Efficacy and Compatibility of Amprolium and Carbarsone Against Coccidiosis and Blackhead in Turkeys

Abstract

Amprolium and carbarsone were tested separately and in combination for efficacy in prevention of occidiosis and histomoniasis, respectively. In these studies, amprolium at .0125% in the diet was efficacious in prevention of coccidiosis, and carbarsone had no deleterious effects when fed simultaneously at .0375%. Carbarsone at .0250% was efficacious in prevention of histomoniasis, and amprolium had no deleterious effects when fed concurrently at .025%. These results indicated that both drugs could be used in combination without interference of efficacy against the target diseases.
