Why Control Liver Abscesses?

Liver abscesses cost the US beef industry around $256 million annually with costs attributed to liver and offal condemnation ($72.3 million) and processing speed delays ($11.6 million)2. The hidden cost of liver abscesses lie in excess carcass trim, which are often not reported back to the producer, and are estimated to cost the industry $35.1 million annually3. Liver abscesses also rob feedyard profitability before the processing plant, with studies finding a loss in average daily gain of 5.3 percent (0.17 lb) in animals with A+ liver abscesses4.

Directions for Use:

For reduction of incidence of liver abscesses of cattle fed in confinement for slaughter: Feed 85-240 mg/hd/day at 13.5-16.0 g/ton of complete feed (90% dry matter basis).

Important Safety Information:

  • Caution: Federal law restricts medicated feed containing this veterinary feed directive (VFD) drug to use by or on the order of a licensed veterinarian.
