Study’s findings will be presented Nov. 16 during K-State Swine Day

Oct 30, 2023

As the U.S. swine industry shifts toward improving gut health in newly weaned pigs to decrease mortality rates, a Kansas State University student is studying ways to incorporate low acid binding ingredients into swine diets.

Ethan Stas, a graduate research assistant in K-State’s Department of Animal Sciences and Industry, said acid binding ingredients are key to a concept known as acid-binding capacity, or ABC-4, which looks at the pH level of a pig’s stomach before the animal’s gastrointestinal tract matures.

“ABC-4 is the amount of hydrochloric acid required to reach a stable pH of 4 for an ingredient or diet,” he said. “For swine, we utilize a pH of 4 because once the pig's stomach increases above (that level of acidity), this is where impaired nutrient utilization and health problems can occur.”

Video: Managing Severe PRRS Outbreaks - Dr. Claire Mtezankuni

In this episode of The Swine it Podcast Show Canada, Dr. Claire Mtezankuni, Swine Veterinarian at Carthage Veterinary Service, discusses the growing severity of PRRS outbreaks in sow farms. She explains how respiratory disease and sow mortality are changing outbreak response, why necropsies and bacterial cultures can guide treatment, and how vaccination, biosecurity, pain management, and clear team communication support recovery and elimination. Listen now on all major platforms!

“Emerging PRRS strains can produce severe reproductive and respiratory disease simultaneously, creating substantial health challenges across sow farms during acute outbreaks.”
