摘要
[目的]探讨弗莱维赫牛改良贵州本地黄牛的效果。[方法]以弗莱维赫牛为父本,分别与本地黄牛(♀)、西本杂(西门塔尔牛×本地黄牛,♀)杂交,测定其杂交后代的生产性能、屠宰性能及泌乳性能,并与贵州本地黄牛进行比较。[结果]F1弗莱维赫牛(♂)×西门塔尔牛(♂)×本地黄牛(♀)杂交后代的生长性能、屠宰性能及泌乳性能最优,F1弗莱维赫牛(♂)×本地黄牛(♀)杂交后代次之,本地黄牛最差。[结论]以弗莱维赫为父本杂交改良本地黄牛及生产三元杂交牛(弗×西×本),其后代具有明显的杂种优势,能显著提高肉牛养殖的经济效益。
[Objective ] The research aimed to discuss the improvement effect of Fleckvieh crossbred with Guizhou local yellow cattle.[Method] With Fleckvieh as male parent,they were crossbred with Guizhou local yellow cattle（♀）,Simmental ×local yellow cattle（♀） to determine the growth performance,slaughter performance and lactation performance of their offspring.And they were compared with Guizhou local yellow cattle.[Result] The growth performance,slaughter performance and lactation performance of F1 offspring of Fleckvieh（♂）×Simmental（♂）×local yellow cattle（♀） was the best,followed by the offspring of Fleckvieh（♂）× local yellow cattle（♀）,and the offspring of Guizhou local yellow cattle was the worst.[Conclusion] Guizhou local yellow cattle was improved by crossbreeding with Fleckvieh（♂） to produce the hybrids of Fleckvieh × Simmental× local yellow cattle.The offspring had obvious heterosis and the economic benefits of beef cattle farming could be significantly enhanced.
