摘要
试验以引进的优良肉羊品种特克塞尔和杜泊羊为父本(♂),以小尾寒羊为母本(♀)进行杂交,所生产的杂交一代羔羊进行肥育。试验设3个组合。试验组I(特寒羊):特克塞尔绵羊(♂)×小尾寒羊(♀);试验组Ⅱ(杜寒羊):杜泊绵羊(♂)×小尾寒羊(♀);对照组Ⅲ为小尾寒羊本交羔羊。在舍饲饲养管理条件下,测定其杂交一代(F1)肉羊的体重、饲料转化率和肉用性能等。试验结果表明:杜寒F1的多个性状均优于特寒F1,差异显著(P<0.05),试验组与对照组相比较,差异极显著(P<0.01)。
Fattening experiment of Crossbred F1 lamb from introduced good breed Dorset and Dorper sheep as male parent（♂）and Small-tail Han sheep as female parent（♀） was conducted.In this study,three groups were set.Test group I（Dorset ♂×Small-tail Han sheep ♀）,Test group Ⅱ（Dorper ♂×Small-tail Han sheep ♀）,Control group（Ⅲ,Small-tail Han sheep ♂×Small-tail Han sheep ♀）.Body weight,feed conversion ratio and mutton production performance of F1 offspring were measured under house management.The results showed that multiple traits of F1 from Dorper×Small-tail Han sheep were better than that from Dorset×Small-tail Han sheep（P0.05）,there was significant difference between test groups and control group（P0.01）.
