Liver Abscess Research Points to a New Culprit

A new study featured in Hoard’s Dairyman Intel is shaking up what we thought we knew about liver abscesses in cattle. For years, the main blame went to high-grain diets causing ruminal acidosis. But fresh research led by USDA microbiologist Rand Broadway—alongside Texas Tech University, Texas A&M University, and Kansas State University—tells a different story.

“Our research indicates that pathogen presence alone is sufficient to cause an abscess. Therefore, if we can reduce the pathogen load and block its pathway to the liver, we can control the problem.”

It’s Not Just About Diet

The study found Fusobacterium and Salmonella in many abscesses. These bacteria are already present in cattle environments, and they may reach the liver through the bloodstream or via lesions in the digestive tract. The research also points out that stress— from weather swings, illness, or gut inflammation— can make it easier for these pathogens to take hold.

In other words, while nutrition still matters, simply managing diet isn’t enough. Pathogen control needs to be front and center.

Why This Matters for Prevention

This shift in understanding means prevention starts earlier than many might think. The focus now is on reducing the bacteria that can cause trouble and blocking the routes they use to get to the liver.

By tackling pathogen control before problems start, producers can help protect cattle health and avoid costly losses.

How Our Tools Fit In

• Sync – Sync Products provide optimal ingredient combinations and potency when overwhelming numbers of pathogens in maternal colostrum threaten calf health and survival. Sync products help to establish or re-establish beneficial microbial populations in the new calf’s MicroBiome.
• Surveillance Calf – Is designed to give calves a strong start by supporting gut health, pathogen control, and reinforcing immune function. A well-balanced gut in the first weeks of life helps reduce the risk of harmful pathogens establishing themselves-setting calves up for healthier growth and long-term resilience.
• TomaHawk iL – Focuses on maintaining a healthy digestive environment and supporting liver health. By promoting a balanced microbial population in the gut, it helps limit pathogen load and reduces the opportunity for those pathogens to travel to the liver and cause damage.

Together, they help producers do exactly what the research recommends: lower pathogen load and stop it in its tracks.

The Bottom Line

The new USDA-led research makes one thing clear—liver abscess prevention isn’t just about feed. It’s about finding and fixing health challenges early so pathogens never get the chance to cause damage.
