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.
