摘 要:试验结果表明:陶×欧F1的初生重较欧拉羊提高了0.59 kg,差异显著(P<0.05);在相同的饲养管理条件下,4月龄陶×欧F1羔羊与欧拉羊相比,体重提高了10.58%,差异显著(P<0.05);体长、胸宽和管围分别提高了7.75%、1.19%和7.46%(P<0.01);尻宽提高了4.35%(P<0.05),6月龄测定表明,F1的体重提高了14%(P<0.05),体长、胸宽和管围分别提高了10.07%、8.79%和4.11%,(P<0.01);尻宽提高了4.66%(P<0.05);10月龄测定显示,F1的体重提高了10.91%(P<0.05),体长、胸深和管围分别提高了7.99%、7.05%和6.49%(P<0.01),尻宽提高了18.8%(P<0.05)。The experimental results showed that the birth body weight of F1 of Dorset )× Oura improved by 0. 59 kg than that of Oura sheep with significant difference(P〈0. 05). Under same feeding condition, the body weight, body length, chest width, cannon circumferend and thurl width of F, at 4-month-old of Dorset XOura respectively improved by 10.58% (P〈0.05), 7.75% (P(0.01), 1.19% (P〈0. 01) ,7. 46% (P〈0.01) and 4.35% (P〈0.05) than those of Ourasheep. Those ofF, at 6 month age of Dorset×Oura respectively improved 14% (P〈0.05), 10.07% (P(0.01), 8.79% (P〈0.01), 4.11% (P〈0. 01) and 4. 66%(P〈0. 05) than those of Oura sheep, while those of Flat 10-month-old of Dorset×Oura respectively improved 10.91% (P〈0.05), 7.99% (P〈0.01), 7.05% F1(P〈0.01), 6.49% (P〈0.01) and 18.8% (P〈0.05) than those of Oura sheep.
