Correlation and Multiple Regression Analysis between Body Weight and Body Size Traits of Juvenile Forest Musk Deer
摘要
Abstract
In order to explore the correlation between body weight and body size traits of juvenile forest musk deer,un-derstand its growth and development and improve the breeding efficiency,105 juvenile forest musk deer(50 male and 55 female)cultured in Fengxian county,Shaanxi province were selected as the research objects.The body weight(Y),shoulder height(X1),hip height(X2)and body oblique length(X3)were measured.The correlation,path and multiple li-near regression analysis of each index were carried out and the optimal regression model was established.The results showed that the body weight,shoulder height and hip height of male juvenile musk deer were significantly higher than those of female juvenile musk deer(P<0.05);the body weight of male and female juvenile musk deer was significantly positively correlated with body oblique length(P<0.01),the body weight of male juvenile musk deer was significantly positively correlated with shoulder height and hip height(P<0.05),and the body weight of female juvenile musk deer was only significantly positively correlated with shoulder height(P<0.05);the most direct effect on the body weight of male and female juvenile musk deer was body oblique length,the most indirect effect on the body weight of male juve-nile musk deer was hip height,and female juvenile musk deer was shoulder height;the optimal regression models be-tween body weight and body size were Ymale=0.034X1+0.016X2+0.069X3-0.245(R2=0.187,P<0.05)and Yfemale=-0.024X1-0.002X2+0.166X3-1.574(R2=0.418,P<0.01).In conclusion,the body weight breeding of male juvenile musk deer should focus on the index of body oblique length and hip height,and the female juvenile musk deer should focus on the index of body oblique length and shoulder height.关键词
