured with polypropylene cord. The manufacturing process creates distinct layers with looser wraps on the surface progressing to tighter layers near the core. Larger particles are trapped on the exterior to reducing plugging the denser interior layers. It is common for the string layers to separate over time allowing particles bigger than their specified rating to pass through.</p> <p>A second type is a <a href="http://www.hogslat.com/spun-polypropylene-filter-50-micron">spun poly</a> or melt blown cartridge made by blowing molten polymer over a spinning core. Known as gradient density filter, the media size gradually gets smaller towards the core. This type of filter maintains its micron rating better than string wound filters.</p> <p>A third type is a <a href="http://www.hogslat.com/pleated-water-filter-cartridges">pleated cartridge</a> that is commonly manufactured using a polyester material.   Pleated cartridges have more surface area to trap sediment, do not require replacement as often and have a higher flow rate. 20-micron, 4.5″x 10″ string wound filter has a typical flow rate of around 12 gallons per minute compared to a pleated model rated as high as 20 gallons per minute</p> <p><strong>Smaller isn’t better.</strong></p> <p>The best advice is to install a filter media with as large as openings as possible that will still perform the task. The larger the opening, the less the screen or cartridge will need to be cleaned or replaced.</p>urn:store:1:blog:post:170https://hogslat.com/whats-all-that-gunk-on-my-cool-cell-padsWhat's All That Gunk On My Cool Cell Pads?<p><img src="/images/uploaded/wp-content/uploads/2018/04/Scale-Algae_1540x800-1024x532.jpg" alt="Scale-Algae_1540x800" width="690" height="358" style="display: block; margin-left: auto; margin-right: auto;" /></p> <p><strong>Allowing mineral deposits and algae to accumulate on evaporative pads will eventually clog the pad openings causing a restriction of the airflow into the building.</strong></p> <p> </p> <p>When water evaporates, pure water is released leaving behind mineral deposits on the cool cell pads. The single best way to prevent the accumulation of mineral deposits is proper water distribution. Steady water flow over the pad surface flushes away minerals left by evaporation. In a system that is operating correctly, you should see a steady trickle of water down the outside of the pads with no visible dry streaks.</p> <p> </p> <p><strong>1) Start with clean pads</strong>. Remove dirt and other debris from the pads using a soft brush and low-pressure hose end sprayer. To remove heavy deposits of mineral and scale use a chemical cleaner like <a href="http://www.hogslat.com/triple-c-cool-cell-cleaner">Triple-C® by Proxy Clean</a>. Avoid using high-pressure sprayers and harsh chemicals containing bleach which can damage the pad media.</p> <p> </p> <p><img src="/images/uploaded/wp-content/uploads/2018/04/Spray-Bar-Brush770x400-e1523281698236.jpg" alt="Spray-Bar-Brush770x400" width="600" height="312" style="display: block; margin-left: auto; margin-right: auto;" /></p> <p> </p> <p><strong>2) Clean the spray bar.</strong> At the beginning of every season, open the ball valve on the pipe end; turn the pump on and flush water out the end. It is a good idea to mechanically scrub the inside of the pipe with a bottlebrush attached to a long PVC pipe. An inexpensive <a href="http://www.hogslat.com/hired-hand-cool-cell-clean-out-brush-kit">Clean-out Brush</a> is also available with a slip coupling that glues directly to a ¾” PVC pipe. Run the brush through the pipe and turn the pump on to flush the system a second time.</p> <p> </p> <p><img src="/images/uploaded/wp-content/uploads/2018/04/trough-cover_770x400-e1523281787588.jpg" alt="trough-cover_770x400" width="600" height="312" style="display: block; margin-left: auto; margin-right: auto;" /></p> <p> </p> <p>3) <strong>Clean the sump.</strong> Flush the trough and sump as dirt and sand quickly cause filters to plug. Remove several sections of pad and check the trough covers. Some trough covers have only minimum drainage holes, which allow dirt and sand to accumulate.</p> <p> </p> <p>4) <strong>Flush the filters.</strong> Install a ball valve on the filter clean out making it easy to remove trapped sediment. The screen element should be cleaned often and replaced every six to twelve months.</p> <p> </p> <p>5) <strong>Flush don’t bleed.</strong> While “bleeding-off” is better than nothing, a much better practice is to dump all the water from the trough and replenish it with fresh water. The complete dumping helps to flush the containments out of the cool cell pads. How often the trough needs to be drained depends on the hardness of the water and how often the evaporative system operates. Monitoring the pH level is a useful method to determine when to change the water with readings above 8.5 indicating an excessive mineral buildup.</p> <p> </p> <p> </p> <p>6) <strong>Check the pump size.</strong> Many times evaporative systems are extended without changing to a higher gallons per minute pump. Dry areas showing up at the end opposite the pump usually means an undersized pump. You can quickly check the pump size by using these general calculations:</p> <p> </p> <p>4-inch pads require .50 gallons per minute per linear foot</p> <p>6-inch pads require .75 gallons per minute per linear foot</p> <p> </p> <p> </p> <p>Cool cell pads are the perfect environment for algae growth providing light, moisture, and nutrients. Algae growth can be limited by following a few important management practices.</p> <p> </p> <p><strong>1) Limit sunlight</strong>. Algae growth requires only a few hours of sunlight per day. Cover sumps and filter housings to prevent algae growth. Consider installing an awning or roof to shade the system.</p> <p> </p> <p>2) <strong>Dry the pads.</strong> Allow the pads to dry completely once every 24 hours, as algae cannot live on a dry surface. If the system is not shutting down during the evening hours, it may be necessary to install a 24-hour timer.</p> <p> </p> <p>3) <strong>Limit nutrient content.</strong> Water from deep wells or municipal systems is preferred over surface water. Water from ponds or shallow wells is typically higher in nutrients.</p> <p> </p> <p>Only use chemical treatments approved for use with evaporative cooling systems. Bleach and many pool chemicals may damage the media and metal components. Don’t rely on chemicals to maintain an evaporative pad system. While the periodical use of descalers and algaecides may be helpful, there is no substitute for proper water flow and regular flushing of the system.</p>urn:store:1:blog:post:171https://hogslat.com/simple-guide-for-measuring-fan-v-beltsSimple Guide For Measuring Fan V-Belts<p><img src="/images/uploaded/wp-content/uploads/2018/04/replacement-fan-beltweb-e1522962721398.jpg" alt="replacement-fan-belt(web" width="600" height="400" style="display: block; margin-left: auto; margin-right: auto;" /></p> <p> </p> <p>Replacing the belts on fans every year is a smart investment to ensure they are delivering their maximum performance. Worn fan belts can cause as much as 20% loss of cfm output.</p> <p>Ordering the correct replacement fan belt is as easy taking a few simple measurements.</p> <p><img src="/images/uploaded/wp-content/uploads/2018/04/V-Belt-comparsion-web-e1522860451758.jpg" alt="V Belt comparsion (web)" width="600" height="312" style="display: block; margin-left: auto; margin-right: auto;" /></p> <p> </p> <p>First, to determine what type of belt is on your fan, measure the width of the belt. Most fan belts are A type belts with a measurement of 1/2″. If the fan belt measures 5/8″ it is classified as a type B belt. You may see a belt described as type AX. The X means it has a cogged design or notches in the belt. The cogged profile increases the power transfer and typically used for only industrial applications because of their higher cost.</p> <p><img src="/images/uploaded/wp-content/uploads/2018/04/V-Belts-Standard-Cogged-Drawing-770x400-e1522860611231.jpg" alt="V-Belts-Standard-Cogged-Drawing-770x400" width="600" height="312" style="display: block; margin-left: auto; margin-right: auto;" /></p> <p>Next, you need to measure the length of the belt. Use a cloth measuring tape (not a steel one) and wrap it around the outside of the belt. You also use a thin string to take this measurement and place it on a steel tape to get the correct length.</p> <p>Next, for “A” Belts (1/2” width) subtract two-inches from the outside measurement to select the correct V-belt. For example, if the outer measurement is 48-inches and you subtract two inches, then HSA46 would be the right belt for your fan.</p> <p>For “B” Belts (5/8” width) subtract 3” from the outside measurement to select the correct V-Belt. For example, if the outer measurement is 48-inches and you subtract three inches, then HSB45 would be the right belt for your fan.</p> <p>Hog Slat’s line of GroBelts offers producers top-quality V-belts at a great price.

Simple logic; cut the minimum winter rate by half from 2 cfm/pig to 1 cfm, and reduce LP usage by half. &nbsp;</p> <p>Unfortunately, this also increases the building's relative humidity along with higher gas and dust levels. The poorer environment can cause slow growth and increase the pigs&rsquo; susceptibility to disease. In some cases, this decreased lung function will hurt performance throughout the pig's production cycle. Lower ventilation rates can also jeopardize worker's health and cause the building's interior to deteriorate quicker. &nbsp;</p> <p>Solid sided finishing buildings, with insulated sidewalls replacing curtains, do not reduce the amount of minimum ventilation required to provide a good environment. Instead, the higher R-value walls significantly reduce the amount of heat loss compared to a curtain. The BTUs normally generated to replace heat loss through the curtains can instead be exhausted through the fans to improve the building's interior climate and pig performance. &nbsp;</p> <p>To illustrate the amount of BTU lost through a curtain sided finisher compared to a solid sided building we calculated the heat loss for a typical sized single wide finishing unit. &nbsp;</p> <p>Size: 1100 head Dem:<br />41&rsquo; x 224&rsquo; <br />Inside Temp: 70 <br />Outside Temp: 30 <br />Pig Size: 12 lbs. <br />Ceiling: R-30 <br />5&rsquo; Curtain: R-1 <br />3&rsquo; x6&rdquo; Concrete Wall: R-5 <br />5&rsquo; x6&rdquo; Insulated Wall: R-19 <br />Minimum ventilation rate: 2 cfm/head &nbsp;</p> <p>Ventilation Heat Loss <br />1100 head x 2 cfm/head= 2,000 cfm <br />2,000 x 60 = 120,000 cf/hr <br />120,000 x (70-30) x.018&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; = 86,400 BTU/Hr &nbsp; &nbsp; &nbsp;</p> <p></p> <p>Curtain Sided &nbsp;</p> <p>Ceiling 41 x 224 = 9,184 sq. ft. <br />9184 x (70-30) / R-30 &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; = 12,245 BTU/Hr&nbsp; &nbsp;&nbsp;</p> <p>End Walls 41x 8 x 2 = 656 sq. ft.<br />656 x (70-30) / R-19&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; = 1,381 BTU/Hr &nbsp;</p> <p>Concrete side wall 2&rsquo; x 224 x 2 = 896 <br />896 x (70-30) / 5&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; = 7,168 BTU/Hr &nbsp;</p> <p>Curtain 5&rsquo; x 224&rsquo; x 2 = 2240<br />2240 x (70-30) / 1 = &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; = 89,600/ BTU/Hr &nbsp; &nbsp; &nbsp; &nbsp;</p> <p></p> <p>Solid Sided &nbsp;</p> <p>Ceiling 41 x 224 = 9,184 sq. ft. <br />9184 x (70-30) / R-30&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp;= 12,245 BTU/Hr &nbsp; &nbsp;</p> <p>End Walls 41x 8 x 2 = 656 sq. ft. <br />656 x (70-30) / R-19&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp;= 1,381 BTU/Hr &nbsp;</p> <p>Concrete side wall 2&rsquo; x 224 x 2 = 896<br />896 x (70-30) / 5 &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; = 7,168 BTU/Hr &nbsp;</p> <p>Insulated Side wall 5&rsquo; x 224&rsquo; x 2 = 2240<br />2240 x (70-30) / 19 = &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; = 4,715/ BTU/Hr &nbsp;</p> <p>When we compare the curtain heat loss (89,600 BTU/ Hr) to the heat loss through the solid wall building (4,715 BTU/Hr.) the difference is close to 85,000 BTU/ Hr. &nbsp; &nbsp;</p> <p>The 85,000 BTU lost through curtain comes very close to equaling the amount of BTU exhausted through the ventilation system.

One-third of these fires occur in livestock and poultry operations with larger production facilities increasing the potential for catastrophic losses from replacement costs and interruptions in production schedules. &nbsp;</p> <p>Firestops or draft barriers<br />Firestops act as draft barriers to reduce the rapid spread of fire through an attic.&nbsp;&nbsp; Firestops consist of using a flame resistant material, such as 5/8-inch rated sheetrock covering both sides of a truss that contacts the roofline. Since any openings in the barrier reduce its effectiveness, the sheetrock should be notch to fit around the purlins. Install firestops every 100 feet of building length. &nbsp;</p> <p>Breakaway walkways <br />Use lightweight framing in the middle section of connecting hallways. If a fire breaks out in one building, a tractor and loader could be used to remove the center part preventing the fire from spreading to other buildings down the walkway.</p> <p><img class="aligncenter size-full wp-image-3189" src="/images/uploaded/wp-content/uploads/2018/01/Fire-escape-doors770x400-e1516635540475.jpg" alt="Fire-escape-doors770x400" width="600" height="312" style="display: block; margin-left: auto; margin-right: auto;" /></p> <p>Fire escape doors <br />Provide an exit door every 125 feet of the exterior wall to prevent areas where people could be trapped.&nbsp;&nbsp; Individual farrowing and nursery rooms should include some type of exterior escape door; site fabricated &ldquo;kick-out&rdquo; door, 36&rdquo;x 36&rdquo; window, or narrow walk door. &nbsp;</p> <p>Lighting protection <br />Any metal structures, such as bulk bins, located next to the buildings should be grounded with a ground rod for lightning protection. Install a surge protection device on the electric entrance panel. &nbsp;</p> <p>Incinerator and generator <br />Incinerators should be 50 feet or more from the buildings. Generator rooms inside a building should include walls with a 2-hour fire rating to delay the spread of a generator fire. <img class="aligncenter size-full wp-image-3191" src="/images/uploaded/wp-content/uploads/2018/01/FireEXtag-e1516637079803.jpg" alt="FireEX&amp;tag" width="600" height="312" style="display: block; margin-left: auto; margin-right: auto;" /></p> <p>Fire extinguisher <br />Install a 10-pound ABC dry chemical fire extinguisher at exterior doorways and electric panels.&nbsp;&nbsp; Provide additional units every 100 feet of building length. Fire extinguishers need to be checked monthly by the farm personnel and annually by an outside source. Have spare extinguishers to replace any used until they are recharged.</p> <p>Electrical systems <br />Return all repairs to the original installed condition. Three wire nuts and a roll of electrical tape, or whatever tape maybe handy, is a temporary fix but is often forgotten. Do not use electrical drop cords in place of permanent wiring. Do not bypass safety devices, sensors, breakers, fuses or other devices in a system; they are there for a reason. &nbsp;</p> <p>Train all employees on how to cut off the electrical power to individual buildings and the location of the primary cutoff for the entire facility. &nbsp;</p> <p>Heaters <br />Heaters and brooders are probably responsible for more barn fires than any other single source. Maintain heaters in good working condition, inspecting and servicing the heater components frequently, removing flammable foreign material, such as rodent nests, insects, and dust. Inspect rubber gas hoses for cracks. After any cleaning or servicing that requires removal of any part of the gas system check for leaks. Gas sniffers are cheap, typically $100 or less.&nbsp; Train all employees on how to shut off the gas to the entire facility. &nbsp;</p> <p>Heat lamps cords are highly susceptible to damage because they are frequently moved.&nbsp;&nbsp; Inspect the outside covering and replaced when the cord becomes worn or cracked and never repair damaged areas with electrical tape. &nbsp;</p> <p>Fire plan <br />Every farm should have a written plan detailing how employees should respond to fires and where to go in case of an emergency. Have all emergency numbers posted where all employees can access them and include the farm&rsquo;s 911 address. Implement and schedule quarterly fire drills.&nbsp; &nbsp; &nbsp;&nbsp;</p>urn:store:1:blog:post:165https://hogslat.com/solid-sidewall-finishers-growing-trend-in-new-constructionSolid sidewall finishers growing trend in new construction<p><img class="aligncenter size-large wp-image-3182" src="/images/uploaded/wp-content/uploads/2017/12/Barn_con1540x800-1024x532.jpg" alt="Barn_con1540x800" width="690" height="358" style="display: block; margin-left: auto; margin-right: auto;" /></p> <p>For the last 20-plus years, the industry standard for finishing houses has been some variation of a total slat, double-curtain building design. This style of construction utilized lower cost curtain construction on the sidewalls. &nbsp; As the design migrated north, some of the earliest adaptions to the buildings consisted of adding insulation to the sidewalls. Producers and builders used insulated or heavier weight curtains, removable bubble foil insulation and even eliminated the north curtain altogether replacing it with a solid insulated wall. &nbsp; A growing trend in new construction has seen a move away from curtain-sided finishing buildings. Several key factors have driven this movement to totally enclosed structures for finishing hogs.</p> <p>&nbsp; &nbsp; <img class="aligncenter size-full wp-image-3176" src="/images/uploaded/wp-content/uploads/2017/12/Thermal-images-e1513804459918.jpg" alt="Thermal-images" width="600" height="312" style="display: block; margin-left: auto; margin-right: auto;" /> <strong>Heat savings.</strong> Replacing the sidewall curtains with high R-value insulated, solid wall can significantly reduce the amount of heat needed when starting pigs. A simple heat loss comparison of a 200-foot exterior wall pointed to savings of up to 0.25 gallons of propane per hour. This building loss calculation also did not take into account the amount of heat needed to counter cold air leaks through tears or holes in the curtain or infiltration around the edges.</p> <p><img class="aligncenter size-large wp-image-3175" src="/images/uploaded/wp-content/uploads/2017/12/Solid-wall-ext_1540x800-1024x532.jpg" alt="Solid wall ext_1540x800" width="690" height="358" style="display: block; margin-left: auto; margin-right: auto;" /><strong></strong></p> <p><strong>Improved minimum ventilation.</strong> <br />The winter fans create a negative pressure inside the building drawing air from outside. Since even the best installed and maintained curtains are not airtight, cold outside air leaks in from around the curtains instead of entering through the ceiling inlets. Solid sidewalls eliminate curtain air leaks, so all the air comes through the ceiling inlets at a higher velocity. This cold, high-velocity air mixes with warmer room air near the ceiling before it swirls to pig level. &nbsp;</p> <p><strong>Reduced maintenance.</strong> <br />With no curtains, hardware or curtain machines to repair or replace, producers can eliminate the annual fall maintenance program saving time and money during the busy harvest season. &nbsp;</p> <p><strong>Improvements in fail-safe protection.</strong> Sidewall curtains provide fail-safe protection against power outages. A simple curtain drop device connected to the winch handle allows the curtains to drop down to prevent suffocation.&nbsp;&nbsp; In practice, this system many times does not function as intended because of poor repair and maintenance. Advanced alarm system technology linked to environmental controls alert barn operators almost immediately of power outages or drastic room temperature changes.</p> <p><img class="aligncenter size-full wp-image-3177" src="/images/uploaded/wp-content/uploads/2017/12/Solid-sidewall-interior-e1513805958456.jpg" alt="Solid-sidewall-interior" width="600" height="312" style="display: block; margin-left: auto; margin-right: auto;" /></p> <p>Several producers have remodeled existing curtain-sided buildings into solid sidewalls after seeing the benefits.&nbsp;&nbsp; The conversion is relatively straightforward with extra 2x6 studs added to the sidewall framing, exterior steel siding, 6-inch batt insulation and interior wall covering of plywood, Fiber Reinforced Plastic, poly board or metal siding. &nbsp;For interior panels in animal contact areas, do not allow the panel edge to extend over the concrete wall and cover all panel joints with aluminum batten strips.&nbsp; &nbsp;&nbsp;</p>urn:store:1:blog:post:164https://hogslat.com/your-next-livestock-medicator-should-be-electricYour next livestock medicator should be electric<p><img class="aligncenter size-full wp-image-3165" src="/images/uploaded/wp-content/uploads/2017/12/waterjar-650blog-e1513684356185.jpg" alt="waterjar-650blog" width="600" height="312" style="display: block; margin-left: auto; margin-right: auto;" /></p> <p>It is a standard production practice to use water driven medicators to administer medications, vaccines, and supplements to livestock and poultry.&nbsp; With good water quality and routine maintenance, virtually all brands of water driven medicators do an excellent job of accurately delivering the correct dosages. &nbsp;</p> <p>Poor water quality causes most of the problems producers experience when using this type of injection equipment.&nbsp;&nbsp; Water with high levels of dissolved chemicals (hard water) and impurities like sand and scale, can cause damage to seals, plungers, and pistons. Also, as some producers have moved to ABF production, chemicals used for water treatment have proved particularly corrosive to the moving parts of water driven medicators.</p> <p><img class="aligncenter wp-image-3159" src="/images/uploaded/wp-content/uploads/2017/12/Electric-Medicator-Installation-e1513622922254.jpg" alt="Electric-Medicator-Installation" width="600" height="312" style="display: block; margin-left: auto; margin-right: auto;" /></p> <p>Electric pumps used in the water treatment industry have proved effective in overcoming the problems with water quality and harsh chemicals.&nbsp;&nbsp; Drinking water does not travel through the pump; instead, it receives a signal from an in-line water meter. Based on the water flow passing through the meter, the electric pump injects accurate dosages from the stock tank directly into the water line. &nbsp;</p> <p><img class="aligncenter size-full wp-image-3163" src="/images/uploaded/wp-content/uploads/2017/12/peristaltic-pump-e1513622970405.jpg" alt="peristaltic-pump" width="650" height="338" style="display: block; margin-left: auto; margin-right: auto;" /></p> <p>The primary electric medicator currently in use for livestock and poultry production is the peristaltic pump. Peristaltic pumps use a roller device to squeeze stock solution through a hose or tube. The primary wear part is inexpensive tube kit that is easy to replace. Peristaltic pumps are excellent at delivering accurate dosages at low water flows, typical when starting new flock or group.&nbsp; <a href="http://www.hogslat.com/stennicator-1-128-fixed-ratio-medicator-pump">See Stennicator</a></p> <p><a href="http://www.hogslat.com/stennicator-1-128-fixed-ratio-medicator-pump"></a> <img class="aligncenter size-full wp-image-3169" src="/images/uploaded/wp-content/uploads/2017/12/Diaphragm-pump-e1513625004295.jpg" alt="Diaphragm-pump" width="650" height="338" style="display: block; margin-left: auto; margin-right: auto;" /></p> <p>Another type of electric pump uses a molded PTFE or Teflon diaphragm to dose chemicals. The Teflon diaphragm features excellent chemical resistance. Wear is virtually nonexistent on this part as the pumping movement amounts to only about 1/8" of flex. Diaphragm pumps handle low flows exceptionally well and also provide accurate metering at higher flows typically found at the end of a grow out period. &nbsp;</p> <p>The direct injection design of electric medicators allows operation in poor water conditions that damage water driven medicators.&nbsp;&nbsp;</p>urn:store:1:blog:post:163https://hogslat.com/medicator-aids-show-pig-productionMedicator aids show pig production<p><img class="aligncenter size-full wp-image-3151" src="/images/uploaded/wp-content/uploads/2017/12/show-pigs_3-blur-e1513198527988.jpg" alt="show-pigs_3-blur" width="600" height="400" style="display: block; margin-left: auto; margin-right: auto;" /></p> <p>Adding a water-based medicator adds flexibility to your management options.&nbsp;&nbsp; It's easier and quicker to switch medications and supplements in the water compared to using feed additives. Also, sick animals will drink water even if they aren't eating well. &nbsp;</p> <p><img class="alignleft size-full wp-image-3153" src="/images/uploaded/wp-content/uploads/2017/12/DM11F_hoses_web-e1513199701696.jpg" alt="DM11F_hoses_web" width="300" height="334" style="display: block; margin-left: auto; margin-right: auto;" /></p> <p>Most show pig producers with more than a few pigs have automated their water supply by installing a water line and either nipple or cup drinkers in each pen.&nbsp;&nbsp; Plumbing a medicator into this water system is relatively straightforward.&nbsp;&nbsp; Start by installing a ball valve in the PVC pipe and plumbing a by-pass to direct incoming water through the medicator. The by-pass can be constructed of PVC pipe with ball valves, or an alternative method uses hose bibs with 5/8" drinker hose.&nbsp;&nbsp; This alternative method is ideal for use in multiple locations, simply remove the hoses, detach the unit from the wall and move the whole assembly to the next barn. &nbsp; &nbsp; &nbsp; To use the medicator, dry powders or liquid concentrates are dissolved in water (according to package directions) creating a stock solution. The suction hose from the medicator is placed in the stock tank (typically a 5-gallon bucket). The water flow from the drinking system passes through the medicator, drawing solution from the stock tank and mixing the stock solution into the pig&rsquo;s drinking water. &nbsp;</p> <p><img class="alignleft size-full wp-image-3155" src="/images/uploaded/wp-content/uploads/2017/12/DM11-cutaway_web-e1513200401260.jpg" alt="DM11-cutaway_web" width="300" height="397" style="float: left;" /></p> <p>The Dosatron DM11F medicator is one of the best choices for use with show pig herds. Because it is water powered, it requires no electricity to use, making it easy to move.&nbsp;&nbsp; The DM11F automatically compensates for changing water flows and pressures providing consistent, repeatable dosing.&nbsp;&nbsp; Its diaphragm water motor also enables the DM11F to operate at water flows as low as .02 gallons per minute.

Stations protect baits from rain and dirt, helping the rodenticides stay fresh and potent longer while providing security against access from children and pets. Bait stations also provide an environment where rats and mice feel secure when feeding on baits.</p> <p style="text-align: justify;"><img class="aligncenter size-full wp-image-3144" src="/images/uploaded/wp-content/uploads/2017/11/Bait-Placement-e1511200432739.jpg" alt="Bait Placement" width="600" height="312" style="display: block; margin-left: auto; margin-right: auto;" /></p> <p style="text-align: justify;">Rodents are creatures of habit and travel along established paths between their nests and food supply. They will not go out of their way to visit bait stations outside their normal traffic areas. Look for signs of rodent activity such as droppings, tracks and gnawing to locate pathways. Place mouse stations 10-13 feet apart as mice seldom venture more than 50 feet from their nests. Rats range much farther afield allowing station placement to be between 25 and 50 feet apart.</p> <p style="text-align: justify;"><img class="aligncenter size-full wp-image-3145" src="/images/uploaded/wp-content/uploads/2017/11/Bait-Stations-e1511200536544.jpg" alt="Bait-Stations" width="600" height="312" style="display: block; margin-left: auto; margin-right: auto;" /></p> <p style="text-align: justify;">Do not use mouse stations when rats are present as the bigger rodents will gnaw through the thinner plastic and expose the baits. Consider using white colored bait stations for those locations on the south exposure of buildings. The interior temperature of black colored stations can increase by as much as 30&deg; which may melt some bait formulations.</p> <p style="text-align: justify;"><img class="aligncenter size-full wp-image-3146" src="/images/uploaded/wp-content/uploads/2017/11/T-Station-e1511200575850.jpg" alt="T Station" width="600" height="312" style="display: block; margin-left: auto; margin-right: auto;" /></p> <p style="text-align: justify;">Securely fasten stations to walls or floors to prevent them from being moved out of the traffic pathway. Use tent stakes to anchor bait stations to the ground for exterior placement. T-style stations are very versatile in their applications. Nylon ties are used to fasten them to gate rails, rafters, and even feed pipes.</p> <p style="text-align: justify;">Check bait stations on a monthly basis as part of the routine barn maintenance program adding fresh bait as needed. Rodents will often refuse to eat spoiled or stale bait. Observe the condition of the stations themselves as plastic can become brittle, especially the lid hinge. Stations with rotating hinges will outlast models with thin bendable strips of plastic called living hinges. During periods of heavy infestation, it may be necessary to check daily to ensure an adequate supply of bait. Stations are available with clear lids to allow a visual check of bait levels without opening the lid.</p> <p style="text-align: justify;">It is important to be patient when dealing with rat infestations. Rats are suspicious of new objects in their territory, and it may be several weeks before they use a new bait station. Leave stations in place even after a heavy infestation is under control. Rats are more likely to enter bait stations that have become part of the "terrain" when baiting occurs in following seasons.</p> <p>Go to <a href="http://www.hogslat.com/rat-mouse-bait-stations">bait stations</a> for pricing and ordering information.&nbsp;&nbsp;</p>urn:store:1:blog:post:161https://hogslat.com/features-of-a-well-designed-backyard-nest-boxFeatures of a well designed backyard nest box<p style="text-align: justify;">Providing your flock with proper nesting boxes ensures they have a comfortable, secure place to lay their eggs.

It is not necessary or even desirable to provide additional nest boxes. Besides the initial cost, extra nests require more bedding material, encourage chickens to roost in the empty slots, and take more time to clean. &nbsp; Install the nests at least 18" to 20" above the floor preferably on a wall away from the roosting area.&nbsp;&nbsp; Because chickens like to roost in the highest part of the house, do not place the nests higher that the roosting perches. If possible try not to place the nests above feed and water to prevent contamination from nesting material and droppings.</p> <p style="text-align: justify;"><img class="aligncenter size-full wp-image-3134" src="/images/uploaded/wp-content/uploads/2017/11/nest-top-e1511195227740.jpg" alt="nest-top" width="614" height="309" style="display: block; margin-left: auto; margin-right: auto;" /></p> <p style="text-align: justify;">The nests should be designed with 45&deg; sloped roof to prevent the hens from roosting on top. <img class="aligncenter size-full wp-image-3135" src="/images/uploaded/wp-content/uploads/2017/11/Perches-e1511195298578.jpg" alt="Perches" width="600" height="300" style="display: block; margin-left: auto; margin-right: auto;" /></p> <p style="text-align: justify;">Provide a perch just below the opening for the birds to land on before entering. Nests with foldable perches allow the nest to be shut off at night to prevent roosting.

For any animal to reach its full genetic potential, we must manage the water to achieve the correct pH level in its gut. &nbsp; The pH is a measure of acidity and alkalinity. A pH of 7 is neutral; less than 7 is considered acidic and over 7 alkaline. Water pH is a major factor in determining the effectiveness of various water treatments. &nbsp; Adjusting the pH into the acidic range benefits the animal's GI tract by creating a detrimental environment for pathogenic biology. Other research points to improvements in nutritional impacts of feed at lower pH levels with organic (chemically organic &ndash; so containing carbon) acids. There may even be benefits we still don&rsquo;t understand yet with pH reduction in livestock while realizing the benefits. &nbsp; The available data reflect these benefits, regardless of their mode of action.&nbsp;&nbsp;</p> <p style="text-align: justify;"><img class="aligncenter size-full wp-image-3117" src="/images/uploaded/wp-content/uploads/2017/11/pH-chart-e1509647776317.jpg" alt="pH-chart" width="600" height="312" style="display: block; margin-left: auto; margin-right: auto;" /></p> <p style="text-align: justify;"></p> <p style="text-align: justify;">Terminal line disinfection in this research trial was achieved with a 3% solution of Peraside (peracetic acid disinfectant) administered into the lines with a sump pump upon depopulation. The solution sat in the lines overnight and was flushed the next morning with fresh water. All drinkers were triggered to ensure proper function before placing the pigs. Disinfection was achieved with 5ppm of MaxKlor (stabilized chlorine dioxide), and the pH was set to a pH of 6.5 to 6.8 using Dyne-O-Might (blended organic/mineral stabilized with iodine)</p> <p style="text-align: justify;">&nbsp; <img class="aligncenter size-full wp-image-3118" src="/images/uploaded/wp-content/uploads/2017/11/Water-pH-e1509647845547.jpg" alt="Water-pH" width="600" height="312" style="display: block; margin-left: auto; margin-right: auto;" /></p> <p style="text-align: justify;">Water meters measured flow rates and triggered electric pumps for a precise chemical injection. This equipment ensured every gallon received the targeted treatment even with the small dosing requirements needed.

A field test comparing the two systems was set up on a farm in Indiana.</p> <p style="text-align: justify;"><img class="aligncenter size-full wp-image-3104" src="/images/uploaded/wp-content/uploads/2017/09/Brooder-Bldg-Diagram770x400-e1505937068644.jpg" alt="Brooder-Bldg-Diagram770x400" width="600" height="312" style="display: block; margin-left: auto; margin-right: auto;" /></p> <p style="text-align: justify;">The layout of the test setup is shown in Figure 1. The 40' x 200' test rooms were in the same building separated by a wall with 18 brooders installed in each room. The 17,100 Btu brooders were mounted three feet above the floor.&nbsp;&nbsp; The Modulating Control thermostat sensor and High/Lo thermostat sensor are shown as T1 and T2, respectively. The Brooder temperature set point was 85&deg;. &nbsp;</p> <p style="text-align: justify;">A gas furnace provided auxiliary heat for each room with its thermostat location indicated by the T in Figure 1.&nbsp;&nbsp; The outdoor temperature was measured using a thermocouple as shown as T3. All sensors were four feet above the floor level. A gas meter was mounted in each room to record the fuel consumption of the corresponding control system. &nbsp;</p> <p style="text-align: justify;"><img class="aligncenter size-full wp-image-3105" src="/images/uploaded/wp-content/uploads/2017/09/Table-21-e1505937125669.jpg" alt="Table-2" width="600" height="312" style="display: block; margin-left: auto; margin-right: auto;" /></p> <p style="text-align: justify;">Figure 2 shows the results of the field test with a 20.7% fuel savings for the Hi/ Lo regulated brooders. &nbsp; &nbsp;</p> <p style="text-align: justify;"><strong><br /></strong></p> <p style="text-align: justify;"><strong>Why did these savings occur? </strong></p> <p style="text-align: justify;"><strong></strong> At high demand, the gas consumption is the same for both control panels at the maximum input. At low demand, the gas consumption is the same for both control panels at the minimum input. &nbsp;</p> <p style="text-align: justify;">The savings occur between the two extremes. It is more cost-effective for the brooder to switch between high and low than to maintain the temperature with the less efficient pressure settings in between. <strong>&nbsp;</strong> <strong>&nbsp;</strong></p> <p style="text-align: justify;"><strong>What about temperature swings under the brooder? </strong></p> <p style="text-align: justify;"><strong></strong> The internal temperature of the brooders only varies by two degrees.&nbsp; This temperature variant is in the brooder and is reflected not on the temperature recorded on the floor below.&nbsp;&nbsp;</p> <p style="text-align: justify;"><img class="aligncenter size-full wp-image-3106" src="/images/uploaded/wp-content/uploads/2017/09/Control-Panel-e1505937239871.jpg" alt="Control-Panel" width="600" height="312" style="display: block; margin-left: auto; margin-right: auto;" /></p> <p style="text-align: justify;">Also, a style Hi/Lo panel is easier to integrate into a whole house environmental control system.

However, that is not always the case. This article gives an understanding of what to look for and why rotating active ingredients is an important step to your biosecurity rodenticide rotation. &nbsp;</p> <p style="text-align: justify;"><img class="aligncenter size-full wp-image-3094" src="/images/uploaded/wp-content/uploads/2017/09/Liphatech-Soft-Bait-Sachets-770x400-e1505916483132.jpg" alt="Liphatech Soft Bait Sachets 770x400" width="600" height="312" style="display: block; margin-left: auto; margin-right: auto;" /></p> <p style="text-align: justify;">Knocking down a rodent population can be a difficult, but very important process. This is where a highly palatable rodenticide comes into play. The active ingredient Difethialone is powerful enough to be formulated into rodenticides at half the dose (0.0025%) of its rotation partners. Products containing Difethialone are very palatable. Difethialone is a second-generation anticoagulant active ingredient, commonly referred to as a blood thinner, and kills rodents within 4-5 days after a single nights feeding. Anticoagulants prevent or reduce the coagulation of blood, resulting in uncontrolled bleeding. These delayed effects mean that rodents may return to consume more bait, due to the symptoms not taking place immediately. The cornerstone of an effective rodent control program should start with rodenticides containing Difethialone for six months, which when used and consumed consistently, will control multiple levels of the social hierarchy within your rodent population. Difethialone is available in a soft bait (FastDraw), block, or pellet (Hombre) formulation. &nbsp;</p> <p style="text-align: justify;">After using Difethialone for six months and seeing a reduction in dead rodents or signs of activity, rotate to a product containing Bromadiolone. Bromadiolone is also a second-generation anticoagulant active ingredient typically formulated at 0.005% and is available in soft bait (Revolver), blocks, or pellets (BootHill). Bromadiolone is a great rotation partner to keep rodents at a manageable level, and the paraffinized pellets are labeled for burrow baiting to allow flexibility when controlling Norway rats. This rodenticide also provides a different flavor profile, for rodents with flavor preferences that may not have been attracted to other rodenticide brands. Bromadiolone is recommended for four months and kills rodents within 4 to 5 days after consuming a lethal dose. &nbsp;</p> <p style="text-align: justify;"><img class="aligncenter size-full wp-image-3095" src="/images/uploaded/wp-content/uploads/2017/09/Cannon-770x400-e1505916583788.jpg" alt="Cannon 770x400" width="600" height="312" style="display: block; margin-left: auto; margin-right: auto;" /> &nbsp;</p> <p style="text-align: justify;">When rotating from Bromadiolone, use a rodenticide containing Bromethalin for two months or during depopulation periods. Bromethalin is an acute toxicant that causes damage to the central nervous system and controls both mice and rats in as little as 48 hours after a single night&rsquo;s feeding. This rapid kill is necessary when you need to effectively eliminate rodent populations during short depopulation periods, before introducing a new flock or group into the building. Due to the rapid onset of symptoms, rodents typically cease feeding after consuming a lethal dose, which may, in turn, save you money from over-consumption. Using bromethalin also breaks the anticoagulant cycle in your biosecurity rodent control program, which is critical to ensure your rodent population does not become resistant to anticoagulant rodenticides. Bromethalin is available in a soft bait (Cannon) or block (Gunslinger) formulation. &nbsp;</p> <p style="text-align: justify;"><img class="aligncenter size-full wp-image-3096" src="/images/uploaded/wp-content/uploads/2017/09/Liphatech-Rotation-with-Taglines-e1505916653315.jpg" alt="Liphatech-Rotation-with-Taglines" width="600" height="312" style="display: block; margin-left: auto; margin-right: auto;" /></p> <p style="text-align: justify;">Following a rotation such as&nbsp;will ensure you are using a variety of active ingredients.

