Correlation between body weight and body size of northern Shaanxi white cashmere goats
摘要
Abstract
[Objectives]Through The correlation between body weight and body size of northern Shaanxi white cashmere goats was studied and the optimal regression equation between body weight and body size was established to provide a scientific basis for the breeding of northern Shaanxi white cashmere goats.[Methods]713 northern Shaanxi white cashmere goats including 61 rams and 652 ewes from 80 northern Shaanxi white goat farms in Hengshan District,Yulin City,Shaanxi Province were used to measure the body weight and body size from March to May 2025.The regression equation was constructed with correlation analysis and path analysis.[Results]The body height,body length,chest circumference,chest depth,chest width,cannon circum-ference and recommended height of northern Shaanxi white cashmere goats were significantly positively corre-lated with the body weight(P＜0.01).The correlation between body height(X1)and body weight(Y)of rams was the highest(r=0.570),and the correlation between body length(X2)and body weight(Y)of ewes was the highest(r=0.509).The direct effect of ram body height(X1)on body weight was the largest(r=0.435),and the indirect effect of recommendation height(X7)on body weight was the largest(0.380),which was mainly through body height(X1).The chest circumference(X3)of ewes had the greatest direct effect on body weight(r=0.284),and the chest depth(X4)had the greatest indirect effect on body weight(0.199),mainly through the chest circumference(X3).The regression model of rams was Y=0.228X1+0.303X2+0.486X3(r=0.969,P＜0.01),and the regression model of ewes was Y=0.264X1+0.446X2+0.206X3+0.178X4(r=0.942,P＜0.01).[Conclu-sions]The body height of rams and the chest circumference of ewes mainly affected the body weight through direct effects,and the chest depth of rams and the body length of ewes mainly affected the body weight through indirect effects.The selection of body size including body height,chest circumference,chest depth and body length should be taken into account in the breeding and improvement of body weight of northern Shaanxi white cashmere goats.关键词
