摘要：
Non-pregnant beef heifers implanted with zeranol at birth and at 100 and 200 d of age were fed a finishing ration for 78 d to slaughter at 21-22 mo of age. Rate of fat deposition, grade fat and marbling score were less (P < 0.05) and carcass weight, rib-eye area and lean-meat yield were greater (P < 0.05) for implanted heifers than for non-implanted heifers.
