Researchers Race Against the Clock to Discover Preventive Measures for Liver Abscesses in Cattle

Jun 02, 2025

Researchers at the USDA’s Agricultural Research Service (ARS) are looking to help the U.S. food industry save millions annually by reducing liver abscess formations in cattle.

The prevalence of liver abscess formations in cattle continues to raise concerns among dairy and beef producers. This problem also remains a challenge for researchers, as the primary factors driving formations are not yet fully understood.

Reducing liver abscess formation is even more critical in calves born from dairy cows mated with beef sires (“dairy-beef crossbred cattle”). These crossbred calves are becoming a greater percentage of the total beef population in the beef industry and are also shown to be more susceptible to this problem [close to 50% vs 20% for traditionally raised beef cattle].

Video: Refeeding Syndrome After Weaning - Dr. Theo van Kempen

In this episode of The Swine Nutrition Blackbelt Podcast, Dr. Theo van Kempen, an independent consultant with extensive swine nutrition and product development experience, explains how refeeding syndrome can affect newly weaned piglets. He discusses phosphate depletion, edema, intestinal health, oxygen delivery, and high-glycemic nursery diets, and presents nutritional strategies designed to reduce postweaning challenges.

“Refeeding syndrome develops when feeding resumes after fasting, creating an acute phosphate deficiency as metabolism rapidly accelerates and cellular phosphate requirements increase.”
