| 摘 要： | 为了筛选适合贵州生产的三元杂交肉牛,试验选用利木赞牛、安格斯牛和夏洛莱牛冻精对西本母牛进行杂交改良.试验结果表明：不同杂交组合后代犊牛均表现出明显的杂种优势,从初生到18月龄,夏西本牛的体重、体尺指标均最优,依次为利西本牛、安西本牛、西本杂牛;3组三元杂交牛不同月龄的体重、体尺指标均差异不显著（P＞0.05）,但均显著高于西本杂牛（P＜0.05）.结论：虽然夏西本牛的体尺指标和生产性能最好,但由于其产犊难产比例较高,且当地养殖户不喜欢其白色的被毛,因此建议在本省推广利西本牛、安西本牛.

| Abstract: | In order to select suitable for the production of three crossbred beef cattle in Guizhou, this experiment selects Limousin, Angus cattle and Charolais cattle frozen semen for Simmental - local cattle crossbred cattle for crossbreeding. The results showed that, different generations of hybrid calves showed obvious heterosis, from birth to 18 months of age, Charolais - simmental - local cattle crossbred cattle body weight, body measurement index optimization, followed by Limousin - simmental - local cattle crossbred cattle, Angus - simmental - local cattle crossbred cattle, Simmental - local cattle crossbred cattle; 3 groups three different crossbred cattle weight, body sizes were not significantly different（ P 〉 0.05 ） , but were significantly higher than simmental - local cattle crossbred cattle （ P 〈 0.05 ）. Conclusion, although Charolais - simmental - local cattle crossbred cattle body size index and production performance of the best, however, due to a higher proportion of their calving dystocia, and local farmers do not like their white coat, therefore suggested in this province to promote Limousin -simmental -local cattle crossbred cattle, Angus -simmental - local cattle crossbred cattle. |