As the weather cools, regulating the environment inside livestock and poultry buildings becomes more difficult with manually operated vent doors. Adding small ventilation fan(s) simplifies the task of maintaining a healthy environment for the animals. &nbsp;</p> <p style="text-align: justify;">The first step is to determine the minimum and mild winter rates for the amount of the animals housed. Table 1 displays a chart with recommended ventilation rates taken from an older university manual. <img class="aligncenter size-full wp-image-3084" src="/images/uploaded/wp-content/uploads/2017/09/Table-1-e1505848487331.jpg" alt="Table-1" width="600" height="297" style="display: block; margin-left: auto; margin-right: auto;" />Minimum rates are the recommended ventilation in cfm (cubic feet per minute) needed to control moisture and prevent condensation from forming on interior surfaces. The additional mild winter airflow stops rising temperatures inside the building as the outside temperature increases. &nbsp;</p> <p style="text-align: justify;">For our example, we'll use a 24' x 30' farrowing house with ten crates. &nbsp;</p> <p style="text-align: justify;">10 sows/litters x 20 cfm = 200 cfm&nbsp;&nbsp; minimum rate<br />10 sows/litters x 80 cfm = 800 cfm&nbsp;&nbsp; mild winter rate&nbsp;&nbsp;</p> <p style="text-align: justify;">As a fan operates, it creates a static pressure difference between the inside and outside of the building measured in water column inches. Pick an exhausted fan for this application according to its stated cfm deliveries at .05" static pressure. (<a href="http://www.hogslat.com/shutter-exhaust-fan-pre-wired">See Farmstead Fans</a>)</p> <p style="text-align: justify;"><img class="aligncenter size-full wp-image-3085" src="/images/uploaded/wp-content/uploads/2017/09/Table-2-e1505848530128.jpg" alt="Table-2" width="600" height="367" style="display: block; margin-left: auto; margin-right: auto;" />From the list of fans shown in Table 2, the 12" fan is rated at 880 cfms.&nbsp;&nbsp; This cfm rating matches up closely with the mild winter rate in our example.&nbsp;&nbsp; We have two options that will enable us to reduce the cfm delivery down to the minimum rate of 200 cfm. &nbsp;</p> <p style="text-align: justify;">We can use an inexpensive variable speed controller to slow the speed of the fan. (<a href="http://www.hogslat.com/variable-speed-fan-control">see #NE105F</a>) But be aware that a reduction in fan speed does not directly mean the same reduction in cfms. In other words, reducing the fan speed by 50% does not reduce air delivery by 50%.&nbsp;&nbsp; Turning a fan down too slow can also cause the motor to overheat. &nbsp;</p> <p style="text-align: justify;">A more accurate method of reducing the amount of air exhausted is using a cycle timer. (<a href="http://www.hogslat.com/grower-select-30-min-adjustable-duty-cycle-timer">see HST001</a>) In the example above we would set the on cycle for one minute and off cycle for four minutes. &nbsp;</p> <p style="text-align: justify;">20 cfm x 10 sows = 200 cfm <br />200 cfm/ 880 fan cfm = 0.227 x 300 sec (Total Cycle Time) = 68 sec ON or 1 minute &nbsp;</p> <p style="text-align: justify;">The additional advantage of using a timer is it allows more flexibility for changing animal density. For instance, if our example farrowing barn was half full we could reduce the on cycle to one minute. If we chose to wean the pigs in the crates and leave them there until they weigh 40 lbs., we would be able to increase the on time to two minutes. &nbsp;</p> <p style="text-align: justify;">120 pigs x 3 cfm = 360 cfms<br />360 cfm / 880 cfm = 0.409 x 300 sec (Total Timer Cycle ) = 123 sec ON or 2 minutes &nbsp; &nbsp;</p> <p style="text-align: justify;">Either the speed control or timer can be wired in parallel with a single stage thermostat to override the low setting. As the temperature rises inside the building, the thermostat takes over and runs the fan at full speed. If the inside temperature goes down with the fan running on high the thermostat drops out, and timer takes over, and the building returns to minimum ventilation. &nbsp;</p> <p style="text-align: justify;">Operating the minimum ventilation during cold weather will mean adding supplemental heat to maintain a comfortable temperature for the animals. Turning the fan down to prevent the heater from running will create damp, smelly air inside the barn.&nbsp;&nbsp; Table 3 lists the likely supplemental heat requirements per animal. These rates assume adequate insulation in the walls and ceiling and minimum air leaks.</p> <p style="text-align: justify;"><img class="aligncenter size-full wp-image-3086" src="/images/uploaded/wp-content/uploads/2017/09/Table-3-e1505848657552.jpg" alt="Table-3" width="600" height="289" style="display: block; margin-left: auto; margin-right: auto;" /></p> <p style="text-align: justify;">Using our example barn again &nbsp;</p> <p style="text-align: justify;">20 sows/litters x 3000 Btu = 60,000 Btu heater<br />or <br />120 nursery pigs x 350 = 42,000 Btu heater. &nbsp;</p> <p style="text-align: justify;">Also, you will need to provide air intakes matched to the total ventilation capacity of the fans. A simple gravity activated sidewall inlet <a href="http://www.hogslat.com/single-sidewall-inlet-55-x-225">(see #HSI200)</a> is the best choice for most situations. Inexpensive and easy to install, this simple plastic inlet automatically opens allowing airflow when the fan(s) operate. When the timer shuts the fan off, the plastic louver closes. &nbsp;</p> <p style="text-align: justify;">Inlets installed in an outside wall require a weather hood to protect against strong winds forcing the louver open.&nbsp;&nbsp; See Weather Hood diagram below. Inlets are typically located opposite the fan(s) to pull air across the building.&nbsp;&nbsp;</p> <p style="text-align: justify;"><img class="aligncenter size-full wp-image-3089" src="/images/uploaded/wp-content/uploads/2017/09/weatherhood-e1505849284531.jpg" alt="weatherhood" width="600" height="459" style="display: block; margin-left: auto; margin-right: auto;" /></p> <p style="text-align: justify;">Each inlet is rated at 430 cfm. To determine the number of inlets needed divide the total cfm by 430. Using our example &nbsp;</p> <p style="text-align: justify;">880 cfm/ 430 = 2.04 or 2 inlets needed. &nbsp;</p> <p style="text-align: justify;">We provided this short article as a guide to adding wintertime ventilation to an existing building.

Simply put, you can&rsquo;t do these things without the use of ID devices. Whether you are using traditional tags or possibly electronic identification tags (EID) or a combination of both, what you do on your operation is made easier by the use of an ID product. &nbsp;</p> <p style="text-align: justify;">Inventory, piglets per litter, breeding information, performance data, treatments and withdrawal records are all tied to an animal ID. From simple to complex, you design the process that best works for your operation. Many producers have decided to use electronic ear tags to help increase the accuracy of their record-keeping and reduce the labor needed to perform routine tasks that require identifying individual animals. The use of EID in swine continues to grow and become the norm in group sow housing as electronic sow feeders continue to become more prominent in our market. &nbsp;So a single tag can be used for individual sow feed management in addition to the information commonly managed with an ID tag.</p> <p style="text-align: justify;"><strong>How?</strong> &nbsp;</p> <p style="text-align: justify;">Pick the product. From piglet tags to the center post, breeding herd tags, there are different products for an animal&rsquo;s age. &ldquo;Mating the proper tag with the production phase/age of the pig is important to reach your identification goals, ease of application and retention,&rdquo; according to Steve Bretey, Swine Business Manager for Allflex USA/ Destron Fearing. &ldquo;Plan ahead, and place your order two or three weeks before needing them.&rdquo; &nbsp;</p> <p style="text-align: justify;">Always use the same brand of applicator and tags. There are slight differences between tags, and it is important to use the proper applicator. &nbsp;(Following package directions is also a big help in getting the correct applicator with the tag.) &nbsp;</p> <p style="text-align: justify;">Use disinfectant on the stem of the male tag. Just dip the stem in the disinfectant, not the whole tag. This action will help lubricate the tag and improve the cleanliness of the application process. <strong>&nbsp;</strong></p> <p style="text-align: justify;">Different numbering system<strong>s </strong>can be used on visual ear tags, but the best is simple to use and understand. Always make the management number the biggest number on the tag, knowing it&rsquo;s the most important. You can also add sire codes, genetic lines, etc. to the tag with other smaller numbers. Last but not least consider color and important option. Colors can represent genetic lines, age, location, etc. to help more quickly identify and manage your animals. &nbsp;</p> <p style="text-align: justify;"><img class="aligncenter size-full wp-image-3071" src="/images/uploaded/wp-content/uploads/2017/08/DF_SP_Pink_Webres-e1503687991567.jpg" alt="DF_SP_Pink_Webres" width="650" height="338" style="display: block; margin-left: auto; margin-right: auto;" /> Official Tags-Swine premises tags continue to be one of the most successful industry driven programs in the US. Cull Sows and Boars are required to be tagged with an official tag before entering harvest channels.

Animals get water in three ways. The first is respiration. The amount of water ingested this way, however, is negligible, especially when you are talking water that&rsquo;s actually usable by the animal nutritionally. The second way the animal gets water is through the feed. Again, this is negligible. The main way the animal gets essentially all of the water it uses for existence comes through the water line in the barn. &nbsp;</p> <p style="text-align: justify;">Making sure that water works for the animal, instead of hindering it, will make sure the animal thrives, rather than just survives. One part of this process is disinfection of the water to make sure the water isn&rsquo;t adding pathogens into the animal with every drink. Water sources are often contaminated, especially those that are surface water or have been in use for more than a couple years. Over time water sources are often disturbed by geological forces, continued tapping by other users, and through routine maintenance on the well system. Animal drinkers are also open, meaning air or debris from the environment can mix with the water prior to consumption by the animal. This leads to contamination after the point of disinfection, so steps should be taken to ensure any chemical used to reduce pathogens in the water is effective past the point of injection and reaches the mouth of the animal. &nbsp;</p> <p style="text-align: justify;"><img class="aligncenter size-full wp-image-3076" src="/images/uploaded/wp-content/uploads/2017/08/Anthium-Dioxcide_770x400-e1503688659993.jpg" alt="Anthium-Dioxcide_770x400" width="650" height="338" style="display: block; margin-left: auto; margin-right: auto;" /></p> <p style="text-align: justify;">There are many, many options for water disinfection. One that has shown great results in disinfection of the novel pathogens we deal with in the animal production is chlorine dioxide. Chlorine dioxide is similar to bleach in that it is a chlorinated compound, but is 2.6 times the strength when it comes to oxidizing the pathogens. Also, it has multiple modes of action instead of just oxidation. This means it kills pathogens that show resistance to chlorine bleach, and these resistant pathogens are becoming more and more common in animal production. Chlorine dioxide typically comes in a container with &ldquo;stabilized chlorine dioxide&rdquo; on the label and converts to chlorine dioxide when applied in the water. The amount of conversion is dependent on how it is &ldquo;activated&rdquo; with release agents (like acids, hypochlorite, electricity, or other catalysts). Chlorine dioxide also has a taste and odor control claim on its label, so it can be used in situations where increased consumption by the animals is a goal for the producer.</p> <p style="text-align: justify;">Data shows chlorine dioxide treatment of drinking water can significantly improve production values. Application of the stabilized chlorine dioxide in this trial improved production at the research site as follows:</p> <p style="text-align: justify;">6-week wean-nursery trial &ndash; Pathogen reduction with stabilized chlorine dioxide after terminal line disinfection with peracetic acid (MaxKlor, Neogen Corp. and Peraside, Neogen Corp.)</p> <p style="text-align: justify;"><img class="aligncenter size-full wp-image-3077" src="/images/uploaded/wp-content/uploads/2017/08/Chart_2_770x400-e1503688697613.jpg" alt="Chart_2_770x400" width="650" height="338" style="display: block; margin-left: auto; margin-right: auto;" /></p> <p style="text-align: justify;">Terminal line disinfection in this research trial was achieved with a 3% solution of peracetic disinfectant administered into the lines with a sump pump upon depopulation. The stabilized chlorine dioxide was run at a rate of 5ppm for consumption through the nursery phase. The solution was created and maintained by a metering pump.</p> <p style="text-align: justify;"><img class="aligncenter size-full wp-image-3078" src="/images/uploaded/wp-content/uploads/2017/08/Electric-Pump-System._770x400jpg-e1503688740908.jpg" alt="Electric-Pump-System._770x400jpg" width="650" height="338" style="display: block; margin-left: auto; margin-right: auto;" /></p> <p style="text-align: justify;">An electric metering pump runs off a water meter or pressure switch to apply the correct amount of solution to the injected into each gallon of water in the lines. The producer places the tube directly into the disinfectant and is not exposed to the product. The producer runs the pump and makes adjustments based on a simple test strip test taken from an actual drinker &ndash; because it&rsquo;s about what the animal is drinking, not what is in the original water source.</p> <p style="text-align: justify;">With a little effort, since stock solutions are not needed and only a jug needs to be replaced, these production gains can be realized, and the animals can move further towards their genetic potential.&nbsp; &nbsp;&nbsp;</p>urn:store:1:blog:post:153https://hogslat.com/its-not-a-battle-its-a-warIt’s not a battle; it’s a war.<p style="text-align: justify;"><img class="aligncenter size-large wp-image-3061" src="/images/uploaded/wp-content/uploads/2017/08/Mouse-Feed-Pile-1540x800-1024x532.jpg" alt="Mouse-Feed-Pile-1540x800" width="690" height="358" style="display: block; margin-left: auto; margin-right: auto;" /> &nbsp;</p> <p style="text-align: justify;"><strong>Win the war against rats and mice with these three steps for effective use of rodenticides. </strong> &nbsp;</p> <p style="text-align: justify;">Cool temperatures are fast approaching meaning mice and rats will be looking for a warm place to live (your production facility). This article provides the basic information needed for an effective year-round biosecurity rodent control program. Due to the biosecurity risk rodents present 12 months out of the year, rodent control should be an area of focus every time the staff steps into a production facility. Selecting the right rodenticide rotation program is critical to prevent disease outbreaks, lower feed costs, reduce resistance, and to decrease building damage. Here are three steps to consider when building your program. <img class="aligncenter size-full wp-image-3064" src="/images/uploaded/wp-content/uploads/2017/08/Liphatech-Rotation-e1503687218741.png" alt="Liphatech Rotation" width="650" height="338" style="display: block; margin-left: auto; margin-right: auto;" /></p> <p style="text-align: justify;">Step 1: <strong>Using the right rodenticide rotation</strong>. There are many rodenticide formats to choose from such as soft baits, blocks, pellets, and meal bait. Soft baits are the best option for the year-round knock down of rodents. Soft baits contain no wax to prevent baits from melting or freezing which maintains palatability. Additionally, more placements per pail result in lower cost per placements. Soft baits also provide flexibility to bait in hard to reach places, discussed in step 2. However, not every rodent will feed on any particular type of rodenticide so rotating the active ingredient every 2-6 months is critical. Switching the bait formats between blocks, pellets or soft baits also takes into account rodent taste preference.&nbsp;&nbsp; An effective rodenticide rotation provides the flexibility to rotate between three active ingredients and textures. &nbsp;</p> <p style="text-align: justify;"><img class="aligncenter size-full wp-image-3065" src="/images/uploaded/wp-content/uploads/2017/08/FastDraw-in-Hog-Barn-e1503687281135.jpg" alt="FastDraw in Hog Barn" width="650" height="338" style="display: block; margin-left: auto; margin-right: auto;" /></p> <p style="text-align: justify;">Step 2: <strong>Putting the right bait in the right location</strong>. Start with a building inspection working from the exterior to the inside. Carefully and thoroughly inspect exterior and interior walls, attics, curtains, manure pits, and other places where rodents may hide or live. Areas, where the feed lines enter the sides of the building, are common entry points. Look for nests and signs of rodent damage or traffic. These may be areas like entry and exit points, feces alongside walls, gnawed openings between floors or walls, beside burrows, or locations where rodents are observed. Once rodent nesting and feeding locations are determined, intercept their runways with a fresh, constant supply of rodenticide. An advantage of soft bait is its flexibility to place and secure it in hard to reach areas like wall voids or skewer the soft bait on a wire or zip tie between floor slats or on attic rafters. Always read and follow label directions. &nbsp;</p> <p style="text-align: justify;"><img class="aligncenter size-full wp-image-3066" src="/images/uploaded/wp-content/uploads/2017/08/Cannon-on-Zip-Tie-770-px-x-400-e1503687345251.jpg" alt="Cannon on Zip-Tie 770 px x 400" width="650" height="338" style="display: block; margin-left: auto; margin-right: auto;" /></p> <p style="text-align: justify;">Step 3: <strong>Consistency.</strong> Frequently inspect bait placements and replenish bait at sites where there is evidence of heavy feeding or evidence signs of rodent activity. Immediately replace spoiled or contaminated baits along with frequently cleaning out bait stations. Remember, rodent control is not a seasonal battle; it is a year-round war. Maintaining a consistent rodenticide rotation program helps to assure the rodent population remains resistance free in a production facility.</p> <p style="text-align: justify;">Click for more information <a href="http://www.hogslat.com/rat-mouse-baits-liphatech-motomco">Liphatech</a> &nbsp;</p>urn:store:1:blog:post:152https://hogslat.com/sow-group-housing-update-stanchionsSow group housing update | stanchions<p style="text-align: justify;">&nbsp; <img class="aligncenter size-large wp-image-3037" src="/images/uploaded/wp-content/uploads/2017/07/stanchion-1540x800-1024x532.jpg" alt="stanchion-1540x800" width="690" height="358" style="display: block; margin-left: auto; margin-right: auto;" /> <strong></strong></p> <p style="text-align: justify;"><strong>Group housing for sows remained a popular topic at this year&rsquo;s World Pork Expo. Hog Slat's sales director, Fritz Richards, outlines his recommendations for stanchions.</strong> <strong>&nbsp;</strong></p> <p style="text-align: justify;"><strong><em>What is the most common question asked about stanchions?</em></strong> <strong>&nbsp;</strong> <br /><strong>Probably the most common question is whether to use a solid or open style stanchion. We have not seen any difference in performance or sows' behavior whether the divider panel is solid or open. The advantages of an open rodded stanchion system are:</strong></p> <ul style="text-align: justify;"> <li><strong>Better ventilation due to not blocking air movement with a solid panel.</strong></li> <li><strong>Improved visibility of workers to observe sows</strong></li> <li><strong>Lower cost</strong></li> <li><strong>Longer life of equipment</strong></li> </ul> <p style="text-align: justify;">&nbsp; <img class="aligncenter size-full wp-image-3038" src="/images/uploaded/wp-content/uploads/2017/07/Dividers-770x400-e1501001893217.jpg" alt="Dividers-770x400" width="650" height="338" style="display: block; margin-left: auto; margin-right: auto;" /><strong></strong></p> <p style="text-align: justify;"><strong>We also have not observed less fighting or movement at feeding time if the divider is solid. All of our knowledge has come from working with our customers around the world where we have supplied stanchion equipment for over 750,000 sow places. </strong> <strong>&nbsp;</strong></p> <p style="text-align: justify;"><strong><br /></strong></p> <p style="text-align: justify;"><strong><em>What do you recommend for the length and width of the stanchion? </em></strong> <strong>&nbsp;</strong> <br /><strong>Most of the systems we have installed use an 18" to 22" wide stall with a 19" long divider to protect the sow's shoulder and head during feeding. </strong> <strong>&nbsp;</strong></p> <p style="text-align: justify;"><strong>Several years ago we experimented with different lengths of dividers and found there really wasn't much difference in sow behavior until we reached 36" in length. What we did notice is that when we increased the stall length to 48" the sows started using the stalls as a resting area instead of just using them at feeding. </strong> &nbsp;</p> <p style="text-align: justify;"><strong><img class="aligncenter size-full wp-image-3039" src="/images/uploaded/wp-content/uploads/2017/07/Stachions_long-770x400-e1501001948345.jpg" alt="Stachions_long-770x400" width="650" height="338" style="display: block; margin-left: auto; margin-right: auto;" /></strong><strong>The longer stalls allowed the more timid sows in the pen a "safe haven" where they could go to get away from the more aggressive animals. But at the same time, their movement isn't restricted, and they can freely go in and out of the stall. </strong> &nbsp; &nbsp;</p> <p style="text-align: justify;"><strong><em>Does anything else change when the divider is lengthened? </em></strong> <strong>&nbsp;</strong> <br /><strong>Yes, we also spread the width out to 23"-24&rdquo;. Since the stanchion was also being utilized as a resting area, we needed to provide the sows enough room to lie comfortably. Also, the pen size increased because it was necessary to allow at least seven feet between the end of the stanchion and the rear pen panel. &nbsp;This width avoids having a boss sow from lying across the pen and preventing the other sows from moving around freely. </strong> <strong>&nbsp;</strong></p> <p style="text-align: justify;"><strong></strong> &nbsp; <img class="aligncenter size-full wp-image-3040" src="/images/uploaded/wp-content/uploads/2017/07/Stanchion-group-770x400-e1501002056636.jpg" alt="Stanchion-group-770x400" width="650" height="338" style="display: block; margin-left: auto; margin-right: auto;" /><strong><em></em></strong></p> <p style="text-align: justify;"><strong><em>That is the optimum number of head per pen?</em></strong> <strong>&nbsp;</strong> <br /><strong>In the beginning, we started with large pens, 50+ head, but we quickly discovered that the optimum number is 8-12 head per pen.</strong> <strong>&nbsp;</strong></p> <p style="text-align: justify;"><strong>Stanchions continue to be the most <span style="text-decoration: line-through;">a</span> popular choice for many producers as they have proven to be consistent and reliable.

This traditionally includes cleaning the facility from top to bottom and applying a disinfectant. Any routine maintenance is performed, and those nagging issues that may have been noticed, but there wasn&rsquo;t enough time for during production to fix, finally get the attention they need. One part of the operation that is often overlooked, however, is the water line. Sure, any stuck or leaky drinker nipples may be serviced or replaced, but by and large drinker lines are shut off and forgotten about until the pigs come back into the barn.</p> <p style="text-align: justify;"><img class="aligncenter size-full wp-image-3031" src="/images/uploaded/wp-content/uploads/2017/07/waterline_770x400-e1501001232935.jpg" alt="waterline_770x400" width="650" height="338" style="display: block; margin-left: auto; margin-right: auto;" /></p> <p style="text-align: justify;">During this time the water line, while appearing benign on the outside, maybe even clean if the cleaning crew hit it with the pressure washer and disinfectant, is very much alive. Any leftover solids from the previous turn are settling inside the line from lack of flow. The biology present from the environment is multiplying, and any build up inside the lines is compacting into a concrete like substance. For all intents and purposes, the water line becomes an incubator while the pigs are out of the barn, especially when the barn is heated back up for repopulation. This, in turn, creates an interesting issue when the freshly weaned pigs take a drink from the line. The first drink a young pig gets is the worst drink it will get. It has the most biology, it is the warmest, oldest, and traditionally worst smelling/tasting water it will be exposed to in its life.</p> <p style="text-align: justify;">This is where terminal line disinfection comes in. Terminal line cleaning and disinfection occurs when the pigs are removed from the facility and line disinfectants can be applied to remove solids and eliminate any biology that is harbored in the lines. Aside from the obvious removal of pathogens, terminal line disinfection also improves the operation of the drinkers and increases the volume the line carries. The volume increase is especially important as we try to grow larger and larger finishing hogs with the same drinkers and drinker lines designed for market weight hogs 20% smaller.</p> <p style="text-align: justify;">The available data reflects this as well. Terminal line cleaning alone improved production at the research site as follows:</p> <p style="text-align: justify;"><img class="aligncenter size-full wp-image-3032" src="/images/uploaded/wp-content/uploads/2017/07/Chart_770x400-e1501001290304.jpg" alt="Chart_770x400" width="650" height="338" style="display: block; margin-left: auto; margin-right: auto;" /></p> <p style="text-align: justify;">6-week wean-nursery trial &ndash; Lines cleaned and disinfected with Peraside (Peracetic Acid Disinfectant, Neogen Corp.) &nbsp;</p> <p style="text-align: justify;">Terminal line disinfection in this research trial was achieved with a 3% solution of disinfectant administered into the lines with a sump pump upon depopulation. The solution sat in the lines overnight and was flushed the next morning with fresh water. All the nipple drinkers were triggered to ensure proper function and the pigs were placed. The product can also be injected with a mixing station like the Dosatron Venturi Pump <a href="https://goo.gl/TMNt1j">(DSA-Venturi)</a> with the yellow metering tip installed.</p> <p style="text-align: justify;"><img class="aligncenter size-full wp-image-3033" src="/images/uploaded/wp-content/uploads/2017/07/DSA-Venturi-e1501001358798.jpg" alt="DSA-Venturi" width="650" height="338" style="display: block; margin-left: auto; margin-right: auto;" /></p> <p style="text-align: justify;">This is similar to soap injector on a power washer and can be used in place of the normal medicator. The producer places the tube directly into the terminal line disinfectant and fills the lines and triggers the drinkers to ensure the product flows through all the parts of the drinker system. After allowing the solution to sit overnight, the producer then flushes the lines and triggers the drinkers again.</p> <p style="text-align: justify;">With a little effort, large production changes can be made, and the pigs no longer get the worst drink as their first drink.</p> <p style="text-align: justify;">Jesse McCoy, CWS, Business Unit Specialist, Water Treatment, Neogen Corp. &nbsp;</p>urn:store:1:blog:post:150https://hogslat.com/airstorm-x-brace-fans-feature-farm-smart-designAirStorm X-Brace fans feature “Farm Smart” Design<p style="text-align: justify;">&nbsp; <img class="aligncenter size-full wp-image-3024" src="/images/uploaded/wp-content/uploads/2017/07/57-57-feature-e1500997728729.jpg" alt="57&amp;-57-feature" width="650" height="338" style="display: block; margin-left: auto; margin-right: auto;" /></p> <p style="text-align: justify;">"These are the type of ventilation fans a poultry or hog producer would design to use on their own farms," exclaimed Hog Slat engineer Tyler Marion.

Knowing what to ask the potential contractors bidding on your project helps you avoid additional costs when or if problems occur during construction. &nbsp;</p> <p style="text-align: justify;"><img class="aligncenter size-full wp-image-3000" src="/images/uploaded/wp-content/uploads/2017/06/Money-stack-e1498501683359.jpg" alt="Money-stack" width="650" height="338" style="display: block; margin-left: auto; margin-right: auto;" /></p> <p style="text-align: justify;">1) Financial Strength.</p> <p style="text-align: justify;">A typical production site will cost from $350,000 upwards to $2,000,000 or more. For a project costing one million dollars, the builder will need to have the financial resources capable of paying for $500,000 of materials and labor. Also, most contractors will have several projects in varying stages of construction, meaning a typical builder may need a line of credit of several million dollars.&nbsp;&nbsp;</p> <p style="text-align: justify;">To protect your investment ask the contractor for a copy of their latest balance sheet to assess whether the contractor net worth is adequate for the project. If the builder is uncomfortable providing that type of information to you, require them to provide a payment and performance bond from a reputable insurer. Always consult your lender to determine if they are comfortable with the contractor&rsquo;s financial condition.</p> <p style="text-align: justify;"><img class="aligncenter size-full wp-image-3001" src="/images/uploaded/wp-content/uploads/2017/06/Swinging-Trusses-e1498501732686.jpg" alt="Swinging-Trusses" width="650" height="338" style="display: block; margin-left: auto; margin-right: auto;" /></p> <p style="text-align: justify;">2) Builders Risk and Workers&rsquo; Comp.</p> <p style="text-align: justify;">Unless required by the lender many contractors do not include builders risk insurance as part of their contract. Without this coverage, the owner is liable for any damages to the structure or building materials during the construction process. &nbsp;</p> <p style="text-align: justify;">The amount of Workers&rsquo; Compensation insurance a contractor is required to carry varies from state to state. The main provisions of this insurance should include coverage for any subcontractors working on the project, and this coverage is enforceable in the state where the work is performed. It is not uncommon for contractor or subcontractor's policy to only apply to their home state. &nbsp;</p> <p style="text-align: justify;">You should insist any potential contractor provide you with a Certificate of Insurance indicating builders risk coverage for the amount of the contract along with general liability insurance of at least $2 million per occurrence and also listing the states covered by the agreement. You as the building owner may also want to be listed as an additional insured on the policy, so you have the ability to make claims on the policy if the contractor will not. Consider raising the general liability amount to $5-10 million on sow farms and remodel projects as substantial damage can result from work performed on operational farms.</p> <p style="text-align: justify;"><img class="aligncenter size-full wp-image-3002" src="/images/uploaded/wp-content/uploads/2017/06/setting-bin-e1498501787527.jpg" alt="setting-bin" width="650" height="338" style="display: block; margin-left: auto; margin-right: auto;" /></p> <p style="text-align: justify;">3) Site Supervision</p> <p style="text-align: justify;">Adequate site supervision is subject to broad interpretation that varies by each contractor. Unless it is a complicated remodel or very large project, it is unreasonable to expect a job supervisor to be on site every day during the construction process. You should, however, expect the job supervisor to schedule frequent meetings with you to review and inspect the work in progress. Also be aware that many contracts do not provide for unloading trucks, dumpster rental, portable restrooms, and site cleanup. Failing to add these items in writing to the contract may cost you thousands in additional out of pocket costs. &nbsp;</p> <p style="text-align: justify;">4) Production Equipment</p> <p style="text-align: justify;">When faced with competitive bidding situations one of the methods used by contractors to reduce their price is to change the equipment supplied in the package. It is common for equipment manufacturers to offer special pricing to area builders during an expansion phase. This usually results in the poor installation of unfamiliar feeding, watering and ventilation equipment along with dubious warranty claims later. Ask the contractor to provide you with a list of completed projects with the same brands of equipment specified in the contract.</p> <p style="text-align: justify;">Protect your investment by requiring bidders on your project to provide you with the correct documentation. This allows you to limit your exposure to financial risk during and after the construction process. &nbsp; &nbsp; &nbsp; &nbsp; &nbsp;</p>urn:store:1:blog:post:148https://hogslat.com/farmstead-nests-featured-in-martha-stewart-blogFarmstead Nests Featured in Martha Stewart Blog<p>Martha Stewart recently installed new Farmstead nests on her farm near Bedford, New York. &nbsp; The farm houses over 100 chickens in four individual coops. &nbsp;Here's a short excerpt from the article: &nbsp;</p> <p><strong><em>I love knowing my hens are provided with clean, comfortable nests.

What makes AgriShift<sup>&reg;</sup> Dim-to-Blue<sup>&reg; </sup>technology uniquely beneficial, is that it is designed to influence and direct certain processes, recreating the best possible environment for your animal. New developments in LED lighting can now provide a customized light spectrum, intensity and photoperiod control for broiler environments. The utilization of this advanced LED lighting in broiler facilities can bring performance benefits, resulting in increased broiler production and improved animal welfare.&nbsp;</p> <p style="text-align: justify;">Three characteristics of lighting should be considered when designing a lighting system:</p> <p style="text-align: justify;">1) light spectrum or color of the light</p> <p style="text-align: justify;">2) intensity of the light, and</p> <p style="text-align: justify;">3) photoperiod or the amount of time the lighting fixtures are on each day.</p> <p style="text-align: justify;">In the past, lighting systems (incandescent, fluorescent or high-pressure sodium lamps) had fixed color and intensity, with the only controllable variable being the length of exposure. With ONCE<sup>&reg;</sup> AgriShift<sup>&reg;</sup> Dim-to-Blue<sup>&reg;</sup> technology and lighting systems, it is possible to control all three key characteristics. &nbsp;</p> <p style="text-align: justify;"><img class="aligncenter size-full wp-image-2940" src="/images/uploaded/wp-content/uploads/2017/04/Human_Poultry-Vision-e1495812017753.jpg" alt="Human_Poultry-Vision" width="770" height="400" style="display: block; margin-left: auto; margin-right: auto;" /></p> <p style="text-align: justify;">Research shows that a typical chicken views a light source much differently than a human eye would. For instance, the graphs below show that humans and chickens perceive green light similarly, but chickens have enhanced sensitivity to reds, blues and ultraviolet light. Additional research has shown that different wavelengths can be used to enhance various aspects of development. For example, green light increases growth during the early stages of development by enhancing proliferation of skeletal muscle satellite cells, which repair and build muscle. Blue light is helpful in the growth and sexual development of poultry at a later age by elevation of plasma androgens, allowing the bird to put on more muscle mass. Combined green and blue light promotes myofiber growth due to more effective stimulation of testosterone secretion. <strong>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; </strong></p> <p style="text-align: justify;"><strong></strong> By organizing individual LEDs to activate at predetermined voltage levels, it is feasible to implement a color-shifting technology, which is the foundation of AgriShift<sup>&reg; </sup>Dim-to-Blue<sup>&reg; </sup>lighting products for broilers<img class="aligncenter wp-image-2941 size-full" src="/images/uploaded/wp-content/uploads/2017/04/AfgriShift-range-e1493148426385.jpg" alt="AfgriShift-range" width="770" height="400" style="display: block; margin-left: auto; margin-right: auto;" /></p> <p style="text-align: justify;">AgriShift<sup>&reg; </sup>Dim-to-Blue<sup>&reg; </sup>lighting systems shift the spectrum to mimic a natural sunrise and sunset. With no dimming, the system produces a full light spectrum, ideal for stimulating growth when beginning a chicks growth cycle. As grow out continues the lighting is gradually decreased to 30%, shifting the range from blue to green to promote muscle growth. When the system is fully dimmed (also known as moon lighting), the monochromatic blue is used to calm the birds at night or before catching. &nbsp;</p> <p style="text-align: justify;">Using ONCE<sup>&reg;</sup> AgriShift<sup>&reg; </sup>Dim-to-Blue<sup>&reg; </sup>technology and lighting systems allow broiler farmers an environmentally friendly lighting option that not only saves on electrical costs but also improves animal welfare and increases broiler production.</p> <p style="text-align: justify;">To learn more click<a href="http://hogslat.com/once-agrishift-mlb-10w-led-fixture-for-poultry-broilers-turkeys"> Dim-to-Blue&reg;</a>.</p>urn:store:1:blog:post:145https://hogslat.com/static-pressure-key-to-troubleshooting-ventilationStatic Pressure Key to Troubleshooting Ventilation<p><img class="aligncenter size-full wp-image-2963" src="/images/uploaded/wp-content/uploads/2017/05/Ice-Chicken-web-e1494972251237.jpg" alt="Ice-Chicken-web" width="600" height="312" style="display: block; margin-left: auto; margin-right: auto;" /></p> <p>With the summer heat settling in it's not uncommon for ventilation problems to start showing up in broiler houses and swine gestation/ breeding buildings. Even facilities that have performed well in the past may experience issues.&nbsp;&nbsp; One of the best yardsticks for evaluating a ventilation system is measuring wind speed. Windmeters ranging from an <a href="http://hogslat.com/weatherflow-wind-meter">inexpensive smartphone</a> unit to dedicated <a href="http://hogslat.com/4-in-1-digital-environment-tester">handheld devices</a> are used to measure wind speed in feet per minute. &nbsp;</p> <p>If the wind speed is lower than desired the next step is to check the static pressure with either a portable manometer or on the ventilation control monitor.&nbsp;&nbsp; With the ventilation system operating at full capacity, the house pressure should be between .05 to .08". Some broiler facilities will experience higher pressure due to increased air requirements.</p> <p>If the static pressure is high, the most likely cause is restricted airflow through cool cell pads clogged with scale or algae.</p> <p><img class="aligncenter size-full wp-image-2952" src="/images/uploaded/wp-content/uploads/2017/05/Scale_Algae_Cool-Cell-e1494971882662.jpg" alt="Scale_Algae_Cool-Cell" width="600" height="312" style="display: block; margin-left: auto; margin-right: auto;" /></p> <p>Scale is the buildup of minerals hard water leaves behind as it evaporates during the cooling process. Heavy deposits of scale require the use of a broom to dislodge the debris and then rinsing them off the pad with a low-pressure hose nozzle. The best way to deal with scale is to prevent it from forming in the first place. Adding a <a href="http://hogslat.com/cool-cell-cleaner-descaler-powder-8-lb">descaler treatment</a> to the water helps keep the minerals in suspension and prevents them from sticking to the pad. &nbsp;</p> <p>Nutrients in the water allow algae to grow and block the openings in the pad. Adding algaecides to the recirculating water kills the algae and prevents it from re-establishing. Allowing the pad to dry completely for several hours each day also stops algae growth. <img class="aligncenter size-full wp-image-2953" src="/images/uploaded/wp-content/uploads/2017/05/Dirty-Cool-Cell-Trough1-e1494967506629.jpg" alt="Dirty-Cool-Cell-Trough" width="600" height="312" style="display: block; margin-left: auto; margin-right: auto;" /></p> <p>But by far the most important management practice for cool cell maintenance is to drain and replace the water often. Even with the use of chemical agents, a build up of contaminants occurs in the trough. How often to replace the water depends on water quality and the amount of the time the system operates each day. Once a month is an absolute minimum during periods of heavy use to flush grit and dirt from the system.</p> <p><img class="aligncenter size-full wp-image-2954" src="/images/uploaded/wp-content/uploads/2017/05/Fan-Belts-770x400-e1494968037924.jpg" alt="Fan-Belts-770x400" width="600" height="312" style="display: block; margin-left: auto; margin-right: auto;" /></p> <p>If the static pressure is too low, the first reaction is to add fans to increase airflow.&nbsp;&nbsp; In many cases, especially in buildings where the airflow seemed adequate before, replacing the fan belts and/or pulleys will restore proper air flow.&nbsp;&nbsp; Slippage caused by worn belts and pulley cause fans to be less efficient and air delivery to suffer by as much as 20%. Plan to replace all <a href="http://hogslat.com/fan-v-belts-grobelt-drive-belts">fan belts</a> on an annual basis with the metal pulleys needing replacement about every four years.&nbsp;&nbsp; A visual check after installing new belt should show the belt riding high in the pulley groove. If the belt sinks into the groove, then the pulley should be replaced. &nbsp;</p> <p>Routine, scheduled maintenance on fans and evaporative systems is fundamental to providing broilers and pigs with adequate cooling during hot weather extremes. &nbsp;</p> <p>By Austin Baker<br />Ventilation Director<br />Hog Slat Inc.&nbsp; &nbsp; &nbsp;&nbsp;</p>urn:store:1:blog:post:146https://hogslat.com/slat-design-aids-pig-welfareSlat Design Aids Pig Welfare<p style="text-align: justify;">&nbsp; <img class="aligncenter size-large wp-image-2971" src="/images/uploaded/wp-content/uploads/2017/05/Pig-Slats-1540x800-1024x532.jpg" alt="Pig-Slats-1540x800" width="690" height="358" style="display: block; margin-left: auto; margin-right: auto;" /></p> <p style="text-align: justify;">Inappropriate or poorly maintained slatted floors are the most common causes of physical injuries to pigs. Pigs with foot or joint pain will not get up as often to eat and drink resulting in lower Average Daily Gain and reduced performance.&nbsp;&nbsp; The industry movement to group gestation housing also means better flooring is necessary to prevent injuries to heavy sows in open pens.&nbsp;&nbsp; By some estimates, lame sows can cost producers from $180 -$400 for each animal suffering from foot-related problems. &nbsp;</p> <p style="text-align: justify;">Well designed slats promoting good animal welfare possess several common characteristics. They are manufactured from high-density concrete, have a level, flat top for ease of walking and a uniform slat opening.</p> <p style="text-align: justify;"><img class="aligncenter wp-image-2972 size-full" src="/images/uploaded/wp-content/uploads/2017/05/slump-cones-e1495808792147.jpg" alt="" width="600" height="312" style="display: block; margin-left: auto; margin-right: auto;" /></p> <p style="text-align: justify;">Manufacturing high quality begins with the slump of concrete. The less water added to the concrete, the stronger the slat. Dry-cast concrete, having a zero slump, only uses enough water to begin the chemical reaction.&nbsp;&nbsp; When excess water is added to make the concrete easier to form, the excess moisture evaporates; creating pores in the concrete and reduces its strength and durability. The lower cement-water ratio in dry cast slats yields a finished product with higher strength and durability with fewer repairs needed over its useful life. &nbsp;</p> <p style="text-align: justify;">Dry cast, machine-finished slat production requires fewer molds than comparable wet cast, hand-finished slats. Fewer molds mean less variation and a more consistent final product with a flat, level top and uniform slat openings. <img class="aligncenter size-full wp-image-2973" src="/images/uploaded/wp-content/uploads/2017/05/MachinedSlats-e1495808870249.jpg" alt="MachinedSlats" width="600" height="312" style="display: block; margin-left: auto; margin-right: auto;" />The level surface provided by flat top slats reduces joint injuries from twisting and slipping on uncomfortable floors. Uniform slat openings prevent the pigs' legs from getting caught in a narrowing opening and damaging their toes and claws. &nbsp; Keep slats in good condition by using quick setting, abrasion resistant mortars to repair any exposed aggregates as normal wear occurs. Cover surfaces around feeders and waterers with an epoxy overlay coating to protect the concrete from acid compounds and heavy pig traffic.

