摘要 核心群种公猪在繁育体系“金字塔”中最重要、地位最独特,但是大多数种猪场由于对现代种猪育种认识的局限和群体规模的限制,对种公猪的选育难以符合实际育种需要,成为制约我国种猪育种最主要的障碍。本文重点从种公猪育种目标、选择流程、种公猪培育与监控、遗传交流等方面,对核心群种公猪选择和培育进行系统分析。建议育种场根据自身育种目标制订合理的选择指数,严格坚持“先指数、后体型”原则,适当关注血统。打破狭隘封闭意识,实施区域性种公猪资源共享,提高选择强度,改进种公猪培育成功率,优化种公猪年龄结构,加快种公猪更替。利用数字化手段强化种公猪监控,提高主动淘汰比例,整体上提升种猪育种效率。 Nuclus boars are the most important and special functional group in modem pyramid pig production system, but selection and utilization of breeding boars are major obstruction and can not satisfy practical pig breeding requirement in China, due to the limitation of breeder understanding for pig breeding and scale of nuclus population. In this paper, the selection and breeding of boars was analyzed from the point of breeding goals, selection procedure, boars breeding monitor and genetic exchange. It was suggested that a rational selection index for breeding goals should be determined, the boars should be ranked with the index, the conformation could be used for secondary selection, and then the pedigree needed to be properly balanced. It is necessary to reform the closed parochial breeding idea for national pig breeding, the top boars shall be widely used cross breeding herds, so that selection intensity for boars can be increased. For boar utilization, it need to improve successful rate of boar raising, to decrease the age of used boars and to accelerate replacement of nuclus boars In order to improve pig breeding efficient for breeding farms, boar management should be digitalization and increased breeding culling
