EFFECTS OF SALINOMYCIN AND LINCOMYCIN UPON PERFORMANCE, MORTALITY AND INTESTINAL LESION SCORE IN BROILER CHICKENS USING AN IN-FEED COCCIDIA MODEL

Autor: B. I. Groves, C. A. Hammant, R. K. Wheelhouse

Publikováno v: Canadian Journal of Animal Science. 65:255-258

A floor pen trial using an in-feed coccidia model was conducted to determine the efficacy of salinomycin at the rate of 60 mg/kg of feed and to ascertain any interference of lincomycin at 2.2 mg/kg upon salinomycin efficacy in broiler chickens. Inclu
