摘 要:[目的]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,[方法]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]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。[结论]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。[Objective] In order to objectively evaluate and study the growth and development characteristics of different production types and stages of Xinjiang brown cattle. [Method] Based on the membership function method in fuzzy mathematics, this article made a multi index comprehensive evaluation and comparative study on the data of important breeding indexes such as body size and body weight of Xinjiang brown cattle. [Result] The results showed that Xinjiang brown cattle with beef type had the characteristics and advantage of fast body measurements and weight growth;the mean values of membership functions corresponding to the 18-month age of brown beef type and the combined type were 0.73 and 0.34.And the main characteristic values were obviously differentiated. [Conclusion] 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.