"Evaporative cooling is really a pretty simple concept, but you have to perform basic maintenance tasks to keep the system operating correctly." &nbsp; &nbsp;</p> <p style="text-align: justify;"><strong>Flush, Don't Bleed<br /></strong>A standard industry practice involves "bleeding-off" a percentage of the recirculation water to prevent a buildup of scale on the pads. Scale is the mineral deposit left on the pad when the water evaporates. While bleeding-off is better than nothing, a much better practice is to dump all the water from the trough and replenish with fresh water that in turn helps to flush the containments out of the cool cell pads. How often the trough needs to be drained depends on the hardness of the water and how often the evaporative system operates. Monitoring the PH level is a useful method to determine when to change the water with readings above 8.5 indicating an excessive mineral buildup.</p> <p style="text-align: justify;"><img class="aligncenter wp-image-2978 size-full" src="/images/uploaded/wp-content/uploads/2017/05/Scale_Algae-e1495809410356.jpg" alt="" width="600" height="312" style="display: block; margin-left: auto; margin-right: auto;" /> <strong></strong></p> <p style="text-align: justify;"><strong>Use Preventive Chemical Treatments. <br /></strong> Paired with frequent water flushing, adding descalers and microbicides to the recirculating water pays big dividends in extending pad life. Descalers help keep minerals in suspension for more efficient flushing while microbicides reduce the growth and buildup of algae, bacterial and fungal slimes on the pads.&nbsp;&nbsp; Never use chlorine bleaches to kill algae. Chlorine attacks the glue in the pads causing delamination.</p> <p style="text-align: justify;"><img class="aligncenter size-full wp-image-2979" src="/images/uploaded/wp-content/uploads/2017/05/Soggy-pad770x400-e1495809555816.jpg" alt="Soggy-pad770x400" width="600" height="312" style="display: block; margin-left: auto; margin-right: auto;" /> <strong></strong></p> <p style="text-align: justify;"><strong>Adjust the Float.</strong> <br />One of the most common reasons for premature failure occurs when water logged pad bottoms become soft and sag down.&nbsp;&nbsp; Just because water doesn't spill out of the trough when the system shuts down doesn't mean the float is adjusted correctly. When properly set the water level should be 1" below the bottom of the pads. It is critical to check the water level in new installations after running the system for several days.</p> <p style="text-align: justify;">Be on the lookout for trough levelness to change as the building settles and the framing shifts. Also, as the pads age, they retain more water making float valve adjustments necessary. &nbsp;</p> <p style="text-align: justify;"><strong>Clean the Trash Out <br /></strong> Trash and debris in the pump trap and water line filters reduce the amount of water circulating through the system. A telltale sign of reduced water flow is dry or streaked pads at the end opposite of the pump. Failing to remove debris from the trash basket on a jet pump also reduces its useful life. Clean the holes in the distribution pipe whenever dry streaks appear on the pad. Open the ball valve on distribution pipe opposite the pump end and run the system to flush out any gunk from inside the pipe at least once a month. &nbsp;</p> <p style="text-align: justify;"><strong>Winterize the System. <br /></strong> Shutting off the water supply and draining the system are the basics for preparing an evaporative system for winter. In addition, remove the pump from the system and move it to inside storage. Just disconnecting the plumbing fittings and leaving the pump in place leads to damaged impellers and cracked housings. &nbsp;</p> <p style="text-align: justify;">Performing basic maintenance allows evaporative cooling systems to operate efficiently and delays costly pad replacement.&nbsp; &nbsp; &nbsp; &nbsp; &nbsp;&nbsp;</p>urn:store:1:blog:post:142https://hogslat.com/effect-of-an-additional-waterer-on-growth-performance-of-nursery-pigsEffect of an additional waterer on growth performance of nursery pigs<h4 style="text-align: justify;">EXECUTIVE SUMMARY</h4> <p style="text-align: justify;">The key objective of this study was to determine the effect of additional access to water on nursery pig performance over a 28-day period. A total of 2,017 weanling nursery pigs were allotted to one of two treatment groups: Control (SC): Dual Standard Cup Waterers; or Test (WC): Additional, 4 Nipple Horizontal Water Bar. Pigs were fed according to the standard, three phase feeding program in place in this commercial unit, and were offered ad libitum access to water and feed throughout the trial. Providing additional access to water with the water bar incrementally increased water disappearance by 0.03 gal/pig. In addition, a positive response in average daily feed delivered (ADFD) was observed in Periods 1 and 3 (14.8% and 9.2% higher, respectively, P&lt;0.05); and 5.2% overall (P&lt;.10) for WB versus SC pigs.&nbsp;&nbsp; Moreover, ADG was 8.8% greater for WB versus SC pigs in Period 3. Overall, this study provides evidence that the provision of an extra water bar in the nursery phase can translate into 1.4 lbs more feed delivered per pig resulting in 1.1 lbs more gain per pig in 28 days.</p> <p style="text-align: justify;"><strong>OBJECTIVE</strong> <br />Given the well-documented correlation of feed and water intake, the objective of this trial was to determine if the provision of additional access to water would promote higher water consumption, and concomitant growth performance in weanling nursery pigs reared in a commercial environment over a 28-d period. &nbsp;</p> <p style="text-align: justify;"><strong>METHODS</strong> <br />Pigs (n=2017) were mixed-sex housed in a single room within in a 4-room, commercial wean-to-finish barn, with a shared feeder between adjacent pens. Pigs were equally allotted to 42 pens to yield a stocking density of 48 pigs/pen (144 sq. ft./pen) Pens were allotted to one of two treatment groups as follows: Control (<strong>SC</strong>): <strong>S</strong>tandard <strong>C</strong>up waterers with 2 per pen located on the right and left sides of each pen, or; Treatment (<strong>WB</strong>): Control + an additional horizontal, 4-nipple <a href="http://hogslat.com/nipple-bar-with-8-nursery-nipples-4"><strong>W</strong>ater <strong>B</strong>ar</a> . &nbsp;</p> <p style="text-align: justify;">Pigs were fed according to the standard, three phase nursery program routinely utilized in this commercial facility, and had ad-libitum access to feed and water throughout the 28-day trial. Water disappearance for the SC and WB groups was monitored via individual mainline water meters supplying water to the standard right and left-side waterers, and the additional water bar. &nbsp;</p> <p style="text-align: justify;">Pen weights were monitored at the initiation of the study (Day 0) and thereafter at 7, 14 and 28 days. Feed intake was monitored by total feed delivered to each shared pen. All mortalities and removals over the course of the trial were also recorded. &nbsp;</p> <p style="text-align: justify;"><strong>RESULTS</strong> <br />Table 1 shows the summary of water disappearance as measured by metered gallons of water. Observationally, the addition of the extra water bar increased water disappearance by 0.03 gal/pig/day or 17.6%. It was noted, however, that the overall consumption of water (as measured by water disappearance) was generally lower that expected for pigs of this age. In general, literature reports indicate nursery pigs typically consume 0.3 gal of water/lb of feed consumed. &nbsp;</p> <p style="text-align: justify;">Table 2 provides a summary of performance. A positive response in average daily feed delivered (ADFD) was noted in Periods 1 and 3 (14.8%, 9.2% higher, respectively, P&lt;0.05); and 5.2% overall (P&lt;.10) for WB pigs. This increase in ADFD translated into 8.8% higher ADG for WB pigs in Period 3, however no other improvements in ADG or G/ADFD were noted within the three periods or overall.</p> <p style="text-align: justify;"><img class="aligncenter wp-image-2927 size-large" src="/images/uploaded/wp-content/uploads/2017/04/Screen-Shot-2017-04-24-at-9.48.22-AM-e1493042757880-1024x330.jpg" alt="Table 1" width="690" height="222" style="display: block; margin-left: auto; margin-right: auto;" /> <img class="aligncenter wp-image-2928 size-full" src="/images/uploaded/wp-content/uploads/2017/04/Screen-Shot-2017-04-24-at-9.48.45-AM-e1493042777571.jpg" alt="Table 2" width="760" height="628" style="display: block; margin-left: auto; margin-right: auto;" /><strong>Conclusion &amp; Recommendations<br /></strong>This study provides initial evidence that the overlay of a 4-nipple water bar to the standard dual cup waterer system to provide additional access to water, and promote increased water consumption has measurable impact on improved feed intake (as measured by total feed delivered). &nbsp;</p> <p style="text-align: justify;">Given the potential performance impact of improved feed intake together with the preliminary results of this trial, it is recommended that the study be repeated with the following modifications in order to more accurately assess the effect of increased access to water:</p> <ul> <li style="text-align: justify;">Addition of feed weigh backs to the protocol to improve accuracy in feed intake monitoring.</li> <li style="text-align: justify;">Collection of water disappearance data throughout the full study period.</li> <li style="text-align: justify;">Consideration of calibration or replacement of water meters to improve accuracy of water disappearance monitoring.</li> <li style="text-align: justify;">Randomization of the test variable (water bar) throughout the room to help better account for water line distances.</li> <li style="text-align: justify;">Verification and standardization of waterer flow pressure to recommended levels for nursery pigs (8 fl.

Because the load cells were expensive, many systems were set up with load cells on half of the bin legs, or they used I-beams to span between two legs.&nbsp;&nbsp; Inaccurate readings resulted when feed bridging caused one side of the bin to feed out faster than the other side.&nbsp;&nbsp; At best, these early systems were 80% accurate and really were more of an expensive early warning system for feed outages than a serious feed management tool. &nbsp;</p> <p style="text-align: justify;">The current generation of bin weighting systems gives producers the tools for accurate feed management.</p> <p style="text-align: justify;"><img class="aligncenter wp-image-2897 size-full" src="/images/uploaded/wp-content/uploads/2017/03/BinTracDiagram770x400-e1490701375223.jpg" alt="BinTracDiagram770x400" width="600" height="312" style="display: block; margin-left: auto; margin-right: auto;" /><a href="http://www.hogslat.com/bintrac-feed-bin-weighing-system"></a></p> <p style="text-align: justify;"><a href="http://www.hogslat.com/bintrac-feed-bin-weighing-system">BinTrac&reg;</a> offers a dedicated bin weighing system with a unique load cell assembly in which the bracket functions as the lifting mechanism.&nbsp;&nbsp; This type of bracket assembly requires less than 1/2" of lift to install, requires no shimming or blocking and can be installed on existing and loaded bins. &nbsp;</p> <p style="text-align: justify;">On each bin, the smart summing box gathers input from each load cell and sends it to the BinTrac Pro indicator control than can be located up to 250 feet from the bin. The BinTrac Pro Indicator displays information from up to four bins with a visual bar graph level indicator and digital readout of current weight, 24-hour feed usage, and recent fill weights. &nbsp;</p> <p style="text-align: center;"><img class="wp-image-2898 size-full" src="/images/uploaded/wp-content/uploads/2017/03/BinTrac_1_700x440-e1490701396142.jpg" alt="BinTrac_1_700x440" width="600" height="312" style="display: block; margin-left: auto; margin-right: auto;" /> <em>Load Cell and Summing Box mounted on a bin.

Options are also available to collect this data remotely via a wireless LAN system to record current inventories and monitor usage to predict and coordinate feed schedules. &nbsp; &nbsp; &nbsp;</p> <p style="text-align: justify;">The <a href="http://www.hogslat.com/maximus-system-controller">Maximus&reg;</a> control system provides accurate feed management as a function of their whole house controller. &nbsp;</p> <p style="text-align: justify;">Load cells mounted on bin legs send information to a junction box, which in turn transmits, to an individual relay box located inside the building. The relay boxes, representing each bin, are wired in series to the Maximus controller. &nbsp;</p> <p style="text-align: justify;"><img class="aligncenter wp-image-2902 size-full" src="/images/uploaded/wp-content/uploads/2017/03/Maximus-Screen-770x400-e1490701734209.jpg" alt="Maximus-Screen-770x400" width="600" height="312" style="display: block; margin-left: auto; margin-right: auto;" /></p> <p style="text-align: justify;">The Maximus controller logs and displays the primary data on a Bin Overview screen (Fig.1) showing Feed Remaining, Amount of Feed Consumed in the last 24 hours, and Feed Consumed per head.&nbsp;&nbsp; From there, the operator can drill down to an individual bin screen (Fig.2) to view greater detail. In this screen, the operator can also set various warning levels to trigger feed outage alarms by text or email. &nbsp;</p> <p style="text-align: justify;">A new product scheduled for release later this year is an automated feed slide that can be configured to close a slide as one bin empties and automatically open the slide on a second bin. Bin slides can also be remotely opened from inside a building, eliminating the need for a farm manager to go outside and risk compromising biosecurity. &nbsp;</p> <p style="text-align: justify;">Like all the functions controlled by the Maximus system, this feed data can be viewed and adjusted remotely from a smartphone, tablet or computer. The operator can also schedule personalized reports to be sent by email to other members of the production team.</p>urn:store:1:blog:post:141https://hogslat.com/ensure-farm-biosecurity-with-key-cardsEnsure Farm Biosecurity with Key Cards<p style="text-align: justify;">The introduction of a contagious disease to a farm represents a severe economic impact on a flock.</p> <img src="/images/uploaded/wp-content/uploads/2017/03/BioSecurity1540x800-e1490703789253.jpg" alt="BioSecurity1540x800" width="600" height="312" style="display: block; margin-left: auto; margin-right: auto;" /> <p style="text-align: justify;">Contaminated clothing, equipment, and footwear remain one of the primary causes of bird exposure to disease-causing organisms. Managing traffic should be a top priority on your farm to prevent the introduction of disease.</p> <p style="text-align: justify;">This advanced biosecurity system operates much like key cards utilized in hotels. Electronic door latches are installed on entrance doors or traffic gates and connected to a Maximus card reader. Presenting an authorized card activates the door lock solenoid. </p> <p style="text-align: center;"><img src="/images/uploaded/wp-content/uploads/2017/03/MaxScan770x400-e1490703810213.jpg" alt="MaxScan770x400" width="600" height="312" style="display: block; margin-left: auto; margin-right: auto;" /><em style="text-align: center;">Maximus scanner and ID card used at a farm entrance gate.</em><span style="text-align: center;">  </span></p> <p style="text-align: justify;">Each user is assigned a tag or card and completes their profile by adding an email or phone number. The type of access given to each card controls entry to production facilities; this can range from limited to full access. For example, you can grant permission for employees working a weekend shift access to the buildings only on Saturday and Sundays between 5 am to 2 pm.  </p> <p style="text-align: justify;">Every site or building has a designated health status. The owner operator then establishes a health protocol for personnel to follow. An example of a health protocol or rule would be to deny access to a "clean" site for 48 hours after visiting a "dirty" site.   Trying to enter a "clean" site before 48 hours results in denied entrance. The system sends an email or SMS, explaining the reason, to anyone denied access.  </p> <p style="text-align: justify;">Doors can be remotely unlocked to allow access to specific visitors, such as veterinarians and service techs that do not have a card.</p> <p style="text-align: center;"><img src="/images/uploaded/wp-content/uploads/2017/03/MaxBioScreen770x400-e1490703831517.jpg" alt="MaxBioScreen770x400" width="600" height="312" style="display: block; margin-left: auto; margin-right: auto;" /> <em>Screen showing the access history to the farm site.</em></p> <p style="text-align: justify;">The system also provides a history of the activity for all sites. After selecting the time range to view, the operator will see the username, the tag number, location of the reader used, the date/time reading of a card, the status (if the user was allowed access) and the reason for the denied access.  </p> <p style="text-align: justify;">The same card is also used to enable access to the Maximus house controller. For instance, a particular card may permit the user to view the screen but not make adjustments, while another level of permission might only allow a farm worker to enter the number of eggs collected or record the number of deads picked up.</p>urn:store:1:blog:post:140https://hogslat.com/dim-to-calmpig-lightingDim-To-Calm™Pig Lighting<p style="text-align: justify;"><img class="aligncenter wp-image-2906 size-full" src="/images/uploaded/wp-content/uploads/2017/03/DimtoCalm-1540x800-e1490702758515.jpg" alt="DimtoCalm 1540x800" width="600" height="312" style="display: block; margin-left: auto; margin-right: auto;" /></p> <p style="text-align: justify;">Using LED style lighting reduces electrical usage by 75-80% compared to incandescent bulbs and 50-60% over spiral CFLs. In most situations, the financial payback period will be between one to two years. &nbsp;</p> <p style="text-align: justify;">While all LED lights will achieve this expected energy savings, Once, Inc. offers their AgriShift Dim-to-Calm&trade; system specifically designed for use in swine facilities. &nbsp;</p> <p style="text-align: justify;">Domestic swine were developed from wild boar species, which occupy shaded habitats and are most active at dawn and dusk. This fact suggests that swine have a visual system that is best adapted to dim light rather than the bright light of mid-day or darkness of nocturnal light. &nbsp;</p> <p style="text-align: justify;">While humans see light primarily in the green and yellow spectrums, swine&rsquo;s highest sensitivity is focused on the blue and green parts of the scale with little recognition of red shades. In other words, pigs perceive red lighting as darkness.</p> <p style="text-align: center;"><img class="wp-image-2907 size-full" src="/images/uploaded/wp-content/uploads/2017/03/sunset-e1490702725634.jpg" alt="sunset" width="600" height="312" style="display: block; margin-left: auto; margin-right: auto;" /> <em>Dim-To-Calm lighting mimics sunrise to sunset photoperiods</em></p> <p style="text-align: justify;">Photoperiod requirements have not been well studied in swine, but it is evident a cyclical light: dark cycle should be provided. At all stages of production, swine benefit from at least eight hours of light and at least eight hours of darkness. The transition from light to dark periods should be gradual, much like natural sunrise and sunset, to reduce stress caused by sudden changes in light. &nbsp;</p> <p style="text-align: justify;">AgriShift Dim-to-Calm LED technology provides producers a method to automatically control light intensity, color spectrum and photoperiod length for swine specific lighting. The dimming capability simulates a sunrise to sunset scheme and is regulated through the house controller by use of a slave dimmer or by an AgriShift master control. Additionally, the shifted spectrum provides a service light (red color) that allows workers to have continual access to the facility after hours without disturbing or interrupting the sleep cycles of the pigs. Some producers have also utilized an additional period of light at night during hot weather. By setting up a shorter sunrise to sunset sequence during the cooler evening hours, they can encourage finishing pigs to consume more feed.</p> <p style="text-align: center;"><img class="wp-image-2908 size-full" src="/images/uploaded/wp-content/uploads/2017/03/AgriShift-products-e1490702704670.jpg" alt="Dim-To-Calm lighting mimics sunrise to sunset photoperiods" width="600" height="312" style="display: block; margin-left: auto; margin-right: auto;" /> <em>10 watt LED fixture with slave dimmer</em></p> <p style="text-align: justify;">The <a href="/agrishift-mlm-swine-10w-led-light-fixtures">AgriShift LED lights</a> are 10-watt jelly jar type fixtures with output equal to a 75-watt incandescent. It's an innovative design with the minimal heat of LEDs allowing the use of a low-profile plastic jar measuring only 2&rdquo; compared to a typical 5"-7" long jelly jar. Replacement is simple with the provided Edison pigtail connector screwing into the existing light socket, twisting the jelly jar adapter in place and connecting the base lamp to complete the installation. The expected life of the bulb is 50,000 hours and is backed by Once's 5-year replacement warranty. &nbsp;</p>urn:store:1:blog:post:138https://hogslat.com/click-clack-doesnt-mean-your-medicator-is-working“Click-Clack” Doesn’t Mean Your Medicator is Working.<p style="text-align: justify;"><img class="aligncenter wp-image-2887 size-large" src="/images/uploaded/wp-content/uploads/2017/03/Medicator1540X800-1024x532.jpg" alt="Medicator1540X800" width="690" height="358" style="display: block; margin-left: auto; margin-right: auto;" /></p> <p style="text-align: justify;">Many of the chemical products used in poultry and swine production are delivered through the water system.   Some simple best practices will keep your water-driven, volumetric proportioner, or as it more commonly called a medicator, in good working order.</p> <p style="text-align: justify;"><img class="aligncenter wp-image-2888 size-full" src="/images/uploaded/wp-content/uploads/2017/03/Agitator-Pump-e1490700076506.jpg" alt="Agitator-Pump" width="600" height="312" style="display: block; margin-left: auto; margin-right: auto;" /><strong>1.Use a mixing device in the stock tank...and that doesn't mean a paint stick!</strong>  <br />Many of these products don't mix well in stock tanks and are difficult to keep in suspension. A small (1/200 hp.) <a href="http://hogslat.com/little-giant-agitiator-pump-10-foot-cord">agitation pump</a> does a great job of keeping solids in suspension, is inexpensive to operate and is relatively low-cost at around $60. Maintaining a homogenous mixture in the chemical stock tanks aids in accurate chemical delivery.  </p> <p style="text-align: justify;"><strong>2.Flush with clean water...from a clean bucket.</strong>   <br />After you finish injecting a product, take the hose out of the stock tank and let the medicator pull water from a clean 5-gallon bucket. The fresh water will flush any chemical residue from the seals and springs. Cleaning the system also prevents any problems with leftover chemical reacting with the next product used in the system.   <img class="aligncenter wp-image-2889 size-full" src="/images/uploaded/wp-content/uploads/2017/03/Seal-Kits-e1490700105701.jpg" alt="Seal Kits" width="600" height="312" style="display: block; margin-left: auto; margin-right: auto;" /> <strong>3."Click-Clack" doesn't mean it's working... replace the seals.</strong>   <br />While it is easy to diagnose a broken spring or diaphragm when you don't hear the familiar "click-clack," a medicator will continue to operate with damaged seals. Harsh chemicals can weaken or damage the rubber seals over time, allowing the stock solution to leak causing inaccurate dosing rates.   To maintaining accurate chemical delivery, replace the rubber seals annually. There are replacement seals kits available for every brand of medicator on the market. It takes less than 15 minutes to do and the cost for most kits is under $20.</p> <p style="text-align: justify;"></p> <p style="text-align: justify;"><img src="/images/uploaded/Blog/Click Clack/Springs_900x450.jpg" alt="" width="900" height="450" /></p> <p style="text-align: justify;"></p> <p style="text-align: justify;"></p> <p style="text-align: justify;"></p> <p style="text-align: justify;"></p> <p style="text-align: justify;"><strong>While you're at it... clean the inside too.</strong> <br />As long as you are taking the medicator apart, disassemble the entire medicator as far as you feel comfortable doing and soak the parts in soapy water to remove chemical or mineral deposits.  Let the part soak for 24-48, rinse and reassemble.  To remove a heavy mineral buildup, consider using a 50% vinegar soultion or CLR to soak the parts.  Check with the equipment manufacturer before using.  </p> <p style="text-align: justify;"></p> <p style="text-align: justify;"><img class="aligncenter wp-image-2891 size-full" src="/images/uploaded/wp-content/uploads/2017/03/suction-hose-e1490700398826.jpg" alt="" width="600" height="400" style="display: block; margin-left: auto; margin-right: auto;" /><strong><br />5.Check the suction hose...it works like a straw.</strong> <br />A cracked or broken suction tube permits air to enter the system ruining accuracy. It's a good idea to periodically snip off the top part of the hose and reattach it to the medicator hose barb to prevent leaks.  </p> <p style="text-align: justify;">These are general recommendations for the most commonly used chemicals.   Some chemical formulations may require more frequent maintenance and cleaning of medicator pumps for proper dosing rates.</p>urn:store:1:blog:post:137https://hogslat.com/sprinkler-systems-enhance-tunnel-ventilationSprinkler Systems Enhance Tunnel Ventilation<p style="text-align: justify;"><img class="aligncenter size-large wp-image-2874" src="/images/uploaded/wp-content/uploads/2017/03/Ice-Cube-Chicken-1024x532.jpg" alt="Ice Cube Chicken" width="690" height="358" style="display: block; margin-left: auto; margin-right: auto;" /></p> <p style="text-align: justify;">A low-pressure sprinkler system should not be confused with the standard fogging systems. While fogging systems deliver a fine mist, low-pressure sprinklers produce a larger water droplet that does not hang in the air but drops straight to the floor. As the droplets hit the birds, they are stimulated to stand up and migrate to feed and water.</p> <p style="text-align: justify;">The settings in the controller can be configured to match any management scheme by varying the starting and ending set points for dates, times and temperatures in both cooling and activity modes. The following is an example of a typical operating sequence.&nbsp;</p> <p style="text-align: center;"><img class="wp-image-2869 size-full" src="/images/uploaded/wp-content/uploads/2017/03/Poultry-Cooling-System-770x400-e1488581548184.jpg" alt="Sprinkling encourages bird migration to feed and water" width="600" height="312" style="display: block; margin-left: auto; margin-right: auto;" /> <em>Sprinkling encourages bird migration to feed and water</em></p> <p style="text-align: justify;">As the building temperature increases and the building goes into tunnel mode, the sprinkler system begins to activate its first stage setting at 2 degrees above set point.&nbsp;&nbsp; The system runs for 10 seconds every 30 minutes. The birds react by standing and releasing the heat trapped under their bodies, which is removed by the ventilation system. &nbsp;</p> <p style="text-align: justify;">In the second stage, the sprinkler system increases output at five degrees above set point by operating for 20 seconds every 15 minutes. The trapped heat is released more often as the bird's activity increases and the additional sprinkling begins to create some evaporative cooling on the birds. &nbsp;</p> <p style="text-align: justify;">At eight degrees above tunnel mode, the sprinkler control enters into its third stage increasing to 20 seconds every seven minutes. Wind speed should be at least 600 feet per minute, creating wind chill and evaporative cooling on the birds minimizing any felt heat stress.</p> <p style="text-align: center;"><img class="wp-image-2871 size-full" src="/images/uploaded/wp-content/uploads/2017/03/GS-Sprinkler-control770x400_2-e1488581627893.jpg" alt="GrowerSELECT control with sprinkler head assemblies" width="600" height="312" style="display: block; margin-left: auto; margin-right: auto;" /> <em>GrowerSELECT control with sprinkler head assemblies</em></p> <p style="text-align: justify;">If outside temperatures continue to rise and the barn controller activates the evaporative cooling system, the sprinkler system will drop back to either stage two or three.&nbsp;&nbsp; The large water droplets hitting the birds continue to stimulate their activity, encouraging frequent migration to the feeders and waterers. &nbsp;</p> <p style="text-align: justify;">Increasing the evaporating cooling set point to 12 degrees above when the tunnel doors are activated may save up to 80% of the water normally used during the initial cooling stages. &nbsp;</p> <p style="text-align: justify;">The building is also operating at a low humidity level allowing the birds to more efficiently cool themselves through natural respiration. &nbsp;</p> <p style="text-align: justify;">Producers may also see increased cool cell pad life, as the system will operate less frequently allowing more time for the pad to dry between cycles.</p>urn:store:1:blog:post:136https://hogslat.com/new-product-introductions-at-ippe-2017New Product Introductions at IPPE 2017<p style="text-align: center;"><br /><img class="wp-image-2858 size-full" src="/images/uploaded/wp-content/uploads/2017/02/Show-Booth-e1486397238719.jpg" alt="Georgia Poultry booth at 2017 IPPE show " width="600" height="300" style="display: block; margin-left: auto; margin-right: auto;" /> <em>Georgia Poultry booth at 2017 IPPE show</em></p> <p style="text-align: justify;">Georgia Poultry highlighted two new products, scheduled for release later this spring, at this year's show in Atlanta.</p> <p style="text-align: center;"><img class="wp-image-2859 size-full" src="/images/uploaded/wp-content/uploads/2017/02/Light-Kit_1-e1486397258910.jpg" alt="" width="600" height="450" style="display: block; margin-left: auto; margin-right: auto;" /> <em>Classic Flood Light Kit illuminates control pan to encourage bird activity.</em></p> <p style="text-align: justify;">The Classic Flood Light Kit provides supplemental light to attract birds to the end control pan.

Rust causes steel to thin over time, reducing its strength&nbsp;and causing product failure.</p> <p style="text-align: center;"><img class="wp-image-2837" src="/images/uploaded/wp-content/uploads/2017/01/rust_surface770x400-e1485958424408.jpg" alt="Paint coating protect steel from elements until damaged." width="600" height="253" style="display: block; margin-left: auto; margin-right: auto;" /> <em>Paint coating protects steel from elements until damaged.</em></p> <p style="text-align: justify;">Any coating, which provides a barrier to moisture and oxygen, protects steel from corrosion. A painted surface provides an effective barrier until it is broken allowing moisture and oxygen to come in contact with the steel beneath. Rust develops at the breakage point and can even extend under the protective paint barrier.</p> <p style="text-align: center;"><img class="wp-image-2838" src="/images/uploaded/wp-content/uploads/2017/01/zinc-coating770x400-e1485958459893.jpg" alt="Galvanized coatings protect steel even when damaged." width="600" height="291" style="display: block; margin-left: auto; margin-right: auto;" /> <em>Galvanized coatings protect steel even when damaged.</em></p> <p style="text-align: justify;">Similar to paint, a galvanized coating forms a protective barrier to protect steel from moisture and oxygen. Galvanized coatings also provide a second method of protecting steel by electrochemically "sacrificing" the zinc in the present of corrosive elements.&nbsp;&nbsp; In other words, the zinc corrodes, until it is depleted, instead of the metal underneath. Because it is physically bonded to the metal, galvanized coating does not allow rust to extend beneath its surface.</p> <p style="text-align: center;"><img class="wp-image-2839" src="/images/uploaded/wp-content/uploads/2017/01/Galvanized-Layer770x400-e1485958497865.jpg" alt="Heavier G100 galvanized coatings offer 10% longer service life. " width="600" height="312" style="display: block; margin-left: auto; margin-right: auto;" /> <em>Heavier G100 galvanized coatings offer 10% longer service life.</em></p> <p style="text-align: justify;">Galvanized coatings are expressed in ounces per square ft with conventional coatings designated as G30, G40, G60, and G90. These refer to thickness of .30, .40, .60 and 90 oz./ft<sup>2</sup>, respectively. Corrosion resistance is directly proportionate to the amount of zinc coating on the steel. Therefore we would expect the service life of G90 steel to be roughly three times that of G30 in the same environment. Likewise, increasing the galvanized coating on a feed bin from G90 to G100 increases the bin's service life by 10%.</p> <p style="text-align: justify;">Galvanized steel is an excellent choice for use in feed bin fabrication, as it does not degrade when exposed to the sun's ultraviolet rays like painted coatings or poly bins.</p> <p style="text-align: justify;">In addition to heavier galvanized coatings, Hog Slat bins are manufactured from stronger Grade 55 steel, come with an improved ladder design and water deflecting Weather Edge&trade;. Every bin&nbsp;is backed by an&nbsp;extended 5-year warranty.

The owner was concerned because the static pressure in the new buildings was running between .10" and .14" while the static pressure in several older buildings of similar size was closer .20" - .22”. He suspected the fans in the newer buildings might not be operating correctly and not delivering their maximum ventilation rates. </p> <p style="text-align: center;"><img class="wp-image-2821 size-full" src="/images/uploaded/wp-content/uploads/2017/01/Iphone-wind-meter770x400-e1484057306532.jpg" alt="Inexpensive WeatherFlow wind meter for smartphones" width="770" height="440" style="display: block; margin-left: auto; margin-right: auto;" /> <em>Inexpensive<a href="/weatherflow-wind-meter"> WeatherFlow</a> wind meter for smartphones</em></p> <p style="text-align: justify;">We selected a spot 50' in front of first tunnel fan and recorded a reading of 715 fpm with a static pressure of .22" in the older facility. In the new building recordings from a similar location registered 805 fpm with a static pressure of only .14”. In other words, the new house was operating with a lower static pressure but still delivering almost 100 fpm higher wind speed.  </p> <p style="text-align: justify;">In fact, we were able to increase wind speed and reduce the static pressure in the older house by shutting off two fans. The static pressure went down to .12", and the wind speed accelerated to 770 fpm.</p> <p style="text-align: center;"><img class="wp-image-2822 size-full" src="/images/uploaded/wp-content/uploads/2017/01/Tunnel-Doors770x400jpg-e1484057331600.jpg" alt="Tego tunnel doors" width="770" height="440" style="display: block; margin-left: auto; margin-right: auto;" /> <em><a href="https://www.hogslat.com/tego-tunnel-door-cool-cell" target="_blank">Tego Tunnel Doors</a></em></p> <p style="text-align: justify;">Here's a simple test to perform in any house to find the balance point. Put the house in full tunnel mode and pick a spot 50’ in front of your fans to measure wind speed. Take a measurement with all fans running and then turn off a fan. Go back to the original measuring point and take another reading. If the wind speed went down then, the system is operating correctly. If it stayed the same or went up, then continue the process until you see a drop in airspeed. This exercise will tell you if you need to take action to correct the restrictions on the system. For example, cool cell pads may be clogged or not sized correctly, or the tunnel doors are restricting the airflow.</p>urn:store:1:blog:post:134https://hogslat.com/choose-the-right-heater-for-poultry-broodingChoose the Right Heater for Poultry Brooding<p style="text-align: justify;">By <strong>Paul Horne</strong><br />Gas-Fired Products Inc.</p> <p style="text-align: justify;"><img class="aligncenter wp-image-2828" src="/images/uploaded/wp-content/uploads/2017/01/Brooder-Feature-Image-e1484058925743-1024x532.jpg" alt="brooder-feature-image" width="600" height="312" style="display: block; margin-left: auto; margin-right: auto;" /></p> <p style="text-align: justify;">Radiant heat has gained wide acceptance across the industry for heating the brooder area of poultry houses.   Because radiant heat delivers heating energy directly to the birds and floor, radiant offers significant advantages compared to forced air heat including; 15-25% more efficiency, drier litter, and creating a heat-storing thermal reservoir for the birds at floor level.  </p> <p style="text-align: justify;">An additional benefit is the varying temperature gradients allowing the birds to seek their particular comfort zone. Temperature distribution graphs represent the heat profiles for each radiant heating product. Knowing the expected heating pattern for each style of radiant heater helps producers choose the best product for their particular application.</p> <p style="text-align: justify;">In the following diagrams, we show typical layouts for a 66' x 300' center brooder area for each type of radiant heaters. These are general layouts and not unique to a particular building design or geographical area. Each facility requires a heat loss calculation to determine the actual Btu/hr. needed.</p> <p style="text-align: center;"><img class="wp-image-2829" src="/images/uploaded/wp-content/uploads/2017/01/Brooder-e1484058947185.jpg" alt="Heating pattern for Gro40 brooder" width="600" height="312" style="display: block; margin-left: auto; margin-right: auto;" /> <em>Heating pattern for <a href="/hog-slat-gro40-brooder-heaters-lp-natural-gas">GRO40 brooder</a></em></p> <p style="text-align: justify;">40,000 BTU brooders with a round canopy project an even, circular heat pattern on the surface below. The emitter extending below the canopy reduces center hot spots and increases the overall diameter of the heat pattern.</p> <p style="text-align: justify;">Brooders normally have the lowest initial cost and offer a broad range of equipment options, including direct spark or pilot ignition systems which can be controlled individually or in zones. Installation is straightforward and flexible, allowing for multiple floor layouts. Brooders can be winched to different heights during the flock to change the heat pattern. Stainless brooders offer added corrosion protection for houses using litter treatments. It is important to thoroughly clean brooders after each flock to maintain optimal efficiency.</p> <p style="text-align: center;"><img class="wp-image-2830" src="/images/uploaded/wp-content/uploads/2017/01/Tube-e1484059020633.jpg" alt="Heating pattern for GROTube " width="600" height="312" style="display: block; margin-left: auto; margin-right: auto;" /> <em>Heating pattern for <a href="https://www.hogslat.com/radiant-tube-heaters" target="_blank">GROTube</a></em></p> <p style="text-align: justify;"><a href="/grotube"></a>Straight radiant tube brooding systems deliver a large pear-shaped heat profile with the highest floor temperatures located directly under the first tube and with lower temperatures at the far end. Typical tube lengths range between 30 ft.-60 ft. long with heating capacities ranging between 100,000 to 150,000 Btu/hr.</p> <p style="text-align: justify;">Straight tube heaters are mounted near the ceiling and are not raised and lowered like radiant brooders. Each model has a recommend mounting distance from the ceiling based on clearance to combustibles. Because straight tube heaters draw fresh air from outside the brood chamber, there is less maintenance than systems that bring their combustion air from inside the house.</p> <p style="text-align: justify;">Tube heaters have the advantage that they can be either a single stage or a two-stage unit, where the low fire will result in a different and smaller heat pattern.</p> <p style="text-align: center;"><img class="wp-image-2831" src="/images/uploaded/wp-content/uploads/2017/01/UTube-e1484059131118.jpg" alt="heating profile of Big Foot heaters" width="660" height="343" style="display: block; margin-left: auto; margin-right: auto;" /><em>Heating profile of <a href="https://www.hogslat.com/radiant-tube-heaters" target="_blank">Big Foot</a> heaters</em></p> <p style="text-align: justify;">Another radiant product type is the U-Tube heater, which offers an improved rectangular heat pattern when compared with the straight tube heaters. Because the heat inputs are lower, the hot spot under the burner is less intense than with the larger heat input straight tube heaters. Angling the reflectors towards the building sidewalls results in extended heating footprint. Sizes range from 12 ft. to 15 ft.long rated at 60,000 – 90,000 Btu/hr.</p> <p style="text-align: justify;">U-Tube heaters share the same advantages and disadvantages common to all tube heaters; higher installation costs along with the convenience of being mounted up out of the way and reduced maintenance.  </p> <p style="text-align: justify;">Their biggest advantage lies in the improved heat patterns. The heat patterns are larger with a more rectangular shape than brooders and more even temperature distribution than straight tube heaters. The rectangular heating profile of U-Tube heaters provides uniform heat distribution throughout the brood area. Chicks can easily move in and out of the temperature gradations seeking their individual comfort zones.    </p>urn:store:1:blog:post:132https://hogslat.com/the-field-guide-to-slat-repair-and-replacementThe Field Guide to Slat Repair and Replacement<p style="text-align: justify;"><a href="/images/products/manuals/hog-slat-field-guide-to-concrete-slat-repair-and-replacement.pdf"><img class="alignleft wp-image-2813" src="/images/uploaded/wp-content/uploads/2016/12/Screen-Shot-2016-12-20-at-12.14.31-PM-794x1024.jpg" alt="screen-shot-2016-12-20-at-12-14-31-pm" width="320" height="413" style="float: left;" /></a>Hog Slat Inc. teamed up with Vanberg Specialized Coatings and Altenburg Construction to produce a working guide for swine producers covering the repair and replacement of concrete slats.</p> <p style="text-align: justify;">Vanberg Specialized Coatings pioneered the use of cement and epoxy-based coatings specifically developed for use in animal confinement facilities. &nbsp; Working with producers from across the world, company founder Paul Vanberg formulated practical repair products for concrete surfaces and slats.</p> <p style="text-align: justify;">Altenburg Construction replaces over 20,000 slats in the upper Midwest region. &nbsp;Owner Andy Altenburg and Project Manager Tyler Sauck are experts in identifying potential problems with defective slats and beams.</p> <p style="text-align: justify;">Download your free copy of&nbsp;<a href="/images/products/manuals/hog-slat-field-guide-to-concrete-slat-repair-and-replacement.pdf"><em><strong> The Field Guide to Slat Repair and Replacement.</strong></em></a> &nbsp; &nbsp;</p>urn:store:1:blog:post:131https://hogslat.com/georgia-ffa-project-support-by-local-industryGeorgia FFA project support by local industry<p style="text-align: center;">When a local FFA chapter asked for industry support, Georgia Poultry's Heath Whiddon jumped at the chance.

