摘　　要：对祁连县高原型藏羊主要生产性能和生长发育情况进行测定分析,结果表明体重在初生～1岁增长最快,随年龄增加增长速度开始变缓,3.5岁龄后母羊体重停止增长,公羊3.5岁龄后仍在缓慢增长,而胸围的变化与体重保持了高度一致.在产毛量上无论公、母羊3.5岁时最大值,由于受放牧营养摄入量不足和繁殖行为影响,母羊生长发育缓慢,3.5岁龄体高和体长发育完成,而公羊则为2.5岁龄.The factors of growth development and main production performance of Plateau Tibetan sheep in Qilian county were examined. The results showed that the Plateau Tibetan sheep had a fastest growth between newborn and 1 year old. The growth becomes slow with age increasing. The ewes stop increasing body weight after 3.5 yeats old, but the rams can keep a slow growth of weigh4 and the change of chest circumference is keep highly consistency with body weight. The ewes and rams share maximum in wool production when they are 3.5 years rid. Due to the insutgicient nutrient intake under the grazing condition and effect of reproductive behavior, the ewes grow slowly. The body height and body length stop increasing when the ewes are 3.5 years old. It is different from the 2.5 years old of the rams.
