Precision feeding for swine offers benefits

Swine herd nutrient requirements and manure nutrient excretions reduced through management practice

Individually formulated diets can reduce swine’s nutritional needs and the nutrient content of manure, a recent Swine Innovation Porc study showed.

Scientists are developing the technology to create swine diets that are custom-made for the nutritional needs of each pig in the herd, a Farmscape article said last week.

Researchers can now estimate daily nutrient requirements.

“We can reduce, by at least 25 per cent, the amount of protein that we have to give to the overall group,” Dr. Candido Pomar, a research scientist with Agriculture and Agri-Food Canada, said in the article.

In conventional systems, all pigs are fed the same diet. However, some pigs need more nutrients than others so herd diets are formulated to meet those higher requirements.

“When we move to precision feeding, then we have the possibility of identifying the nature of each pig and then to provide them daily with the diet that they need,” Pomar said in the article.

Producers can use precision feeding to provide less demanding pigs less nutrient-dense diets, which means lower costs, the release said.

Through reducing the nutrient content of feed, pigs may emit less nutrients from manure.

“Because we are feeding pigs with less nitrogen, less protein, less nitrogen (and) less phosphorus, then we are also reducing nitrogen and phosphorus expression,” Pomar said.

This precision feeding strategy could reduce the levels of these nutrients in manure by around 30 to 40 per cent, which would benefit the environment, he said.

The scientists involved in this study will conduct more research on pig physiology and how they utilize nutrients. Researchers could then further reduce the nutrient requirements of pigs, as well as nutrients in manure.

CEOs of the Industry, we sit down with Dr. Jay Miller, CEO of The Maschhoffs, to explore his remarkable journey from veterinary consultant to executive leader at one of America’s largest family-owned pork production companies.

Dr. Miller shares how his outside-in perspective shaped his leadership approach, what it was like transitioning from advisor to CEO, and how he’s balancing the company’s proud multigenerational legacy with the need for transformation and innovation.

We dig into tough topics like navigating company contraction, reshaping culture for performance, and the critical role veterinary expertise plays at the executive level. Dr. Miller opens up about building a sustainable, modern pork business—not just environmentally, but operationally and culturally—and what it takes to attract and develop the next generation of talent in agriculture.

Looking ahead, he shares his five-year vision for The Maschhoffs and gives us a personal peek in the Fast Five round, where he reveals leadership insights, the best advice he’s received, and the three words that define The Maschhoffs in 2025.
