摘要
[目的]为了进一步了解新疆褐牛的生产性能,找到合理的新疆褐牛经济价值的估算方法。[方法]我们在塔城和昭苏选择了102头在放牧状态下饲养的新疆褐牛进行屠宰测定,对反映产肉性能的主要性状进行了统计分析,[结果]表明:体高、体长、胸围、管围与屠宰重、胴体重的相关极显著(P<0.01),并根据统计结果建立了体尺与胴体重的回归方程。[结论]经过验证,新疆褐牛胴体重与体尺存在着极显著的四元线性回归关系,所得回归方程真实有效。
【Objective】The objective was to further comprehend the production performance of and to find the reasonable evaluation method on economic value of Xinjiang Brown cattle.【Method】102 grazing Xinjiang Brown cattle from Tacheng and Zhaosu were determined,and the main traits reflecting meat performance were analyzed,【Result】The results showed that the association between body height,body length,chest circumference,circumference of cannon bone and live weight,carcass weight was extremely significant（P0.01）.A regressive equation of body size and carcass weight was established according the statistical results.【Conclusion】By the verification,there was significant linear relation with four factors between carcass weight and body ruler,the regressive equation was real and availabe.