"A deep pit has less moving parts than a scraper system and having 12 months of storage allows us to apply all the manure in the fall after the crops are out," explained Larry.</p> <p style="text-align: center;"><img class="wp-image-2760 size-large" src="/images/uploaded/wp-content/uploads/2016/11/Deep_1-e1478115883359-1024x682.jpg" alt="Access door to manure pit" width="690" height="460" style="display: block; margin-left: auto; margin-right: auto;" /> <em>Access door to manure pit</em></p> <p style="text-align: center;">&nbsp; The eight-foot-deep pit under the building consists of a steel reinforced concrete floor with eight-inch formed perimeter walls.

As the temperature increases, the sidewall curtains start to drop to allow natural airflow to cool the interior. At approximately 80 degrees the system switches to tunnel ventilation with the sidewall curtains closing and end tunnel curtains opening as the ten Windstorm 54" end wall fans stage on. &nbsp; Although deep pit structure may have a higher initial cost, there are several advantages for integrated farming operations. 12 months of storage allows fall application for maximum crop utilization. As Larry pointed out, a deep pit is virtually maintenance free with no moving parts compared to using a scraper or belt system to remove the manure from under the slatted area to a separate storage pit.</p>urn:store:1:blog:post:128https://hogslat.com/2nd-generation-stanchions2nd Generation Stanchions<p><img class="aligncenter wp-image-2770 size-large" src="/images/uploaded/wp-content/uploads/2016/11/Stachions_1-e1478116542140-1024x477.jpg" alt="stachions_1" width="690" height="321" style="display: block; margin-left: auto; margin-right: auto;" /></p> <p>The pen gestation continues to evolve as producers gain "real world" experience managing production systems.  </p> <p>In 2012 Prestage Farms remodeled an existing finishing complex into breeding and farrowing units and installed stanchions in the pen gestation. You can read more about the remodel project <a href="http://www.hogslat.com/prestage-selects-stanchions-for-remodel-project">here.</a>   Production Manager, Russ Goss, explained some of the changes made in new sow units built this year,   "In the new facilities, we increased the square footage from 19.5 to 23 per sow, and the stanchion width changed from 19" to 24" on center. In addition, the rodded stanchion dividers were increased from 18” to 48”.</p> <p>"Extending the dividers changed the behavior of the dominant sows in a pen. Shorter dividers enabled the boss sow to disturb the other animals, and you would see some of them repositioning during the feeding period. The 48" divider prevents the aggressive animals from reaching the shoulders of their pen mates. Instead of going down the line and disrupting other animals, they quickly figure out they can't move anybody and just return to their spot."</p> <p>"The other thing we see is at any one time 50% of the animals in a pen will be lying in the stanchions.   They never laid in the shorter stanchions, but would always be lying around the "donut" in the middle with their backs against the pen perimeter gating.   A sow always wants to lay with her back against something. She feels secure in the longer stanchions and she appears comfortable staying there, but is also free to leave and move around the pen." <span style="text-decoration: line-through;"> </span> Russ continued, “We have noticed that after the initial fighting to establish the pecking order in the pen, the sows are noticeably calmer and quieter compared to our stall barns.”</p> <p>"Using pen gestation with stanchions fits our system and personnel. The ESF systems are really an intriguing concept... being able to feed and track sows individually in loose housing. Maybe it's our genetics, but I don't think it's that important for us to feed a sow individually all the way through gestation. From our experience, we can effectively condition the sow the first 6 weeks in gestation. However, if we do not have all sows in the ideal condition, we will group them together and set all feeders in the pen accordingly.</p>urn:store:1:blog:post:129https://hogslat.com/sowmax-key-to-increasing-feed-consumptionSowMAX Key to Increasing Feed Consumption<p><img class="aligncenter size-large wp-image-2774" src="/images/uploaded/wp-content/uploads/2016/11/Sow-Feeders_1-1024x667.jpg" alt="sow-feeders_1" width="690" height="449" style="display: block; margin-left: auto; margin-right: auto;" /></p> <p>A move to 21-day weaning along with an increasing born live, sent Great Lake Pork, headquartered in Allendale, Michigan in search of the best method for ad-lib feeding in farrowing.&nbsp;</p> <p>"Improved sow genetics resulted in more pigs farrowed plus we wanted to boost pig weights by weaning later. We needed to push more feed to the sows and increase consumption," commented Great Lakes Pork, partner Joel Phelps. &nbsp;</p> <p>After trialing several different feeder and water combinations, Great Lake Pork settled on a Hog Slat's SowMAX with a floor mounted cup waterer. &nbsp; "We feel the stainless steel SowMAX dispensers are more durable and easier to install on the different feed bowls in our system. The sow activated trigger mechanism is more reliable than models incorporating plastic balls or electronic timers, " said Joel. &nbsp;</p> <p>"We have barns where the ad-lib hoppers are hand-filled and those with automated delivery systems; the results are the same, one just requires a little more labor. We fill the feeder starting on day one and let the sow have all the feed she wants.&nbsp;&nbsp; That's the beauty of ad-lib, there's no guessing like with hand-feeding, sows eat as individuals when they are ready." &nbsp;</p> <p>"Although we don't weigh individual litters, we know the sows are milking well, and they are doing it without losing body weight. They are coming out of the farrowing houses in very good condition which helps in the breeding barn." &nbsp;</p> <p>Joel finished by saying; &ldquo; As soon as we finished the trial and decided on the equipment we made the switch across the entire system, 18 sow farms in all. That was over three years ago and we&rsquo;ve never regretted it.

In the outside lots, the hens have access to portable shades along with supplemental feed and water.</p> <p style="text-align: center;"><img class="wp-image-2783 size-large" src="/images/uploaded/wp-content/uploads/2016/11/Egg-packer_1400px-e1478177683710-1024x341.jpg" alt="Manual egg packer and automatic version shown" width="690" height="230" style="display: block; margin-left: auto; margin-right: auto;" /> <em>Manual egg packer and automatic version</em></p> <p>A second egg collection occurs mid-afternoon. Smaller facilities hand pack the eggs from the center collection belt while larger operations utilize an automated packing machine. Walk-in egg coolers capable of maintaining 45-degree temperatures hold the eggs until the farm&rsquo;s weekly pickup. The building&rsquo;s side doors remain open until after dark with the interior lights left on to draw the hens in before closing up for the night. Approximately &frac12; hour before shutting down the building lights, the nest floors lift up gently pushing the hens out of the colony nest and blocking access until the next morning.</p>urn:store:1:blog:post:125https://hogslat.com/avoid-slat-disasters-with-a-simple-visual-examAvoid Slat Disasters with a Simple Visual Exam<p><img src="/images/uploaded/wp-content/uploads/2016/10/Image-1-e1477689006909-1024x657.jpg" alt="image-1" width="690" height="443" style="display: block; margin-left: auto; margin-right: auto;" /></p> <p>&nbsp;</p> <p>Andy Altenburg is an expert when it comes to bad slats. &nbsp;Sitting at a massive, 1200-pound conference table made with a full-size concrete slat, the owner of Altenburg Construction in Lewisville, MN explained how he got started in the business.</p> <p>&nbsp;</p> <div id="attachment_2729" class="wp-caption aligncenter"><img src="/images/uploaded/wp-content/uploads/2016/10/Image-2-e1477689043919-1024x682.jpg" alt="Altenbury Construction Conference Table" width="690" height="460" style="display: block; margin-left: auto; margin-right: auto;" /> <p class="wp-caption-text" style="text-align: center;"><em>Altenburg Construction Conference Table</em></p> </div> <p>&nbsp;</p> <p>&ldquo;I was working for a local producer at a nursery site. We were building new buildings like crazy during that time and got behind grouting slats. Grandpa had an old portable mixer out back, and I figured I could mix cement and sand together, and I needed the money. Later I started repairing slats, and when some of the slats were too bad to fix I figured out a way get the old ones out and new ones in.&rdquo;</p> <p>&ldquo;Our goal from the very beginning was to develop tools to make slat replacement faster with less labor. We developed and manufactured the machines we needed learning as we went. Our volume continues to grow each year because we are getting more efficient. We are on track to replace 20,000 slats by the end of 2016.&rdquo;</p> <p>Project Manager, Tyler Sauck explained some guidelines to use when examining the condition of slats in a facility.</p> <div id="attachment_2731" class="wp-caption aligncenter"><img src="/images/uploaded/wp-content/uploads/2016/10/Image-3-e1477689088768-1024x682.jpg" alt="Look for damage on the side when crack are viewed on top" width="690" height="460" style="display: block; margin-left: auto; margin-right: auto;" /> <p class="wp-caption-text" style="text-align: center;"><em>Look for damage on the side when cracks are visible on top</em></p> <p class="wp-caption-text" style="text-align: center;"><em><br /></em></p> </div> <p>&ldquo;The first thing to judge when you see a crack in slat is how deep it is.

Used in buildings that can be both dusty and humid, with fluctuations in voltage and varying workloads we subject our motors to a very hostile work environment.</p> <p>When selecting replacement motors, it is important to select motors that are both efficient and designed with a “safety factor” that will allow them to last under harsh conditions.</p> <p>While you may be familiar with the term Service Factor or S.F., there are a couple of important designations found on a motor nameplate that may need more clarification.</p> <p>Service Factor is defined as a motor’s ability to operate under a short-term load.   The higher a motor’s S.F. rating, the more durable the motor.  Motors with high S.F. are expected to last longer. To illustrate, a 1-1/2 Hp motor with a 1.5 S.F. can provide 2.25 Hp for short-term use.   However, it is not a good practice to continuously operate a motor above the rated workload. In other words, the same 1-1/2 Hp motor with  1.5 SF would not be selected to power a 60″ fan originally shipped with a 2 Hp motor.</p> <p>Full Load Amps or F.L.A. represents the amount of current the motor is designed to draw at the rated horsepower. In the example nameplate, this means that when the motor is running under a full load at 230 volts, we can expect it to draw 5.4 amps. Motors with a lower F.L.A. for the amount of horsepower are considered more efficient to operate.</p> <p>Service Factor Amps or S.F.A. represents the amount of current the motor will draw when running at the full Service Factor. In the example nameplate, the S.F.A. is eight amps at 230 volts.</p> <p>Continually exceeding the S.F.A. shown on the nameplate can shorten motor life. Motors with a higher S.F.for the same horsepower have an increased “safety factor” and are expected to last longer under harsh conditions.</p> <p>The most efficient, rugged motors are designed with a higher S.F., lower F.L.A., and higher S.F.A ratings. By comparing the information on a motor nameplate, we can select the best replacement motors for feeding and ventilation equipment.</p> <p>Hog Slat designed the GrowerSELECT line of motors to help simplify a producer’s decision on selecting replacement motors. GrowerSELECT motors feature a high Service Factor (as high as 1.5) and higher  S.F.A. rating to increase motor life.  Each model number is a direct cross to the most popular brands of feed systems and fans used on producers’ farms. No matter what your existing brand of equipment we have a GrowerSELECT motor designed to replace it and save money while doing so. <a href="http://www.hogslat.com/grower-select-electric-feedline-auger-and-fan-motos">Shop GrowerSELECT motors.</a></p>urn:store:1:blog:post:119https://hogslat.com/2nd-gen-sensor-featured-in-growerselect-feed-line-control2nd Gen Sensor featured in GrowerSELECT Feed Line Control<div id="attachment_2593" class="wp-caption aligncenter"><img class="wp-image-2593 size-full" src="/images/uploaded/wp-content/uploads/2016/06/HS752_2-web-e1466086712407.jpg" alt="GrowerSELECT Proxy Control at the 2016 World Pork Expo" width="600" height="585" /> <p class="wp-caption-text">GrowerSELECT Proxy Control on display &nbsp;at the 2016 World Pork Expo</p> </div> <p>One of the products Hog Slat introduced at the 2016 World Pork Expo is designed to give pork producers an improved method for controlling feed line motors.</p> <p>The&nbsp;<strong><a href="http://www.hogslat.com/grower-select-proximity-drop-tube-control-hs752">GrowerSELECT Proximity Drop Tube Control</a></strong>&nbsp;features a flat proxy sensor that can detect feed levels through the plastic housing.

As the industry moves from gestation stalls to group housing designs, slat quality becomes an important factor. Rather than being confined to a small slatted area, sow movement over an entire slatted pen subjects them potential injury from defective flooring design.</p> <p>Good concrete slat design, construction, and maintenance can minimize foot and leg problems associated with swine production.</p> <p>The most critical feature in slat design is producing slats with a flat top surface. &nbsp;Slats with uneven and inconsistent surface place additional stress on pig&rsquo;s feet and joints.</p> <div id="attachment_2226" class="wp-caption aligncenter"><img class="size-large wp-image-2226" src="/images/uploaded/wp-content/uploads/2016/01/hand-cast-vs-machined-slats_edit_web-1024x300.jpg" alt="Level top provides surface that is easier on pig's feet and joints." width="690" height="202" /> <p class="wp-caption-text">Level top provides a surface that is easier on pig&rsquo;s feet and joints.</p> </div> <p>Many methods used for producing concrete slats consist of placing wet cast concrete into multiple steel forms and hand troweling to finish. &nbsp;It is harder to build slats with a consistently flat surface by&nbsp;hand finishing methods.</p> <p>&nbsp;</p> <div id="attachment_2162" class="wp-caption aligncenter"><img class="size-large wp-image-2162" src="/images/uploaded/wp-content/uploads/2016/01/rotoscreed_web-1024x683.jpg" alt="Rotoscreen &quot;striking off&quot; dry cast concrete on mold to apply flat surface on slats.

Slats built using concrete with a low water-to-cement ratio are longer lasting and more resistant to wear.</p> <p>The water-cement ratio refers to the ratio of the water weight&nbsp;to the cement weight&nbsp;used in a concrete mix. A lower ratio leads to higher strength and durability but makes the mix difficult to work with and form. For this reason, most slats are produced with wet cast concrete using&nbsp;a water-cement&nbsp;ratio of 0.5. Machined slats are manufactured from dry cast concrete with a water-cement ratio of less than .39.</p> <p><img class="aligncenter size-large wp-image-2228" src="/images/uploaded/wp-content/uploads/2016/02/Cement-Water-Ratio_web-1024x523.jpg" alt="Cement-Water-Ratio_web" width="690" height="352" /></p> <p>A cubic yard of wet cast concrete formulated with 500 pounds&nbsp;of cement contains 250 pounds of water, while a dry cast mix only contains 195 pounds. As the excess water leaves during the curing process, it creates microscopic pores that reduce the final strength of a slat. Compromised slat strength can lead to many problems down the road, including expensive repairs, equipment damage and injury to pigs and farm personnel.</p> <dl id="attachment_2143" class="wp-caption aligncenter"><dt class="wp-caption-dt"><img class="wp-image-2143 size-large" src="/images/uploaded/wp-content/uploads/2016/01/Concrete-slat-repair-1024x318.jpg" alt="Wet cast slats by feeder showing exposed aggregate damage." width="690" height="214" /></dt><dd class="wp-caption-dd">Wet cast slats by feeder showing exposed aggregate damage and repaired surface with Vanberg Specialized Coatings.&nbsp;</dd></dl> <p>Maintaining surfaces and edges of slats, as they wear over time, is essential in providing pigs with a comfortable flooring surface. Areas around waterers and feeders are the first to show significant damage. When the need arises&nbsp;for concrete slat repair, choose a repair mortar designed for slat repair versus generic concrete repair products. Mortars designed for slat repairs feature cement and epoxy formulations with higher cure strengths and faster cure times. The amount of damage will determine the type of repair product needed. For simple repairs, less than 1/4&Prime; in depth, a cost effective cement mortar can be used. More severe corrosion requires the use of epoxy mortars to hold the repair patch in place.

Most companies have identified the most efficient methods to build an anchor bearing, motor, feeder, nipple waterers, etc.</p> <p>&nbsp;</p> <p>The real cost difference comes from the delivery of those products to the end user. The standard model of distribution, in our industry, involves a manufacturer producing a product line, warehousing it, and employing a sales force to establish a dealer network.</p> <p>&nbsp;</p> <p>The dealer network stocks the equipment, maintains a storefront, hires salespeople, installs, and services the production systems in a local area for the brand of equipment they represent.</p> <p>This particular type of distribution model has changed very little over the history of the livestock and poultry production industries. Each member of this distribution model is an independent business entity and is free to add whatever margins they deem necessary (or possible) to the final cost a producer pays.</p> <div id="attachment_2179" class="wp-caption alignleft"><img class="wp-image-2179 size-medium" src="/images/uploaded/wp-content/uploads/2016/01/SupplyChain_web-300x300.jpg" alt="GrowerSELECT supply chain removes extra dealer margins to producer." width="300" height="300" /> <p class="wp-caption-text">GrowerSELECT supply chain removes extra margins to reduce the final cost to end users.</p> </div> <p>&nbsp;</p> <p>&nbsp;</p> <p>Sold through a different type of distribution model, GrowerSELECT goes directly to livestock and poultry growers through our network of regional local stores.

Wait a minute; the first paragraph said the cost of manufacturing was the same for everyone.</p> <p>&nbsp;</p> <p>True. But if a brand has a loyal dealer network, the pricing to the dealer network will not be challenged.

An auger or fan company buys a motor from a motor manufacturer, puts their logo on it and sells it to a local supplier. The local supplier sells the motor to the end user adding little value to the final price. A local supplier has few other options. Their volume of a particular motor isn&rsquo;t high enough to go directly to a motor manufacturer, and they have little negotiating power with their chosen brand vendor. The brand company has little incentive to lower the cost to a loyal dealer network. In fact, a brand company can charge different prices in different geographical locations depending on market pressure.</p> <p>&nbsp;</p> <p>&nbsp;</p> <p>Compare this with&nbsp;<a href="http://www.hogslat.com/grower-select-electric-feedline-auger-and-fan-motos" target="_blank">GrowerSELECT motors</a>. Our network of&nbsp;<a href="http://www.hogslat.com/t/SalesAndStoreLocator" target="_blank">over 70 store locations</a>&nbsp;and turnkey construction business allows for large purchases of motors direct from a manufacturer. We forecast purchase amounts for each store location and ship directly with minimal warehousing cost. Local retail pricing continually drives us to buy at a more competitive price.</p> <p>&nbsp;</p> <p>The conventional distribution chain is directed from the TOP DOWN versus&nbsp;the GrowerSELECT model which is driven from the BOTTOM UP. Lower pricing for comparable products is the result.</p> <p>&nbsp;</p> <p>The GrowerSELECT distribution model also affects product responsibility. Because we interact directly with the end users, we deal directly with any problems arising with the installed products. We sell it; we service it, and the end user works with one company.</p> <p>&nbsp;</p> <p>The traditional marketing chain allows room for some question regarding&nbsp;who&nbsp;is&nbsp;responsible for dealing with equipment failures when those problems arise. The manufacturer can blame poor installation, dealer system design, or a number of other reasons (excuses) for a product&rsquo;s failure. A local supplier can blame the brand company for poor design or manufacturing flaws. The GrowerSELECT distribution system eliminates &ldquo;finger pointing&rdquo; and focuses on providing accountability to each and every customer.</p> <p><img class="alignleft wp-image-2183 size-full" src="/images/uploaded/wp-content/uploads/2016/01/gold-coins-on-calculator-with-GS-logo1-e1452883851672.jpg" alt="gold-coins-on-calculator-with-GS-logo" width="450" height="300" />Our customers produce commodities.

Every manufacturer, distributor, and dealer adds their own margin and the final cost includes these &ldquo;stacked margins.&rdquo;</p> <p>&nbsp;</p> <p>This type of distribution system has evolved over time and in many cases is the best method to deliver products efficiently to consumers. &nbsp;The margins charged by these &ldquo;middle men&rdquo; aren&rsquo;t evil or bad as long as they add value to a product through manufacturing, warehousing, installation or technical support.</p> <p>&nbsp;</p> <p>We would all agree that the structure of the poultry and hog industries has changed a great deal in the last 20 years, and some parts of the supply chain have changed along with it. &nbsp;At one time, local dealers sold, mixed and delivered complete feed to production sites. &nbsp;As producers became larger, they quickly moved to reduce the number of people involved in formulating and manufacturing feedstuffs and realized substantial cost savings.</p> <p>&nbsp;</p> <p>The supply chain to deliver feed systems and ventilation systems has not changed for decades. &nbsp;Companies design and manufacture products, warehouse, finished goods and hire representatives to &ldquo;set up&rdquo; local dealer networks. The dealers provide a storefront, promote the brand locally, order and stock parts, hire salespeople and installation crews. &nbsp;The industry is still delivering production equipment to the end user the same way it did when the number of producers was much larger.</p> <p>&nbsp;</p> <p>&nbsp;</p> <p><img class="alignleft size-medium wp-image-865" src="/images/uploaded/wp-content/uploads/2014/07/Grower-Select-2x6-R-small-300x88.jpg" alt="Grower Select 2x6 &reg;" width="300" height="88" style="float: left;" />Hog Slat developed the GrowerSELECT&reg; line to collapse the supply chain, reduce margins and lower the final cost.&nbsp; How?</p> <p>&nbsp;</p> <p>Hog Slat established a network of company stores in the major livestock and poultry production areas of the U.S. &nbsp; This system was backed up with distribution centers totaling over 600,000 square feet. We control distribution costs and the margins charged against the final purchase price.</p> <p>&nbsp;</p> <p>The resulting volume of goods sold through our store system and large turnkey construction business enabled Hog Slat to justify the investment needed to manufacture feed and ventilation systems for our customers. We design and control the manufacturing process and the costs involved.</p> <p>&nbsp;</p> <p>Typically, manufacturing companies do not have retail systems in place to deliver, install and service systems on a local level. Local dealers do not have volumes large enough to hire engineers to design and manufacture products for their local markets. &nbsp;Hog Slat is the only equipment supplier in the poultry and swine industries to integrate the supply chain vertically.</p> <p>&nbsp;</p> <p>If you have priced any GrowerSELECT equipment, you have probably been pleasantly surprised at the cost savings. You may have even hesitated to buy it because of the low price. &nbsp; After all, &ldquo;you only get what you pay for&rdquo; is true. Buying products through the traditional distribution means you are paying the built in margin stack. &nbsp;If you are ready to stop paying &ldquo;margin stack&rdquo; on feed and ventilation systems contact one of our local stores about GrowerSELECT, go online to www.hogslat.com &nbsp;or call 800-949-4647.</p>urn:store:1:blog:post:102https://hogslat.com/hog-slat-romania-receives-iso-9001-certificationHog Slat Romania Receives ISO 9001 Certification<p class="p1"><span class="s1"><img class="alignleft wp-image-2031 size-full" src="/images/uploaded/wp-content/uploads/2015/10/romania.jpg" alt="" width="427" height="580" style="float: left;" /></span></p> <p class="p1"><span class="s1">Hog Slat&rsquo;s Romanian manufacturing operation, located in Arad, received &nbsp;ISO 9001, ISO 14001 and OHSAS 18001 certifications earlier this year.

Feed is always available for them, but when they are really hungry they all want to be at the feeder together. The&nbsp;<a href="http://www.hogslat.com/hanging-chicken-feeders" target="_blank">30 pound hanging poultry feeder</a>&nbsp;provides plenty of space and the needed capacity to keep multiple days worth of feed available to a smaller flock or meet the feeding needs of a larger flock without having to refill as often. The design of the hanging feeder allows 3 different adjustments to control the amount of feed that flows into the pan which helps reduce wasted feed that might be pushed out of the pan if the level was too high.&nbsp;We started the birds as chicks using the&nbsp;<a href="http://www.hogslat.com/hanging-chicken-feeders" target="_blank">15 pound hanging poultry feeder</a>, which is the same design but does not feature an adjustable feed flow rate.</p> <p style="text-align: justify;"><img class="aligncenter wp-image-2003" src="/images/uploaded/wp-content/uploads/2015/06/30-pound-hanging-feeder-pan-300x200.jpg" alt="30 pound hanging feeder pan" style="display: block; margin-left: auto; margin-right: auto;" /></p> <p style="text-align: justify;">As you can see in the video above, the feeder is hanging from the chicken tractor&rsquo;s roof frame which serves multiple beneficial purposes. First, when the feeder is hanging as opposed to sitting on the ground, it discourages the birds from trying to scratch the feed and also makes the red edge of the feed pan an unstable platform which discourages the birds from trying to perch or roost on the feeder. Next, when the feeder is hanging you can move the coop without having to pull the feeder out first. Lastly, when the feeder is off the ground it makes it more difficult for ants or other bugs to get into the feed.</p> <p style="text-align: justify;">Both models of the plastic hanging feeder are easy to clean when they become dirty or after you&rsquo;ve finished raising your flock. Simply brush loose any solid debris from the feeder, soak in a tub of water and cleaning solution for 10 minutes, wipe down the interior and exterior of the feeder and then rinse clean. Hang the feeder out to dry or wipe down with paper towels and you&rsquo;ll be ready to refill with feed or store until you need to feed your next flock.</p> <p style="text-align: justify;">&nbsp;</p> <p style="text-align: justify;">Browse our full selection of FARMSTEAD Equipment to help you raise your poultry at&nbsp;<a href="http://www.hogslat.com/farmstead-equipment" target="_blank">www.hogslat.com/farmstead-equipment</a>.</p>urn:store:1:blog:post:81https://hogslat.com/feed-chain-torture-chamberFeed Chain Torture Chamber<p style="text-align: justify;">One of the benefits we list for the Grow-Disk system is a “superior chain.”  The feed chain with molded plastic disks is the main component of the system, physically moving feed to a feeder or sow drop.</p> <p style="text-align: justify;">I dropped in on Hog Slat’s engineering group to see what I could find out.  I found Tim Hawkins, the project engineer for the Grow-Disk product line. Tim led me to a complicated looking run of 12 corners occurring in less than eight feet with intersecting vertical and horizontal corners.</p> <p><img class="aligncenter wp-image-1499 size-full" src="/images/uploaded/wp-content/uploads/2015/01/Chain-Disk-torture-_blur.web_-e1445958500270.jpg" alt="Chain-Disk-torture-_blur.web" width="800" height="533" style="display: block; margin-left: auto; margin-right: auto;" /></p> <p style="text-align: justify;">“The drive unit is off of it now,” Tim explained,  “but we ran different brands of chain through this setup to show accelerated wear. Look at this…..see the metal filings in the bottom of the corner? Those showed up when we ran the last batch of electroplated chain through the unit.  The process of electroplating weakens steel causing it to wear faster.”</p> <p><img class="aligncenter wp-image-1500 size-full" src="/images/uploaded/wp-content/uploads/2015/01/Chain-Corner-w_-Filings_web-e1445961447581.jpg" alt="Chain-Corner-w_-Filings_web" width="800" height="533" style="display: block; margin-left: auto; margin-right: auto;" /></p> <p style="text-align: justify;"> </p> <p style="text-align: justify;">“This confirmed the difference between using hardened steel compared to galvanized or electroplated chain.  Hardened steel is high carbon steel given heat treatments of quenching followed by tempering.  The result is tough steel chain that resists wear without being brittle. We can run a hardened chain for days and never see filings like that.”</p> <p style="text-align: justify;">“With most chain feeding systems you have to adjust for “chain stretch” after the systems have operated for awhile.  We don’t think the individual chain links stretch but as they go around corners constantly rubbing together they elongate because of wear.”</p> <p style="text-align: center;"><img class="aligncenter wp-image-1501 size-full" src="/images/uploaded/wp-content/uploads/2015/01/Compare-three-chains_web-e1445961489660.jpg" alt="Compare-three-chains_web" width="800" height="533" /></p> <p style="text-align: center;"> </p> <p style="text-align: justify;">“The only reason, to galvanize steel, is to prevent rust.  With the fat and oils in the feed, the chain doesn’t rust in the tube.  Most brands of feeding chain is galvanized for it’s appearance before installation.  A new bag of Grow-Disk may have some surface rust on it, not a big deal.”</p> <p style="text-align: justify;"> </p> <p style="text-align: justify;">We next looked at how well the plastic disks are fastened to the chain.</p> <p style="text-align: justify;">“We placed each brand of chain link in a load cell and attached it to a winch, measuring the force needed to pull the disks off the link.”</p> <p><img class="aligncenter size-medium wp-image-1505" src="/images/uploaded/wp-content/uploads/2015/01/Chain-Disk-link_web-291x300.jpg" alt="Chain-Disk-link_web" width="291" height="300" style="display: block; margin-left: auto; margin-right: auto;" /></p> <p style="text-align: justify;"> </p> <p style="text-align: justify;">“Most of the disks pulled off at 300 lbs., although one slipped at only 160 pounds!  We applied over 600 lbs. of force to the Grow-Disk disk before it slipped.”</p> <p style="text-align: justify;">“First of all, the disks are manufactured from nylon, a stronger, denser plastic instead of polypropylene.<br />Second, if you look closely at all the chains the connector welds are smooth, except on the Grow-Disk chain….see the little knob?  That knob prevents the nylon disk from slipping…the nylon has to break instead of just slipping.”</p> <p><img class="aligncenter wp-image-1503 size-medium" src="/images/uploaded/wp-content/uploads/2015/01/Chain-Link-closeup_web-300x281.jpg" alt="Chain-Link-closeup_web" width="300" height="281" style="display: block; margin-left: auto; margin-right: auto;" /></p> <p style="text-align: justify;"> </p> <p style="text-align: justify;">“Most feeding chain suppliers buy general purpose chain with the knob removed. By using a chain fabricated “in-house” and designed specifically for feed systems, we can produce a superior product.”</p> <p style="text-align: justify;">“A strong plastic disk is important because the drive sprocket powering the entire system makes contact with each, single disk for a brief moment.  If an individual disk slips this causes the chain to be slightly out of alignment causing possible jams.”</p> <p style="text-align: justify;">You can be confident using Grow-Disk chain knowing you are buying the very best even though the cost is usually less.</p> <p style="text-align: justify;">Hog Slat streamlined distribution system reduces margin stacking.  We manufacture and source products direct to you….eliminating extra dealer margins.</p> <p><img class="aligncenter size-medium wp-image-892" src="/images/uploaded/wp-content/uploads/2014/08/SupplyChain-300x300.jpg" alt="Hog Slat Supply Chain" width="300" height="300" style="display: block; margin-left: auto; margin-right: auto;" /></p> <p style="text-align: justify;">Good product engineering does not add cost to a product but instead takes manufacturing processes into account to reduce costs. It costs no more to spec a hardened chain with knobs intact to provide a better contact for injecting the nylon disk.  The result is a superior product that lasts longer on your farm.</p> <p style="text-align: justify;">Grow-Disk systems, <a href="http://hogslat.com/grower-select-grow-disk-feed-system">read more…</a></p>urn:store:1:blog:post:97https://hogslat.com/farmstead-chickens-move-outdoorsFARMSTEAD Chickens Move Outdoors<p style="text-align: justify;">The FARMSTEAD broiler flock has moved outdoors!

The secondary objective was to measure the amount of labor required to manage the sows using each type of feeding system, specifically during lactation. Two farrowing rooms were observed in this study. One-half of the farrowing crates in each room were retrofitted with SowMAX feeders. Farrowing occurs every other week at the Swine Educational Unit (n=24 sows per group). At the present time, data has been collected from 36 sows utilizing SowMAX feeders and34 sows that were hand fed.There were significant interactions between season (winter versus summer) and feeding strategy (SowMAX versus hand feeding) for both sow and piglet performance and sows’ daily feed intake patterns. Consequently, the data is presented seasonally. Sow and piglet performance during lactation is shown in Tables 1 and 2, while sow daily feed intake patterns are shown in Figure 1 and 2. Tables 3 and 4  contain sow rebreeding performance and baby piglet death losses, respectively. (see complete article online including tables) There were no significant interactions between seasons and feeding strategy for this data, therefore the means in these tables were averaged across seasons. </span></p> <hr /> <h3 class="p1" style="text-align: justify;">Total feed intake and daily feed intake appear to be superior for sows being fed with the SowMAX feeders. This was particularly true during the summer months.</h3> <hr /> <p style="text-align: justify;"> </p> <p class="p1" style="text-align: justify;">The data in all the Tables are the mean values and the standard errors. The last column in each table is the p value, which is a measure of how different the means is statistically. In a general sense, the p value can be thought of in the following manner. If the experiment was repeated 1000 times, then one would expect the same result as indicated by the p value due to chance. For example, in Table 1 the p-value for total feed intake is 0.043. Sows fed with the SowMAX feeders consumed 17.2 lbs. more feed during lactation compared with those fed by hand. What this means is that there is less than 5% chance that this difference is simply due to chance and random events and a 95% chance that it is due to the SowMAX feeder. Conversely, the body weight of sows after farrowing has a p value of 0.671. What this means is that there is more than 50% chance that the differences observed are, in fact, due to chance or random events and not related to the way they were fed (SowMAX versus Hand Feeding). The p values in bold are those that are less than 0.05 that is considered to be highly significant in the scientific literature. In other words, there is a 95% probability that the current difference is due to the feeding system. The p values in bold italics are ones with p values between 0.05 and 0.20. These are considered important trends in scientific literature. Usually what happens with trends is that as more data is collected (more observations) then their p values move closer to 0.05.</p> <p class="p1"><img class="aligncenter wp-image-1914 size-large" src="/images/uploaded/wp-content/uploads/2015/05/SowMax-Feed-Intake-patterns-627x1024.jpg" alt="SowMax Feed Intake patterns" width="627" height="1024" style="display: block; margin-left: auto; margin-right: auto;" /></p> <p class="p1" style="text-align: justify;">In general, both total feed intake and daily feed intake appear to be superior for sows being fed with the SowMAX feeders. This was predominantly true during the summer months. Daily sow feed intake was consistently greater during the summer with the SowMAX feeders after the first week of lactation compared to hand feeding. This was also true during the winter months due to a more consistent feed intake pattern over the entire lactation period, with less variation from day to day. During the summer, sows had a similar pattern of daily feed intake with both feeding systems. However, sows in farrowing crates with a SowMAX feeder simply ate more. In contrast, during the winter the increase in feed intake for sows with the SowMAX feeder was due mainly to the lack of several transient periods of decreased feed intake which were prevalent when sows were fed. In this study, there was less feed wastage on a dry matter basis with the SowMAX feeders. Additionally, SowMAX feeders required less labor and maintenance (cleaning) by employees that fed the sows, especially during the summer months when sow water consumption is high.</p> <p class="p1" style="text-align: justify;">The increased feed intake during lactation resulted in better pre-weaning weight gain by the piglets. There were no differences in piglet mortality or rebreeding performance between treatments. A rather interesting observation was the lower body temperature during the last week in lactation of the sows utilizing the SowMAX feeders. This was even more prominent during the summer months and most likely is the factor responsible for the increased daily feed intake in these sows. This is most likely due to them being able to regulate their feed intake during the day. It has been shown that after consumption of a single large mealthe core body temperature increases, compared to intake of the same amount that is distributed evenly over a longer period of time. It appears the sows actually do regulate their feed intake, at least in part, based on the temperature of the ambient environment.</p> <p class="p1" style="text-align: justify;">To obtain a copy of the full report contact us at: <a href="http://webinfo.us@hogslat.com/">webinfo.us@hogslat.com</a></p>urn:store:1:blog:post:96https://hogslat.com/cut-weld-panels-for-diy-hog-gatingCut & Weld Panels for DIY Hog Gating<p style="text-align: justify;">Hog Slat's Cut &amp; Weld panels enable you to build DIY steel gates for&nbsp;your hog farm.

