祁连山高寒牧区杂种羔羊生长及肉用性能分析

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×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,...

Summary: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×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。

In order to optimize the hybrid pattern of lamb production in alpine pastoral area of Qilian mountains, a three 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 were 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% ,
