摘　　要：为更好了解斜卡黄牛生产性能情况,笔者对200头斜卡黄牛体型外貌进行了调查,并测定了不同性别、不同年龄阶段共计120头斜卡黄牛的体尺(体高、体斜长、胸围和管围)和体重,绘制了斜卡黄牛生长发育曲线,计算了斜卡黄牛的肉用指数。结果表明,斜卡黄牛有较好的体型体况,周岁以前是斜卡黄牛的生长发育高峰;斜卡黄牛BPI指数值相对偏低。提高肉用性能是未来斜卡黄牛选育和改良的一个方向。The author investigated exterior appearance of 200 Xieka cattle,measured the body size(body height,body length,chest circumference and tube circumference)and weight of 120 Xieka cattle of different sexes and ages,drew the growth and development curve,calculated beef performance index of Xieka cattle,in order to better understand the production performance of Xieka cattle.The results showed that Xieka yellow cattle had better body condition,the growth and development peak of Xieka cattle was before one year old.The BPI of Xieka cattle is relatively low,improving meat performance is a direction of breeding and improvement of Xieka cattle in the future.
