摘　　要：为了探讨西门塔尔牛和安格斯牛杂交改良本地黄牛效果,采用西门塔尔牛和安格斯牛作为肉牛终端父本,分别与本地黄牛开展二元经济杂交,对杂交F1体重变化、屠宰性能数据进行了统计分析研究。结果表明:两者杂交F1均比本地黄牛生长速度快且产肉率高,可有效提高本地黄牛的屠宰性能。说明西门塔尔牛和安格斯牛改良本地黄牛杂交优势明显,可有效增加本地黄牛养殖的经济效益,值得推广。[Objective]The aim of this study was to explore the effectiveness of crossbreeding Simmental and Angus cattle in improving local yellow cattle.[Methods]Simmental and Angus cattle were used as the terminal male parents of beef cattle to conduct binary economic hybridization with local yellow cattle.Statistical analysis and research were conducted on the weight change and slaughter performance data of hybrid F1.[Results]The results showed that both hybrid F1 had faster growth speed and higher meat production rate than local yellow cattle,which could effectively improve the slaughter performance of local yellow cattle.[Conclusions]This indicates that the crossbreeding advantage of improving local yellow cattle with Simmental and Angus cattle is significant,which can effectively increase the economic benefits of local yellow cattle breeding and is worth promoting.
