[ 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 x 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 F, offspring of Fleckvieh (♂ ) x Simmental (♂ ) x local yellow cattle (♀ ) was the best, followed by the offspring of Fleckvieh (♂ ) X 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 x Simmental X local yellow cattle. The offspring had obvious heterosis and the economic benefits of beef cattle farming could be significantly enhanced.%[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.
