摘　　要：通过在昭苏县测定的1 338头不同年龄新疆褐牛放牧条件下体尺体重等资料进行统计,分析了新疆褐牛年龄、胎次与体尺、体重之间的关系和放牧条件下新疆褐牛生长规律,为有计划的开展育种工作和提高褐牛的终生生产性能提供科学依据。结果表明:新疆褐牛年龄和胎次对体尺、体重有显着的影响。综合分析认为新疆褐牛在相同的饲养管理条件下2岁以前生长发育迅速,是牛生长发育最重要的时期,到2岁时平均体重可达成年(按4岁为成年)牛体重的80%以上,体高、体长等主要体尺指标可达成年牛的90%以上。The relationships between the age,parity, body size and body weight of Xinjiang brown cattle were analyzed based on the data of body size, body weight collected from 1 338 Xinjiang brown cattle with different age under grazing condition in Zhaosu county. All of this were expected to provide scientific basis for developing breeding work in a planned way and improving brown cattle＇s long- term production performance. Result showed that age and parity have significant effect on body size and body weight. Comprehensive analysis showed that the development of Xinjiang brown cattle under 2 years old is rapid at the same breeding and management, it is the most crucial time for Xinjiang brown cattle. At age 2, average body weight may be up to more than 80% of adult cattle （4 years old taken as adult cattle） , main traits such as body height and body length may reach more than 90% of adult cattle.
