A.S. Series 72-28
Hormone and hormone-like compounds are commonly used for feedlot heifers. Effects on feedlot performance and carcass characteristics appear to vary depending on compounds used, levels administered including frequency of implanting, stage of growth and fattening, and dietary conditions. This experiment was one in a series to study the effects of melengestrol acetate (MGA) and implants of diethylstilbestrol (DES) or zeranol administered to heifers during growing and finishing or during finishing only.
