摘　　要：小型猪近交系是中国农业科学院北京畜牧兽医研究所以2头五指山猪(Sus scrofa)为系祖,历时15年,采用"近亲交配"、提高营养水平、同期发情以及笼架等饲养技术,逐步克服后代畸形率高、弱仔率高、成活率低等3大阶段性难题,育成国际上首个近交系猪。本文介绍小型猪近交系的培育过程、近交系研究鉴定、新遗传资源种质特性,以及开发利用。该研究成果填补了国内外近交系猪的研究空白,为大型哺乳近交系动物培育理论和应用研究提供了新的视角。Research results of miniature pig inbred cultivation and application, which were achieved by the scientists from Institute of Animal Sciences of Chinese Academy of Agricultural Sciences （CAAS）. By comprehensive measures of ＂inbreeding＂, improving the level of nutrition, estrus synchronization, and cage rearing technology et al., which lasted 15 years, they bred international＇s first inbred pigs with two Wuzhishan mini-pig（WZSP） （Sus scrofa） as progenitor, gradually overcame three stages problems as high offspring malformation rate, high weakling piglet rate and low survival rate. This article describes the breeding process, inbred line identification, germplasm characteristics of the new genetic resources, and their development and utilization et al. The results fill the gaps for pig inbred line in domestic and foreign research, and provide a new vision for animal inbreeding theory and applied research in large mammals inbred line.
