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

Jun 02, 2025

By Maribel Alonso

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: Environmental Effects on Sow Fertility - Dr. Isabela Bez

In this special episode celebrating International Women's Day of The Swine it Podcast Show Canada, we bring Dr. Isabela Bez, a veterinarian and PhD student in Brazil, who explains how temperature and light regimes influence sow reproductive performance. She discusses seasonal infertility, climate adaptation, and why environmental monitoring inside barns is critical for herd efficiency. The episode highlights practical management strategies to reduce reproductive losses and improve outcomes. Listen now on all major platforms. "Environmental factors are actually very important on sow reproduction, and sometimes these are the factors that producers tend to not pay attention." Meet the guest: Dr. Isabela Bez / isabela-cristina-cola%c3%a7o-bez-1753381b0 is a veterinarian and PhD student in Animal Science at Pontifical Catholic University of Paraná (PUCPR), Brazil. Her work focuses on swine reproduction, nutrition, and animal welfare, with strong expertise in environmental effects on sow performance. She collaborates with international farms and research groups to improve reproductive efficiency through applied science.
