Evaluation of Bambermycins (GAINPRO®) as a Feed Additive in Receiving Rations for Beef Calves
Abstract
Three-hundred-forty-eight newly weaned beef calves were used in duplicate 28-day experiments to evaluate GAINPRO®, Aureomycin, or no feed additive. Diets fed were formulated to provide 14.5% crude protein (CP) and .48 megacalorie per pound net energy (Mcal/lb. NEg) . Aureomycin reduced (P < .05) average daily gain (ADG) for the first 14 days compared to GAINPRO® or no feed additive. This effect disappeared by 28 days on feed, and ADG favored (P < .05) Aureomycin-supplemented calves compared to those given no feed additives. Calves receiving GAINPRO® fell between the two treatments for 28-day ADG.
