Hog Slat offers Additional Options for Swine Watering
Single and Double Welded Cups

Single and Double Welded Cups

Hog Slat highlighted an additional watering option for finishing pigs at the 2016 World Pork Expo. This all stainless steel welded cup is available in single and double models and designed with several features producers will appreciate.

Note formed gap in back plate

The back plate of welded cup is formed with a gap off the gate to allow any manure accumulating there to be easily washed out. This prevents premature rusting of gate rods common with cups mounted back to back without this gap.

The unique design of the two-piece water pipe allows for easy replacement if it should ever become damaged or bent. The separate ½”x 48” long pipe installs into a female coupler on top of the cup. A specially designed bracket is included to mount the pipe to the top angle on a gate.

 

Mounting cups back to back is simple with four bolts or single cups can be mounted with a U-bolt around a horizontal gate bar.

2nd Gen Sensor featured in GrowerSELECT Feed Line Control
GrowerSELECT Proxy Control at the 2016 World Pork Expo

GrowerSELECT Proxy Control on display  at the 2016 World Pork Expo

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.

The GrowerSELECT Proximity Drop Tube Control features a flat proxy sensor that can detect feed levels through the plastic housing. The flat proxy mounts to the side of the feed tube and doesn’t require drilling a hole for installation. The compact design takes up less room on the control compared to rod type proxy sensors.

GrowerSELECT HS572

GrowerSELECT HS752

Encapsulated solid state sensor has no moving parts and doesn't need adjustment.

Feed Chain Torture Chamber

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.

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.

Chain-Disk-torture-_blur.web

“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.”

Chain-Corner-w_-Filings_web

“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.”

“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.”

Compare-three-chains_web

“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.”

We next looked at how well the plastic disks are fastened to the chain.

“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.”

Chain-Disk-link_web

“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.”

“First of all, the disks are manufactured from nylon, a stronger, denser plastic instead of polypropylene.
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.”

Chain-Link-closeup_web

“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.”

“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.”

You can be confident using Grow-Disk chain knowing you are buying the very best even though the cost is usually less.

Hog Slat streamlined distribution system reduces margin stacking.  We manufacture and source products direct to you….eliminating extra dealer margins.

Hog Slat Supply Chain

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.

2015 World Pork Expo Hog Slat Display

2015 World Pork Expo Hog Slat Display Booth

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 fansGrow-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.GrowerSELECT Iowa Finish Barn
Both of these deep pit barns were equipped with GrowerSELECT Grow-Flex™ feed systemsHog 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.

DIY Gating Repairs from Hog Slat

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.

Cut and Weld

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.

Comparing 17 Year Old Slats

I have sold or been involved with swine concrete slats for over 30 years.  For the last 18 of those years I have represented Hog Slat products.  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?

Last week I was at  Hog Slat’s production plant in Humboldt, Iowa taking pictures of slats.  The plant manager, Dave Shiflett said “You want to see some old slats that we pulled out of a barn recently?”

“Sure”

So we go out behind the plant and he explained that we were called in to replace some slats from local production site.  This particular site was built in 1994. One barn has slats produced by Hog Slat and the other barn has slats from a competitor.

Comparing slats

He said “The slat on the left is a Hog Slat slat and the one on the right is from the competitor.  Notice the difference in surface wear on each slat.  The competitor’s slat has rock showing because the top surface has been eaten or worn away.  I grabbed our slat out of the other building that they were not replacing for comparison.”

“Interesting, but they’re not from the same building”

“No but same site which means same water, same feed and same management.  Pretty good comparison of 17 years old slats I would say”

So we started talking about the reasons for the better wear on the Hog Slat product.

Dave said “It’s the denser concrete we use in our mix.  Everybody that has ever poured any concrete knows the less water you use in mixing concrete, the harder, stronger concrete you get.  The standard mix is a 4” slump, which you have to use to be able to place and screed the concrete in the form.  We use a ZERO SLUMP mix in our slats. Let me show you what I mean inside.”

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” concrete mix.

concrete slump

“Note how the concrete mix on the right has sagged down 4” vs. the zero slump concrete on the right? All the rest of the slat manufacturers have to use a wetter mixture because they don’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.”

As the industry’s production buildings get older this comparison bears keeping in mind.  Most new slats look the same when they are placed in the barn and you really can’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.  Looking at 17 year old slats is a chance to get some valuable insight that may help with that decision.

