摘　　要：我国肉牛种质资源长期面临进口依赖性强、国内优质种牛缺失、肉牛育种企业利润低、管理效率低、区域联合育种效果不理想等问题,全面了解认识我国肉牛当前育种技术、扩繁培育技术、推广体系模式现状是解决问题的前提。本文综述了国内外肉牛遗传性状评定标准与关键技术,肉牛联合育种中的育繁推一体化模式,针对国内外肉牛育种、扩繁培育、推广模式中关键技术的现状进行对比研究,分析了我国肉牛育种当前存在的现状与问题,并在信息化技术应用、引进肉牛品种的利用、本土肉牛的培育等方面提出建议,旨在有效推动我国肉牛“育种、扩繁、推广”一体化进程,加快本土肉牛品种培育,提升我国肉牛联合育种水平。The germplasm resources of beef cattle in China have chronic problems,such as heavy import dependence,lack of domestic high-quality breeding cattle,low profits of beef cattle breeding enterprises,low management efficiency,and unsatisfactory regional joint breeding results.The first and essential solution is to comprehensively understand the current status of beef cattle breeding technology,multiplication and cultivation technology and promotion system model.The paper summarizes the evaluation standards and critical technologies of domestic and foreign beef cattle genetic traits and the integrated model of breeding,propagation and promotion in joint breeding for beef cattle.We also present the current status and problems of beef cattle breeding in China.At last,we put forward suggestions on the application of information technology,the utilization of imported beef cattle breeds,and the cultivation of local beef cattle,aiming at accelerating the cultivation of local beef cattle breeds and improving the joint breeding level of beef cattle in my country.
