摘要
本试验旨在比较不同杂交组合的杂交优势,在提高小尾寒羊生长性能、屠宰率等方面的不同特点,以推动杂交优种普及,促进肉羊产业发展。选用优秀杜泊、萨福克公羊作为父本,以小尾寒羊为母本,进行杂交,测定杂交一代肉羊的体尺、体重、屠宰性能等指标,并与小尾寒羊自繁进行比较,以评定杂交改良的效果。试验结果表明:在相同的饲养管理条件下,杂交肉羊在成活率、体重、体长、胸围、日增重、屠宰性能等指标上,与小尾寒羊相比均差异显著(P<0.05),且具有体长,胸围宽阔等肉用性能特点。
This study aimed to evaluate the effects of different hybridization combination of Small-tail han sheep on growth performance and slaughter rate etc.,to improve the popularization of good hybrid and further promote mutton sheep industry.Dorper and Suffolk,as male parents,were hybridized with Small-tail han sheep,as female parent,then determined the body size,weight,slaughter performance,etc.of F1 and the self-reproduction of Small-tail han sheep and evaluated the effect of crossbreeding.The results showed that there were significant differences between the hybrid sheep and Small-tail han sheep(P<0.05)in survival rate,body weight,body length,chest circumference,daily gain,slaughter performance etc.with the same feeding and management conditions.The hybrid sheep has excellent characteristics,such as body length and wide chest circumference.
