Correlation Analysis and Establishment of Regression Model between Body Weight and Body Size Traits of Cows of Weining Cattle
In order to study the effect between body weight and body size traits of cows of Weining cattle,The SAS 9.0 software was used to conduct correlation analysis and multiple linear regression analysis on the body weight and body size traits of adult cows of Weining cattle,and a regression equation was established.The results showed that:(1)There was a highly significant positive correlation(P＜0.01)between the body weight(Y)of cows of Weining cattle and six body size traits,which including body height(X,),body length(X2),height at hip cross(X3),chest circumference(X4),abdominal circumference(X5),and circumference of cannon bPone(X6).A-mong them,chest circumference had the maximum effect for body weight,followed by abdominal circumference,and the circumference of cannon bone was the least;(2)The regression equation is:y=-486.1576+1.2276x,+0.5526x2+0.9411x3+0.9726x4+1.4113x5+1.1862x6
