我国黄牛资源丰富,地方品种多达52个,具有耐粗饲、抗逆性强、肉质细嫩等优点,是全国各地肉牛生产的主体,但与国外引进肉牛品种相比还存在一些缺陷;加快黄牛肉肉用遗传改良,是发展我国现代肉牛产业的基础.针对国内许多地方在黄牛改良和肉牛生产过程中存在的认识误区和工作缺陷,文章在客观评价中国黄牛资源和肉牛引进品种的基础上,认为必须处理好保种选育与杂交改良的关系,不断强化技术创新和环节管理,加速肉牛遗传改良进程,并从明确改良计划和主攻目标、保护利用好本地牛种资源、做好选种选配和配合力测定工作、加强引进品种及其杂交后代选育等4个技术环节予以诠释.目前当务之急就是要正本清源,重点加强良种繁育体系建设。对从国外引进的肉牛品种逐一筛选梳理,对不符合种用要求的品种或个体要坚决淘汰。在引进国外优秀肉牛品种种公牛的同时,还要适当引进其优秀种母牛,以便能够自主培育种公牛。要全面开展肉用种公牛性能测定和后裔测定,以提高良种供种能力;同时,要加大对杂交后代优秀母牛的选留强度,良种、良法配套,为后续杂交改良提供优秀基础母牛,不断巩固遗传进展,努力增强肉牛产业发展后劲。
