新疆绒山羊体尺、体重、毛长、绒长与产绒量的相关回归分析
Correlation Regression Analysis of Body Size,Body Weight,Wool Length,Cashmere Length and Cashmere Yield of Xinjiang Cashmere Goats
摘要
Abstract
In order to investigate the relationships between body measurements(body height,body length,chest circumference),body weight,hair length,cashmere length,and cashmere yield in Xinjiang cashmere goats,this study collected production data from 2039 adult female Xinjiang cashmere goats aged 1-5 years over a four-year period.Correlation,path,and multiple regression analyses were conducted,and an optimal regression equation was established.The results showed that body height,body length,chest circumference,body weight,hair length,and cashmere length were all significantly positively correlated with cashmere yield(P＜0.01).Stepwise regression analysis indicated that body weight had the greatest direct effect on cashmere yield,followed by body length,while chest circumference primarily exerted an indirect influence on cashmere yield.The optimal linear regression equation relating cashmere length(Xi),hair length(X2),body height(X3),body length(X4),chest circumference(X5),body weight(X6)to cashmere yield(Y)was:Y=13.918X1+7.325X2+4.512X3-9.541X4+8.689X5+228.063.This model pro-vides a scientific basis for predicting cashmere yield in Xinjiang cashmere goats and offers guidance for feeding management and genetic improvement in practical production.关键词
