In order to meet the demands of experimental minipigs for biomedical researches, we have aimed at cultivating grazing Chinese Wuzhishan (WZS) minipigs and trying to make them useful and affordable since the 1990s. After more than ten years of captive cultivation following sound management practices and a rigorous selection program for fertility and litter size, we established an outbred WZS minipigs colony with a core group (14 males and 30 females) and an expanding group (20 males and 40 females). In 2010-2013 periods, extensive background data of this colony were recorded and analyzed. This paper was written to provide pertinent information about outbred WZS minipigs for producers, users, and others concerned with WZS minipigs. It contains physical characteristics, growth performance, productive performance, hematology and blood biochemistry, microsatellite analysis, organ coefficients, and carcass properties. Results show that WZS minipigs have characteristics of small body size, slow growth rate, long life cycle, high reproductive rate, and maintaining original genetic diversity. All data present that outbred WZS minipigs are suitable laboratory animal and model animal.
为满足生物医学研究对实验用小型猪的需求,自20世纪90年代以来,我们致力于培育放牧型中国五指山(WZS)小型猪,并使其兼具实用性和经济性。经过十多年遵循良好管理规范以及针对繁殖力和产仔数的严格选育计划的圈养培育,我们建立了一个封闭群WZS小型猪群体,包括一个核心群(14头雄性和30头雌性)和一个扩展群(20头雄性和40头雌性)。在2010 - 2013年期间,记录并分析了该群体的大量背景数据。撰写本文旨在为养殖者、使用者以及其他关注WZS小型猪的人士提供有关封闭群WZS小型猪的相关信息。它涵盖了体貌特征、生长性能、生产性能、血液学和血液生化、微卫星分析、器官系数以及胴体特性。结果表明,WZS小型猪具有体型小、生长速度慢、生命周期长、繁殖率高以及保持原始遗传多样性的特点。所有数据表明,封闭群WZS小型猪是合适的实验动物和模式动物。
