FDA approved using Aureomycin® (chlortetracycline) and Bovatec® (lasalocid sodium) in the same cattle feed.
The approval is expected to help producers optimize weight gain and feed efficiency while controlling anaplasmosis, coccidiosis and the leading causes of bacterial enteritis and pneumonia, product manufacturer Alpharma reports.
In an 82-day trial conducted by Kansas State University, grazing steers fed Aureomycin (350 mg per head daily) and Bovatec 30 grams per ton of feed achieved an average daily gain that was 10 percent higher than unmedicated controls 2.64 pounds of gain per day vs. 2.40.
FDA approved varying combinations of Aureomycin 50, 70, 90 and 100 grams per pound formulations and Bovatec 20 grams per pound liquid and 68 and 91 grams per pound formulations for use in Type B and Type C medicated cattle feeds.
Depending on dose rate, Aureomycin may be used for treating bacterial enteritis caused by Escherichia coli and bacterial pneumonia caused by Pasteurella multocida in calves, beef and non-lactating dairy cattle. In beef cattle, it can also be used to control active infection of anaplasmosis caused by Anaplasma marginale and bacterial pneumonia associated with shipping fever complex caused by Pasteurella sp.