As your chicks become tall enough to see the top of the plate they cannot help but want to get up there. The slanted design of the heating plate cover prevents birds from perching on the plate and piling it with droppings. The small &ldquo;streaks&rdquo; from their tail ends sliding down the cover will be much easier to clean after the brooding process than an entire plate covered in poop!</p> <p style="text-align: justify;">&nbsp;</p> <p><img class="aligncenter size-full wp-image-1936" src="/images/uploaded/wp-content/uploads/2015/05/Comfort-Heating-Plate-for-Chicks-Cover_Cropped-Resized.jpg" alt="Comfort Heating Plate for Chicks Cover" width="670" height="670" style="display: block; margin-left: auto; margin-right: auto;" /><br />Our&nbsp;<a href="http://www.hogslat.com/adjustable-chicken-drinking-bucket-with-3-nipples" target="_blank">chicken drinking bucket with 3 nipples</a>&nbsp;has been a huge hit and we know exactly why! When you compare the features and functions of our bucket to most other poultry drinking systems, you will quickly find that the drinking bucket keeps fresh, clean water available for&nbsp;your birds without requiring much work at all from you. In addition, when kept at the proper height for your birds, very little, if any, water makes it to the floor of your coop or brooder.</p> <p style="text-align: justify;">&nbsp;</p> <p><img class="aligncenter size-full wp-image-1930" src="/images/uploaded/wp-content/uploads/2015/05/3-Nipple-Bucket-and-Dry-Litter_Cropped-Resized.jpg" alt="3 Nipple Bucket and Dry Litter" width="670" height="800" style="display: block; margin-left: auto; margin-right: auto;" /></p> <p style="text-align: justify;">&nbsp;</p> <p style="text-align: justify;">Other poultry watering systems can leak, get filthy or be knocked over very easily by your chickens or other poultry. The drinking bucket hangs out of the way and uses commercial grade poultry nipples to provide a consistent flow of water to your birds when they want it.&nbsp;This keeps your litter or shavings dry and helps your birds stay cleaner and healthier. As you can see in this photo, dry litter absorbs moisture and odors from the chicken droppings. Cleaner, drier litter also helps keep birds feet healthier and minimizes the occurrence of problems associated with wet litter.</p> <blockquote> <p><strong>&ldquo;It just does what it is supposed to. That bucket is way better than what I was using before!&rdquo;&nbsp;</strong></p> </blockquote> <p style="text-align: justify;">We received a photo from a happy customer who purchased the&nbsp;<a href="http://www.hogslat.com/adjustable-chicken-drinking-bucket-with-3-nipples" target="_blank">poultry drinking bucket with 3 nipples</a>&nbsp;to put in his outdoor brooder. He is currently brooding a small group of mallard ducklings and&nbsp;a special&nbsp;wood duck duckling, which he rescued&nbsp;from the side of the road after seeing the rest of its flock get hit by a car while crossing a busy road. &ldquo;If you&rsquo;ve ever raised ducks before then you will agree they are much messier than chickens! The watering jars and founts I was using wouldn&rsquo;t last more than a few minutes before the ducks&nbsp;had knocked them over or made a mess in them,&rdquo; he said. &ldquo;Ever since I installed the bucket I can fill it up and it will last 2 or 3 days. I don&rsquo;t have to worry about whether my birds have water when I am gone during the day.&rdquo;</p> <p style="text-align: justify;">&nbsp;</p> <p style="text-align: justify;">If you&rsquo;re currently brooding chicks, getting chickens soon, or just need a better, cleaner way to keep fresh water available for your birds, visit the FARMSTEAD Equipment section at&nbsp;<a href="http://www.hogslat.com/farmstead-equipment" target="_blank">http://www.hogslat.com/farmstead-equipment</a>&nbsp;and purchase yours today!</p> <p style="text-align: justify;">&nbsp;</p> <p><img class=" wp-image-1927 size-large alignleft" src="/images/uploaded/wp-content/uploads/2015/05/CBP-Outdoor-Brooder-Setup-1024x576.jpg" alt="CBP Outdoor Brooder Setup" width="690" height="388" style="display: block; margin-left: auto; margin-right: auto;" /></p>urn:store:1:blog:post:93https://hogslat.com/farmstead-chicken-products-in-actionFARMSTEAD Chicken Products in Action!<p></p> <h2><img class="alignleft size-large wp-image-1896" src="/images/uploaded/wp-content/uploads/2015/05/Chicks-Under-Drinking-Bucket_Overhead-View_Touched-Up-1024x768.jpg" alt="Broiler chicks using drinking bucket." width="690" height="518" style="display: block; margin-left: auto; margin-right: auto;" /></h2> <h2 style="text-align: justify;">We’ve got chickens!</h2> <p style="text-align: justify;">This spring we added a few new items to our <a href="http://www.hogslat.com/farmstead-equipment" target="_blank">FARMSTEAD Equipment</a> product selection that have been very popular with our customers who raise small groups of chickens and other poultry. We always strive to provide the highest quality products for our customers and decided we would purchase and raise a small flock of broiler chickens to show everyone first hand how well the equipment we sell works.</p> <p style="text-align: justify;"> </p> <p style="text-align: justify;">So, we headed to the local farm supply store and picked up a dozen broiler chicks. We lucked out and ended up with a baker’s dozen, 13 birds in all. Until the chickens have feathered out and can move outside, we’re brooding them indoors. Chicks need a supplemental source of heat until they begin to grow feathers. Generally, the birds need to be kept at around 90°-95°F for the first week of life.</p> <p style="text-align: justify;"> </p> <p style="text-align: justify;">Our “brooder” is made from a small children’s swimming pool, which can usually be purchased for around $10 from your local big box store. The inside is lined with clean pine shavings and we put the chicken feeder on the floor to start out so the birds are easily able to locate their feed.</p> <p style="text-align: justify;"> </p> <p style="text-align: justify;">Many people use a <a href="http://www.hogslat.com/heat-lamps-and-bulbs" target="_blank">heat lamp and heat bulb</a> to provide the supplemental heat their birds need during their first few weeks of life. Using a heat lamp and bulb works very well, but for this flock we are using one of the new products we offer, the <a href="http://www.hogslat.com/comfort-heating-plate-for-chicks" target="_blank">Comfort Heating Plate for Chicks</a>, which you can see in the left side of the photo above. The great part about the Comfort Heating Plate is that it only draws 22 watts compared to the much higher wattage, 100-250 watt, that a conventional heat lamp uses. In addition to the energy savings you’ll realize, the Comfort Heating Plate substantially decreases the chances of an accidental fire that can occur when using a heat lamp.</p> <p style="text-align: justify;"> </p> <p><strong><img class="alignleft wp-image-1906 size-large" src="/images/uploaded/wp-content/uploads/2015/05/Chicks-Under-Comfort-Heating-Plate_Brightened-1024x768.jpg" alt="Chicks under Comfort Heating Plate for Chicks" width="690" height="518" style="display: block; margin-left: auto; margin-right: auto;" /></strong></p> <p style="text-align: justify;"><strong>In addition to the energy saving and safety benefits the Comfort Heating Plate provides, the chicks absolutely love it! </strong></p> <p style="text-align: justify;">That is because the heating plate is designed to mimic mother nature. When a hen hatches her chicks, she keeps them nestled under her for heat and protection. The chicks can gather under the mother hen for warmth and then from time to time come out for water, a bite to eat or just to stretch.</p> <p style="text-align: justify;">As you can see in this photo, the chicks took right to the heating plate like they would a mother hen and have no problem dozing off for a quick nap!</p> <p style="text-align: justify;">You probably noticed that some of the chicks are actually touching the plate’s surface. The chicks can fine tune their comfort level by contacting the surface, laying down, and moving from the middle to the edges.</p> <p style="text-align: justify;">The Comfort Heating Plate provides enough heat to keep the shavings underneath warm and inviting. When we set the brooder up before moving the chicks in, we tested the plate’s surface temperature as well as the temperature of the shavings beneath with an <a href="http://www.hogslat.com/the-heat-seeker-mid-range-infrared-thermometer" target="_blank">infrared thermometer</a>.</p> <p style="text-align: justify;"> </p> <p><img class="alignleft wp-image-1899 " src="/images/uploaded/wp-content/uploads/2015/05/Heating-Plate-Temperature-576x1024.jpg" alt="Infrared Thermometer Temperature of Heating Plate" width="389" height="692" style="display: block; margin-left: auto; margin-right: auto;" /></p> <p style="text-align: justify;"> </p> <p style="text-align: justify;">A perfect, consistent temperature for your birds, and peace of mind for you knowing that the Comfort Heating Plate for Chicks has dual safety features; a 0.5 Amp resistance fuse and 248°F temperature fuse.</p> <p style="text-align: justify;">If you’re planning on raising your own chickens this year, already have some chicks, or just want to take advantage of the Comfort Heating Plate’s safety features and energy savings, visit <a href="http://www.hogslat.com/comfort-heating-plate-for-chicks" target="_blank">http://www.hogslat.com/comfort-heating-plate-for-chicks</a> to purchase yours today!</p> <p style="text-align: justify;">Also, don’t forget to check back weekly as we’ll be documenting our experiences raising this flock as well as telling you more about the <a href="http://www.hogslat.com/adjustable-chicken-drinking-bucket-with-3-nipples" target="_blank">drinking bucket</a> and <a href="http://www.hogslat.com/hanging-chicken-feeders" target="_blank">hanging feeder</a> you see in the pictures above!</p>urn:store:1:blog:post:14https://hogslat.com/diy-gating-repairs-from-hog-slatDIY Gating Repairs from Hog Slat<p style="text-align: justify;">As my family and I traveled through Iowa last weekend, I couldn’t help but take notice of several finishing buildings that had been sitting empty for the last year or so. The curtains were down and pit fans running…they were&nbsp;filled with pigs again. Even though pigs are hard&nbsp;on equipment, nothing is harder on buildings than just sitting empty. Motors seize up; bolts and latches rust in place and the gating needs some general repair. To help with gating repairs, Hog Slat manufacturers a DIY product called&nbsp;<a href="http://www.hogslat.com/hog-slat-cut-and-weld-gating-panels" target="_blank" rel="noopener"><strong><em>Cut and Weld</em></strong>&nbsp;panels</a>. Cut and Weld panels allow producers to build gating “on-site” to the exact length needed.</p> <p style="text-align: justify;"><em>Cut and Weld</em>&nbsp;panels are available in two lengths; 6’-9’ and 9’- 12’ long.&nbsp;<em>Cut and Weld</em>&nbsp;panels are a standard 31 ½” high panel with one end upright tacked in place instead of welded solid.</p> <p style="text-align: justify;">You simply tap the upright loose and slide it along the horizontal rods until you reach the length desired.</p> <p><img class="size-full wp-image-38 alignnone" title="Cut and Weld" src="/images/uploaded/wp-content/uploads/2010/07/image1.bmp" alt="Cut and Weld" style="display: block; margin-left: auto; margin-right: auto;" /></p> <p style="text-align: justify;">You then weld the rods to the upright and top angle and cut off the excess.</p> <p><img class="size-full wp-image-39 alignnone" title="Cut and Weld" src="/images/uploaded/wp-content/uploads/2010/07/image2.bmp" alt="Cut and Weld" style="display: block; margin-left: auto; margin-right: auto;" /></p> <p style="text-align: justify;">&nbsp;</p> <p style="text-align: justify;">Then, depending on the application, you can choose from a full range of tabs, pipes, latches, etc. to complete the gate.

But after you buy a medicator, there are several things you can do to make sure you get the most bang for your buck from your equipment, and that it will last a long time.</p> <p style="text-align: justify;">When installing your medicator, be sure to plumb an 80 micron/200 mesh filter on the inlet side of the medicator. This will ensure that your medicator will be protected from poor water quality conditions that can potentially damage your unit. This will also protect any equipment you have downstream from the medicator, such as nipples, valves, and drinkers, from getting clogged and wearing out prematurely.</p> <p style="text-align: justify;">Also, make sure that your concentrate bucket is clean and free from debris that could get sucked up inside the medicator and jam the check valve. A good rule of thumb is to secure your hose at least 4&rdquo; up from the bottom of the stock tank so that heavy debris is not sucked up into the medicator.</p> <p style="text-align: justify;">Always be sure that your maximum flow rate stays within the maximum capacity of your medicator. Be sure to check with your medicator&rsquo;s manufacturer for specifications and for ways to determine flow rate. If you determine that your flow rate is higher than the maximum recommended, you may want to consider switching to a model with a higher maximum flow rate. Turning your water on slowly will gradually pressurize the system, helping to prevent a rush of water through the pipes that could be harmful to the equipment.</p> <p style="text-align: justify;">One of the most important things you can do to protect your medicator is to keep up the medicator&rsquo;s maintenance schedule, which you should be able to get from your medicator&rsquo;s manufacturer.</p> <p style="text-align: justify;">Flushing your medicator with clear water may be the single most important tip I can give.</p> <p style="text-align: justify;"><a href="http://www.hogslat.com/blog/medicator-best-practices/strainer-off-bottom-2" rel="attachment wp-att-54"><img class="size-full wp-image-54 alignnone" title="Strainer off bottom" src="/images/uploaded/wp-content/uploads/2010/07/Strainer-off-bottom1.jpg" alt="Strainer off bottom" width="150" height="113" /></a></p> <p style="text-align: justify;">Medicators are one of the most important weapons in your arsenal when it comes to keeping your animals as healthy as possible. By following these simple best practices, you&rsquo;ll make sure that your medicator continues to work hard for you for years to come.</p>urn:store:1:blog:post:16https://hogslat.com/swine-air-filtration-basicsSwine Air Filtration Basics<p style="text-align: justify;">While speaking with Perry Hartman, a sales rep for Hog Slat in Minnesota, I was brought up to speed on a topic that is quietly gaining some momentum in the industry…air filtration.   Southern Minnesota is an area that has seen rapid growth in pig numbers in the past several decades.  This high hog density has made herds there very susceptible to PRRS outbreaks.  To combat this, area producers have turned to air filtering to prevent herd infections.  Perry has been involved with 6 different projects and is currently working on the 7<span>th</span>.  These projects have ranged from a boar stud to a complete 5,000 head sow complex. Perry credits a close working relationship with Dr. Darwin Riecks of the Swine Vet Center in St. Peters, MN in making these projects a success.</p> <p style="text-align: justify;">Some of the leading technical information has come from an U of M test farm in Morris, MN.  There are three different buildings that have been outfitted with three different brands of filters and are tested for effectiveness against the PRRS virus.  From this initial research, it was determined the PRRS virus can be transmitted over 5 miles in distance and the greatest risk comes at temperatures between 40°-60° with a light 3-7 mph wind.</p> <p style="text-align: justify;">Using this information, a basic strategy has evolved around filtering the minimum air flow coming into the building.  A typical farrowing room has ceiling inlets for winter/transition air flow.   Minimum winter air flow can be effectively filtered by placing filtering boxes in the attic over the inlets.</p> <p style="text-align: center;"><br /><img class="size-full wp-image-61 alignnone" src="/images/uploaded/wp-content/uploads/2010/08/image1.bmp" alt="" width="335" height="221" /></p> <p style="text-align: center;">To permit installation and future service to the attic filtering system, an access is built in the end of the building gable with a stairway and locked door.</p> <p style="text-align: center;"><img class="size-full wp-image-62 alignnone" src="/images/uploaded/wp-content/uploads/2010/08/image2.bmp" alt="" width="239" height="381" /></p> <p style="text-align: center;">A catwalk is built inside to allow access to inlet filter boxes.</p> <p style="text-align: justify;"> </p> <p><img class="alignnone" src="/images/uploaded/wp-content/uploads/2010/08/image-9-150x150.jpg" alt="" width="250" height="250" style="display: block; margin-left: auto; margin-right: auto;" /></p> <p style="text-align: justify;">Galvanized boxes are installed between the rafters to mount the filters in. A pre-filter is installed to protect the filter from dust. The building structure needs to be examined for cracks that must be sealed and caulked to prevent unfiltered air from short circuiting the ventilation inlets.   By filtering the incoming air during the periods of highest disease threat (40-60°) some producers feel that temperatures above this will kill the virus effectively.</p> <p style="text-align: justify;">A complete filtration system goes past the basics and includes filtering the maximum air flow coming through the cool cell system.   Every situation requires careful calculation but a rough rule of thumb is to provide twice as much air filtering area as existing air inlets.</p> <p style="text-align: center;"><img class="alignleft size-full wp-image-64" src="/images/uploaded/wp-content/uploads/2010/08/image4.bmp" alt="" width="304" height="155" /><img class="size-full wp-image-65 alignnone" src="/images/uploaded/wp-content/uploads/2010/08/image5.bmp" alt="" width="225" height="155" /></p> <p style="text-align: center;">Retrofits for farrowing buildings have involved extending the roof line and adding a hallway to mount the filters in.   The filtering pads are installed in the new exterior wall and are protected by an outside curtain.</p> <p style="text-align: center;"><img class="size-full wp-image-66 alignnone" src="/images/uploaded/wp-content/uploads/2010/08/image6.bmp" alt="" width="356" height="232" /><img class="size-full wp-image-67 alignnone" src="/images/uploaded/wp-content/uploads/2010/08/image7.bmp" alt="" width="168" height="232" /></p> <p style="text-align: center;">Pre-filters are installed over the filters to prevent clogging of the system by dust and debris.</p> <p><img class="size-full wp-image-68 alignnone" src="/images/uploaded/wp-content/uploads/2010/08/image8.bmp" alt="" width="347" height="180" style="display: block; margin-left: auto; margin-right: auto;" /></p> <p style="text-align: justify;">A tunnel ventilation system, as used in many gestation and GDU buildings, require adding an extension on the gable end and creating an area that is large enough to mount the filter system. An “accordion” style arrangement of filter mounting is used in many cases to achieve the desired amount of filtering area.</p> <p style="text-align: justify;">This is brief overview of the basics for air filtering as it has evolved to date.  Again there is no “canned” solution as they are retrofits to existing ventilation systems.  Each must be examined carefully and correctly sized to prevent excessively high static pressures that could damage fan motors and the filters themselves.  Perry has invaluable knowledge of filtration systems gained through field experience over the last couple of years.</p>urn:store:1:blog:post:17https://hogslat.com/increased-ventilation-rates-pay-dividendsIncreased Ventilation Rates Pay Dividends<p>As every chicken grower knows, hot weather takes its toll on performance. Feed consumption and daily gain are difficult to maintain when temperatures reach and remain in the high 90s and above. Tunnel ventilation increases bird comfort resulting in improved performance. So is any type of tunnel ventilation good enough? Is there a return on adding fans for increased air speeds above the industry 550 fpm standard? Mike Lucariello, a Tyson grower from Wheaton, MO has a unique perspective on the question. Several years ago Mike remodeled six) 40’x400’ broiler houses to company specs including insulating the north side of the houses and adding insulated curtains to the south side. Fan power was increased to create a system capable of generating wind speeds of 550 feet per minute. Performance was excellent and his farm’s closeouts routinely ranked at the top. Last year Mike built two new 55’ x 600’ drop-ceiling houses. These houses feature improved side and ceiling insulation, energy efficient 52” Windstorm fans, Gro40 brooders and Tego tunnel doors. The wind speed in the new houses was calculated at 700 fpm. The first group was placed in these houses in February and the performance and energy use was excellent. The real test came this summer. A flock was placed on June 22. For the next six weeks the area experienced very hot and humid weather with temperatures staying in the 90s and moving into the 100s on a few occasions - the kind of weather that hurts bird performance and causes mortality to increase. The flock was caught and processed on August 2. Mike is on a competitive contract with Tyson so his performance is compared with other farms for the same week. <a href="http://www.hogslat.com/blog/increased-ventilation-rates-pay-dividends/poultry_graph" rel="attachment wp-att-80"><img class="alignleft size-large wp-image-80" src="/images/uploaded/wp-content/uploads/2010/09/poultry_graph-1024x162.jpg" alt="" width="590" height="94" /></a> These were excellent results especially considering that was an averaged total, (with 141,000 of the birds coming from the old houses and only 96,800 caught out of the newer houses with improved ventilation). Birds from the new house averaged 4.08 lbs. vs. 3.81 lbs. from the older houses. We would expect similar differences in Feed Conversion and Average Daily Gain. Another thing to consider is these are small birds... big 8 lb.+ birds would benefit even more from increased air speeds in the 700 fpm range. This winter is the time to take a look at retro fitting your existing ventilation system, especially if you have or are switching to big birds. Put a call in now to your local Georgia Poultry sales rep. They’ll visit your farm and help you put the cost of the retro together... it will pay big dividends in the heat next summer and put money back in your pocket.</p>urn:store:1:blog:post:18https://hogslat.com/protect-your-roof-this-winterProtect Your Roof this Winter<p>Last year the Midwest received an abnormal amount of snowfall and rain along with strong winds.

padding: 10px;" />As the swine industry searches for alternatives to stall gestation, another option has emerged and is in the process of being refined.  Stanchion Housing refers to short stall-like dividers that are added to open pen gestation to separate and protect the animals as they are fed.  It is a refinement over traditional open pens where sow are fed on the floor and group size must be limited to reduce fighting.</p> <p style="text-align: justify;">To date all the systems have been designed with standard gestation stalls in which the sows are weaned and remain until they are bred and preg checked.  Typically this would be about a 45 day inventory of the total sow numbers.</p> <p style="text-align: justify;"><img class="alignright" src="/images/uploaded/wp-content/uploads/2010/11/Angle-top-Stanchions-003.jpg" alt="" width="320" height="240" style="float: right; padding: 10px;" />Looking at the total number of animals in a breeding group, a decision can be made on total numbers of sows per pen.  Current stanchion systems range from 10 head per pen all the way up to over a hundred.  Many producers choose to break a farrowing group into two or three different pens as this allows for grading and sorting weaned animals by body score.  Placing sows in similar groups reduces fighting and allows for uniform feeding.</p> <p style="text-align: justify;">After total number of sows per pen is determined, the next design consideration is the amount of square footage per animal.  Current EU welfare regulations require 24 sq ft. and some producers have chosen to follow that guideline, but systems exist that range from this level all the way down to 17 sq ft./sow.</p> <p style="text-align: justify;">Two critical design elements have proved themselves in the existing layouts.  <img class="size-full wp-image-114 alignleft" src="/images/uploaded/wp-content/uploads/2010/11/Pen-Detail.jpg" alt="" width="320" height="256" style="float: left; padding: 10px;" />First, long narrow pens are preferred as this prevents a boss sow from blocking feed stanchions.  The second design feature is placing the stanchions head to head in the center of the pen rather than placing them along the alleys.  Because the stanchions are not in the alleys, the sows can be viewed from the rear during feeding for problems.  It also allows for easier animal movement in and out of the pens as the gates are not part of the stanchions.  In addition, the number of feed lines needed is reduced.</p> <p style="text-align: justify;">The first stanchion systems featured trickle feed equipment where the feed slowly dribbled in front of the sows at meal time, the idea being a slow placement of feed in front of the sows would hold them in the stalls and prevent boss sows from “wolfing down” their feed and moving up and down the line stealing feed.    In practice, the additional cost and upkeep of a trickle system did not justify its use and has been omitted on new installations.   Current systems use standard feed drops that dump the entire ration into stainless steel troughs or on a solid concrete floor.</p> <p style="text-align: justify;"><img class="alignright size-full wp-image-121" src="/images/uploaded/wp-content/uploads/2010/11/Angle-top-Stanchions-005.jpg" alt="" width="320" height="240" style="float: right; padding: 10px;" />Equipment used in a head-to-head layout consists of stanchions that are 40” tall and 19” long.  These dimensions protect the face and ears of the individual sow from aggressive pen mates.  Ideal width has been determined to be 20” as this prevents other sows from crowding in to steal feed.   Early systems used solid dividers; as we gained more experience with head-to-head systems,  the use of open dividers was adopted.   The Hog Slat equipment used to configure this layout is an adaption of our standard gestation stall which has been used throughout the industry for over 30 years.  The stanchions are constructed of solid horizontal rods with angle top and bottom rails, the entire unit bolts together with galvanized floor spacers and double top spacers for added stability. This style of stanchion fits completely with the standard 40” gestation penning used in the rest of the pen layout.   The result is a well-designed system that goes together without a great deal of “field fabrication”. AquaChief cup waterers are added at the rate of one per 11 animals to provide fresh water.</p> <p style="text-align: justify;"><img class="alignleft" src="/images/uploaded/wp-content/uploads/2010/11/Angle-top-stanchion-004.jpg" alt="" width="240" height="320" style="float: left; padding: 10px;" />Many of the stanchion systems are remodels, the layout of which has to be adapted to existing slat /solid configurations. If building new projects most producers opt for using total slats as this allows for more flexibility in the event of changes in the welfare regulations.</p> <p style="text-align: justify;">Stanchion systems require a high degree of stockmanship to operate successfully.  Boss sows must be culled ruthlessly and individual care of animals is more difficult than standard stall systems.  However, for many production systems, stanchions are a better alternative than Electronic Sow Feeding. Stanchions allow group housings of animals without the costs and high maintenance associated with ESF stations.</p> <p style="text-align: justify;">For more information please contact your local Hog Slat rep or contact us by email at <a href="mailto:frichards@hogslat.com">frichards@hogslat.com</a>.</p>urn:store:1:blog:post:20https://hogslat.com/chorelite-bootsthe-perfect-chore-bootChorelite Boots…the Perfect Chore Boot?<p style="text-align: justify;"><img class="alignright size-full wp-image-148" title="chorelite boots group" src="/images/uploaded/wp-content/uploads/2010/12/chorelite-boots-group.png" alt="" width="239" height="193" style="display: block; margin-left: auto; margin-right: auto;" /></p> <p style="text-align: justify;">Every now and then we stumble across a product or idea from another industry that we can adapt for use in the swine and poultry business.  Chorelite boots are one such product.</p> <p style="text-align: justify;">Designed for use as a deck boot in the off-shore fishing industry, it’s a unique product with features that will benefit swine producers and poultry growers as a chore boot for use inside of confinement buildings.</p> <p style="text-align: justify;">The first thing you will notice about the Chorelite is how extremely lightweight it is.  The Chorelite boot is constructed of EVA expanded rubber (similar to the material used in Crocs™ sandals) to create a lightweight but durable boot.</p> <p><a href="http://www.hogslat.biz/Chorelite_Boot.asp"><img class="alignleft size-full wp-image-147" title="Chorelite on scale" src="/images/uploaded/wp-content/uploads/2010/12/Chorelite-on-scale-copy-3.jpg" alt="" width="202" height="335" style="float: left; padding: 10px;" /></a>To give you an idea of how lightweight the Chorelite boot is; a typical rubber chore -type boot weights about 2 ½ lbs.  Contrast that to the Chorelite that weighs in at only <strong><em>10 ozs.!! </em></strong>Less weight equals less fatigue at the end of the day.</p> <p style="text-align: justify;">The Chorelite boot’s one-piece, molded construction means there are no seams to separate and leak.   The bottom tread is designed to be non-slip (remember the off-shore deck boot?) without being too deep preventing large amounts of muck from accumulating.</p> <p style="text-align: justify;">You will also notice the Chorelite boot is unlined making them easy to clean and disinfect.  You can wash them up, dunk them in a bucket of disinfectant and hang them upside down to dry.  They will be ready next time you walk back in the barn</p> <p style="text-align: justify;">When we first received the boots we were skeptical about their durability because they were so lightweight.   We put 10 pairs on the personnel of a local sow farm last July.   In six months of daily use they reported no tears or punctures in the boots…no leaks…..and the tread wear was excellent.</p> <p style="text-align: justify;">Now don’t get us wrong, even though we introduced this product during the winter, this boot wasn’t designed to keep anybody’s feet warm.  This is un-insulated boot for use inside of a confinement hog barn or chicken house.

Here are some tips&nbsp;to keep your houses running at peak efficiency.</strong></p> <p style="text-align: justify;"><strong>1) Bleed off water to control mineral content</strong></p> <p style="text-align: justify;">As water is circulated and evaporated in a pad system the concentration of minerals is increased.&nbsp; This is especially true in areas that have hard water with its higher levels of dissolved minerals. It is suggested that 5% to 10% of the circulated water should be continuously bled out of the system. Alternatively you can also dump and replace the sump tank water weekly. Products such as Scale-Stop or Cool-N-Kleen Cool Cell Descaler can be effective in controlling scale buildup for farms with very hard water when coupled with bleed off.</p> <p style="text-align: justify;"><strong>2) Check pH</strong></p> <p style="text-align: justify;">Desired pH level of the water should be between 6 and 9.&nbsp; The pH levels outside of the this range shorten pad life by leaching out the stiffening agents in the pad. You can alter the pH of the water by adding one of&nbsp;<img class="size-full wp-image-172 alignright" title="H2Pad" src="/images/uploaded/wp-content/uploads/2011/03/H2Pad-Upright-adj-clipped-FINAL.jpg" alt="" width="144" height="565" style="float: right; padding: 10px;" />the descaler agents listed above or Grower Select&rsquo;s Kool-Cell Kleen.</p> <p style="text-align: justify;"><strong>3) Eliminate dry spots on the pad</strong></p> <p style="text-align: justify;">Dry areas on the pads allow uncooled air to enter the building.&nbsp; Simply put,&nbsp; if the pad&rsquo;s not wet it&rsquo;s not cooling. Dry streaked areas on the pad are a clear sign that you have clogged holes in the distribution system.&nbsp; Remove the cover and unstop the clogged holes in the header system.&nbsp; It is a good practice to clean the distribution system by opening the ball valves and flushing water through at least once a month.</p> <p style="text-align: justify;"><strong>4) It&rsquo;s a pain&hellip;but you have to clean the filters</strong></p> <p style="text-align: justify;">Install a spin down water filter with a clear housing and 60 mesh screen on the system and keep it clean. It will prevent clogged distribution pipes and dirty pads. The poorer the water quality the more often the filters need to be cleaned. Installing a filter with a ball valve will simplify the chore.</p> <p style="text-align: justify;"><strong>5) Prevent algae growth</strong></p> <p style="text-align: justify;">Although H2PADs are treated with an fungicide and come with ProTech edging to prevent algae from adhering to the pad surface, this does not completely eliminate the problem.&nbsp; Treat the system&nbsp; water with a good preventive product like Bio-Stop or Grower Select&rsquo;s Kool-Cell Kleen to keep algae under control. In addition,&nbsp; the pads should be allowed to dry out once every 24 hours to improve the longevity of the pad.&nbsp; Program your ventilation system to allow the fans to continue to run awhile after the pad system is turned off at night.&nbsp; This will pull air through the system, drying the pads out and killing any algae spores.</p>urn:store:1:blog:post:22https://hogslat.com/comparing-17-year-old-slatsComparing 17 Year Old Slats<p style="text-align: justify;">I have sold or been involved with swine concrete slats for over 30 years.&nbsp; For the last 18 of those years I have represented Hog Slat products.&nbsp; I believe that our slats are the best in the industry and have the most consistent quality. But new slats all look good when they are getting unloaded off the delivery truck. What about when they are 5 years or 10 years or even older?</p> <p style="text-align: justify;">Last week I was at &nbsp;Hog Slat&rsquo;s production plant in Humboldt, Iowa taking pictures of slats.&nbsp; The plant manager, Dave Shiflett said &ldquo;You want to see some old slats that we pulled out of a barn recently?&rdquo;</p> <p style="text-align: justify;">&ldquo;Sure&rdquo;</p> <p style="text-align: justify;">So we go out behind the plant and he explained that we were called in to replace some slats from local production site.&nbsp; This particular site was built in 1994. One barn has slats produced by Hog Slat and the other barn has slats from a competitor.</p> <dl id="attachment_187"></dl> <div style="text-align: justify;"> <div id="attachment_187" class="wp-caption alignnone"><img class="size-medium wp-image-187 " title="comparing slats" src="/images/uploaded/wp-content/uploads/2011/05/slat-compar-top1-300x225.jpg" alt="" width="300" height="225" /> <p class="wp-caption-text">Comparing slats</p> </div> </div> <dl id="attachment_187"><dt></dt></dl> <p style="text-align: justify;">He said &ldquo;The slat on the left is a Hog Slat slat and the one on the right is from the competitor.&nbsp; Notice the difference in surface wear on each slat.&nbsp; The competitor&rsquo;s slat has rock showing because the top surface has been eaten or worn away.&nbsp; I grabbed our slat out of the other building that they were not replacing for comparison.&rdquo;</p> <p style="text-align: justify;">&ldquo;Interesting, but they&rsquo;re not from the same building&rdquo;</p> <p style="text-align: justify;">&ldquo;No but same site which means same water, same feed and same management.&nbsp; Pretty good comparison of 17 years old slats I would say&rdquo;</p> <p style="text-align: justify;">So we started talking about the reasons for the better wear on the Hog Slat product.</p> <p style="text-align: justify;">Dave said &ldquo;It&rsquo;s the denser concrete we use in our mix.&nbsp; Everybody that has ever poured any concrete knows the less water you use in mixing concrete, the harder, stronger concrete you get.&nbsp; The standard mix is a 4&rdquo; slump, which you have to use to be able to place and screed the concrete in the form.&nbsp; We use a ZERO SLUMP mix in our slats. Let me show you what I mean inside.&rdquo;</p> <p style="text-align: justify;">So we go inside and Dave has slump cone in which he places some of our concrete mix and pulls the cone. He adds water to an additional batch to represent a standard 4&rdquo; concrete mix.</p> <div style="text-align: justify;"><dl id="attachment_188"></dl> <div></div> <div id="attachment_188" class="wp-caption alignnone"><img class="size-medium wp-image-188 " title="concrete slump" src="/images/uploaded/wp-content/uploads/2011/05/slump1-300x225.jpg" alt="" width="300" height="225" /> <p class="wp-caption-text">concrete slump</p> </div> </div> <p style="text-align: justify;">&ldquo;Note how the concrete mix on the right has sagged down 4&rdquo; vs. the zero slump concrete on the right? All the rest of the slat manufacturers have to use a wetter mixture because they don&rsquo;t have equipment that allows them to work a drier mix. Like I said earlier less water means a stronger, denser concrete that wears better and holds up longer in the barns.&rdquo;</p> <p style="text-align: justify;">As the industry&rsquo;s production buildings get older this comparison bears keeping in mind.&nbsp; Most new slats look the same when they are placed in the barn and you really can&rsquo;t tell the difference from the outside. Buying slats for a new building or replacements in an existing structure is an important decision that producers should take under careful consideration.&nbsp; Looking at 17 year old slats is a chance to get some valuable insight that may help with that decision.</p>urn:store:1:blog:post:23https://hogslat.com/stop-pouring-money-down-the-pitStop Pouring Money Down the Pit<p style="text-align: justify;">With feed costs reaching an all time high, having the right feeder in your swine facility has never been more important.&nbsp; Historically American growers have enjoyed low feed costs compared to the rest of the world&rsquo;s producers.&nbsp; Because of the supply demand created by ethanol and production shortages, we may no longer enjoy this advantage in the world market. Our industry has seen a number of trends (fads?) in feeder design in the past years. Many of these feeders became popular because of their low cost. Large numbers were installed before they were adequately tested. As production data from these feeders was complied, many didn&rsquo;t meet industry standards for ADG and Feed Conversion.</p> <p style="text-align: justify;">The charts below show Agri-Stats Top 25&rsquo;s average for Feed Conversion for both Feeder to Finish and Wean to Finish operations.&nbsp; We can use them as a baseline to compare to potential savings that can be achieved with good, well designed feeders.</p> <p><img class="alignleft size-full wp-image-253" title="FC Chart" src="/images/uploaded/wp-content/uploads/2011/05/FC-Chart4.png" alt="" width="565" height="202" style="display: block; margin-left: auto; margin-right: auto;" /></p> <p style="text-align: justify;">Using these numbers let&rsquo;s compare potential savings on a typical 1,200 head finishing building with 20 feeders.&nbsp; For our example let&rsquo;s assume that the barn is showing an average feed conversion of 2.9 , achieves 2.4&nbsp; annual turns and replacing the feeders moves the FC to 2.6.</p> <p style="text-align: justify;">1,200 head x $24.64 saved per pig space =$29,568</p> <p style="text-align: justify;">To replace those 20 Feeders with Hog Slat 60&rdquo; feeders would cost $5,940.</p> <p style="text-align: justify;">To think of it another way, having efficient, easy-to-adjust feeders in a 1,200 finishing building saves $81 in feed wastage per day in our example.&nbsp; That means you would have to own the feeders for only 73 days to recoup your investment of $5,940!</p> <p><img class="alignleft size-full wp-image-218" title="feeder" src="/images/uploaded/wp-content/uploads/2011/05/feeder.png" alt="" width="263" height="233" style="display: block; margin-left: auto; margin-right: auto;" /></p> <p>Of the numerous brands available for replacement feeders why should Hog Slat feeders be your choice? Many of the top 25 production systems in the Agristats records are using Hog Slat feeders. The reasons are simple. For over 25 years, Hog Slat has produced a quality feeder without gimmicks or following fads.</p> <p style="text-align: justify;">The bolt together construction adds durability that you can&rsquo;t get with a welded feeder.&nbsp; Heavy weight hogs bang and push against feeders. &nbsp;Welded feeders don&rsquo;t have the ability to flex with the blows and stress cracks can develop.</p> <p style="text-align: justify;"><a href="http://www.hogslat.com/hog-feeders-finish-nursery-sow-piglet" target="_blank">Hog Slat feeders</a>&nbsp;have a deeper trough than most competitive brands and a feed saver lip preventing pigs from rooting feed out.</p> <p style="text-align: justify;">Hog Slat&rsquo;s box feeders provide higher storage capacity than most tube style feeders.&nbsp; The large storage volume contributes a safety factor for feed availability issues such as bin bridging, broken augers or motors and power failures.</p> <p><img class="alignleft size-medium wp-image-225" title="select-a-flow" src="/images/uploaded/wp-content/uploads/2011/05/select-a-flow1-300x219.png" alt="" width="300" height="219" style="display: block; margin-left: auto; margin-right: auto;" /></p> <p style="text-align: justify;">Precise management of the feeder adjustments is absolutely critical to achieving good feed conversions.&nbsp; Every Hog Slat feeder features our unique Select-A-Flow adjustment which gives producers the ability to make fine graduated changes in feed flow.&nbsp; Each numbered setting presents 1/16&rdquo; in feeder gate adjustment.&nbsp; And because each increment is numbered it is easy to set all the feeders in the barn to the same setting and repeat the settings from group to group.&nbsp;&nbsp; You can&rsquo;t get this kind of repeatability using feeders designed with crank type adjustments.</p> <p style="text-align: justify;">Hog Slat feeders have been the industry standard for the last 25 years.&nbsp; Replace your existing feeders and stop pouring money down the pit.</p>urn:store:1:blog:post:24https://hogslat.com/no-need-to-climb-a-feed-binNo Need to Climb a Feed Bin<p style="text-align: justify;">Every once in while you run across a product that is such a simple answer to a problem that you just have to say “Wow, why didn’t somebody think of that a long time ago?”</p> <p style="text-align: justify;">The severe winter of 2010 had us looking for an answer to monitor feed levels in bulk bins.

