摘　　要：为了解影响中国美利奴羊(新疆型)母羊繁殖率的因素,提高细毛羊的繁殖率,对新疆巩乃斯种羊场,在不同饲养条件下的3群细毛羊的繁殖情况进行了跟踪调查。得到中国美利奴羊(新疆型)的配种体重适宜范围系数,提出标准体重的观点,用实际体重与标准体重的比值研究中国美利奴羊的膘情与生产性能之间的关系,发现该比值与中国美利奴羊(新疆型)次年产羔率有很强的相关性。In order to understand the factors of influencing ewe reproduction performance and to improve reproduction rate in Chinese Merino（Xinjiang type）,the reproduction information were investigated for 3 groups of fine-wool sheep under different raising conditions in Xinjiang Gongnaisi Fine-wool sheep Breeding Farm.The breeding liveweight coefficient of appropriate scope was obtained in Chinese Merino（Xinjiang type）,and the viewpoint of standard liveweight was presented.The ratio of the actual weight to standard weight was used to express the body condition of ewe in breeding season,and the relationship between the ratio and reproduction rate was analyzed.The result indicated that the ratio was significantly related to lambing ratio of ewe.
