摘  要:本研究选用凉山半细毛羊对昭觉县本地绵羊进行改良,并对其后裔初生重、周岁重、成年体重、繁殖性能等指标进行观测,结果表明,凉×本F1代初生重平均为3.62±0.45 kg,较本地绵羊2.44±0.36 kg高出48.36%;周岁重较本地绵羊增加9.49 kg,提高27.07%;成年体重较本地绵羊增加11.98 kg,提高25.91%;产羔率、繁殖率和繁殖成活率分别比本地绵羊提高26.32%、28.77%和28.18%;剪毛量平均为3.37±0.46 kg,较本地绵羊增加0.94 kg,提高38.68%;8月龄肥育公羔体重达47.67±0.28㎏,屠宰率为50.98%,分别比本地绵羊提高18.39%和6.13%。凉×本杂交优势明显,值得大力推广。The experiment of Liangshan semi-fine wool sheep improving local sheep was implemented in Zhaojou County.The results showed that the average birth weight of Liangxin F1 generation was 3.62±0.45 kg,48.36%higher than that of local sheep of 2.44±0.36 kg.Increased by 9.49 kg,27.07%higher than that of local sheep for one-year F1 generation sheep.Adult body weight was 11.98 kg,increased by 25.91%higher than that of local sheep.Lambing rate,reproductive rate and reproductive survival rate were increased by 26.32%,28.77%and 28.17%,28.88%,34.82%and 35.74%,respectively.Compared with local sheep,the average shearing wool weight was 3.37±0.46 kg,which was 0.94 kg(38.68%)higher than that of local sheep.The weight of 8-month-old fatten male lamb is 47.67±0.28 kg,and the slaughter ratio of 50.98%,which is 18.39%and 6.13%higher than that of local sheep,respectively.
