杜湖杂种公羊与湖羊杂交试验

Hybridization Experiment on Rams in F_1 Generation (Dorper Sheep and Hu Sheep Crossbred) and Hu Sheep

选择体况良好健康的周岁湖羊母羊120只分为A、B、C三组,每组40只作为本试验的母本群。A组为湖羊纯繁(湖湖),B组为杜湖F1公羊湖羊母羊,C组为F2代公羊湖羊母羊。试验在全舍饲条件下进行,全程饲养管理条件相同。经过11个月的试验,测定各组母羊繁殖性能及所产羔羊初生、1月龄、2月龄、4月龄和6月龄的体重,体尺,通过数据比较,得出杂种后代的生产性能优于湖羊纯繁后代。

120 ewes （Hu sheep） at one-year-old in good body condition were divided into three groups as the female parent. Group A is pure breeding of Hu sheep （Hu sheepHu sheep）. Group B is F／-I rams of Dorper sheep and Hu sheep Hu sheep e-wes. Group C is F2 rams Hu sheep ewes. Experiment conducted in a dry-lot and at the same feeding management. The trial lasted for 11 months. Reproductive performance of ewes and body weight, body size of lambs at born, 1-month-old, 2-month old, 4-month-old and 6-month - old were measured. Comparing the above data, we concluded that the production performance of hybrid progeny is better than that of pure Hu sheep offspring.
