摘　　要：本试验研究了小尾寒羊纯繁(Ⅰ组)一元杂交、小尾寒羊(♀)×陶塞特(♂)二元杂交(Ⅱ组)、陶寒(♀)×特克赛尔(♂)三元杂交(Ⅲ组)三种模式下的繁殖效率及其经济效益。结果表明,在相同的饲养管理条件下,小尾寒羊纯繁的每胎产羔数和年产羔总数最高,但是,其所产羔初生重和生长速度最低。此外,无论是在3月龄前还是6月龄前,三元杂交的羔羊日增重最高,二元杂交次之。对每只母羊净收入分析,发现养殖模式以陶寒(♀)×特克赛尔(♂)三元杂交的收入最高(1367.1),小尾寒羊(♀)×陶塞特(♂)二元杂交次之(1322.7),小尾寒羊纯繁最低(866.5元)。In this study, we investigated the breeding efficiency and economic benefits of three patterns of sheep hybridization： pure-breeding of Small Tail Han sheep （Group I, one-way crossbreed）, Small Tail Han sheep （ ♀ ）×Tausert （ ♂ ） （Group n, two-way crossbreed）, and Tao Han （ ♀ ） ×Texel （ ♂ ） （Group Ⅲ, three-way crossbreed）. The results showed that under the same feeding and management conditions, the number of litters and the total number of litters per year were the highest in Group Ⅰ, but the birth weight and growth rate of the litters were the lowest. In addition, the Group Ⅲ had the highest daily weight gain before either three months old or six months old, followed by Group Ⅱ. By analyzing the net income of each ewe, the highest income was found in the Group Ⅲ of Tao Han （ ♀ ） × Texel （♂ ） with 1 367.1 RMB per year, followed by Group Ⅱ of Smalltail Han sheep （♀） × Dosset （ ♂ ） with 1 322.7 RMB per year, and the lowest was Small Tail Han sheep pure-breedin of Group Ⅰ, only 866.5 RMB.
