摘要: [目的] 核心牛群是奶牛育种体系的核心种质资源,其繁育管理水平直接影响遗传改良进程与牧场效益。然而,生产实践中,核心牛群管理仍存在若干认知与操作层面的误区,制约着遗传潜力的发挥。本文旨在系统剖析上述误区的生物学与遗传学机理,并提出针对性改进建议。[方法] 通过系统检索PubMed、CNKI等数据库中2011—2026年发表的奶牛繁育管理相关文献,并结合牧场生产实践,对核心牛群繁育管理中的五大常见误区进行梳理与分析。[结果] 五大误区分别为:过度依赖产奶量作为选择标准、忽视基因组选择与表型数据整合、营养管理滞后于繁殖调控需求、忽略子宫健康与胚胎移植衔接管理、数据记录缺乏长期连续性。针对各误区,分别从构建综合选择指数、建立基因组与表型双重筛选流程、实施分阶段精准营养方案、建立受体牛量化筛选体系、推进电子化数据管理等方面提出改进方案。[结论] 核心牛群管理须从经验驱动转向数据驱动,由单一性状选择转向多性状协同优化,方能实现遗传潜力与经济效益的同步提升。
