| 摘 要： | [目的]为了研究皮南牛生长发育状况，[方法]通过对河南新野县皮南牛某养殖场中的321头皮南牛成年母牛进行体尺性状测量，选择9个生长性状进行相关性和主成分分析。[结果]皮南牛体重与体高、体斜长、胸围、腹围、管围、十字部高、腰角宽、坐骨端宽具有极显著相关(P<0.01);从主成分的特征向量和贡献率来看，主成分一反映了皮南牛的整体外貌结构信息，第二主成分反映了尻部特征。

| Abstract: | In order to study the growth and development of Pinannan cattle, 321 adult Pinannan cattle were measured in a yellow cattle farm in Xinye County, Henan Province, and 8 traits of body weight and body size were selected for correlation and principal component analysis. The results showed as follows: the body weight of Pinan cattle was significantly correlated with the increase of body length, chest circumference, abdominal circumference, canal circumference, cross height and body length (P < 0.01); According to the eigenvector and contribution rate of principal component, principal component 1 reflected the overall appearance structure information of Pinan cattle, and the second principal component reflected the characteristics of Shiribe.This study provided the basis for clarifying the physique and appearance characteristics of Pinan cattle and breeding idea. |
