| 摘 要： | 用欧拉羊杂交改良乔科羊,生产的欧乔杂交F1代羔羊,18月龄时公、母羊体重增加9.06kg和3.77 kg,比对照组分别提高了20.92%和9.08%。试验组F1代18月龄公、母羊体重、体高、胸围及公羊体长极显著的高于对照组(P(0.01);母羊体长显著高于同期对照组母羊(P(0.05)。屠宰试验结果表明,欧乔杂交F1代18月龄公、母羊屠宰前活重比同龄的乔科羊对照组后代分别高8.94 kg和6.00 kg,胴体重比同龄的乔科羊对照组后代分别高4.88 kg和3.27 kg,差异极显著;屠宰率比同龄的乔科羊对照组后代分别高1.43%和1.10%,差异不显著。

| Abstract: | Oula Tibetan sheep was used to improve Qiaoke sheep, Oula sheep x Qiaoke sheep breeding offspring Fl lamb, body weight of 18 - month - age increased 9.06 kg and 3.77 kg, respectively, which improved 20.92% and 9.08% respectively comparing to control group. Fl generation body weight, body height, chest length and body length were significantly higher than control group （P 〈 0. 01 ） ;female sheep body length was significantly higher than control group （P 〈 0.05 ）. Slaughter experiment indieated that F1generation 18 - month - age male and female sheep live weight before slaughter was higher than Qiaoke sheep 8.94 kg and 6.00 kg for the same age, carcass weight were higher than Qiaoke sheep 4.88 kg and 3.27 kg for the same age, the difference was significant; dressing percentage was higher than control group for 1.43% and 1.10% respectively, the difference was not signifieant. |
