Another successful show is in the books for Hog Slat at the 2015 World Pork Expo in Des Moines, Iowa. This year, Hog Slat displayed several new items, including our AirStorm fiberglass ventilation fans, Grow-Disk™ chain disk feed system and the GrowerSELECT® curtain machine. In addition to these new products, we also featured our concrete slats, TriDek flooring, group pen feed stanchions, GrowerSELECT sow drops and more.

Hog Slat hosted a group of Chinese pig farmers that were visiting the United States and attended the World Pork Expo. On Tuesday, as part of their trip, we visited a brand new 2 barn finishing site Hog Slat just completed, located in Lohrville, IA. The group was able to see a new group of pigs that had just been loaded into one of the barns earlier that afternoon, and also examine the inside of the other barn that had not been loaded with pigs yet.
Both of these deep pit barns were equipped with GrowerSELECT Grow-Flex™ feed systems, Hog Slat wet/dry hog feeders and AquaChief cup waterers as part of their equipment package. The group was very impressed with the fit and finish of Hog Slat’s feed system equipment and building construction. To learn more about new construction or remodeling hog barns in the Midwest or other areas of the United States, please visit the Hog Slat sales representative locator, found here.

Sow and Piglet Performance during Lactation for SowMAX Self Feeders and Hand Feeding

A synopsis of research study conducted at North Carolina State University.

The main objective of this study was to collect lactation and rebreeding data from sows fed with SowMAX self feeders opposed to sows that were hand fed. 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. 

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.

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.

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.

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.

Hog Slat's Cut & Weld panels enable you to build DIY steel gates for your hog farm. Cut & Weld panels feature a movable end to create customized lengths. They're in stock at a local Hog Slat store or online at www.hogslat.com/dyi-gates-and-posts.

The FARMSTEAD chickens are doing great and growing quickly! Through weeks 2 and 3 they have started growing feathers and losing their fuzz. The easily adjustable legs on the Comfort Heating Plate for Chickshave been raised twice now to accommodate their growth and keep the heating plate at the optimum height for our birds. They are easily able to walk underneath the heating plate or lay on the edges to fine tune their comfort levels.

In case you are trying to decide if the Clear Cover for the Comfort Heating Plate is worth purchasing, the answer is “absolutely.” Chickens have a natural urge to roost and desire to perch on an elevated surface. 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 “streaks” 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!

Our chicken drinking bucket with 3 nipples 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 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.

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. 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.

“It just does what it is supposed to. That bucket is way better than what I was using before!” 

We received a photo from a happy customer who purchased the poultry drinking bucket with 3 nipples to put in his outdoor brooder. He is currently brooding a small group of mallard ducklings and a special wood duck duckling, which he rescued from the side of the road after seeing the rest of its flock get hit by a car while crossing a busy road. “If you’ve ever raised ducks before then you will agree they are much messier than chickens! The watering jars and founts I was using wouldn’t last more than a few minutes before the ducks had knocked them over or made a mess in them,” he said. “Ever since I installed the bucket I can fill it up and it will last 2 or 3 days. I don’t have to worry about whether my birds have water when I am gone during the day.”

If you’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 http://www.hogslat.com/farmstead-equipment and purchase yours today!

We’ve got chickens!

This spring we added a few new items to our FARMSTEAD Equipment 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.

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.

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.

Many people use a heat lamp and heat bulb 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 Comfort Heating Plate for Chicks, 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.

In addition to the energy saving and safety benefits the Comfort Heating Plate provides, the chicks absolutely love it! 

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.

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!

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.

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 infrared thermometer.

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.

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 http://www.hogslat.com/comfort-heating-plate-for-chicks to purchase yours today!

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 drinking bucket and hanging feeder you see in the pictures above!

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 filled with pigs again. Even though pigs are hard 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 Cut and Weld panels. Cut and Weld panels allow producers to build gating “on-site” to the exact length needed.

Cut and Weld panels are available in two lengths; 6’-9’ and 9’- 12’ long. Cut and Weld panels are a standard 31 ½” high panel with one end upright tacked in place instead of welded solid.

You simply tap the upright loose and slide it along the horizontal rods until you reach the length desired.

You then weld the rods to the upright and top angle and cut off the excess.

Then, depending on the application, you can choose from a full range of tabs, pipes, latches, etc. to complete the gate. Finish the project off with a coating of Hog Slat blue spray paint to help prevent rust and you’re ready to install a gate fitted to the exact size you needed.

The DIY Cut and Weld panels and all the accessories are in stock at every Hog Slat store located in the Midwest.

Everyone knows that water-powered medicators are the easiest way to administer a wide variety of medications, vaccinations and supplements. 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.

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.

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” up from the bottom of the stock tank so that heavy debris is not sucked up into the medicator.

Always be sure that your maximum flow rate stays within the maximum capacity of your medicator. Be sure to check with your medicator’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.

One of the most important things you can do to protect your medicator is to keep up the medicator’s maintenance schedule, which you should be able to get from your medicator’s manufacturer.

Flushing your medicator with clear water may be the single most important tip I can give.

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’ll make sure that your medicator continues to work hard for you for years to come.

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 7th.  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.

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.

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.

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.

A catwalk is built inside to allow access to inlet filter boxes.

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.

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.

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.

Pre-filters are installed over the filters to prevent clogging of the system by dust and debris.

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.

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.

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. 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.
