Study: Increasing frequency of meals may help pregnant sows

Kansas State University swine nutritionists are making progress on studies that look at the best strategies for feeding sows prior to giving birth, work that they say will impact survivability and productivity in all phases of swine production.

Jason Woodworth, a swine nutritionist with K-State Research and Extension, says a trend toward increased litter sizes has led to challenges with lower birth weights, increased pigs born dead and longer farrowing periods for the sow.

"So, we're trying to find ways that we can help overcome these challenges without negatively impacting sow performance or adding unnecessary costs for the swine producer," Woodworth says.

Woodworth and his colleagues on K-State's swine team will present recent findings on feeding sows just prior to farrowing during the university's annual Swine Day, which will be held online only on Nov. 18-19.

"We have conducted a couple of large transition sow studies with commercial partners and have another one happening right now," Woodworth says of the university's trials with feeding pregnant sows.

There are several other studies taking place around the world on this topic, he says.

"Collectively, it does not appear that there is any specific diet formulation change that is the magic bullet to resolving the challenges faced by the sow prior to giving birth," Woodworth says. "However, we have learned that how we feed the sow is important; increasing the frequency of meals has shown the greatest benefit. Instead of feeding one meal per day — which is common — feeding sows two to four meals results in better performance."

He notes, however, that like all research, newer findings can change recommendations and it's important for swine producers to stay current through such events as Swine Day.

Registration for this year's event is available online. Organizers say they have had a record response to this year's online format; as of Nov. 12, they have 750 registrants, including more than 300 from 35 countries.

Woodworth's presentation will take place Nov. 18 during a series of 15-20 minute presentations focusing on applied swine nutrition. The Nov. 19 presentations focus on feed safety and feed processing.

More information on swine nutrition also is available online from K-State's Department of Animal Sciences and Industry.