There are some existing  solutions like load cells and sonar systems, but we were looking for a simpler, less expensive way to check feed levels and protect against feed outages.</p> <p style="text-align: justify;">So we started looking into a ways to accomplish feed level monitoring…electronic sensors mounted in the bin walls, electric sensor cables hung in the bins, sonar bouncing devices from a fish finder…</p> <p style="text-align: justify;">One of the biggest problems that we kept coming back to was that all these methods required power be run to the bins to operate them.  Extra expense……harder to install…more of a chance for break downs and failure to occur.</p> <p style="text-align: justify;">Then along comes the Bin Flag….</p> <p><img class="aligncenter size-medium wp-image-359" title="bin flag " src="/images/uploaded/wp-content/uploads/2011/06/bin-flag-installed1-300x224.jpg" alt="" width="300" height="224" style="display: block; margin-left: auto; margin-right: auto;" /></p> <p style="text-align: justify;">A simple, mechanical device that uses a paddle inside the bin to rotate a sight cylinder to indicate when material is present.  Primarily used in industry applications to monitor levels in hopper for materials like sand, gravel, plastic beads…… it is the perfect device to measure feed levels for swine and poultry bulk bins.</p> <p style="text-align: justify;">It meets all the criteria we had established</p> <p style="text-align: justify;">1)      No electricity to operate</p> <p style="text-align: justify;">2)      Installs from the outside of the bin and you don’t need to lift the bin to install</p> <p style="text-align: justify;">3)      Low cost</p> <p style="text-align: justify;">4)      Flexible: basic method would be install a unit just above the cone to know when it is critical to order feed.  Producers also have the option of adding additional Bin Flags for more advanced monitoring.</p> <p style="text-align: justify;">5)      Very visible: big added bonus.  You can visually see the Bin Flag from up to 200 feet away.  You know in a glance from across the yard how much feed is in the bins….drive by a site and check feed levels from your truck seat. It doesn’t have to be cold for that to be a bonus.</p> <p style="text-align: justify;">There are more details online….go to <a href="http://www.hogslat.com/bin-flag-feed-level-indicator" target="_blank">http://www.hogslat.com/bin-flag-feed-level-indicator</a> to order today.</p> <p style="text-align: justify;">There’s even a way to hook up Bin Flag to your existing alarm to call you when feed levels drop to a critical level.  We’ll talk about that in the <a href="http://www.hogslat.com/have-the-bin-flag-call-you/" target="_blank">next blog</a> or so.</p>urn:store:1:blog:post:25https://hogslat.com/have-the-bin-flag-call-youHave the Bin Flag Call You<p style="text-align: justify;"><img class="aligncenter size-medium wp-image-378" title="100_0859" src="/images/uploaded/wp-content/uploads/2011/10/100_0859-300x225.jpg" alt="" width="300" height="225" style="display: block; margin-left: auto; margin-right: auto;" /></p> <p style="text-align: justify;">Okay I admit it…it has been awhile since we’ve posted a blog. But I have an excuse…We’ve been working on some new ad campaigns and new swine and poultry catalogs (<a href="http://www.hogslat.com/information-catalog-email-contact-request" target="_blank">which you can request a copy of here.</a>) But now we are back…ourlast blog was about the Bin Flag and at the end we mentioned a way to connect it to a phone alarm dialer.</p> <p style="text-align: justify;">When you pair the Bin Flag with a <a href="http://www.hogslat.com/1089-alarms" target="_blank">alarm phone dialer</a> you will receive a phone alarm whenever feed levels drop below the critical level.  Setting the Bin Flag up with most alarm systems is a pretty simple process.   Purchase the magnetic sensor for less than $20 (item #<a href="http://www.hogslat.com/magnetic-sensor-for-bin-flag-feed-level-indicator" target="_blank">HDL59065-952</a>) and screw it into the Bin Flag.  You then run common phone wire from the sensor to a contact on the phone dialer.   The alarm system will allow you to program a unique message that identifies each particular bin.</p> <p style="text-align: justify;">Really I’m not so sure this isn’t a more important feature than the visual part of the Bin Flag…normally you have to be at the building site and look at the Bin Flag. But with the Bin Flag connected to an alarm it calls you. So whether you are in the field, on the road, and wherever you have cell service you will be notified when a feed outage occurs and have to time to react and get feed ordered.</p> <p style="text-align: justify;">You can learn more about setting up the Bin Flag with the Sensaphone and Agri-Alert alarm systems by <a href="http://hogslat.com/images/products/manuals/bin-flag-sensaphone.pdf" target="_blank">going to our website and reading the manual</a> we have located under our Resources section.</p>urn:store:1:blog:post:26https://hogslat.com/yuppie-hill-poultryYuppie Hill Poultry<p><img class="alignleft size-large wp-image-815" src="/images/uploaded/wp-content/uploads/2011/11/Yuppie-Hill-sign-1024x768.jpg" alt="Yuppie Hill sign" width="345" height="258.5" style="display: block; margin-left: auto; margin-right: auto; padding: 15px;" />The Lein family’s start in the egg business began with 12 hens back in 1999. Those hens provided eggs for the family as well a few neighbors and friends.  Visitors to farm thought the hens had it so good they referred to them as “yuppie chickens”.  When Lynn started direct marketing eggs she adopted the brand name, Yuppie Hill Poultry. As the business grew, Lynn acquired the present farm on Potter Road and converted an existing dairy barn into a laying house for 3,000 hens.</p> <p style="text-align: justify;">“That first house was a lot of work.  We gathered the eggs, washed them and did the feeding all by hand. The air quality was poor and production never got above 70%” remarked Lynn.</p> <p style="text-align: justify;">In 2008, the family decided to increase production by constructing a new 50’ x 250’ flat deck house for 9,000 hens. Although the new system saved labor with automated feeding and egg gathering, the family researched other options before their next stage of expansion.</p> <p style="text-align: justify;">As Jay explained, “We were not totally satisfied with our conventional deck system.  We felt the environment could be better for the chickens.  In addition, we were spending a lot of time cleaning out the building between groups.  The extended down time between groups made it hard for us to supply our customers and reduced our income.”</p> <p style="text-align: justify;">Their research led them to Potter’s Poultry, one of the leading manufacturers of cage-free production systems.  After contacting Hog Slat rep Jason Billings, the group traveled to England to see firsthand the Potter’s System in use.</p> <p style="text-align: justify;">“We visited six commercial farms in four days and came away very impressed.” said Lyn “We were particularly interested in an aviary type system because the zoning restrictions on our farm forced us into putting as many chickens as possible in a limited floor plan.  The other aviary systems we had looked at were really just big cages. Potter’s has been building aviary systems for 20 years and has designed a true cage-free system that is the most open one on the market.”</p> <p style="text-align: justify;">Jay added “We liked what we saw and came home determined to copy the style of barns we had seen in England. The ventilation was excellent and it equipment was built extremely heavy with a lot of small features that make a big difference.”</p> <p style="text-align: justify;">After returning,  plans were finalized on 55’ x 245’ building with a center wall running the length of the building creating two individual rooms each capable of holding 8,900 hens. By combining this capacity with the first building the Leins will have three separate flocks.  Because no more than one room is ever out of production for cleaning, eggs are always available to supply customers.  Construction began in mid July and the first hens were placed October 3<span>rd</span>.</p> <p><img class="alignleft size-large wp-image-817" src="/images/uploaded/wp-content/uploads/2011/11/Yuppie-chicken-2-768x1024.jpg" alt="Yuppie chicken 2" width="690" height="920" style="display: block; margin-left: auto; margin-right: auto;" /></p> <p style="text-align: justify;">Colony nests are stacked two high along the center wall with the aviary facing it.  The AVINEST colony nests allow hens to gather in groups behind privacy curtain to lay their eggs. The system uses the original AstroTurf pads that are perforated to allow dirt to fall away ensuring cleaner eggs.    Cleaner eggs are also promoted by the automatic expulsion feature where the nest floors are lifted with a rack and pinion system gently moving the hens out of the nests at night time.</p> <p style="text-align: justify;">The aviary features perches where feed and water are available on multiple levels.  Two manure belts also run the length of the system.   On the other side of the aviary, opposite the nests, is a scratch area with doors that can be opened to an outside run.  The computer controlled ventilation system features chimney style fans linked with automated sidewall vents.</p> <p style="text-align: justify;">When I asked about the different lights installed in the building Jay explained “First the red lights above the boxes come on at 4:00 until 6:00 am with the nests’ floors dropping down to provide access to the nests.  At 5:30 the whole house fluorescents come on dim and gradually increase every 15 minutes until they are on full power.    Next the perch lights come on, then the lights on the second layer of the aviary come on and finally the floor lights are activated.  The floor lights are key to preventing floor eggs from being laid.  At night the order is reversed with boxes closing around 4:00 pm with the house lights going down at 7:00.  At 8:10 the bottom lights are turned off, the middle lights at 8:20 and the house lights are shut off at 8:30.  This entire sequence is automatically controlled by a master light control.”</p> <p><img class="alignleft size-large wp-image-818" src="/images/uploaded/wp-content/uploads/2011/11/Yuppie-conveyors_edited-1-628x1024.jpg" alt="Yuppie conveyors_edited-1" width="628" height="1024" style="display: block; margin-left: auto; margin-right: auto;" /></p> <p style="text-align: justify;">Egg collection system on the two-tier nest system is accomplished by the use of curved mini steel rod conveyers that bring the eggs to a single level.  From there another conveyer system moves the eggs to collection area where the eggs are inspected, packaged and cooled until delivery to customers.</p> <p style="text-align: justify;">Jay also called out the manure handling belts. “We feel that one of the biggest benefits of this system over our older building is the ability to remove the manure frequently.  Because a majority of the manure is deposited under the aviary perches, we are able to run the belts located under the aviary and dump them on to a cross belt where it is piled outside.”</p> <p><img class="alignleft size-medium wp-image-819" src="/images/uploaded/wp-content/uploads/2011/11/Lein-family-300x256.jpg" alt="Lein family" width="300" height="256" style="float: left; padding: 10px;" /></p> <p style="text-align: justify;">“We like our niche in the market” Lynn said when we discussing Yuppie Hill’s customers.  “We supply upper-end restaurants and grocery stores in Madison, Chicago and Sheboygan.  We provide a quality product produced by a family farm.  Demand keeps growing and this new facility will enable us do a better job supplying our customers.”</p> <p style="text-align: justify;">One final  point of interest at Yuppie Hill farm is the original dairy barn used for the first laying house has been converted again…into a restaurant that serves brunch every Sunday morning except the second weekend the month.  The second weekend is devoted to special Saturday night theme dinner of four to five courses with neighborhood chefs invited in to host the event.  The chefs prepare local foods paired with regional wines and beers.   The event is becoming quite popular with the last couple of dinners being completely sold out.</p>urn:store:1:blog:post:27https://hogslat.com/new-lease-on-life-for-broiler-housesNew Lease on Life for Broiler Houses<p style="text-align: justify;">Kip and Michelle Cullers took a hard look at their existing broiler operation and decided changes needed to be made. First put into operation in 1989, the six 22-year old buildings were in need of major renovation to qualify for premium payments.</p> <p style="text-align: justify;">After exploring their options with MoArk, a leading producer of specialty eggs, the Cullers next contacted Mike Lucariello who heads up Georgia Poultry&rsquo;s operations in the area.</p> <p style="text-align: justify;">Working with the existing 40&rsquo; x 400&rsquo; dimensions, Mike put together a layout designed to house 12,500 hens per building. The layout features two rows of Wadeken center belt nests set up on a flat deck of plastic slats with a lowered center scratch area. New chain feeders and the old drinker systems, outfitted with cups, were installed on the deck area between the nests and the exterior walls.</p> <p style="text-align: justify;">The ventilation system was upgraded with the addition of seven 52&rdquo; Windstorm fans and a 5&rsquo; x 55&rsquo; cool cell system on each side of the building. The system also unitizes the existing curtain system that can be manually activated during mild weather.</p> <p style="text-align: justify;">To complete the project, a 20&rsquo; x 40&rsquo; egg room was added to each building. The bulk of the egg collection is done in the morning with center belts moving the eggs to the end of the building where they are placed into flats, stacked on wheeled racks and moved to the egg cooler until pick up every Tuesday and Friday.</p> <p style="text-align: justify;">Kip commented, &ldquo;We had complete confidence in turning the project over to Mike. He&rsquo;s been in the chicken industry for a long time and has broiler and laying houses of his own. We are especially pleased with the way the ventilation system performed last summer. The tunnel system combined with the cool cell system kept the hens comfortable; in fact, we experienced no loss of production despite&nbsp;the&nbsp;record heat we had.&rdquo;</p> <p style="text-align: justify;">Kip continued, &ldquo;Michelle is responsible for the day-to-day operations on the farm. She does an outstanding job keeping up with the paperwork necessary for organic egg production. Plus she manages two full time employees and four part timers who gather eggs. I help out with repair and maintenance as the farming operation and travel allows.&rdquo; (In case you are wondering whether&nbsp;you have heard Kip&rsquo;s name before, you may have.&nbsp;<a href="http://www.farms.com/farmspages/expertsbio/tabid/293/default.aspx?newsid=34963&amp;authorid=173" target="_blank">He holds the record for soybean production at 160.6 bushels per acre</a>&nbsp;and travels worldwide speaking about his production methods).</p> <p style="text-align: justify;">To find out more contact us at 800-949-4647.

It really doesn&rsquo;t matter who built them, the quality of the metal or the insulation value&hellip;..if they have a metal ceiling you will eventually have some rust occurring. The most typical spots to see this are around the air inlets (cold air hitting a warm ceiling) and the along the outside walls where the ceiling metal is rolled over the knee braces (insulation tends to slide down). Over time this metal rusts and needs to be replaced.</p> <p style="text-align: justify;">Huge job! The plumbing and electrical lines have to be dropped, metal unscrewed, rips in the vapor barrier repaired, replace insulation and slide and fastened new metal sheeting into place.</p> <p style="text-align: justify;">Those kinds of repairs are the ones that tend to get put off indefinitely. That&rsquo;s where products from Vanberg Specialized Coatings come in. Rust Converter and EM-15 Epoxy Mastic are used to repair metal ceiling in place.</p> <p style="text-align: justify;">First, remove all the loose rust you can by scraping or pressure washing.</p> <p style="text-align: justify;">Second, apply Rust Converter to the visible rust areas. Rust Converter will neutralize the rust, you will see the rust turn from red to black in a couple of minutes.</p> <p style="text-align: justify;">Third, mix the two part EM-15 Epoxy Mastic together and either roll or paint it on the metal for a hard, moisture resistant coating that preserves the metal and protects it from further damage.</p> <p style="text-align: justify;">Vanberg produces a repair kit (EM15-1K) with everything you need to get started.

Great place to catch up with industry contacts and see the latest and greatest.</p> <p style="text-align: justify;">Stopped by the Potter&rsquo;s Poultry booth where Mike Button was quick to point out the new Seal of Approval presented to Potter&rsquo;s by the American Humane Association. The American Humane Association created the first welfare certification program in the United States to ensure the humane treatment of farm animals. Their Seal of Approval process verifies that equipment, housing designs and installation meet the standards of providing humane treatment in livestock production.</p> <p style="text-align: justify;">&ldquo;A very pleasant surprise&rdquo; said Mike.</p> <p style="text-align: justify;">Mike went on to comment, &ldquo;When we first started coming to this show we were viewed as kind of an oddity. Producers really questioned whether or not eggs could be produced like this on a commercial basis. As we put systems in and the producers achieved success, interest in our systems has grown.&rdquo;</p> <p style="text-align: justify;">&ldquo;We estimate only about 5% of the total egg output is being produced in cage-free systems here in the U.S. We think that this will grow to over 25%, similar to the amount produced in the U.K. There is a growing segment in the United States of consumers demanding eggs produced by more humane practices.&rdquo;</p> <p style="text-align: justify;">&ldquo;What&rsquo;s unique about Potter&rsquo;s Poultry is that we aren&rsquo;t a battery cage manufacturer that took the doors off the front and started offering them as cage-free systems.

Space Ray manufacturers some the best heating equipment on the market; Hog Slat and Georgia Poultry have carried their 40,000 Btu poultry brooder and tube heaters for years.</p> <p style="text-align: justify;">&ldquo;The Big Foot is a hybrid heater that combines the best qualities of the standard brooder and tube heaters,&rdquo; explained Space Ray&rsquo;s Wilf Jackson. &ldquo;Tube heaters have the advantage of less equipment to maintain but tend to produce a heating pattern that is oval in shape, while individual brooders produce a better heating footprint on the floor but require a producer to clean more pieces of equipment.&rdquo;</p> <p style="text-align: justify;">&ldquo;The heating footprint of the Big Foot is rectangular without gaps and the equipment can be installed close to the ceiling like a tube heater. Big Foot achieves its large, even footprint by utilizing a 19&deg; angle on the reflector shield eliminating problems with convective wash as the heat waves are directed towards the house floor.&rdquo;</p> <p style="text-align: justify;">Current plans are to offer the Big Foot in 60,000 and 90,000 Btu models and both single and dual stage ignition with emitter lengths of 15&rsquo; and 20&rsquo;.</p> <p style="text-align: justify;">The Big Foot is being field tested by Hog Slat in a local farm and Space Ray is having independent tests conducted starting in February. We look forward to reporting on the results of those tests in future blogs.</p>urn:store:1:blog:post:32https://hogslat.com/alternative-sow-housingAlternative Sow Housing<p>As the food industry responds to animal welfare issues, many producers have started&nbsp;to consider alternative options to stall-based gestation systems. We took a few moments to speak with Hog Slat&rsquo;s national sales manager, Fritz Richards, about group housing systems.<br /><strong>Can you describe the options available and the advantages and disadvantages of each?</strong><br />Hog Slat first took a hard look at the Electronic Sow Feeding or ESF systems. Sows are housed as groups and fed in stations that identify sows individually by means of RFID ear tags. This type of equipment seemed to offer slight advantages that would offset some of the management tools which producers would lose going to group housing from stalls. Such as the ability to feed animals as individuals and maintain dynamic farrowing groups. We looked at both domestic and international systems, touring and speaking with experienced growers. There were some differences that came to the forefront.</p> <p><strong>Like?</strong><br />This type of system is a major paradigm shift for US producers. The US industry has developed a very straight forward system of handling gestation sows. Sows are weaned into a stall, bred there and sow condition is managed by individual feeding. ESF is a completely different management style. First, the animals must undergo a two to four week training process with up to five percent of them eliminated as untrainable. Second, because computers, scanners, RFID tags and low voltage lines are necessary for ESF equipment a highly trained staff is required to operate the system&nbsp;successfully. With many production systems experiencing high turnover of farm staff, it becomes very difficult to perform the necessary maintenance and training.</p> <p><strong>Where do you see ESF working best?<br /></strong>Farms where the owner works in the unit every day and is able to maintain and repair the equipment in-house. The U.S. landscape is not like the situation we saw in Europe where as many as six service technicians are available in an area the size of a U.S. county. Getting timely repairs when the equipment is down should be an important consideration when considering ESF systems.</p> <p><strong>What other options have you looked at?</strong><br />Free Access Stalls. In this system, the sows are housed in groups but are provided with access to individual feeding stalls. The stalls have a lockout mechanism on the rear gate that allows sow access and prevents other sows from entering. She is able to exit the stall at any time to go back in the pen area. Most designs feature an option for the herdsman to lock the sows in the stalls for treatment. We feel this may be the ultimate sow housing system.</p> <p><strong>Are Free Access Stalls available from Hog Slat?</strong><br />We offer this equipment to producers, but, they need to remember&nbsp;that this is the most expensive option they can install. The square footage requirements per sow are high, (as much as 37 sq ft per sow) and the stalls with a locking mechanism are more expensive than a standard gestations stall.</p> <p><strong>What other options are available?</strong><br />Floor feeding in pens actually predates stalls. This system is designed with five to eight sows per pen, and the feed is dropped directly on the pen floor. This system is successful if managed correctly. Grouping of the sows by size is critical as the strongest animals tend to get the most feed. It is the lowest cost alternative to gestation stalls.</p> <p><strong>What seems to be the most popular option?</strong><br />Stanchions are the most popular system we see for new and remodel projects. This is group housing with short dividers or stanchions to protect the individual sow at feeding time. This design lends itself to a wide range of group sizes with a lot of flexibility in pen and building dimensions, which is important with remodel projects.</p> <p><strong>Why do you think it is so popular?</strong><br />Stanchion production methods adapt well to current U.S. production practices. A farm&rsquo;s current staff can manage a stanchion system because it utilizes the same feed delivery system and penning equipment as they are currently using.</p> <p><strong>What criteria are used in designing a stanchion system?</strong><br />The first decision is how many square feet per sow will be allocated. Obliviously, square footage in the building is expensive, and this can range from 17 to 24 square feet per animal. This is a business decision each producer must weigh against projected welfare regulations.<br />A group sizing of 10 to 20 head per pen is common. Equipment is standard 40-inch high rod panels with 18&rdquo; long divider stanchions, creating a feed space for each animal in the pen. The stanchions are open rod style set at 18&rdquo; to 21&rdquo; width. Experience has shown it is not necessary to use solid dividers on the side or front of the stanchion. The rod style protects the ears and head of the sow from aggressive animals and doesn&rsquo;t restrict air flow as much as solid panels. In addition, rod style penning is more cost effective and has a longer life span.<br />We also design a breeding area with stalls equal to 45 days worth of sow holding capacity. Sows are weaned into this area until bred and formed into gestation groups.</p> <p><strong>How is the stanchion system managed?</strong><br />Sows are fed using an automated feed system with individual drops. Sows anticipate each feeding and start lining up before the feed drops. You don&rsquo;t see much shuffling between stanchions as they become conditioned to eating their portion and realize the other feeding slots will not have feed after they finish. The earliest systems utilized a trickle feed system where over a longer time, small amounts of feed were dispensed to hold the sow at their feeding space. Trickle feeding was proven to be unnecessary and just added additional cost to the scheme.<br />While the sows are eating, a herdsman moves along the alley noting animals that are not at the feed trough. He can mark them for later treatment or movement to a hospital area.</p> <p><strong>Are there any disadvantages?</strong><br />Yes, animals cannot be individually fed. Sows that &ldquo;fall out&rdquo; of a group because of sickness or injury have to be removed to a hospital pen or stall. Despite the disadvantages, this has been a popular choice for many producers desiring&nbsp;to move into group housing.</p> <p><strong>How many stanchions have been installed by Hog Slat?</strong><br />Hog Slat has built and installed over 150,000 spaces of stanchion housing in the U.S., from individual farms up to large production systems. We have gathered a lot of field experience completing those projects and can help any producer considering group housing systems.</p>urn:store:1:blog:post:33https://hogslat.com/changing-fan-v-beltsChanging Fan V-belts<p style="text-align: justify;">Just saw some interesting info from Billy Farmer. Billy is the store supervisor in Georgia, and had just attended the 2012 Poultry Tunnel Ventilation Workshop at the University of Georgia. They always put out great technical informational at their workshops and this piece caught my eye.&nbsp; We all know that we should change v-belts on belt drive fans when they get worn but&hellip;.why?</p> <p style="text-align: justify;">V-belts don&rsquo;t actually stretch as is commonly referred. They get thinner as they wear. Because they get thinner, the belts will start to ride lower in the pulley groove. When this happens it&rsquo;s just like the pulley becoming smaller. As the fan spins slower it&nbsp;moves less air. CFM delivery is directly proportional to the fan speed. Spin the fan 10% slower and it moves 10% less air. Reducing the CFM&nbsp;capacity of a building by 10% can spell disaster in terms of pig and broiler performance during the heat of the summer.</p> <p style="text-align: justify;">How do you know when to replace a V-belt?&nbsp;</p> <p><img class="alignleft size-full wp-image-468" title="v-belt" src="/images/uploaded/wp-content/uploads/2012/05/v-belt.png" alt="" width="173" height="128" style="float: left;" /></p> <p style="text-align: justify;">A quick visual check will determine if &nbsp;a V-belt is worn and needs to be replaced. If the belt is riding above the pulley groove, it is doing its job. If the belt is bottomed out in the groove and/or riding below the top of the groove, it&rsquo;s time to replace the V-belt.</p> <p style="text-align: justify;">While you have the V-belt off, you should take time to inspect to the pulley itself. A new pulley has a sharp V-shaped groove. A pulley that is more U-shaped is worn and needs to be replaced before you put on the new V-belt.</p> <p><img class="size-full wp-image-484 aligncenter" title="old pulley" src="/images/uploaded/wp-content/uploads/2012/05/old-pulley2.png" alt="" width="128" height="70" style="display: block; margin-left: auto; margin-right: auto;" /><br /><img class="aligncenter size-full wp-image-483" title="New pulley" src="/images/uploaded/wp-content/uploads/2012/05/New-pulley3.png" alt="" width="128" height="69" style="display: block; margin-left: auto; margin-right: auto;" /></p> <p style="text-align: justify;">To make the job of replacing V-belts less expensive, Hog Slat developed our own line of V-belts called GroBelts. They are constructed of compressed rubber embedded with low stretch nylon cords. Hog Slat and Georgia Poultry stores carry a complete selection of the most popular sizes in stock. If you can&rsquo;t make it to a local store, you can also order on line at&nbsp;<a href="http://www.hogslat.com/v-belts-grobelt-drive-belts" target="_blank">http://www.hogslat.com/v-belts-grobelt-drive-belts</a>&nbsp;and we&rsquo;ll ship them directly to your door.</p> <p><img class="aligncenter size-full wp-image-496" title="grobelt" src="/images/uploaded/wp-content/uploads/2012/05/grobelt.png" alt="" width="214" height="100" style="display: block; margin-left: auto; margin-right: auto;" /></p>urn:store:1:blog:post:34https://hogslat.com/2012-world-pork-expo260-lb-burgers-2000-bin-whackers-and-esf2012 World Pork Expo…260 lb. burgers, $2,000 bin whackers and ESF.<p style="text-align: justify;">The 2012 Pork Expo is in the books.&nbsp; Great weather this year and great food.&nbsp; Especially the 260 lb pork burger Vinny and crew from Hog Slat cooked up.&nbsp; This wasn&rsquo;t just an inedible gimmick either&hellip;..the slice I had was very good.</p> <p style="text-align: justify;">Walking around the trade show, I noticed there were a few companies with products to address the bin bridging and feed outage problems caused by using DDGS and other alternative feed ingredients&hellip;&hellip;mechanical bin whackers in other words. One rep explained that his product was a much better choice than his competitor&rsquo;s model and &ldquo;ours is only about $1200 compared to theirs at $2000.&rdquo; Wow. The price of the anti-bridging device is almost as much as the bin.</p> <p style="text-align: justify;">Quite a few companies displayed their version of Electronic Sow Feeding (ESF). &nbsp;&nbsp;One says each feeding station will handle 60-65 sows, the next guy&rsquo;s will handle 300.&nbsp; &nbsp;All the computerized systems are easy to use; intuitive I believe was the term they used. &nbsp;Everybody had a &ldquo;system expert&rdquo; who probably lives several states away from your farm.</p> <p style="text-align: justify;">Remember when everyone had to hook up their ventilation controls up to a computer in their office? Going to run the barn from the house was the idea. Most ended up with the plastic cover left on after a month or two. A couple of years ago, sorting scales were going to change the way finishing pigs were raised. Most of those are sitting outside rusting away&nbsp;now.</p> <p style="text-align: justify;">No doubt some producers will successfully adopt ESF technology. One thing is guaranteed, not all the companies offering ESF will be at this show five years from now. Choose carefully.</p>urn:store:1:blog:post:35https://hogslat.com/sort-barn-remodelSort Barn Remodel<p style="text-align: justify;">In 2005 Dustin Anderson and Paul Anderson came to an agreement on a &nbsp;venture allowing Dustin to quit his job at the local coop and farm full time. Besides farming 1,500 acres, Paul also serves as a member of the Minnesota House of Representatives and wanted to devote more time to his political career. &nbsp;&nbsp;Part of the agreement included each of them constructing a 2,498 head finishing house with Dustin managing the sites.</p> <div id="attachment_511" class="wp-caption aligncenter" style="text-align: justify;"><img class="size-medium wp-image-511" title=" " src="/images/uploaded/wp-content/uploads/2012/06/100_1036-300x225.jpg" alt="" width="300" height="225" /> <p class="wp-caption-text">original sort barn</p> </div> <p style="text-align: justify;">Dustin explained &ldquo;The integrator that we fed with at the time spec&rsquo;ed a sort barn system and we constructed the facilities according to the&nbsp;standard plan. The sort barn was different from what we were used to managing. &nbsp;The pigs had to be trained to go through the sorting scale for about three weeks, we had to force them through until they learned where the feed was. Even with that type of training there always seemed to be a handful of pigs that refused to go through the sorting scale. They would literally starve themselves to death.&nbsp; In addition, anytime the pigs became sick, the whole barn would refuse to go into the food court.&nbsp; We would then have to open up the gates and give them access to the feeders. After a couple of days of that, we would have to retrain them all again!&rdquo;</p> <p style="text-align: justify;">&ldquo;Our death loss was a little higher than we would have like because it was hard to treat individual pigs. The pigs had a half a barn to run around in and giving a shot or separating a pig from the group was a job. The one thing I will say is that the pigs loaded for market like a dream. I could literally load a semi in 15 minutes. The pigs were accustomed to moving around in large pens, and they would run right up into the truck.&rdquo;</p> <p style="text-align: justify;">Dustin continued, &ldquo;Several years ago we changed companies and quickly found out our feed conversion and rate of gain were not measuring up.&nbsp; In order to compete, we felt we needed to convert to a more typical pen layout.</p> <p style="text-align: justify;">&ldquo;We called our local Hog Slat rep, Wade Finch, when we got serious about doing the retro.&nbsp; Wade measured up the rooms and met with us several times before we decided on a final layout.&nbsp; We set up the rooms with a center alley and 18 pens measuring 18&rsquo;8&rdquo; wide X 23&rsquo;9&rdquo; long holding 65 head each.</p> <p><img class="alignnone wp-image-515" title="layout drawing" src="/images/uploaded/wp-content/uploads/2012/06/layout-drawing-212x300.jpg" alt="" width="259" height="367" style="display: block; margin-left: auto; margin-right: auto;" />&nbsp; &nbsp; &nbsp;<img class="alignnone wp-image-518" title="100_1052" src="/images/uploaded/wp-content/uploads/2012/06/100_10521-300x225.jpg" alt="" width="340" height="255" style="display: block; margin-left: auto; margin-right: auto;" /></p> <p style="text-align: justify;">In addition, we created four &ldquo;sick pens&rdquo; that are 9&rsquo;4&rdquo; wide.</p> <p><img class="alignnone size-medium wp-image-528" title="100_1059" src="/images/uploaded/wp-content/uploads/2012/06/100_1059-300x225.jpg" alt="" width="300" height="225" style="display: block; margin-left: auto; margin-right: auto;" /></p> <p style="text-align: justify;">We also added extra gating by the feeders so we can shut off the front of the pen and presort for load out.</p> <p><img class="alignnone size-medium wp-image-529" title="100_1053" src="/images/uploaded/wp-content/uploads/2012/06/100_10532-300x225.jpg" alt="" width="300" height="225" style="display: block; margin-left: auto; margin-right: auto;" /></p> <p style="text-align: justify;">It took a lot of cutting and welding, but we were able to utilize most of the existing gating, feed system and watering equipment for the retro.&rdquo;</p> <p style="text-align: justify;">Justin was just starting to sort pigs out of the first remodeled barn the day of my site visit.&nbsp; When I asked about the results he replied, &ldquo;We would typically start to sell out of the old system after 18 weeks and finish up with the last ones going out at 22 weeks. We&rsquo;ll start selling the first group out of the remodeled barn at 13 weeks, and I&rsquo;m sure the last pigs will be gone at&nbsp;15 weeks. Chores are much easier; I can see all the pigs and treat sick ones without having to chase them around.&rdquo;</p> <p style="text-align: justify;">&ldquo;Now that I see the results, I wish I would have done it several years ago!&rdquo;</p>urn:store:1:blog:post:36https://hogslat.com/galvanized-metal-roof-repair-with-amc-100lGalvanized Metal Roof Repair with AMC-100L<p style="text-align: justify;">90 degrees, bright sunshine, no rain in the forecast and a light wind; perfect conditions for a firsthand look at roof repair.&nbsp; &nbsp;Last winter I sat in on a training session with Vanberg Specialized Coatings when they covered the basics on their exterior metal coating product,&nbsp;<a href="http://www.hogslat.com/vanberg-coatings-amc100l-urethane-coating" target="_blank">AMC-100L or Aluminum Moisture Cure Urethane</a>.&nbsp; The results in the training labs were impressive, and I wanted to get some field experience using the product.</p> <p style="text-align: center;"><img class="alignnone size-medium wp-image-541" title="100_0999" src="/images/uploaded/wp-content/uploads/2012/06/100_0999-300x225.jpg" alt="" width="300" height="225" /></p> <p><img class="alignnone size-medium wp-image-540" title="100_0998" src="/images/uploaded/wp-content/uploads/2012/06/100_0998-300x225.jpg" alt="" width="300" height="225" style="display: block; margin-left: auto; margin-right: auto;" /></p> <p style="text-align: justify;">The site chosen was not a livestock building, but a storage building erected in 1968.&nbsp; The 44 year old galvanized roofing was structurally sound but was starting to show large areas of surface rust.&nbsp; &nbsp;I greeted Jim and Steve from Vanberg Coating, and we started on the process.</p> <p><img class="alignnone size-medium wp-image-542" title="100_0996" src="/images/uploaded/wp-content/uploads/2012/06/100_0996-300x225.jpg" alt="" width="300" height="225" style="display: block; margin-left: auto; margin-right: auto;" /></p> <p style="text-align: justify;">First they sprayed the roof down with a power washer to remove any dirt, bird droppings or loose rust.&nbsp; Any areas with heavy rust were hit with a wire brush and loose nails were hammered down.&nbsp; Once the roof was dry, we moved on to the next step.</p> <p><img class="alignnone size-medium wp-image-543" title="100_1009" src="/images/uploaded/wp-content/uploads/2012/06/100_1009-300x225.jpg" alt="" width="300" height="225" style="display: block; margin-left: auto; margin-right: auto;" /></p> <p style="text-align: justify;">The second step of the process was to apply&nbsp;<a href="http://www.hogslat.com/vanberg-specialized-coatings-rust-converter" target="_blank">VSC Rust Converter</a>&nbsp;to the rusty spots.&nbsp; Rust Converter chemically changes rust to a stable, insert compound.&nbsp; Jim poured the Rust Converter into a pump sprayer and applied it to the rust spots that Phillip rolled out behind him.&nbsp; Steve finished the process by sweeping the semi-dried surface lightly with a broom to smooth out any bubbles.</p> <p><img class="alignnone size-medium wp-image-545" title="100_1017" src="/images/uploaded/wp-content/uploads/2012/06/100_1017-300x225.jpg" alt="" width="300" height="225" style="display: block; margin-left: auto; margin-right: auto;" /></p> <p style="text-align: justify;">The results were a little surprising.&nbsp; In the training demos, the samples that we applied the Rust Converter turned almost immediately jet black.&nbsp; On this roof, the color was more of a dark red with black edges.

