      摘要：为客观评价研究新疆褐牛不同生产类型各阶段的生长发育特征与特点，本文基于模糊数学中的隶属函数法对新疆褐牛的重要选育指标体尺、体重等数据进行多指标综合评价与对比研究，结果表明：新疆褐牛肉用类型具有体尺、体重生长发育快的特点和比较优势；新疆褐牛肉用类型与兼用类型18月龄阶段对应的隶属函数值均值为0.73和0.34，主要特征值分化明显；综合各阶段新疆褐牛体尺、体重和隶属值，在牧区开放式选育模式下新疆褐牛肉用类型生长发育快适宜性较好，各阶段中18月龄阶段表现最佳，适合作为新疆褐牛早期选育评价的重要节点。

英文摘要:

      For the research of xinjiang brown cow meat types at different stages of growth and development characteristics and the growth difference of different types, based on the method of membership function in fuzzy mathematics to xinjiang brown cow important breeding index body measurements to multi-index comprehensive evaluation, weight and other data, the results showed that the xinjiang beef with brown type has the characteristics of body measurements and weight growth fast and comparative advantage;The mean values of membership functions corresponding to the 18-month age of the brown beef type and the combined type in Xinjiang were 0.73 and 0.34, and the main characteristic values were obviously differentiated.Based on the body size, weight and subjection value of Xinjiang brown cattle at each stage, the brown beef type in Xinjiang showed better suitability for rapid growth and development under the open breeding mode in the pasturing area, and the 18-month age stage showed the best performance in each stage, which was suitable to be an important node in the early breeding evaluation of Xinjiang brown cattle.
