Liver Abscess

Liver abscess is a disease marked by inflammation and necrosis of the liver. 

Lesions that occur on the liver are pale yellow, often spherical with necrosis of the liver cells and the surrounding area which leads to inflammation of the liver.  

Abscesses are found in all ages and breeds of cattle and under all types of management, but most cases are found in beef cattle from feedlots due to a high grain content diet.  

Feedlot cattle with abscessed livers have reduced feed conversion efficiency, and those with severely abscessed livers gain 5–15% less per day than cattle without abscesses, reducing production rate and resulting carcases weight. 

Fusobacteriumnecrophorum, an anaerobic bacteria, is the primary agent of the disease. 

The disease is initiated by a physical opening in the rumen outer layer, allowing bacteria that is normally contained to enter the blood steam. 

Acidosis is often the first step in creating an entrance point for bacteria in the rumen.  

No obvious clinical signs on farm or in feedlot. However, maybe suspected due to reduced production efficiency.  

Disease is found at slaughter when the whole liver is condemned due to abscess in the liver.  

Difficult to diagnose liver abscess.  

Preventative measures are often undertaken rather than treatment.  

Treatment usually involves antibiotics, but should only be used in consultation with your veterinarian. 

Change of diet is key to preventing the acidosis that leads to liver abscesses occurring. An increase in fibre and a decrease in the amount of carbohydrate-rich grain provided should minimise of the incidence of liver abscesses in cattle.  

Consult with your veterinarian about nutritional management and other preventative measures