When mats are used they are placed under the feeders, the gating is installed, and the installation is complete. With Armor-Rock, the feeders and gating are completely installed and then the feeders must be removed.&nbsp; The epoxy is mixed, placed on the flooring and allowed to dry.&nbsp; After the Armor-Rock cures, the feeders are replaced in the gating. &nbsp;&nbsp;Because of the extra labor the Armor-Rock option is not offered by most contractors.</p> <p style="text-align: justify;">The choice is yours to make.&nbsp; Chose the Ultimate Slat Saver with Armor-Rock and do it once or chose standard slat mats and fix it later.&nbsp; You can pick up Armor-Rock at any Hog Slat store or purchase it on line at&nbsp;<a href="http://hogslat.com/armor-rock-kit">http://hogslat.com/armor-rock-kit</a></p>urn:store:1:blog:post:38https://hogslat.com/sowmax-is-just-like-having-a-bunch-of-mini-feed-bins"SowMAX is just like having a bunch of mini feed bins!"<p style="text-align: justify;">I recently caught up with Mark Daughtry of Prestage Farms in North Carolina to discuss his experience with&nbsp;<a href="http://www.hogslat.com/sowmax-feed-dispenser" target="_blank"><strong>SowMax</strong>&nbsp;farrowing ad lib feeders</a>.&nbsp; Mark is the Sow Production Manager in North Carolina and oversees about 55,000 sows.&nbsp; He quickly corrected my terminology regarding the&nbsp;<strong>SowMAX</strong>.</p> <p style="text-align: justify;"><img class="alignnone size-medium wp-image-603" title="sowmax " src="/images/uploaded/wp-content/uploads/2012/07/sowmax-adjusted-pix-235x300.jpg" alt="" width="235" height="300" style="float: left; padding: 10px;" /></p> <p style="text-align: justify;">&ldquo;First of all&hellip;&rdquo; Mark said, &ldquo;the SowMAX is not a sow feeder.&nbsp; It&rsquo;s a feed storage device that delivers feed to the sow on demand. It&rsquo;s like having a bunch of&nbsp;<strong><em>MINI FEED BINS&nbsp;</em></strong>sitting above the feeders ready to deliver fresh feed on demand.</p> <p style="text-align: justify;"><strong>&ldquo;<em>I&rsquo;m not sure exactly what you mean</em>.&rdquo;</strong></p> <p style="text-align: justify;">Look I&rsquo;ve been working with sow herds for 24 years in one way or another. The&nbsp;<em>BIGGEST&nbsp;</em>challenge I&rsquo;ve faced in that time has been training farrowing house personnel to feed lactating sows.&nbsp; It is extremely difficult to feed sows correctly by hand.</p> <p style="text-align: justify;">Sows are individuals and&nbsp;depending on their genetic makeup some sows are capable of eating much more feed on a daily basis than the group.&nbsp; If you were to&nbsp;look at daily feed intake per sow, you would see a normal bell curve.&nbsp; The bulk of sows will eat somewhere between 18-22 pounds per day, but some of those gals will eat as high as&nbsp;<em><span>30 pounds a day!</span></em>&nbsp;Those are the sows that normally don&rsquo;t get fed correctly with hand feeding.</p> <p style="text-align: justify;">If we decide that 20 Lbs is all we will ever feed any sow, then those high appetite sows are going to get short changed.&nbsp; Those are the sows that&nbsp;will typically wean&nbsp;desirable large litters of heavy pigs.</p> <p style="text-align: justify;">I like to think of today sows as being like high performance race cars.&nbsp; If we don&rsquo;t fuel up a race car, it will not run.&nbsp; Same with sows, they are capable of high performance as far as producing large numbers of pigs, but we have to get the feed/fuel in them.</p> <p style="text-align: justify;"><strong><em>How does that change with SowMAX?</em></strong></p> <p style="text-align: justify;">SowMAX allows us to feed sows to full appetite without guess work.&nbsp; Our feeding regiment in farrowing goes like this:</p> <p style="text-align: justify;">For three days prior to farrowing we feed four pounds of feed through the SowMAX.&nbsp; We instruct the farrowing personnel to place two pounds, twice a day in the SowMAX hopper.&nbsp; This gets them up each time and gets them accustomed to activating the trigger lever on the SowMAX.</p> <p style="text-align: justify;">After farrowing, we continue to hand feed for two more days.&nbsp; On day three, we fill them up and monitor feed disappearance.</p> <p style="text-align: justify;"><strong><em>Feed disappearance? What does that mean?</em></strong></p> <p style="text-align: justify;">Simply put it&nbsp;means that we fill the SowMAX up twice a day and look the amount feed that is gone in the hopper.&nbsp; As long as the sow is eating over half of that amount we just fill it up again and go on.&nbsp; We are only concerned with the sows that aren&rsquo;t eating; that&rsquo;s the one that&rsquo;s having trouble and needs our attention.</p> <p style="text-align: justify;"><strong><em>&ldquo;You know Mark, feed is very expensive; what about a producer&rsquo;s concern that SowMAX may be getting more feed into the sows but that it&rsquo;s also wasting more feed?&rdquo;</em></strong></p> <p style="text-align: justify;">Our experience has shown the exact opposite.&nbsp; We waste less feed with SowMAX than hand feeding, and that&rsquo;s easy to figure out.&nbsp; With hand feeding if you guess wrong and put more feed in the feeders than she can eat, it spoils and you end up dumping it out.&nbsp; The&nbsp;<strong>SowMAX</strong>&nbsp;delivers fresh feed to the feeders&hellip;.on demand&hellip;.whenever a sow is ready to eat.&nbsp;&nbsp; Human judgment is eliminated&hellip;.we don&rsquo;t have to try and outguess mother nature. Again, we have those MINI FEED BINS sitting there ready to deliver feed whenever she&rsquo;s ready to eat.</p> <p style="text-align: justify;"><strong><em>Do you have farms with other types of systems?</em></strong></p> <p style="text-align: justify;">Yes, we have automatic systems where feed is dumped from drops into the feeders several times a day.&nbsp; There is less physical labor but it really isn&rsquo;t any better than hand feeding.&nbsp; You still have to guess on the amount of feed each sow will consume each day.&nbsp; Plus, as the systems get older they take more maintenance; it seems like we are always fixing a switch or replacing a motor.&nbsp;SowMAX works everyday; no timers, no motors, no switches, nothing to wear out.</p> <p style="text-align: justify;">With SowMAX, we fill the hopper, and we have some flexibility if something goes wrong.&nbsp; In a dire emergency, we still have almost a day&rsquo;s worth of feed storage at each hopper.&nbsp; We have other systems that use a plastic tube and have almost no storage.&nbsp; We have a lot more cushion with SowMAX than the other systems.</p> <p style="text-align: justify;"><strong><em>So with SowMAX, you are able to &ldquo;fuel up the race cars&rdquo; What differences do you see in performance?</em></strong></p> <p style="text-align: justify;">First, there are only two things that make milk, feed and water.&nbsp; A sow produces more milk per body weight than a milk cow.&nbsp; Can you image a dairyman limit feeding a milk cow?&nbsp; That would never happen, yet we expect a sow to produce to her full genetic potential on limit feeding!&nbsp; SowMAX allows us to fully feed&nbsp;sows according to their individual appetite and they produce heavier litters.</p> <p style="text-align: justify;">Second, we quit condition scoring sows coming out of the farrowing crates that are using SowMAX.&nbsp; Rarely would we have a Two score, they consistently scored as Threes. Because of their better body condition rebreeding is improved.</p> <p style="text-align: justify;">We have SowMAX in about 5,000 crates in North Carolina.&nbsp; You can bet that any updates or remodels that we do in the future will include SowMAX feeders also.</p> <p style="text-align: justify;">To learn more go to&nbsp;<a href="http://hogslat.com/sowmax-feed-dispenser">http://hogslat.com/sowmax-feed-dispenser</a>&nbsp;on our web store.</p>urn:store:1:blog:post:39https://hogslat.com/how-complicated-does-feeding-a-sow-need-to-beHow Complicated Does Feeding a Sow Need to Be?<p style="text-align: justify;">Ever notice how some people or companies try to make a job more difficult than it has to be?</p> <p style="text-align: justify;">Today I read an article about a show case farm with an &nbsp;integrated computer system including electronic sow feeding.&nbsp; There is a picture showing a hand held computer programming in the amount of feed that a sow will receive according to its body condition score.</p> <p style="text-align: justify;">Looks like a complicated and expensive system that isn&rsquo;t any more effective than hand feeding.&nbsp; If the computer based delivery system puts more feed in front of the sow than she can eat then it spoils and&nbsp;if the system puts in too little she doesn&rsquo;t get the nutrients she needs for full milk production.</p> <p><img class=" wp-image-611 aligncenter" title="IMG_0123 (533x800)" src="/images/uploaded/wp-content/uploads/2012/07/IMG_0123-533x800-199x300.jpg" alt="" width="199" height="300" style="float: left; padding: 10px;" /></p> <p style="text-align: justify;">Compare this to feeding with a&nbsp;<a href="http://www.hogslat.com/sowmax-feed-dispenser" target="_blank">SowMAX</a>.</p> <p style="text-align: justify;">You fill the hopper.&nbsp; The sow activates the lever and eats as much or as little as she wants&hellip;.whenever she wants&hellip;&hellip;night or day.</p> <p style="text-align: justify;">No guess work.&nbsp; No wasted feed.&nbsp; No under fed animals.</p> <p style="text-align: justify;">In the same e-mag there was also an advertisement describing an ad lib sow feeder that looked a lot like the SowMAX.&nbsp; One crucial difference though, it described the product as having a &ldquo;timer that&nbsp;dispenses food at desired&nbsp;intervals over a 24 hour period&rdquo;</p> <p style="text-align: justify;">Who&rsquo;s desired time, yours or the sow&rsquo;s?&nbsp;&nbsp; Why would you use a timer and motor instead of a lever?&nbsp; &nbsp;Most importantly this feeding dispenser still requires the operator to make a decision on the amount of feed that is metered out in 24 hours.</p> <p style="text-align: justify;">Again, same story. Feed too much and you&rsquo;ll get spoilage or feed too little and the sows produce less milk.&nbsp; &nbsp;The SowMAX system lets the sow make the decision instead of a human operator.</p> <p style="text-align: justify;"><strong>SowMAX is the best Ad Lib Feeder on the market today.</strong></p> <ul style="text-align: justify;"> <li>All stainless steel construction instead of plastic or nylon which means it lasts longer.</li> <li>Simple mechanical activation instead motor and switches which means no parts to replace.</li> <li>Eliminates guess work in determining the amount of feed which means the sows are always feed correctly.</li> </ul> <p style="text-align: justify;">To learn more about SowMAX go to&nbsp;<a href="http://hogslat.com/sowmax-feed-dispenser">http://hogslat.com/sowmax-feed-dispenser</a></p>urn:store:1:blog:post:40https://hogslat.com/ad-lib-sow-feeder-that-saves-feedAd Lib Sow Feeder That Saves Feed?<div id="attachment_618" class="wp-caption alignleft" style="text-align: justify;"><img class="size-medium wp-image-618" title="IMG_0123 (533x800)" src="/images/uploaded/wp-content/uploads/2012/08/IMG_0123-533x800-199x300.jpg" alt="" width="199" height="300" /> <p class="wp-caption-text">SowMAX ad lib dispenser</p> </div> <p style="text-align: justify;">Claiming an Ad Lib Sow Feeder can save feed may seem like a contradiction of terms.&nbsp; How can allowing a sow unlimited access to feed save money on feed?</p> <p style="text-align: justify;">It&rsquo;s simple really&hellip;sows are individuals with different eating and consumption patterns.&nbsp; Some days they&rsquo;re extra hungry, some days they&rsquo;re not.

He replied, &ldquo; Their general reaction is Hog Slat builds durable products that represent a good value.&nbsp; They like the common sense design and how it is incorporated into the overall building layout.&rdquo;</p> <p style="text-align: justify;">We asked Kirk what particular item was most popular, &ldquo; I would have to say the SowMAX dispensers.&nbsp; All producers are facing high feed costs and feed saving equipment is important to them.&nbsp; A customer, with sow farms in the Ukraine and Poland, has installed over 1,000 SowMAX units and is sold on the feed savings.&rdquo;</p> <p style="text-align: justify;">He continued, &ldquo;Another big item of interest is concrete slats.&nbsp; We had many producers who see them for the first time and immediately comment on the quality.&nbsp; I think people tend to view concrete slats as all being kind of the same, but we really do build a slat that will last longer.&nbsp; Experienced producers seemed to recognize it very quickly.&rdquo;</p> <p style="text-align: justify;">&ldquo;And&rdquo;, he laughed, &ldquo;they always ask when are we building a slat plant near them&rdquo;</p> <p style="text-align: justify;">Kirk finished up with, &ldquo;The Grower Select line has caught on quickly.

We then weighted the chicks at 7, 14 and 21 days.&nbsp; The chickens in the starter feeder house were routinely 8-12% heavier than feed tray house.&nbsp; We repeated the trial this time, switching the houses between trays and feeders and had almost identical results&hellip;..starter feeders are now part of our routine.</em></p> <p style="text-align: justify;">&nbsp;</p> <p style="text-align: justify;"><strong>Describe how you set up the house with starter feeders?</strong></p> <p style="text-align: justify;"><em>Mike: Each of our houses holds 23,500 birds and we aim to have one supplement feeding station per 75-100 birds.&nbsp; We can place 150 starter feeders between the pan feeders under the feedline. We also like to remove the pan under the control pan and replace it with a large 3&times;3 cardboard tray so the chicks will activate the control pan quicker.&nbsp;&nbsp; We add additional 100 paper trays under the brooders that we feed by hand for 3 days.&nbsp; After that we pick up the paper trays and replace the pan on the end control and all the supplemental feeding is done in starter feeders.</em></p> <p style="text-align: justify;">&nbsp;</p> <p style="text-align: justify;"><strong>Any ideas why the chickens were heavier in the building using starter feeders?</strong></p> <p style="text-align: justify;"><em>Mike:&nbsp;&nbsp; Yes, it is easier to keep supplemental feed in front of the chicks.&nbsp; Using feed trays requires the grower to manually operate the feed system.&nbsp; They have to run the feed system several times a day to put feed on the trays.&nbsp; This becomes increasing difficult, as the chicks get older and more aggressive and start scattering feed as it drops in the trays in the front of the house. The grower has to shut off the front drops as they fill the trays so feed will be delivered equally to the end of the brooder area. &nbsp;&nbsp;With the starter feeders you simply position the feeders under the feedline and fill them up.&nbsp; Within a couple of days the control pan is regulating feed delivery automatically and distributing it down the entire length on the house.&nbsp;&nbsp; Supplemental feed is always available to the birds.</em></p> <p style="text-align: justify;">&nbsp;</p> <p style="text-align: justify;"><em>Most growers would like to put out supplemental feed for ten days but with feed trays this can be a challenge.&nbsp; Since the system is manual it&rsquo;s a little bit of a guessing game to know how much feed to run out.&nbsp; The chicks lie in the trays, scatter and defecate in the feed. &nbsp;&nbsp;&nbsp;A real aggressive flock will waste so much feed growers will stop supplement feeding after eight days.</em></p> <p style="text-align: justify;">&nbsp;</p> <p style="text-align: justify;"><em>With starter feeders the birds can&rsquo;t lay in the feed, they aren&rsquo;t scratching feed into the litter and feed is always available.&nbsp; We can easily keep supplemental feed in front of the chickens for 15-16 days with very minimal wastage.</em></p> <p style="text-align: justify;">&nbsp;</p> <p style="text-align: justify;"><em>That early feed intake is critical.&nbsp; The faster we can get their allotment of starter rations into the birds the heavier those chickens will be at settlement.</em></p> <p style="text-align: justify;">&nbsp;</p> <p style="text-align: justify;"><strong>We understand not everyone is proponent of starter feeders?</strong></p> <p style="text-align: justify;"><em>Mike: Yes that&rsquo;s true.&nbsp; Some people will argue feed trays provide more eating space.&nbsp; Consider this, when there are 100 birds lying in a feed tray, access is very limited.&nbsp;&nbsp; We think their access to feed is increased vs. trays because birds are not covering up the feed.</em></p> <p style="text-align: justify;">&nbsp;</p> <p style="text-align: justify;"><strong>Do you clean the feeders between flocks?</strong></p> <p style="text-align: justify;"><em>Mike: No, because the birds can&rsquo;t mess up a starter feeder like they do a plastic feed tray.&nbsp; We save quite a bit of labor not having to clean the feeders like we would if we used plastic trays.</em></p> <p style="text-align: justify;">&nbsp;</p> <p style="text-align: justify;"><strong>Georgia Poultry is now offering an even better price on starter feeders than ever before.&nbsp; Go to&nbsp;<a href="http://hogslat.com/hi-grow-pre-starter-chick-feeder" target="_blank">www.hogslat.com/hi-grow-pre-starter-chick-feeder</a></strong><strong>.&nbsp; Run a trial on your own farm.&nbsp;&nbsp; Start birds faster and gain a&nbsp;competitive advantage at settlement.</strong></p>urn:store:1:blog:post:44https://hogslat.com/factors-impacting-feed-conversion-2Factors Impacting Feed Conversion<p style="text-align: justify;">Here&rsquo;s a thought provoking list of 20 factors that effect feed conversion in swine production.

Revolver and Boot Hill are formulation with the same active ingredient, Bromadiolone.&nbsp; Revolver is the soft bait version and Boot Hill comes in either a mini block or pellet place pack.</p> <p style="text-align: justify;">&nbsp;</p> <p><img class="size-medium wp-image-693 aligncenter" src="/images/uploaded/wp-content/uploads/2013/03/New-Bait-Rotation_edited-1-300x184.jpg" alt="New Bait Rotation_edited-1" width="300" height="184" style="display: block; margin-left: auto; margin-right: auto;" /></p> <p style="text-align: justify;">&nbsp;</p> <p style="text-align: justify;">&nbsp;</p> <p style="text-align: justify;">&nbsp;</p> <p style="text-align: justify;"><b>Now producers can add another element, texture into their bait rotations.</b>&nbsp; Note the double orange arrows in the rotation diagram illustrating the possible choices.&nbsp; For example if the first bait used was FastDraw the next choice in the rotation could be either Revolver (soft bait) or Boot Hill (mini blocks) as they both contain a differen active ingredient Bromadiolone.&nbsp; If Boot Hill was selected the next step in the rotation back to Difethlalone could be either FastDraw (soft bait) or Hombre (mini blocks).</p> <p style="text-align: justify;">&nbsp;</p> <p style="text-align: justify;">Also note on the diagram the rodenticide Gunslinger highlighted with the blue circle.&nbsp; We highly recommend Gunslinger be inserted into any bait rotation at clean out as it most effective when animals aren&rsquo;t present and feed sources can be removed.

While this set-up allowed for greater flexibility in feeding, the front bin of the pair was often prone to plugging.</p> <p style="text-align: justify;">If we look at the anchor bearing that is present in the rear bin, one&nbsp;would notice that it has a restrictor tube over the shaft.&nbsp; This restrictor tube fills the core of a&nbsp;flexible auger and prevents feed from filling the core and overloading an auger.&nbsp;This restrictor is not present in the front bin.&nbsp; When the slide is opened feed overloads the system faster than the auger will move it away.&nbsp; The obvious solution is to cut the opening down by closing off the slide to restrict feed flow.&nbsp; This can cause other problems as a feed flows tends to flow only down one side of the bin.&nbsp; A better solution is to use baffles in the boot to restrict feed flow.&nbsp; This works to prevent plugging but can cause feed bridging in the bin.</p> <p style="text-align: justify;">&nbsp;</p> <p><img class=" size-medium wp-image-696 alignleft" src="/images/uploaded/wp-content/uploads/2013/04/feed-bin-auger-drawing-anchor-bearing-300x224.jpg" alt="feed-bin-auger-drawing-anchor-bearing" width="300" height="224" style="display: block;

We knew we could lower the cost if we reduced the number of people that handled a product, and in many cases improve the quality.</p> <p style="text-align: justify;">Replacement motors for fans and feed systems were the first items we started to direct source.  OEM Fan and feed auger companies do not produce their own motors; they all buy from the same motor companies.</p> <p style="text-align: justify;">We did not just buy off-the-shelf motors. We specified certain improvements in the motors based on our experience.  For instance, one problem according to our service department was motor shaft breakage.  We changed the shaft diameter blend radius and specified a hardened shaft of 1144 steel. We eliminated the problem.</p> <p style="text-align: justify;"><strong><em>Some people may have the perception that GrowerSELECT products are just cheap generic copies. How would you answer that?</em></strong></p> <p style="text-align: justify;">I am not going to tell anybody that we invented feed systems or fans. However, in almost every case we are able to look at existing products and make improvements.</p> <p style="text-align: justify;">We evaluate every item developed for the GrowerSELECT lineup in three different ways.</p> <p style="text-align: justify;"><span>First, from an engineering standpoint.</span></p> <p style="text-align: justify;">Can we make this product out of different material? Can we make it easier to manufacture?  Can we change the shape or size to eliminate problems?</p> <p style="text-align: justify;"><span>Second, we evaluate from a repair standpoint with feedback from our service departments.</span></p> <p style="text-align: justify;">What are you fixing out in the field?  Where is this product failing?  What would make the product easier to service?</p> <p style="text-align: justify;"><span>Third, and most importantly, we evaluate from our customer’s standpoint.</span></p> <p style="text-align: justify;">Is this the right product? Is this the right size?  What is giving you the biggest headache in using this product?   What changes would you make?</p> <p style="text-align: justify;">After gathering this information, we conduct the <strong>Process Failure Effect Mode Analysis or PFEMA</strong>.  Simply put, this is a logic method for determining why a product fails and how to correct it.  We document the process and can refer back to it when problems arise.</p> <p style="text-align: justify;">We then create detailed 3D computer models of the proposed product and subject it to computer-simulated stress tests.</p> <p style="text-align: justify;"><strong><em>Wait a minute; you can test the product before it is even built?</em></strong></p> <p><img class="alignleft size-medium wp-image-882" src="/images/uploaded/wp-content/uploads/2014/08/SowMAX-feed-hopper-blog-300x225.jpg" alt="SowMAX feed hopper blog" width="300" height="225" style="float: left; padding: 10px;" /></p> <p style="text-align: justify;">Yes, here’s a good example.  When we first designed the blue plastic hopper for the <a href="http://www.hogslat.com/sowmax-hopper">SowMAX</a>, we did not have a lip at the top.  When tested via computer simulation, we realized it might crack when impacted, for example if a feed cart banged into it.  We added the lip to strengthen the hopper and eliminated a potential problem.</p> <p><img class="alignleft wp-image-883" src="/images/uploaded/wp-content/uploads/2014/08/ITM-HS524-IMG-300x231.jpg" alt="Grower Select clear upper boot" width="180" height="139" style="float: right; padding: 10px;" />Another example is the<a href="http://www.hogslat.com/grower-select-30-clear-plastic-boot"> GrowerSELECT® clear upper boot</a>, injected from impact-resistant polycarbonate.  It does not have to be as thick as plastic boots used by other manufacturers to have a superior breaking strength.  We were able to “tweak” the material thickness and avoid adding unnecessary additional cost to the end user.</p> <p style="text-align: justify;">The next part of the process is to send the drawings to a manufacturer and order sample parts to test against a quality control process known as <strong>PPAP or Production Part Approval Process</strong>.</p> <p style="text-align: justify;"><em><strong>Okay, what does that mean?</strong></em></p> <p style="text-align: justify;">It is the same quality control process the automobile supply industry uses.  It means we take the sample products and measure them against the drawings we created.  We particularly identify those measurements most critical to the quality of the product.</p> <p style="text-align: justify;">Once we are satisfied that the sample batch is correct, we then order a small production run.  This first-production run is then field tested.  Our service group installs them on farms, and we monitor the results.</p> <p style="text-align: justify;">After field-testing is completed, we release the product to manufacturing.</p> <p><img class="alignleft size-medium wp-image-884" src="/images/uploaded/wp-content/uploads/2014/08/Classic-Flood-QC-check-300x168.jpg" alt="Classic Flood QC check" width="300" height="168" style="float: left; padding: 10px;" />Before receiving those released products into warehousing, our Quality Control department conducts a series of QC checks.  Keith Riley, QC department head, creates an <strong>Incoming Inspection Document</strong> for each item.  This establishes a benchmark of quality checks used to test production parts.  This is not only done the first time we receive the product, but every time that product arrives from the manufacturer. </p> <p style="text-align: justify;"><strong><em>How many people work in Hog Slat’s engineering department?</em></strong></p> <p><img class="alignleft size-medium wp-image-885" src="/images/uploaded/wp-content/uploads/2014/08/Tim-Timblog-300x200.jpg" alt="Tim &amp; Tim,blog" width="300" height="200" style="float: right; padding: 10px;" /></p> <p style="text-align: justify;">We have nine engineers and six Quality Control members. We have a good core of experienced engineers with several younger guys that we have hired…I like to say we have just the right blend of “gray hair” in the group. I have to say the younger guys have a great “toolbox” they bring with them. They are contributing with new technology.  A good example is the <a href="http://www.hogslat.com/3d-printer-shapes-livestock-and-poultry-equipment/">3D printer</a> we recently added to the department.  It is allowing us to perform some things we had not been able to do before.</p> <p style="text-align: justify;"><strong><em>What are future goals for your group?</em></strong></p> <p style="text-align: justify;">Continuous improvement of products.  <strong>Just because we have a product developed doesn’t mean we quit trying to make it better. </strong> We think we can improve motors. One of the principle reasons we are able to offer a two-year warranty is that we have such a very small percentage of motors returned under that warranty. But, we have some ideas that will improve these motors even more.</p> <p><img class="alignleft size-medium wp-image-892" src="/images/uploaded/wp-content/uploads/2014/08/SupplyChain-300x300.jpg" alt="Hog Slat Supply Chain" width="300" height="300" style="float: left; padding: 10px;" />Hog Slat has a very unique position in the industry.  We are responsible directly to the end user.  It is our own people installing and servicing the products we sell.  We cannot pass off problems to someone in the supply chain; we are the entire supply chain to the end user.</p> <p style="text-align: justify;">We have access to company farms to test new products.  We have feedback from our own service crews.  Our goal is to use these resources to improve product offerings and get those improvements to the market faster.</p> <p style="text-align: justify;"><b></b>One of things I think we are the best at is <strong>identifying the optimum place in the world to manufacture a product.</strong>  We are not just throwing everything to Southeast Asia.  In fact, we have moved several products back to the United States. A good example is Classic Flood feeders, we started overseas but now these parts are molded in the U.S.</p> <p style="text-align: justify;"><b></b>We do a lot of final assembly at our locations in Clinton, NC and Humboldt, IA.  We source items from the U.S. and other parts of the globe, bring those components in to test, then assemble the end products.  Using this process we have more control over the quality of the final product.</p>urn:store:1:blog:post:61https://hogslat.com/weatherflow-wind-meter-for-your-smartphoneWeatherFlow - Wind Meter for Your Smartphone<p style="text-align: justify;"><img class="alignleft size-medium wp-image-901" src="/images/uploaded/wp-content/uploads/2014/08/ITM-WeatherFLow-in-package-IMG_edited-1-280x300.jpg" alt="ITM-WeatherFLow in package-IMG" width="280" height="300" />&nbsp;</p> <p style="text-align: justify;">The old saying, &ldquo;

After placing a lag bolt in the wall about ½” short of flush, you simply hang the machine from a single keyhole slot in the back of the cabinet. It is much easier to level and add the four mounting lag bolts because the unit remains supported. </p> <p><img class="alignleft wp-image-1001" src="/images/uploaded/wp-content/uploads/2014/09/Curtain-machine-top-300x256.jpg" alt="Curtain machine top" width="210" height="179" style="float: right; padding: 10px;" /></p> <p style="text-align: justify;">The Curtain Machine includes three sealed ball bearing head pulleys instead of two.  The extra pulley is added to increase the choices for installing the main cables.  Use the two outside pulleys to cable the machine on both sides of the building.  Single-sided installations have the off side cable routed through the top pulley.</p> <p><img class="alignleft wp-image-1002" src="/images/uploaded/wp-content/uploads/2014/09/Curtain-machine-drive-block-300x200.jpg" alt="Curtain machine drive block" width="240" height="160" style="float: left; padding: 10px;" /></p> <p style="text-align: justify;">One of the highest mortality items on a screw type machine is the load block.  Other curtain machines use bronze, brass or nylon. However, the GrowerSELECT machine utilizes a self-lubricating, low friction acetal plastic for both the insert nut and load block slides.   For a more in-depth comparison see our blog post, <a href="http://www.hogslat.com/more-than-you-ever-wanted-to-know-about-curtain-machine-load-blocks/">“More Than You Ever Wanted to Know about Curtain Machine Load Blocks.”</a></p> <p><img class="alignleft wp-image-1003" src="/images/uploaded/wp-content/uploads/2014/09/Curtain-machine-Aux-switch-300x244.jpg" alt="Curtain machine Aux switch" width="240" height="195" style="float: right; padding: 10px;" /></p> <p style="text-align: justify;">The Curtain Machine features dual limit switches.  The primary limit switches set the travel length, with secondary or redundant switches backing these up. If the first switch fails and engages the secondary switch, the machine shuts down and must be serviced before operating again.  Also included is an auxiliary switch, used to activate a fan after the curtain closes.  Other brands charge extra for this feature.</p> <p><img class="alignleft wp-image-1004" src="/images/uploaded/wp-content/uploads/2014/09/Curtain-machine-switches-300x200.jpg" alt="Curtain machine switches" width="240" height="160" style="float: left; padding: 10px;" /></p> <p style="text-align: justify;">Another feature you will appreciate is the local control switches, standard with the GrowerSELECT Curtain Machine.   A toggle switch sets the machine in manual and overrides the ventilation control.  This is a great safety feature that prevents anyone from activating the unit while it is being serviced.  In addition, it certainly makes it easier to set the limit switches compared to performing this task from a remote controller.</p> <p><img class="alignleft size-medium wp-image-1007" src="/images/uploaded/wp-content/uploads/2014/09/GS-Curtain-machine-close-up-mounted_edited-1-125x300.jpg" alt="GS Curtain machine close up mounted_edited-1" width="125" height="300" style="float: right; padding: 10px;" /></p> <p style="text-align: justify;">Eventually, any curtain machine will have to be serviced, and this is where the GrowerSELECT Curtain Machine shines.  Note the cutouts in the galvanized housing. You can slip the entire motor assembly out of these slots after loosening three mounting bolts.  It is much easier to service the motor outside of the cabinet.</p> <p style="text-align: justify;">The entire screw assembly will also come out through these cabinet slots.  It’s still a big job, but it’s possible to slide the entire assembly out for servicing rather than dismantling the screw inside the cabinet.</p> <p style="text-align: justify;">Although not groundbreaking, the GrowerSELECT Curtain Machine is an example of Hog Slat’s commitment to engineering better products.  Click on <a href="http://www.hogslat.com/grower-select-curtain-machine" target="_blank">Curtain Machine</a> for pricing and ordering information.</p>urn:store:1:blog:post:64https://hogslat.com/clear-advantage-for-clear-feed-trayClear Advantage for Clear Feed Tray<p style="text-align: justify;">Hog Slat/ Georgia Poultry stores just received their first shipments of a new type of feed tray.&nbsp; Manufactured from post-consumer waste, the&nbsp;<strong>Pur-Chick Clear Feeder Tray</strong>&nbsp;is different than the paper or plastic trays currently in use.</p> <p><img class="alignleft size-medium wp-image-993" src="/images/uploaded/wp-content/uploads/2014/09/itm-521102-clr-img-300x300.jpg" alt="itm-521102-clr-img" width="300" height="300" style="display: block; margin-left: auto; margin-right: auto;" /></p> <p style="text-align: justify;">They are crystal clear, lightweight, disposable and appear to have some advantages over red plastic and paper trays.</p> <p style="text-align: justify;">There seems to be less Darkling beetle activity in the clear trays.&nbsp; I asked several industry &ldquo;bug experts&rdquo;, and they weren&rsquo;t sure why.</p> <p style="text-align: justify;"><em>&ldquo;Maybe it&rsquo;s because they can&rsquo;t hide under the clear tray.&rdquo;</em></p> <p style="text-align: justify;"><em>&ldquo;The sides might be too slick for the beetles to climb.&rdquo;</em></p> <p style="text-align: justify;"><em>&ldquo;They can&rsquo;t eat through the plastic as easy as the paper tray.&rdquo;</em></p> <p style="text-align: justify;">Watch the first part of the video and see for yourself.</p> <p style="text-align: justify;">Chicks seem to be attracted to the clear trays over paper or red plastic.&nbsp; Again, not sure exactly why.</p> <p style="text-align: justify;"><em>&nbsp;&ldquo;They can see the feed better because the trays are clear.&rdquo;</em></p> <p style="text-align: justify;"><em>&ldquo;The reflective surface might look like water.&rdquo;</em></p> <p style="text-align: justify;"><em>&ldquo;When they walk on the tray, it makes a crinkling sound which they are familiar with from the hatchery.&rdquo;</em></p> <p style="text-align: justify;">Maybe.

As the load block moves up and down the Acme screw, the friction generated causes the insert to fail.  If friction is reduced, wear and maintenance of the insert is reduced.</p> <div id="attachment_1171" class="wp-caption alignleft"><img class="size-medium wp-image-1171 " src="/images/uploaded/wp-content/uploads/2014/09/GS-Load-Block-Compare-300x129.jpg" alt="Curtain Machine loads block compared" width="300" height="129" style="display: block; margin-left: auto; margin-right: auto;" /> <p class="wp-caption-text" style="text-align: center;">1.

Keep a bearing greased, and it will last a long time. What is interesting though is the rating for an acetal load nut without grease is the same as any of other insert materials with grease.</p> <p style="text-align: justify;">As a matter of fact, the acetal load nut does not even have a grease zerk.  However, we still recommend greasing the Acme shaft with general purpose Lithium grease, primarily to prevent surface rust on the shaft.</p> <p style="text-align: justify;">I wish you could put your hands on the four inserts in the picture.  The acetal has a slippery, almost oily feel to it; different than the nylon insert.  It is a denser, heavier plastic that is less brittle compared to nylon.</p> <p style="text-align: justify;">The real advantage is in the day-to-day maintenance on your farm.  The best intentions (like greasing a curtain machine) get lost in the bustle of all the work.  Why not choose a curtain machine with features that reduce maintenance?   Click on <a href="http://www.hogslat.com/grower-select-curtain-machine">Curtain Machine</a> for more information.</p>urn:store:1:blog:post:66https://hogslat.com/pen-vise-is-the-right-tool-for-cleaning-brooder-orificesPen Vise is the Right Tool for Cleaning Brooder Orifices<p style="text-align: justify;">Having the right tool makes any maintenance chore easier and Hog Slat&rsquo;s Pen Vise is the perfect tool for cleaning clogged brooder and heater orifices.</p> <p><a href="/images/uploaded/wp-content/uploads/2014/09/Pen-Vise.jpg"><img class="alignleft size-medium wp-image-1159" src="/images/uploaded/wp-content/uploads/2014/09/Pen-Vise-300x229.jpg" alt="Pen Vise" width="300" height="229" style="display: block; margin-left: auto; margin-right: auto;" /></a></p> <p style="text-align: justify;">Instead of &nbsp;looking for a piece of wire or a drill bit close to the right size, the Pen Vise keeps tapered cleaning needles at your fingertips.&nbsp; This tool features a screw-tightened jaw on one end with a 12-needle storage compartment on the opposite.

Since then, Jeff and his family along with the help of quality employees have grown their breed to wean operation to 4,000 sows housed in 2 locations.  We spoke with owner, Jeff Lueke:</p> <p><img class="alignleft size-medium wp-image-1175" src="/images/uploaded/wp-content/uploads/2014/09/074-168x300.jpg" alt="074" width="168" height="300" style="float: left; padding: 10px;" /><strong>Jeff, you have purchased several Grow-Disk™ systems, why did you decide to install this feeding system?</strong></p> <p style="text-align: justify;">I really felt like we were gaining efficiencies in the farrowing department. We saw how it could provide advantages to our employees, allowing them to be more efficient and manage more sows. Within our operation we also set target goals. These goals consisted of narrowing down the wean to first service interval, drive a heavier pig out the door at weaning, and increase lactation length leading to subsequent larger litter sizes for pigs. In our management plan, we felt that these two products, SowMAX and Grow-Disk, would be a big help to reach our target goals by getting more feed to the sows.</p> <p style="text-align: justify;"><b>How many Grow-Disk™ systems have you installed?</b></p> <p style="text-align: justify;">3. All have been installed into our farrowing barns, but I would not hesitate to install them into any application.</p> <p style="text-align: justify;"><b>How do you use Grow-Disk™ to feed the sows?</b></p> <p style="text-align: justify;">We combine the Grow-Disk with the SowMAX. We feel that the combination of these products delivers a very good program. We basically want the sows to have access to full feed. Between these two products we feel that we can deliver that to our sows very efficiently. The system still gives us flexibility to limit feed intake because we include the Sow Drop. The Sow Drop allows us to limit feed intake if we want to, whether it is in early lactation, pre-farrowing, or for the first three days post-farrowing. In post-farrowing we schedule to feed five times throughout the day, in pre-farrowing we schedule to feed twice a day.</p> <p style="text-align: justify;"><strong>How have the Grow-Disk™ systems performed for you? What benefits have you seen?</strong></p> <p style="text-align: justify;">I have no complaints; I do believe that we are getting more daily feed intake from our sows with the system. The system is hands-off, requiring less labor to feed. With this automatic feeding we are able to keep feed available, and produce less wastage.</p> <p style="text-align: justify;"><b>Why did you choose Grow-Disk™ instead of a flexible auger system for your project?</b></p> <p style="text-align: justify;">My local sales contact, Carl Herrmann, shared with me some of the advantages that Grow-Disk can offer. Knowing that it was a new product, and knowing that I’ve had success with Hog Slat products in the past, it made me anxious to try it. I think its heavy duty, reliable, and I have not been disappointed.</p> <p style="text-align: justify;"><b>Switching gears, tell us about your routine feeding with SowMAX.</b></p> <p style="text-align: justify;">The system that we set up is basically designed to keep feed available for the sow to access at all times, but not have so much feed supply that if there was a malfunction we would have a pit full of feed. The system allows us to make that work. At most any time there’s 12-20 lbs. of feed available to the sow. If that particular sow wants to get up at 6 a.m. and eat 15 pounds of feed, it’s there. If a sow wants to eat five small meals throughout the day she has the opportunity to do that as well. I think that we forget that hogs are somewhat individuals like people, and may all have a little different idea of how they want to eat. In the past when we fed with a scoop and cart, the sows got trained to jump up and eat whenever it was time to feed. Even if a litter of piglets just started nursing, the sow still jumped up to eat. The sows are much more content and apt to eat at their convenience than they are when you decide when it’s time to feed.  For daily management of the SowMAX, we clean and make necessary adjustments to the feeders twice a day. We have been able to keep SowMAX feeders cleaner compared to other systems. The feeders are simple and easy to utilize and maintain.</p> <p style="text-align: justify;"><b>What advantages have you noticed with SowMAX over how you fed sows in the past?</b></p> <p style="text-align: justify;">We have been able to accomplish our management goals by incorporating SowMAX into our operation. I do believe we have raised heavier pigs. We have noticed that SowMAX wastes less feed and requires less maintenance compared to a solid tube. Having the ability to keep fresh feed in front of the sow all day has been a great benefit.</p> <p style="text-align: justify;"><b>Do you use any other Hog Slat equipment?</b></p> <p style="text-align: justify;">We incorporate Hog Slat’s concrete slats, penning, boar carts, Sow Drops, farrowing crates, and Tridek flooring, among others into our operation.  I’ve found this equipment to meet my standards for over 20 years.</p> <p style="text-align: justify;"><b>Do you have any suggestions for other hog farmers looking into the GrowerSELECT® product line?</b></p> <p style="text-align: justify;">It’s a viable program that should be looked at. I think it is cost efficient for the performance. It would be an asset to any building project. </p>urn:store:1:blog:post:54https://hogslat.com/poultry-lighting-advantages-of-led-bulbsPoultry Lighting- Advantages of LED Bulbs<p>1. Incandescent bulbs are being phased out by numerous countries (US included) making it now illegal to manufacture many incandescent bulbs leaving only those bulbs still in supply to sell. Usually the higher the wattage the more expensive and more difficult the bulb is to find now with the new laws in effect. LED bulbs do not face this issue and benefit from&nbsp;newer technology that is developing&nbsp;each year.</p> <p>2. Incandescent bulbs are not efficient at all in terms of converting energy for just light production. Most of the energy is released as heat and not as light thus making them very inefficient. In contrast, LED bulbs convert nearly all their energy to light production and are very efficient. For example a 40 watt incandescent produces roughly 400 Lumens which is a little less than the average 8 watt LED bulb that produces about 450 Lumens. This fact alone makes it easy to see how LED bulbs can pay you back in energy savings over time, by giving you the same Lumens (light output) for much less electrical usage.</p> <p>3. Incandescent bulbs have a typical lifespan of about 2,000 hours or less, CFL and Cold Cathode bulbs around 10,000 hours, and LED&rsquo;s can have a lifespan over 25,000 hours. This means less time and labor required to change bulbs by switching to LED bulbs.</p> <p>4. LED bulbs don&rsquo;t lose their intensity like Cold Cathode does. Some research shows that after time Cold Cathode bulbs lose light intensity the older they get.</p> <p>5. Our LED bulbs are fully dimmable and can be dimmed as low as 1%. They do not have issues like CFL bulbs do when dimming at lower levels and work on nearly all dimmers.</p> <p>6. LED bulb warranties are longer. Most agricultural rated LED&rsquo;s have a minimum of a 3 year warranty and some go as high as 5. Incandescent bulbs do not have a warranty and CFL and Cold Cathode bulbs usually only have a 1 year warranty.</p> <p>7. Not all LED bulbs are alike. Do not confuse Agricultural rated LED bulbs and residential LED bulbs. They are not the same, and do not dim the same and thus do not perform the same. They may be more attractive due to their lower price, but they will not hold up in your poultry house like the agricultural&nbsp;rated LED&rsquo;s will.</p> <p>8. Some electrical companies, co-ops, and federal grants offer rebates or cost share programs that may be available in your area. Contact your local USDA Rural Development office to inquire about the REAP program or ask your electricity supplier for any rebates they may offer</p> <p>9. By changing out incandescent bulbs to LED bulbs some have shown a payback as quickly as a few flocks, and if you are changing from CFL or Cold Cathode bulbs the payback can be around 1 to 2 years depending on your lighting program and setup. Regardless, know that by changing to LED you are cutting your energy usage, putting money back in your pocket, having a more durable and longer lasting bulb, and a bulb with a better warranty.&nbsp;<a href="http://www.hogslat.com/energy-saving-led-light-bulbs" target="_blank">Take the next&nbsp;step and invest in LED bulbs today</a>!</p>urn:store:1:blog:post:56https://hogslat.com/history-of-sow-housingHistory of Sow Housing<p>I was scrolling the web for information on sow housing and ran across this piece authored by John J.

