The pastures were grazed until July 13. The steers in four pastures received a basic mineral mix with 800 mg of Bovatec7 per lb. The other four pastures received the basic mineral mixture with Bovatec plus 1.6 lb Aureomycin 50 per 50 lb of mineral. The steers receiving the mineral with Aureomycin had greater mineral consumption (P<0.04). Including Aureomycin in the mineral increased gain by 2%; however, the response was not statistically significant.BeefBovatecIonophoreAureomycinAntibioticNative grassConference paper
