摘要：The effects of terbutaline (T), metaproterenol (M) and low energy diet (LE) on growth performance and carcass composition were evaluated in 72 Moghani culled ewes. T and M each one at the doses of 0, 5, 10 and 20 mg/ kg DM (C, T5, T10, T20, M5, M10 and M20 respectively) were added to the diet (ME: 2.9 MJ/Kg DM) of seven groups of 63 culled ewes and the other group was fed on LE (ME: 2.5 MJ/Kg DM) for the final 8 wk of the fattening period. T10 and M20 increased (p dry matter intake than controls (1126 vs. 1500 g/day). Except for T5 and LE, all beta-adrenergic treated groups showed improved (p feed conversion , increased carcass meat and lowered weight of-fat tail. Metaproterenol was more effective on feedlot parameters and carcass characteristics than terbutaline and low energy diet.
