摘要
以延边大学解剖教研室延边黄牛骨盆骨标本(3♂,3♀)为研究对象,应用常规解剖学方法对延边黄牛骨盆骨的40项指标进行测量,计算出14项测量指数.并将公牛和母牛的各项指标进行比较.发现公牛的骨盆入口中矢状径与骨盆入口横径比大于母牛,母牛的骨盆入口指数大于公牛,母牛的骨盆出口指数大于公牛.肉眼直接观察可见公牛的坐骨棘高度大于母牛.
Studied the specimens （3♂,3♀） of Yanbian Yellow Cattle pelvic bone in anato- my laboratory of Yanbian University, measured 40 indicatrix of Yanbian Yellow Cattle a- natomy pelvic bone with conventional methods, calculated 14 indexs. Then compared the indexs of bulls with that of cows. The results showed that the ratio of the arrowy diameter in bull＇s pelvic inlet transverse diameter and in the pelvic inlet was bigger than that of cows, pelvic entrance index of cows is greater than that of bulls, pelvic export index of cows is greater than that of bulls. Then found that the ischial spine of cows was higher than that of bulls by direct observation.
