Effects of zilpaterol hydrochloride and virginiamycin on growth performance, carcass characteristics, and visceral organ mass in feedlot lambs
Zilpaterol hydrochloride (0.20 mg/kg of live weight/d, equivalent to 7.55 mg/lamb/d) and virginiamycin (22 mg/lamb/d) improved growth and energy retention, but only zilpaterol improved dressing percentage and reduced fat traits of carcass and non-carcass components. The effects of virginiamycin and zilpaterol were found to be cumulative, with better responses in growth and dietary energy components observed in lambs supplemented with both additives.
