摘　　要：牛的体型与生产性能和健康水平密切相关,体型评定数据是牛群选配计划制定的重要参考资料。本研究以新疆地区5个规模化牛场的新疆褐牛19个实测性状的数据以及23个描述性状的评分记录为基础,分析不同饲养环境以及不同选育目标方向下新疆褐牛群体间的差异与各性状间的相关性。结果发现:不同生产方向新疆褐牛体型之间差异显著,乳用、肉用与兼用方向具有一定的选育基础;新疆褐牛体躯容量各性状之间呈正相关,乳房系统各性状之间均呈现高度的正相关;不同场之间乳房深度差异极显著且变异系数最大,1号场乳房深度的测量值与线性评定值均显著低于其他场。本研究结果为新疆褐牛9分制线性评定标准的制定以及新疆褐牛的选育工作提供了可靠的数据支撑。Cattle body type are closely related to production performance and health level.Body Conformation Linear Assessment is an important information for formulating selection plans.19 traits are measured and analyzed of Xinjiang brown cattle which from five large-scale cattle farms in Xinjiang.The results showed that there are significant differences between the body types of Xinjiang brown cattle in different production directions,and there is a breeding basis for dairy,meat and dualpurpose.There are positive correlations between body traits of Xinjiang brown cattle,and high correlations among breastrelated traits.The difference in breast depth between different fields is extremely significant(P<0.01)and the variation is the largest.The measurement value and Body Conformation Linear Assessmen value of breast depth in farm 1 are significantly lower than those in other farm.The improvement of this trait should be strengthened in the future.The analysis results of this study provide reliable data support for the establishment of the linear evaluation standard for the nine-point system of Xinjiang Brown Cattle and the breeding of Xinjiang Brown Cattle.
