摘　　要：利用安格斯牛冻精与斯布牦牛经济杂交,研究杂交效果及其F1生长发育情况,选取健康无病经产斯布牦牛50头,对其同期发情处理后进行人工授精。F1代的受胎率为10%,成活率为100%;F1代安犏牛的初生体质量、6月龄体质量、12月龄体质量、18月龄体质量和体质量增加量均极显著高于斯布牦牛的42.79%,80.64%,157.58%,86.22%和91.38%;F1代安犏牛6月龄和18月龄的体尺均极显著高于斯布牦牛。安格斯牛与斯布牦牛杂交生产的F1代安犏牛,杂种优势明显,生长发育良好,具有较强的适应性能。[Objective]Economic hybridization of Angus cattle frozen semen with Sibu yak was used to study the hybridization effect and F1 growth and development.[Method]Fifty healthyand disease-free Sibu yaks were selected and treated with estrus synchronization before artificial insemination.[Results]The conception rate and survival rate of F1 generation were 10%and 100%,respectively.The birth weight,6 monthold weight,12 monthold weight,18 month old weight and weight gain of F1 generation were significantly higher than those of Sibu yak by 42.79%,80.64%,157.58%,86.22%and 91.38%.The body size of F1 generation at 6 and 18 months of age was significantly higher than that of Sibu yak.[Conclusion]The F1 generation of Angus cattle crossbred with Sibu yak has Obvious heterosis,significant growth advantageand strong adaptive performance.
