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 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.

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.

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.

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.

Two critical design elements have proved themselves in the existing layouts.  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.

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.

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.

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.

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.

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.

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.

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.

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 10 ozs.!! Less weight equals less fatigue at the end of the day.

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.

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

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.

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. It is water-proof, lightweight and easy to keep clean.

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.

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.

As the food industry responds to animal welfare issues, many producers have started to consider alternative options to stall-based gestation systems. We took a few moments to speak with Hog Slat’s national sales manager, Fritz Richards, about group housing systems.
Can you describe the options available and the advantages and disadvantages of each?
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.

Like?
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 successfully. With many production systems experiencing high turnover of farm staff, it becomes very difficult to perform the necessary maintenance and training.

Where do you see ESF working best?
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.

What other options have you looked at?
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.

Are Free Access Stalls available from Hog Slat?
We offer this equipment to producers, but, they need to remember 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.

What other options are available?
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.

What seems to be the most popular option?
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.

Why do you think it is so popular?
Stanchion production methods adapt well to current U.S. production practices. A farm’s current staff can manage a stanchion system because it utilizes the same feed delivery system and penning equipment as they are currently using.

What criteria are used in designing a stanchion system?
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.
A group sizing of 10 to 20 head per pen is common. Equipment is standard 40-inch high rod panels with 18” long divider stanchions, creating a feed space for each animal in the pen. The stanchions are open rod style set at 18” to 21” 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’t restrict air flow as much as solid panels. In addition, rod style penning is more cost effective and has a longer life span.
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.

How is the stanchion system managed?
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’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.
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.

Are there any disadvantages?
Yes, animals cannot be individually fed. Sows that “fall out” 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 to move into group housing.

How many stanchions have been installed by Hog Slat?
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.

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.  We all know that we should change v-belts on belt drive fans when they get worn but….why?

V-belts don’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’s just like the pulley becoming smaller. As the fan spins slower it 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 capacity of a building by 10% can spell disaster in terms of pig and broiler performance during the heat of the summer.

How do you know when to replace a V-belt? 

A quick visual check will determine if  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’s time to replace the V-belt.

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.

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’t make it to a local store, you can also order on line at http://www.hogslat.com/v-belts-grobelt-drive-belts and we’ll ship them directly to your door.

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.

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!”

I recently caught up with Mark Daughtry of Prestage Farms in North Carolina to discuss his experience with SowMax farrowing ad lib feeders.  Mark is the Sow Production Manager in North Carolina and oversees about 55,000 sows.  He quickly corrected my terminology regarding the SowMAX.

“First of all…” Mark said, “the SowMAX is not a sow feeder.  It’s a feed storage device that delivers feed to the sow on demand. It’s like having a bunch of MINI FEED BINS sitting above the feeders ready to deliver fresh feed on demand.

“I’m not sure exactly what you mean.”

Look I’ve been working with sow herds for 24 years in one way or another. The BIGGEST challenge I’ve faced in that time has been training farrowing house personnel to feed lactating sows.  It is extremely difficult to feed sows correctly by hand.

Sows are individuals and depending on their genetic makeup some sows are capable of eating much more feed on a daily basis than the group.  If you were to look at daily feed intake per sow, you would see a normal bell curve.  The bulk of sows will eat somewhere between 18-22 pounds per day, but some of those gals will eat as high as 30 pounds a day! Those are the sows that normally don’t get fed correctly with hand feeding.

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.  Those are the sows that will typically wean desirable large litters of heavy pigs.

I like to think of today sows as being like high performance race cars.  If we don’t fuel up a race car, it will not run.  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.

How does that change with SowMAX?

SowMAX allows us to feed sows to full appetite without guess work.  Our feeding regiment in farrowing goes like this:

For three days prior to farrowing we feed four pounds of feed through the SowMAX.  We instruct the farrowing personnel to place two pounds, twice a day in the SowMAX hopper.  This gets them up each time and gets them accustomed to activating the trigger lever on the SowMAX.

After farrowing, we continue to hand feed for two more days.  On day three, we fill them up and monitor feed disappearance.

Feed disappearance? What does that mean?

Simply put it means that we fill the SowMAX up twice a day and look the amount feed that is gone in the hopper.  As long as the sow is eating over half of that amount we just fill it up again and go on.  We are only concerned with the sows that aren’t eating; that’s the one that’s having trouble and needs our attention.

“You know Mark, feed is very expensive; what about a producer’s concern that SowMAX may be getting more feed into the sows but that it’s also wasting more feed?”

Our experience has shown the exact opposite.  We waste less feed with SowMAX than hand feeding, and that’s easy to figure out.  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.  The SowMAX delivers fresh feed to the feeders….on demand….whenever a sow is ready to eat.   Human judgment is eliminated….we don’t have to try and outguess mother nature. Again, we have those MINI FEED BINS sitting there ready to deliver feed whenever she’s ready to eat.

Do you have farms with other types of systems?

Yes, we have automatic systems where feed is dumped from drops into the feeders several times a day.  There is less physical labor but it really isn’t any better than hand feeding.  You still have to guess on the amount of feed each sow will consume each day.  Plus, as the systems get older they take more maintenance; it seems like we are always fixing a switch or replacing a motor. SowMAX works everyday; no timers, no motors, no switches, nothing to wear out.

With SowMAX, we fill the hopper, and we have some flexibility if something goes wrong.  In a dire emergency, we still have almost a day’s worth of feed storage at each hopper.  We have other systems that use a plastic tube and have almost no storage.  We have a lot more cushion with SowMAX than the other systems.

So with SowMAX, you are able to “fuel up the race cars” What differences do you see in performance?

First, there are only two things that make milk, feed and water.  A sow produces more milk per body weight than a milk cow.  Can you image a dairyman limit feeding a milk cow?  That would never happen, yet we expect a sow to produce to her full genetic potential on limit feeding!  SowMAX allows us to fully feed sows according to their individual appetite and they produce heavier litters.

Second, we quit condition scoring sows coming out of the farrowing crates that are using SowMAX.  Rarely would we have a Two score, they consistently scored as Threes. Because of their better body condition rebreeding is improved.

We have SowMAX in about 5,000 crates in North Carolina.  You can bet that any updates or remodels that we do in the future will include SowMAX feeders also.
