摘 要:本试验对照组选用周岁湖羊母羊40只进行纯繁,试验一组选用湖羊母羊40只与周岁杜泊公羊杂交生产杂种一代(以下简称F1代),试验二组选用杂种一代(F_1)母羊40只周岁与周岁杜泊公羊杂交生产杂种二代(以下简称F_2代)。试验在全舍饲条件下进行,全程饲养管理条件相同。经过11个月的饲养试验,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,得出杂种后代和湖羊纯繁后代的增重比较结果。This experiment,40 ewes of one-year-old Hu sheep were used for pure breeding as the control group.40 crossbred generation sheep(F1)by Hu sheep at one-year-old×Dorper sheep with one-year-old were selected as the first group.40 crossbred generation sheep(F2)by F1 at one-year-old×Dorper sheep at one-year-old as the second group.The experiment were conducted at whole barn feeding conditions and the same managemengts.After 11 months of feeding experiment,we measured the production performance of all groups and the body weight body size of lambs at birth,one-month-old,two-month-old,four-month-old and six-month-old.According to the above data,We obtained the results of gain weight of hybrid progeny sheep and Hu sheep pure breeding generations.
