摘　　要：对欧拉羊与山谷型藏羊杂交试验组和山谷型藏羊本交对照组所产的后代进行了初生、3月龄、6月龄、12月龄、18月龄的体重跟踪测定和差异显著性检验。结果表明,欧山杂交F1代公、母羊初生～3月龄,3～6月龄,6～12月龄、12～18月龄日增重分别比同期对照组后代日增重均快,差异极显著(P﹤0.01),并且随着月龄的增加,日增重降低。说明欧山杂交后代的生长速度在初生至12月龄增长速度快,而12～18月龄的增长速度减慢,适宜羔羊肉生产。Offspring measurements of birth weight, 3-month, 6-month, 12-month and 18-month weight for Euler Sheep and Valley-type Tibetan Sheep crossbreeding and control group were conducted. The results showed that daily weight gains of F1 （Oula× Valley-type Tibetan Sheep） were significantly higher（P〈0.01） than control group （Valley-type Tibetan Sheep natural mating） from birth to 3-month old, from 3 to 6-month old, from 6 to 12-month old, from 12 to 18-month old. Moreover, with the increasing of age, daily weight gain decreased. Growth rateof F1 crossbreeding was fast from birth to 12-month old age, which decreased from 12 to 18-month old, and su~,table for mutton production.
