摘要
科学合理的场内种猪育种方案是整个育种工作的纲领性文件,对企业种猪育种持续有效实施具有至关重要的作用。我国多数种猪场对此缺乏足够的认识,难以针对本场特有的种猪群体制订合适的个性化育种方案,从而影响到企业育种工作的顺利开展。本文从繁育体系构建角度,以企业种猪群体的遗传背景和目标市场分析为基础,探讨育种目标确定、遗传参数估计、育种核心群组建、选种方案制订等育种方案设计的主要环节。结合华南区部分核心育种场的实际育种方案执行案例分析,讨论个性化育种方案制订的原则和方法。建议育种方案制订应适应猪育种目标多元化发展需要,准确分析目标性状的经济价值,合理分配有限的育种投入,并高度重视种猪数字化育种体系的建设。
Scientific and rational pig breeding scheme within-herd is the programmatic document for whole breeding implementation, and is urgent for persistent breeding. However, the most pig breeding farms paid little attention to it, therefore it was difficult to design a rational breeding scheme for the specific nucleus herds, and finally the breeding works on-farm was inefficient. In this paper, for the pyramid breeding system, based on analysis genetic background of nucleus herds and requirement of targeting market for pig farms, it was discussed for breeding scheme design that breeding goal, estimation of genetic parameters, construction of nucleus breeding herds, and selection program. After analysis of practical scheme in some nuclear breeding farms in south China, it was discussed that the principal and method for design individualization breeding scheme. It was recommended that the scheme should adapt to the diversification of breeding target, accurate analysis of economic value for selection traits, reasonable distribution of limited breeding investment, and pay high attention to construction of digitize management system for pig breeding.
