New studies aim to solve cattle liver abscess mystery

By Farms.com

Liver abscesses represent a critical issue in cattle farming, affecting both the well-being of animals and the financial health of industry. In an unprecedented collaborative effort, scientists from the USDA and various universities are delving into the causes and development of liver abscesses in cattle. Their research aims to create effective models to study this condition, shedding light on how to prevent it. 

A notable achievement of this collaboration is the establishment of a liver abscess model that demonstrates a consistent 50% prevalence rate. The research primarily focuses on the dietary causes and bacterial involvement in liver abscess formation. High-grain diets have been identified as a possible risk factor due to their impact on rumen pH levels, potentially facilitating bacterial infections that lead to abscesses. 

The findings have also introduced the possibility that the primary bacteria involved in these abscesses might come from parts of the gastrointestinal tract other than the rumen, challenging previous assumptions and indicating new directions for prevention and treatment. 

This quest for knowledge extends beyond the academic realm, aiming to replace antibiotic treatments with more sustainable solutions, such as adjustments in nutritional management. Such advancements could lead to significant improvements in cattle health and welfare, while also addressing public concerns over antibiotic resistance. 

This groundbreaking research underscores the importance of scientific collaboration in addressing complex agricultural challenges. By understanding the intricacies of liver abscesses in cattle, the agricultural community hopes to develop innovative, effective strategies for prevention and treatment, ensuring the sustainability and profitability of cattle farming.

Video: Genetics Behind Swine Resilience - Dr. Jenelle Dunkelberger


In this episode of The Swine it Podcast Show Canada, Dr. Jenelle Dunkelberger, geneticist at Topigs Norsvin, explains how genetics can improve disease resilience in pigs. She explores how resilience differs from resistance, the role of genetic variation, and how breeding strategies can enhance health and performance under disease pressure. Dr. Dunkelberger also covers practical applications and future implications for swine production. Listen now on all major platforms!

"Controlled experimental trials confirm that differences in mortality and performance under disease pressure are linked to genetic background, even when environmental conditions remain consistent."

Meet the guest: Dr. Jenelle Dunkelberger / jenelle-dunkelberger-9200ab86 is a geneticist at Topigs Norsvin, where she leads the Global Health and Behavior Research Platform. She earned her PhD from Iowa State University, focusing on host genetics and disease response in pigs. Her work centers on improving swine health and performance through genetic selection for resilience and behavior traits.