Stop Pouring Money Down the Pit

With feed costs reaching an all time high, having the right feeder in your swine facility has never been more important.  Historically American growers have enjoyed low feed costs compared to the rest of the world’s producers.  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’t meet industry standards for ADG and Feed Conversion.

The charts below show Agri-Stats Top 25’s average for Feed Conversion for both Feeder to Finish and Wean to Finish operations.  We can use them as a baseline to compare to potential savings that can be achieved with good, well designed feeders.

Using these numbers let’s compare potential savings on a typical 1,200 head finishing building with 20 feeders.  For our example let’s assume that the barn is showing an average feed conversion of 2.9 , achieves 2.4  annual turns and replacing the feeders moves the FC to 2.6.

1,200 head x $24.64 saved per pig space =$29,568

To replace those 20 Feeders with Hog Slat 60” feeders would cost $5,940.

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.  That means you would have to own the feeders for only 73 days to recoup your investment of $5,940!

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.

The bolt together construction adds durability that you can’t get with a welded feeder.  Heavy weight hogs bang and push against feeders.  Welded feeders don’t have the ability to flex with the blows and stress cracks can develop.

Hog Slat feeders have a deeper trough than most competitive brands and a feed saver lip preventing pigs from rooting feed out.

Hog Slat’s box feeders provide higher storage capacity than most tube style feeders.  The large storage volume contributes a safety factor for feed availability issues such as bin bridging, broken augers or motors and power failures.

Precise management of the feeder adjustments is absolutely critical to achieving good feed conversions.  Every Hog Slat feeder features our unique Select-A-Flow adjustment which gives producers the ability to make fine graduated changes in feed flow.  Each numbered setting presents 1/16” in feeder gate adjustment.  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.   You can’t get this kind of repeatability using feeders designed with crank type adjustments.

Hog Slat feeders have been the industry standard for the last 25 years.  Replace your existing feeders and stop pouring money down the pit.

2012 World Pork Expo…260 lb. burgers, $2,000 bin whackers and ESF.

The 2012 Pork Expo is in the books.  Great weather this year and great food.  Especially the 260 lb pork burger Vinny and crew from Hog Slat cooked up.  This wasn’t just an inedible gimmick either…..the slice I had was very good.

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……mechanical bin whackers in other words. One rep explained that his product was a much better choice than his competitor’s model and “ours is only about $1200 compared to theirs at $2000.” Wow. The price of the anti-bridging device is almost as much as the bin.

Quite a few companies displayed their version of Electronic Sow Feeding (ESF).   One says each feeding station will handle 60-65 sows, the next guy’s will handle 300.   All the computerized systems are easy to use; intuitive I believe was the term they used.  Everybody had a “system expert” who probably lives several states away from your farm.

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 now.

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.

Sort Barn Remodel

In 2005 Dustin Anderson and Paul Anderson came to an agreement on a  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.   Part of the agreement included each of them constructing a 2,498 head finishing house with Dustin managing the sites.

original sort barn

Dustin explained “The integrator that we fed with at the time spec’ed a sort barn system and we constructed the facilities according to the standard plan. The sort barn was different from what we were used to managing.  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.  In addition, anytime the pigs became sick, the whole barn would refuse to go into the food court.  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!”

“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.”

Dustin continued, “Several years ago we changed companies and quickly found out our feed conversion and rate of gain were not measuring up.  In order to compete, we felt we needed to convert to a more typical pen layout.

“We called our local Hog Slat rep, Wade Finch, when we got serious about doing the retro.  Wade measured up the rooms and met with us several times before we decided on a final layout.  We set up the rooms with a center alley and 18 pens measuring 18’8” wide X 23’9” long holding 65 head each.

     

In addition, we created four “sick pens” that are 9’4” wide.

We also added extra gating by the feeders so we can shut off the front of the pen and presort for load out.

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.”

Justin was just starting to sort pigs out of the first remodeled barn the day of my site visit.  When I asked about the results he replied, “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’ll start selling the first group out of the remodeled barn at 13 weeks, and I’m sure the last pigs will be gone at 15 weeks. Chores are much easier; I can see all the pigs and treat sick ones without having to chase them around.”

“Now that I see the results, I wish I would have done it several years ago!”
