Abstract: Effects of different nutrition levels （A 1 for 1.0 times NRC, A2 for 0.9 times NRC and A3 for 0.8 times NRC）and gender （B1 for male lamb and B2 for female lamb） on the production performance of Cele black sheep lamb and economic benefit were studied. The results showed that at the end of the test weight of the A1B1 group lamb was increased by 6.17%, 7.44%, 12.84%, 14.29% and 17.22% ,respectively, compared with that of A1B2, A2B1, A2B2, A3B1 and A3B2 group lambs,and average daily gain of the A1B1 group lamb was increased by 20.87%, 17.06%, 34.89%, 37.35% and 39.62% ,respectively ,compared with that of A1B2, A2B1, A2B2, A3B1 and A3B2 group lambs ;feed conversion ratio of the A1B1 group lamb was decreased by 28.24%, 23.96%, 62.47%, 63.84% and 62.96% ,respectively,compared with that of A1B2, A2B1, A2B2, A3B1 and A3B2 group lambs. According to economic benefit analysis, net income of the A1Blgroup lamb was increased by 17.13%, 28.19%, 41.58%, 40.24% and 42.69% ,respectively,compared with that of A1B2, A2B1, A2B2, A3B1 and A3B2 group lambs. The results indicated that Cele black sheep male lamb fed by 1.0 times NRC can obtain good production performance and higher economic benefit.
