摘要
Abstract
In the process of establishing the identification standard of Xinjiang brown cattle 9th point system,569 Xinjiang brown cattle adult cattle in three cattle farms:Xinyuan County,Nileke County and Zhaoxu County of Yili Prefecture were measured and 13 body size traits correlation and principal component analysis was carried out.The results showed that the body weight of Xinjiang brown cattle had a significant correlation with body height,body length,chest circumference,abdomen,rump width,rump length,hind leg width,hind leg thickness and hind legs (P ＜0.01);13 The contribution of the first principal component in the principal component is the largest,which reflects the overall structure of the Xinjiang brown cattle,and the second and third principal components reflect the hindquarters and the rump characteristics.关键词
