摘要：

为了优化祁连山高寒牧区肉羊生产杂交模式，2008年-2010年连续3年以特克塞尔、白萨福克、邦德和澳洲美利奴4个引进品种为父本、甘肃高山细毛羊为母本，采用AI技术开展杂交试验。生长观测表明，特甘细羔羊断奶体重为27.71 kg，极显著高于其他组合；6月龄体重达到31.04 kg，比邦甘细、白萨甘细、澳甘细和对照组分别高出8.79%、14.15%、18.42%和33.97%。屠宰结果表明，特甘细的胴体重、屠宰率、胴体净肉率、骨重和眼肌面积均最大，骨肉比最小。同时，特克塞尔杂种羔羊肉的pH值、嫩度等肉品质指标较优。由此表明，“特克塞尔X甘肃高山细毛羊”是祁连山高寒牧区生产优质羔羊肉的最优杂交组合，特克塞尔是改良甘肃高山细毛羊的最优父本。

Abstract:

In order to optimize the hybrid pattern of lamb production in alpine pastoral area of Qilian mountains, a 3 years field experiment was conducted to observe 4 cross combination (Texel、White Suffolk、Bond and Australia Merino were used as male parent，and Gansu Alpine Merino was used as female) by the method of artificial insemination from 2008 to 2010. The results showed that the weaning weight of Texel F1 was 27.71 kg, being significantly higher than the other combinations. The 6-month-old weight of Texel F1 was 31.04 kg, which was higher than Bond、White Suffolk、Australian Merino and the control group for 8.79%, 14.15%, 18.42% and 33.97%, respectively. The carcass weight, dressing percentage, net meat percentage, bone weight and loin muscle area of Texel F1 were the highest, but the ratio of bone to meat was the least. Meanwhile, the pH value and tenderness were better than the others. Therefore, the Texel was the best male，and the group of the Texel X Gansu Alpine Merino was the ideal cross combination for lamb production in alpine pastoral area of Qilian mountains.