One commonly overlooked item is the feed delivery system. Whether you choose to have the auger inspected by a service crew or do the work yourself, the following is a checklist of essential feed system maintenance items for producers to consider.</p> <p><strong>Remove the Feed</strong><br />The most important and basic procedure for auger maintenance is to empty all the feed from the system. Feed left in the auger tube will draw moisture and cause the auger flighting to rust.</p> <p><strong>Upper and Lower Boots</strong><br />The metal lower boots should be visually inspected for worn or rusted areas, bent slide gates and damaged access covers. GrowerSELECT&reg; components can be used to replace individual items including body weldments for all flexible auger sizes. Go to&nbsp;<a title="Hog Slat boot repair parts" href="http://www.hogslat.com/boots-and-unloaders-2" target="_blank">GrowerSELECT Unloader Components</a>.</p> <p>Grower Select clear upper boots can replace existing solid boots so potential problems with feed delivery are easier to spot. &nbsp;Injected from impact-resistant transparent polycarbonate, GrowerSELECT boots will fit any 16&rdquo; bin opening and are available in 30&deg; or straight models. Go to&nbsp;<a title="grower Select clear boot" href="http://www.hogslat.com/grower-select-strainght-clear-plastic-boot">GrowerSELECT Clear Boots</a></p> <p><strong>Anchor Bearings</strong><br />Auger bearings are a high wear item and should be checked whenever they are squealing or rattling. To inspect the anchor bearing, loosen the U-bolts holding the bearing, pull the bearing out from the tube and clamp a vise grip on the auger to hold it in place. Inspect the anchor bearing for visible wear and excess play. If the bearing needs to be replaced, select a GrowerSELECT anchor bearing that matches the size and brand of your system.&nbsp;Go to&nbsp;<a title="Hog Slat Anchor Bearings" href="http://www.hogslat.com/boots-and-unloaders-2">GrowerSELECT Anchor Bearings</a></p> <p><strong>Flexible Auger</strong><br />Auger that is more than ten years old or installed with multiple turns should be examined for wear. Examine the auger to look for sharp edges concentrating on the elbow areas. Also check the distance between the flighting making sure this distance has not been compacted or stretched. To remove the auger for inspection; detach the anchor bearing from the auger and allow the auger to retract inside the tube. Go up to the drive unit and open the inspection plate on the control unit. Loosen the hex head bolt on the clamp holding the auger to the tube anchor. Holding the auger solid, rotate the anchor counterclockwise until the auger is free. Go back to the boot area and pull the auger out the back end of the system.</p> <p>There are several options for repair.<br />A) Replace the entire auger.<br />B) Cut out and replace only the worn section.<br />C) Turn the auger end for end and replace. This will place the worn section of auger in a straight section of the tube instead of in an elbow section.</p> <p><span>Grow-Flex&trade; auger is available custom lengths that are cut to order.&nbsp;</span><a href="http://www.hogslat.com/auger-and-drops-2" target="_blank">Go to Grow-Flex&trade; Auger</a></p> <p><strong>Elbows</strong><br />Many (most?) 10-year auger systems have duct tape over small holes in the tube where the auger enters the barn. Now is the time to replace the high wearing elbow sections while the auger is removed from the system.</p> <p><strong>Gear Head Oil</strong><br />The oil in auger gear heads should be completely replaced every two years. Remove the bottom and side plugs allowing the oil to drain out of the gear head. Replace the bottom plug and refill with oil until it reaches the level of the side plug. Replace side oil plug. GrowerSELECT&nbsp;Gear Oil is specialty 80W-90 oil designed for use in any existing auger gear head.&nbsp;<a title="Grower Select Auger Head Gear Oil" href="http://www.hogslat.com/grower-select-15-oz-gear-oil" target="_blank">Purchase GrowerSELECT Gear Oil here</a>.</p> <p><strong>Pinion Gears<br /></strong>It is also a good time for a visual inspection of the pinion gear connecting the motor shaft to the gear head. The teeth of the pinion should be sharply cut; pinions with rounded teeth should be replaced. There is a GrowerSELECT replacement pinion gear for most existing auger systems&hellip;.Go to&nbsp;<a title="Grower Select Pinion Gears" href="http://www.hogslat.com/drive-units-2" target="_blank">GrowerSELECT Pinion Gears</a></p> <p><strong>Feed Level Controls</strong><br />Faulty feed controls can cause feed outages or wastage when they malfunction. There are many options of GrowerSELECT feed level controls available for replacements. The&nbsp;<a title="Grower Select feed level control" href="http://www.hogslat.com/grower-select-drop-tube-control-switch">HS529</a>&nbsp;is a direct replacement for feed level controls mounted in the feeders. The&nbsp;<a title="Grower Select Proxy Plus sensor" href="http://www.hogslat.com/grower-select-proxy-plus-feed-sensor" target="_blank">Proxy Plus (HS10)</a>&nbsp;and the&nbsp;<a title="Grower Select Proxy HS09" href="http://www.hogslat.com/grower-select-proxy-classic-feed-sensor" target="_blank">Proxy Classic (HS09)</a>&nbsp;are&nbsp;GrowerSELECT replacements for existing proximity switches.<br />This may also be a great time to consider a complete change in feed control switches. The&nbsp;<a title="Grower Select Drop Tube Control Switch" href="http://www.hogslat.com/grower-select-drop-tube-control-switch" target="_blank">Grower Select Drop Tube Control Switch (HSDTC01)</a>&nbsp;is an excellent option for controlling the feed system. This type of switch removes the electrical components from inside the feeders helping minimize switch failure due to electrical problems.</p> <p><strong>Feed Bins</strong><br />Older feed bins may have rusted areas or even pinholes in the exterior metal sheets. An excellent product to restore these areas and extend the bin&rsquo;s useful life is&nbsp;<a href="http://www.hogslat.com/vanberg-coatings-amc100l-urethane-coating" target="_blank">AMC100L</a>; an aluminum based coating that provides corrosion and weather protection. It is available in DIY kit form containing 1 quart of AMC100L, 1 pint&nbsp;of rust remover and 4 pieces of seam tape. This starter kit will cover 200-300 sq ft.&nbsp;<a href="http://www.hogslat.com/vanberg-coatings-amc100l-metal-repair-kit" target="_blank">Purchase the&nbsp;AMC100L-K kit here</a>.</p> <p>Producers have also upgraded feed bins with a simple feed level indicator called the Bin Flag. This low-cost device (just over $100) allows operators to check bin feed levels without climbing. No wiring is required for operation and the installation is all done from the outside. The Bin Flag can also be connected to building alarm system for dialer notification of feed outages.&nbsp;<a title="Bin Flag " href="http://www.hogslat.com/bin-flag-feed-level-indicator" target="_blank">Go to Bin Flag.</a></p> <p>Contact a local Hog Slat store&nbsp;<a title="Hog Slat Store Locator" href="http://www.hogslat.com/t/SalesAndStoreLocator" target="_blank">(see store listings)</a>&nbsp;or go to&nbsp;<a href="http://www.hogslat.com/feeding-systems-components">http://www.hogslat.com/feeding-systems-components</a>to order feed system repair items.

Stainless steel legs rotate to allow placement of an anchor in a slat opening.  A set bolt is tightened to secure the leg to the stall side.  Three top and four front bars attached to the stall sides with clamps, making it easier to get a straight installation without drilling or welding.</p> <p style="text-align: justify;"><img class="alignleft size-full wp-image-1477" src="/images/uploaded/wp-content/uploads/2014/11/Euro-Breeding-Stall-3.jpg" alt="Euro Breeding Stall 3" width="449" height="299" /></p> <p style="text-align: justify;">The stainless steel feed trough will outlast composite or concrete troughs.   Because sows can lie with their heads under the raised trough, the overall length can be reduced to 1.8 meters and still meet EU regulations requiring a stall to be 2 meters long.</p> <h3 style="text-align: justify;">International Crate</h3> <p style="text-align: justify;"><img class="aligncenter size-full wp-image-1478" src="/images/uploaded/wp-content/uploads/2014/11/International-crate-front.jpg" alt="International crate front" width="700" height="467" /></p> <p style="text-align: justify;">A typical pen layout will have farrowing stalls facing out against the room walls with only a center alleyway.</p> <p style="text-align: justify;">The combination feed and water trough is raised to allow the sow more effective stall length.  Many producers choose to install the SowMAX (<a href="http://www.hogslat.com/sowmax-feed-dispenser">read more…..</a>) and fill with an automatic auger or chain disk system as hand feeding is difficult without a front feeding alley.</p> <p style="text-align: justify;"><img class="aligncenter size-full wp-image-1479" src="/images/uploaded/wp-content/uploads/2014/11/International-Crate-back.jpg" alt="International Crate back" width="700" height="153" /></p> <p style="text-align: justify;">To load the crates the rear creep panel is opened, the rear gate unfastened and the movable side panel is slid to its open position. After the sow moves into stall, the operator adjusts the movable side to the size of the sow and selects one of the holes in the rear gate to hold it in place.  The operator then adjusts the bottom bow bar for large or small sows.  The bow bars also include anti-crushing bars to reduce pig mortality.</p> <p style="text-align: justify;"><img class="alignleft size-full wp-image-1480" src="/images/uploaded/wp-content/uploads/2014/11/Euro-Farrowing-Floor.jpg" alt="Euro Farrowing Floor" width="200" height="300" /></p> <p style="text-align: justify;">Hog Slat displayed its plastic flooring and with interlocking cast center sections for farrowing.  Optional types of flooring sections, including red heating sections, allow producers to design a custom floor.  Creep areas are larger than typically used in the U.S.   The EuroTier floor measured 1.8 meters (5.9′) wide by 2.4 meters (7.87′) long.</p> <p style="text-align: justify;"><img class="alignleft size-full wp-image-1481" src="/images/uploaded/wp-content/uploads/2014/11/Euro-Penning-2.jpg" alt="Euro Penning 2" width="449" height="299" /></p> <p style="text-align: justify;">Hog Slat also featured traditional style European penning with PVC planking on the bottom and galvanized pipes fastened to formed stainless steel posts.  Notice the plastic fasteners at the end of the pipes, after the pipes are cut to length the plastic ends are forced onto the pipe and bolted into place.  U.S. style horizontal penning is also finding some favor with some European producers as it is more cost effective and allows for better ventilation.</p> <p style="text-align: justify;">Going forward, you will see a constant blend of American and European concepts reflected in the equipment Hog Slat builds for Europe.  Hog Slat’s manufacturing, sourcing and distribution expertise will lower the final cost to the producers without sacrificing quality.</p> <h4 style="text-align: justify;">U.S. concepts in ventilation (tunnel), feeding (SowMAX), and finishing equipment (open horizontal penning) will gain acceptance with European producers looking for maximum efficiencies in producing pork.</h4>urn:store:1:blog:post:78https://hogslat.com/sowmax-testimonial-from-germanySowMAX Testimonial from Germany<p><img class=" wp-image-1399 alignleft" src="/images/uploaded/wp-content/uploads/2014/11/Ulf-SowMAX-300x232.jpg" alt="Ulf &amp; SowMAX" width="240" height="186" style="float: left; padding: 10px;" />In an earlier blog post we reported the interest shown in the SowMax (<a href="http://www.hogslat.com/sowmax-is-a-hit-at-eurotier/">see more….)</a> at this year’s EuroTier.  Shown is German sales rep Ulf  Maroske as he explains features and benefits to a customer at the show.  We later received this email from Ulf concerning a customer who purchased 20 International farrowing crates and 50 SowMAX dispensers to fit on existing crates this October.</p> <p><img class="aligncenter wp-image-1400" src="/images/uploaded/wp-content/uploads/2014/11/International-Crates.jpg" alt="International Crates" width="819" height="614" style="display: block; margin-left: auto; margin-right: auto;" /></p> <p style="text-align: justify;">“When visited my customer last week the piglets were 14 days old.

The Farmstead nest provides hens with sufficient space to lay high-quality eggs, promote optimal hygiene, and above all are user-friendly and durable.</p> <p style="text-align: justify;">Farmstead nests are constructed of rugged galvanized steel that bolts together for strength, versus nests that are pop riveted. All edges are rolled to prevent injury to the birds, and divider partitions have ventilation holes to allow for air circulation around the hens to keep them cooler.</p> <p style="text-align: justify;"><img class="alignleft size-full wp-image-1451" alt="Farmstead Nest" src="/images/uploaded/wp-content/uploads/2014/12/Farmstead-Nest.jpg" width="326" height="210" style="float: left; padding: 10px;" /></p> <blockquote> <p style="text-align: justify;"><i>“We recently built a barn for our chickens and had tried a few different nesting options.

More and more producers are hearing about Official ID products and specifically to this article, how it pertains to swine.</p> <p style="text-align: justify;">There are two main categories when it comes to Official ID for Swine. There are &ldquo;840&rdquo; tags and there is the &ldquo;Swine Premises Tag&rdquo;. Below are the details and common questions for both.</p> <h3 style="text-align: justify;"><strong>840 Tags:</strong></h3> <p style="text-align: justify;"><strong>What is an 840 tag?</strong></p> <p style="text-align: justify;">840 tags are USDA approved tags for&nbsp;<span>official individual animal identification.</span>&nbsp;They will have a unique 15 digit number that always starts with &ldquo;840&rdquo; which is the country code for the United States. A manufacturer has to be approved by the USDA to produce a specific 840 tag.</p> <p style="text-align: justify;"><strong>What is a common use for 840 tags in Swine?</strong></p> <p style="text-align: justify;">Increasingly 840 tags are being required for Swine Shows, State and County Fairs and Auctions. They can also be used for Interstate Commerce.</p> <p style="text-align: justify;"><strong>How do I purchase 840 tags?</strong></p> <p style="text-align: justify;">You must have a registered Premises ID before you can purchase 840 Tags. If you don&rsquo;t have your Premises ID you should start with contacting your State Animal Health Agency. You can find your respective state&rsquo;s contact information at the following link:&nbsp;<a title="US State Animal Health Officials" href="http://www.usaha.org/Portals/6/StateAnimalHealthOfficials.pdf" target="_blank">http://www.usaha.org/Portals/6/StateAnimalHealthOfficials.pdf</a></p> <p style="text-align: justify;"><strong><br />Once you have your Premises ID you can order your 840 tags and tag applicator by Destron Fearing from Hog Slat.&nbsp; (See chart below)</strong></p> <p style="text-align: justify;"><img class=" wp-image-1553 alignleft" src="/images/uploaded/wp-content/uploads/2015/03/840-Ear-Tags-Chart.jpg" alt="840 Ear Tags Chart" width="1197" height="367" /></p> <h3 style="text-align: justify;"><strong>Swine Premises (PIN) tags:</strong></h3> <p style="text-align: justify;"><strong>Why is a Swine Premises tag commonly referred to as a PIN tag?</strong></p> <p style="text-align: justify;">Swine Premises tags are&nbsp;<span>official location identification for cull breeding stock</span>&nbsp;(cull sows and boars). The minimum requirement is for them to be used on cull breeding animals just prior to entering harvest channels from their farm of origin.</p> <p style="text-align: justify;"><strong>What does PIN stand for?</strong></p> <p style="text-align: justify;">Premises Identification Number. It is a unique 7 character alpha-numeric national site identifier.</p> <p style="text-align: justify;"><strong>Can I use them for identifying feeder pigs/weaner pigs for movement and/or show pigs?</strong></p> <p style="text-align: justify;">No, they are for use with animals in the breeding herd only.</p> <p style="text-align: justify;"><strong>Why was January 1<span>st</span>, 2015 important for Swine Premises tags?</strong></p> <p style="text-align: justify;">That was the date that the swine industry and packers/processors agreed on to make PIN tags a requirement of sale. If a producer wants to receive full value for their cull breeding animals from that date forward, the animals need an Official Swine Premises tag in their ear before leaving their farm of origin.<strong><br /></strong></p> <p style="text-align: justify;"><strong>When should I apply the PIN tags to my animals?</strong></p> <p style="text-align: justify;">Most producers are applying them to new breeding animals as they enter the breeding herd and are using it as their management tag. You may also apply them when culling an animal from the farm, just prior to the animal entering harvest channels.</p> <p style="text-align: justify;"><strong>How do I purchase Swine Premises (PIN) tags?</strong></p> <p style="text-align: justify;">You must have a registered Premises ID (National 7 character alpha-numeric ID) before you can purchase Swine Premises Tags. If you don&rsquo;t have your Premises ID you should start with contacting your State Animal Health Agency.

Known as a treadle feeder, the Feed-O-Matic incorporates a step activated gate to control access to the feed trough.</p> <p style="text-align: justify;">The treadle requires two pounds of weight to open the slide gate. As a chicken steps on the treadle to eat, it is depressed, and the gate opens. When the chicken finishes and steps off, the treadle rises shutting the gate to limit access to lighter weight pests.</p> <p>The trough featu<img class="alignright wp-image-1581 " src="/images/uploaded/wp-content/uploads/2015/03/Feed-O-matic-closeup-300x300.jpeg" alt="Feed-O-matic closeup" width="203" height="203" style="float: right;" />res several refinements to limit feed loss as the chickens are eating. Solid plastic dividers prevent feed from piling up in the corners and falling out. A feed-saving plastic lip on the trough keeps birds from “raking” feed out of the trough as they eat.</p> <p>Constru<img class=" wp-image-1585 alignleft" src="/images/uploaded/wp-content/uploads/2015/03/Feed-O-Matic-lid-open.jpeg" alt="Feed-O-Matic lid open" width="353" height="353" style="float: left;" />cted of 20 ga. galvanized steel, the Feed-O-Matic holds 26.5 pounds of feed.

Polypropylene shades don&rsquo;t dent or corrode like aluminum shades. Plastic shades also have a some cushion or &ldquo;bounce&rdquo; when knocked against the crate or creep panels reducing bulb breakage.</p> <p style="text-align: justify;">The Hog Slat&rsquo;s Poly Lamp improves several key features of the plastic heat lamp, most notably to the nylon fixture.</p> <p><img class=" size-medium wp-image-1596 alignleft" src="/images/uploaded/wp-content/uploads/2015/04/poly-lamp-fixture-300x300.jpg" alt="poly-lamp-fixture" width="300" height="300" style="float: left; padding: 10px;" />First, the nylon fixture screws together on the shade top, instead bolting. The two-piece fixture reduces breakage occurring with the bolt-on style of earlier models.</p> <p style="text-align: justify;">Second, we use a rigid fixture instead the flexible type used on other poly lamps. The rigid design eliminates cord twist when replacing bulbs.</p> <p style="text-align: justify;">And third, the porcelain socket resists heat damage better than plastic types.</p> <p style="text-align: justify;">The Poly Lamp comes with a choice of hanging options; adjustable sliding poly hanger on the 9&prime; cord or a wire hanger mounted on fixture top.</p> <p><img class="alignright wp-image-1597 size-thumbnail" src="/images/uploaded/wp-content/uploads/2015/04/poly-lamp-poly-hanger-150x150.jpg" alt="poly-lamp-poly-hanger" width="150" height="150" style="float: right; padding: 10px;" /></p> <p style="text-align: justify;">Rated a maximum 250 watts at 120 volts, the Poly Lamp is UL listed. The Poly Lamp also comes with an extended<strong>&nbsp;Three-Year Warranty</strong>.</p> <p style="text-align: justify;">Overall the Poly Lamp is an improved version of earlier plastic lamp shades at very attractive price.

Manufactured at our facilities in Iowa and North Carolina, AirStorm fans offer dependable&nbsp;performance at very attractive prices.&nbsp;Here is a&nbsp;look at several key features illustrating the quality designed into AirStorm fans.</p> <p><img class=" wp-image-1610 alignleft" src="/images/uploaded/wp-content/uploads/2015/04/itm-as-36-img-no-shutter-cone-150x150.jpg" alt="itm-as-36-img no shutter cone" width="151" height="151" style="float: left; padding: 10px;" />Quality starts with Resin Transfer Molded (RTM) &nbsp;fiberglass housings. Fiberglass parts produced by a RTM process have two finished surfaces and high glass-to-resin ratio. The result is a very finished looking product with high weight-to-strength characteristics. A direct side-by-side comparison of competitive brands shows AirStorm housings to be noticeably thicker. Polyethylene discharge cones reduce weight and cost.<span style="text-align: justify;">&nbsp;</span></p> <p><img class="alignright size-thumbnail wp-image-1609" src="/images/uploaded/wp-content/uploads/2015/04/itm-as-36-img-back-shutter-150x150.jpg" alt="itm-as-36-img back shutter" width="150" height="150" style="float: right; padding: 10px;" /></p> <p style="text-align: justify;">True airfoil vanes on the PVC shutters reduce air drag to improve fan delivery. Full-length spring steel rods, instead of short endpins, keep the vanes securely mounted into the frame.</p> <p><img class=" size-thumbnail wp-image-1608 alignleft" src="/images/uploaded/wp-content/uploads/2015/04/itm-as-54-img-back-gaurd-150x150.jpg" alt="itm-as-54-img back gaurd" width="150" height="150" style="float: left; padding: 10px;" />Heavy-weight, stainless steel motor mounts, and hardware offer more protection from rust and corrosion than comparable aluminum mounts. Stainless Steel (36&Prime; &amp; 54&Prime;) or composite (24&Prime;) props outlast plastic or aluminum and stay &ldquo;in-balance&rdquo; through actual on-farm conditions. High service factor motors provide protection against varying line voltages common with rural power sources.<span style="text-align: justify;">&nbsp;</span></p> <p><img class="alignright wp-image-863" src="/images/uploaded/wp-content/uploads/2014/07/stack-of-coins-150x150.jpg" alt="stack of coins" width="153" height="153" style="float: right; padding: 10px;" />The lower purchase price of AirStorm fans results from a different type of distribution model. The traditional marketing channel for ventilation equipment consists of a manufacturer selling fans to a local dealer who marks the price up before selling to livestock producers. The cost of AirStorm fans is lower because we manufacture and sell directly to the end user. Hog Slat controls the distribution chain from&nbsp;<strong>start</strong>(manufacturing and sourcing) to&nbsp;<strong>finish</strong>&nbsp;(sale to the end user) and can limit the amount of &ldquo;stacked margins&rdquo; in the final purchase price. (<a href="http://www.hogslat.com/blog/?s=margin+stack">See more about Margin Stack</a>) Our network of local stores provides service at a cost lower than typical dealer distribution systems.</p> <p style="text-align: justify;">For pricing and ordering information go to&nbsp;<a title="AirStorm Ventilation Fans - Hog Slat, Inc." href="http://hogslat.com/airstorm-fiberglass-fan" target="_blank">Airstorm Fans</a></p>urn:store:1:blog:post:89https://hogslat.com/ultimate-chicken-bucket-drinkerUltimate Chicken Bucket Drinker<p><img class="alignleft size-medium wp-image-1626" src="/images/uploaded/wp-content/uploads/2015/04/0004354_chicken-drinking-bucket-with-3-nipples-300x300.jpeg" alt="0004354_chicken-drinking-bucket-with-3-nipples" width="300" height="300" style="float: left; padding: 10px;" /></p> <p style="text-align: justify;">Building a poultry drinker by inserting poultry watering nipples into the bottom of a common five-gallon plastic bucket is very popular for backyard flocks. Bucket waterers are inexpensive, sanitary and relatively trouble-free.</p> <p>We would like to introduce you to an improvement on this simple concept, a product we like to think of as the Ultimate Bucket Drinker.<br /><img class="alignright wp-image-1625 size-medium" src="/images/uploaded/wp-content/uploads/2015/04/Bucket-waterer-with-hen-300x270.jpg" alt="Bucket waterer with hen" width="300" height="270" style="float: right; padding: 10px;" /></p> <p style="text-align: justify;">The Ultimate Bucket Drinker is uniquely designed with three recessed sections with preformed nipple fittings molded into the bottom of the bucket, allowing for easy handling and an effective method for watering backyard flocks.</p> <p style="text-align: justify;">One key feature of the Ultimate Bucket Drinker is the three recessed sections. These allow for the bucket to be placed stably on the ground when filling with water, a feature that is not possible with the standard drinker with nipples screwed into the bottom of the bucket.</p> <p><img class="alignleft wp-image-1627 size-thumbnail" src="/images/uploaded/wp-content/uploads/2015/04/0004356_chicken-drinking-bucket-with-3-nipples_326-150x150.jpeg" alt="0004356_chicken-drinking-bucket-with-3-nipples_326" width="150" height="150" style="float: left; padding: 10px;" />A second benefit of the Ultimate Bucket Drinker is raised watering nipples. This raised design prevents any dirt or debris that is in the water to plug the watering nipples. Instead, any dirt or debris in the water will settle to the bottom corners of the bucket.</p> <p style="text-align: justify;">The nipples themselves are commercial grade; trigger activated with extra top filter. </p> <p>The Ultimate Bucket Drinker includes an easy on/off lid, hanging/carrying handle and adjustable<img class="alignright size-thumbnail wp-image-1628" src="/images/uploaded/wp-content/uploads/2015/04/0004355_chicken-drinking-bucket-with-3-nipples-150x150.jpeg" alt="0004355_chicken-drinking-bucket-with-3-nipples" width="150" height="150" style="float: right; padding: 10px;" />hanging cord, allowing you to regulate the ideal drinking height as your chickens grow.</p> <p style="text-align: justify;">The Ultimate Bucket Drinker goes together fast…no drilling or gluing necessary and costs less than other pre-packaged kits on the market.</p> <p>To order go to <a title="Adjustable 3 Nipple Chicken Drinking Bucket " href="http://hogslat.com/adjustable-chicken-drinking-bucket-with-3-nipples">http://hogslat.com/adjustable-chicken-drinking-bucket-with-3-nipples.</a></p> <p><a title="Adjustable 3 Nipple Chicken Drinking Bucket " href="http://hogslat.com/adjustable-chicken-drinking-bucket-with-3-nipples"></a><br /><iframe width="560" height="315" style="display: block; margin-left: auto; margin-right: auto;" src="https://www.youtube.com/embed/TTEdPRMU8Ic?rel=0" frameborder="0" allowfullscreen="allowfullscreen"></iframe></p>urn:store:1:blog:post:90https://hogslat.com/jet-or-submersible-pump-for-cool-cell-systemsJet or Submersible Pump for Cool Cell Systems?<p style="text-align: center;"><img class="aligncenter wp-image-1653 size-full" src="/images/uploaded/wp-content/uploads/2015/04/jet-vs-sub-pump-e1527339434560.jpg" alt="jet vs sub pump" width="600" height="300" /></p> <p style="text-align: justify;">We spoke with Hog Slat engineers, Tyler Marion and Tim King about the differences between using a jet or submersible pump to fill evaporative cooling systems. Here&rsquo;s a quick synopsis of our discussion.</p> <p style="text-align: justify;">1) Jet pumps are more reliable because they can run dry for a period of time. For instance, if you discover during morning chores a leak occurring overnight had drained the system, a jet pump would still be working. &nbsp; A submersible pump that runs that long without water will need to be replaced.</p> <p style="text-align: justify;">2) Jet pump repairs are less costly. The impeller and motor are two individual components; a bad motor can be replaced separately. Submersible pumps are a single unit.</p> <p style="text-align: justify;">3) Jet pump repairs and service are easier. A jet pump system is all above ground&hellip;a submersible pump must be pulled from the sump for repairs. A drain plug on the GrowerSELECT jet pump allows easy access for service and winterizing.</p> <p style="text-align: justify;">4) The integrated trash basket on a jet pump protects the pump from debris.</p> <p style="text-align: justify;">5) Submersible pumps are designed to move waste water from underground applications; low volumes with high head pressures. Jet pumps are a better choice for evaporative cooling applications as they move larger volumes of water at reduced head pressures.</p> <p style="text-align: justify;">6) One of the advantages cited for using a sump/submersible pump system is the sump acts as an extra reservoir for the system. The bottom trough of an 80&prime; long system holds about 300 gallons of water. A typical sump only holds about 30 gallons; really an insignificant amount. The main purpose of a sump area is to provide a place where a submersible pump can run in water so it doesn&rsquo;t burn up.

Part of the complex was converted to breeding stock production to supply gilts to other company farms. In addition, Prestage launched a unique plan in 2012 to convert some of the existing finishing sites to breeding, gestation and farrowing.</p> <p style="text-align: justify;">Russ Goss, Production Manager along with Todd Griffin, the operation’s Maintenance Manager gave us the details of the conversion.</p> <p style="text-align: justify;">The original finishing sites consist of eight, 40’ x 176’8” buildings designed  to hold 880 head of market hogs.</p> <p><img class="alignleft wp-image-1790" src="/images/uploaded/wp-content/uploads/2013/11/site-drawing-PUB-file-800x566-2.jpg" alt="site drawing PUB file (800x566) (2)" width="428" height="303" style="float: left; padding: 10px;" /></p> <p style="text-align: justify;">First part of the plan consisted of creating a dedicated breeding site at one former finishing site. One of the buildings was left unchanged and used as an isolation unit, with only the original 30″ penning swapped out for 40″ high gestation gates.  The other seven buildings were switched over to breeding with each holding 336 stalls. The sows remain in the stalls for 42 days after breeding. After preg-checking, the sows are trucked to one of the converted gestation/farrowing sites. The gestation and farrowing sites were retrofitted using four of the buildings as farrowing and four as gestation. Each gestation barn is sized to fill two of the farrowing buildings.</p> <p style="text-align: justify;">The gestation floor plan lays out 20) 15’10” wide x 18’6” deep pens with 24) gestation stalls located on one end. . Each pen is designed to hold 14 sows allowing for 21 square foot per animal. Each pen has five feeding stanchions located along the center alley and ten on the outside wall.</p> <p><img class="alignleft wp-image-1791" src="/images/uploaded/wp-content/uploads/2013/11/PRESTAGE-MISSISSIPPI-single-2-1_edited-1.jpg" alt="PRESTAGE MISSISSIPPI single) (2)-1_edited-1" width="692" height="188" style="display: block; margin-left: auto; margin-right: auto;" /></p> <p><img class="alignleft wp-image-1793" src="/images/uploaded/wp-content/uploads/2013/11/stanchion-sows-eating-800x533.jpg" alt="stanchion sows eating (800x533)" width="600" height="400" style="display: block; margin-left: auto; margin-right: auto;" /></p> <p style="text-align: justify;">Adjustable feed drops drop the rations into the stainless steel trough below.</p> <p style="text-align: justify;">When we asked Russ about the decision to go with pen system versus stalls, he explained, “We feel stanchions are the best choice for group housing compared to the ESF options that we looked at. We think stanchions are easier for our staff to manage and there is less equipment to maintain and repair.”</p> <p style="text-align: justify;">Russ commented, “The sows adapt to the stanchions fairly well. There’s some fighting the first day we put them together, but they settle down after that. Without a doubt group housing requires a higher level of stockmanship from our people, but the farm staff has learned to manage the system without a lot of trouble.”</p> <p><img class="alignleft size-full wp-image-1794" src="/images/uploaded/wp-content/uploads/2013/11/farrowing-crates-800x521.jpg" alt="farrowing crates (800x521)" width="800" height="521" style="display: block; margin-left: auto; margin-right: auto;" /></p> <p style="text-align: justify;">Crews removed the old slats and equipment, after opening up a section of the end wall. Supported by the existing slat walls, trussed TriDek flooring spans the entire building with traction brakes located in the center of the crate providing the sows with better footing. Four rows of 33 farrowing crates were installed on the flooring for a total capacity of 132.</p> <p style="text-align: justify;">Prestage selected a 5’x 7’ Advantage finger style crate with stainless steel rear door panels and SowMAX dispensers above the feeders. Four feed lines run the length of the building to fill the dispensers.</p> <p style="text-align: justify;"><img class="alignleft wp-image-1795" src="/images/uploaded/wp-content/uploads/2013/11/sow-max-closeup-683x1024-683x1024.jpg" alt="sow max closeup (683x1024)" width="282" height="423" style="float: left; padding: 10px;" />Russ explained Prestage’s previous experience with SowMAX, “We just do a better job feeding sows in lactation with the SowMAX. It eliminates any guess work; we just fill the hoppers twice a day and the sows eat to appetite. They can eat at night during hot weather, and we know they are getting all the feed they want even on the weekends.”</p> <p style="text-align: justify;">He continued “Improved sow body condition is one of the biggest benefits we get from using SowMAX.

Revolver and Boot Hill are formulation with the same active ingredient, Bromadiolone.&nbsp; Revolver is the soft bait version and Boot Hill comes in either a mini block or pellet place pack.</p> <p><img class="size-medium wp-image-693 aligncenter" alt="New Bait Rotation_edited-1" src="/images/uploaded/wp-content/uploads/2013/03/New-Bait-Rotation_edited-1-300x184.jpg" width="300" height="184" style="display: block; margin-left: auto; margin-right: auto;" /></p> <p style="text-align: justify;">&nbsp;</p> <p style="text-align: justify;"><b>Now producers can add another element, texture into their bait rotations.</b>&nbsp; Note the double orange arrows in the rotation diagram illustrating the possible choices.&nbsp; For example if the first bait used was FastDraw the next choice in the rotation could be either Revolver (soft bait) or Boot Hill (mini blocks) as they both contain a differen active ingredient Bromadiolone.&nbsp; If Boot Hill was selected the next step in the rotation back to Difethlalone could be either FastDraw (soft bait) or Hombre (mini blocks).</p> <p style="text-align: justify;">Also note on the diagram the rodenticide Gunslinger highlighted with the blue circle.&nbsp; We highly recommend Gunslinger be inserted into any bait rotation at clean out as it most effective when animals aren&rsquo;t present and feed sources can be removed. Gunslinger contains a completely different active ingredient, Bromethalin and its &ldquo;knockdown&rdquo; on rodent populations is impressive.</p>urn:store:1:blog:post:5https://hogslat.com/extended-anchor-bearingExtended Anchor Bearing<p style="text-align: justify;">As animal and poultry housing became larger and we develop more sophisticated feeding methods, the use of multiple bins in tandem became common.&nbsp; While this set-up allowed for greater flexibility in feeding, the front bin of the pair was prone to plugging.</p> <p style="text-align: justify;">If we look at the anchor bearing that is present in the rear bin, we would notice that it has a restrictor tube over the shaft.&nbsp; This restrictor tube fills core of the flex auger and prevents feed from filling up the core and overloading the auger.</p> <p style="text-align: justify;">This restrictor is not present in the front bin.&nbsp; When the slide is opened feed overloads the system faster than the auger will move it away.&nbsp; The obvious solution is to cut the opening down by closing off the slide to restrict feed flow.&nbsp; This can cause other problems as a feed flows tends to flow only down one side of the bin.&nbsp; A better solution is to use baffles in the boot to restrict feed flow.&nbsp; This works to prevent plugging but can cause feed bridging in the bin.&nbsp;</p> <p style="text-align: justify;">Over the last several years Hog Slat developed and tested a unique solution to this problem.&nbsp; The final product is called the Extended Anchor Bearing.</p> <p style="text-align: justify;"><img class="alignleft size-medium wp-image-696" alt="feed-bin-auger-drawing-anchor-bearing" src="/images/uploaded/wp-content/uploads/2013/04/feed-bin-auger-drawing-anchor-bearing-300x224.jpg" width="300" height="224" /></p> <p style="text-align: justify;">Described simply, the Extended Anchor Bearing extends the rear tube restrictor to the front bin.&nbsp; The auger core is filled in and feed cannot overfill the system.</p> <p style="text-align: justify;">The Extended Anchor Bearing ships complete with a 14&rsquo; restrictor tube, replacement bearing and fastening hardware.&nbsp; The 14&rsquo; restrictor tube is cut to length and inserted it the auger core.&nbsp; The new bearing is installed and the auger reattached.</p>urn:store:1:blog:post:3https://hogslat.com/blogindexphp20130509105-year-old-texas-woman-reveals-bacon-as-her-secret-behind-long-life105-Year-Old Texas Woman Reveals Bacon as her Secret behind Long Life<p style="text-align: justify;"><b>A 105-year-old Texas woman has earned a place in almost all headlines by revealing the most unlikely secret to her long life.</b></p> <p style="text-align: justify;">Strangely, her key to longevity is bacon. Yes, you read it right; 105-year-old Pearl Cantrell loves to eat bacon and feasts on it almost every day. Her story, for sure, will be a subject of research for most health scientists.</p> <p style="text-align: justify;">Pearl Cantrell, who&rsquo;s mostly referred to as the &rsquo;105-year-old bacon woman&rsquo;, said in an interview with a local NBC station, &ldquo;I love bacon and I eat it everyday. I don&rsquo;t feel as old as I am, that&rsquo;s all I can say.&rdquo;</p> <p style="text-align: justify;">Resident of Central Texas, Cantrell, a mother of seven, has outlived three of her kids, as well as her husband. Her recent 105<span>th</span>&nbsp;birthday bash was a three-day affair that included more than 200 guests.</p> <p style="text-align: justify;">Reports according to KRBC state that Cantrell&rsquo;s love for bacon grabbed the attention of the American meat and cold cut production company Oscar Mayer. A representative of the company was present at Cantrell&rsquo;s birthday. The spokesman reached her home in a Wienermobile and gave the &lsquo;bacon woman&rsquo; a ride in the hot dog-shaped truck, gifting her tons of bacon, with more to come in the future.</p> <p style="text-align: justify;">&ldquo;We&rsquo;ve seen a lot of stories on the road, but nothing quite like this one, so we&rsquo;re excited to be here,&rdquo; Abraham Luna, one of the representatives, told KRBC, of the 105-year-old bacon woman. &ldquo;Pearl is an inspiration for the community, and her friends and family, so we had to make a special stop here for her today.&rdquo;</p> <p style="text-align: justify;">Cantrell&rsquo;s daughter Anno says that her mother taught them to work hard and think about living everyday they woke up. She never spoke about dying. She is very active and still loves to dance.</p> <p style="text-align: justify;">This story comes as a challenge to the latest study conducted by the University of Zurich, which clearly states that eating too much bacon elevates the risk for bowel cancer.</p>
