Swine nutrition tips during a down market

There’s no question the US swine industry is struggling through a down market cycle. Jason Woodworth, research professor at Kansas State University, spoke to attendees at the Annual Four Star Pork Industry Conference held in Muncie, Indiana in September 2023 about nutritional strategies for feeding pigs during a down market.

“Unfortunately, the goal may be to lose the least amount of money that you can during this time, and we have to look through that lens at the idea of profitability,” said Dr. Woodworth. “Our reality is that we’re going to be on the bottom side of zero, and we’re trying to conserve as much as we can. I’d encourage producers to be as nimble and flexible as possible and to try to take advantage of what’s going on in the market as well as what’s happening in your barns.”

Get the basics right
Taking care of pigs is a producer’s core job, so it’s important to stay focused on feed, water and the environment. Following are suggestions to consider and monitor in your barns:

Proper feeder and feedline setup uses all the feeder spaces and keeps feed available to the pig. Woodworth says if the feed isn’t getting to the pigs, you’ve got trouble. He shared an example of a five-hole feeder that’s only has feed coming out of two holes. It’s critical to get back in the barns, inspect your feeders and make sure they are working properly. Dr. Woodworth suggests empowering your barn team to fix anything that seems broken and give them the time and tools to catch some of the feeder issues. A reminder to the barn team about “why” this is economically important to the operation is essential to get their buy-in.
Partially filled pens don’t work well with some feeders. The picture identifies an example of a lot of wastage because the pen on the bottom side was understocked. You have pigs on the fully stocked side turning the lever and running feed while the pigs on the other side can’t consume that much feed. Walk through the barns with a fresh set of eyes to evaluate what’s going on and where you see inefficiencies.
Adjust the feeders frequently. A properly adjusted feeder can have a big impact on feed wastage and a big impact on feed efficiency from a nursery perspective. Target feed pan coverage is 40% to 50% without feed accumulating in the corners when the pigs are placed into the nursery. The newly weaned piglets aren’t strong enough to work the gates on the feeders. But once you get to the end of finishing, about 20% to 30% of pan coverage is needed to be able to minimize feed wastage and maximize the amount of feed you want consumed by pigs to support the level of growth needed.
Is it time to replace old feeders? It’s important to consider what an inefficient feeding system is really costing you. Dr. Woodworth has created a chart that shows the extra feed cost per feeder per year that you may be paying if your feeders are not working well. Diet cost is on the left of the chart; the top is deviations in feed efficiency. For example, if you are giving up 0.10 in feed efficiency, and your average diet cost is $300, then in this grow-finish barn, you’re putting $500 of feed into the pits for every feeder in that barn on an annual basis. Producers often think replacing their older feeding system is very costly, but when you consider $500 of wastage per feeder, then that improvement can pay for itself.

Revisit feeder space and stocking density recommendations. Woodworth shared a feeder management guide and reminded producers to make sure they have the right number of feeder spaces per pig and the right amount of space per pig and that pigs have easy access to the feeders.

Easy access to water. Oftentimes water is considered the forgotten nutrient. Ensuring clean water is getting to animals to support their growth is essential. He said this summer he was assisting with a farm that had been experiencing poor growth, scours, and sows losing weight for about six months. He said they’d looked at every nutritional reason or disease that may have caused the symptoms that were seen. The problem turned out to be plugged water lines due to extensive corrosion in the pipes. Thus, the water intake on those sows was very limited. They weren’t eating; they weren’t making enough milk; piglets weren’t growing. They cleaned the lines and went through the barns and changed out all the water nipples and practically overnight things changed for the operation. He also reminded producers to make sure that gilts know where to find water nipples and how to get water from them. Being in a farrowing crate is a new experience for gilts and access to water is really important, especially for gilts, so help them find and use the nipples.
Consider environmental opportunities. Woodworth shared a recent trial of Pillen Family Farms showing the use of detergent prior to power washing. Ultimately, about a three-cent per pen costs in detergent resulted in a reduction of mortality by 1.1%. They attributed this to about 58 cents per pig through their value system, just by spending that three cents per pen to apply the detergent. Especially in down markets, we start looking at ways to cut costs and save every penny we can, but don’t get so ingrained with that mindset. Be open to considering all your options and understand the difference between a cost and an investment that results in additional return.
Particle size. Woodworth says he can’t stress enough the importance of proper particle size. Producers will see about 1% improvement in feed efficiency for every 100 microns of grain particle size that is reduced. For every 100 microns of higher particle size than the goal, about seven pounds of extra feed per pig is required to achieve the same amount of gain. That means about $1.05 per pig at a $300 feed cost is wasted because the feed is not ground to the target particle size. He recommends routine assessment and monitoring of particle size. The target is to get down to a 500-to-600-micron particle size, and he says that’s about as low as you can go with meal-based diets. Any smaller and you may experience feed flowability issues. However, pellets give you a little more leeway. Getting the right particle size for your pigs will help improve feed efficiency and minimize excess costs.
