How the U.S. pork industry can make an additional $250 million

It's not news that keeping sows in the herd longer is a smart strategy. Not only have older sows covered their investment costs, they have a greater capacity to produce larger litters with heavier weaning weights. But how can an additional litter impact the industry's bottom line? And what does an ideal parity structure look like?

Jon Bergstrom, Ph.D., senior technical support manager for DSM Nutritional Products, says an extra litter from each sow could generate additional income very quickly. 

"If each sow in the U.S. produced one more litter in her lifetime, the U.S. swine industry would generate another $250 million of net value for the pork industry," he says, crediting the fact that sows past parity 3-4 have met their breakeven point and started generating profit.

The Current Gap

The room for economic growth is highlighted by a gap in potential and performance, shown through PIC data in Figure 1.

"The suggested performance target for optimal profit is to have an average herd parity of 3.5," Bergstrom says. "But even the top 25 percent of U.S. farms are only at an average herd parity of 3. Many farms are below an average of 3. These sows are not even reaching their breakeven point before being culled."

Similar early culling trends are shown when looking at average age of removal from the herd. The PIC target for sow removal is 5.5 years of age; however, the best in the business are culling sows at an average age of 4.5 years old.

"Why are we not achieving our performance targets and the goal of 30 percent or fewer voluntary culls? Because we have far too many sows being removed for poor reproduction, locomotion problems or simply poor performance," Bergstrom says.

Working Toward Ideal Parity Structure

Though higher parity sows are generally more profitable, Bergstrom says there are benefits to raising healthy gilts as well. Gilts and lower parity sows are equally as important as high parity sows because they represent the newest genetics and are the future of the herd. For this reason, a balanced parity structure with representation from all ages is ideal, as shown in Figure 2.

"If fed correctly, the higher parity sows are better able to perform today, while the gilts are the future economic generators of the herd," Bergstrom says.

To promote balance in the herd, Bergstrom recommends formulating rations based on parity. An often overlooked part of this formula is high-quality vitamins and minerals.

"If we feed sows to restrict energy intake and manage body condition, the amount of vitamins and trace minerals per pound of body weight declines for older sows unless we make adjustments to the diets they are going to be fed," he says. "We need to make sure we are feeding sows adequate levels of high-quality nutrients, including vitamins and trace minerals, that are needed to support sow longevity and a greater number of healthy piglets. The correct nutrition is the fuel that will help them reach their genetic potential."
