摘　　要：研究营养水平(A因子:A1为1.0倍NRC、A2为0.9倍NRC、A3为0.8倍NRC)和性别(B因子:B1为公羔、B2为母羔)对策勒黑羊羔羊生产性能的影响及经济效益分析。结果表明,A1B1组羔羊试验末体重分别较A1B2组、A2B1组、A2B2组、A3B1组、A3B2组羔羊提高6.17%、7.44%、12.84%、14.29%、17.22%;A1B1组羔羊平均日增重分别较A1B2组、A2B1组、A2B2组、A3B1组、A3B2组羔羊提高20.87%、17.06%、34.89%、37.35%、39.62%;A1B1组羔羊料肉比分别较A1B2组、A2B1组、A2B2组、A3B1组、A3B2组羔羊降低28.24%、23.96%、62.47%、63.84%、62.96%。根据经济效益分析可知,A1B1组羔羊纯收入分别较A1B2组、A2B1组、A2B2组、A3B1组、A3B2组羔羊增加17.13%、28.19%、41.58%、40.24%、42.69%。由试验可知,采用1.0倍NRC的饲粮饲喂的策勒黑羊公羔羊生产性能和经济效益较高。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.
