Abstract

A finishing study evaluated the effects of shade and feeding zilpaterol hydrochloride (ZH) on performance, carcass quality, mobility, and body temperature. No effect on body temperature, or performance was observed for shaded cattle versus cattle in open pens. Feeding ZH increased HCW, LM area and decreased yield grade. Zilpaterol hydrochloride increased respiration rate but did not significantly affect body temperature or mobility. Across all treatments mobility decreased with time, therefore, cattle were least mobile at the time of harvest.
