Effect of medicated mineral mixtures and a pinkeye vaccine on the gain and health of steers grazing native grass pastures

Abstract

Feeding supplements containing an antibiotic or ionophore improved stocker gains by .06 to .26 lb per head daily. A combination of Bovatec and Aureomycin in the mineral mixture improved (P<.08) steer gains over feeding Aureomycin alone. Mineral intake was higher than expected for the steers grazing burned, double-stocked) native grass pastures in 1987. Vaccinating steers with Piliguard at turn-out had no effect on pinkeye incidence and reduced stocker gains slightly.
