【摘要】 为探究燕山绒山羊体尺、体重、绒厚与产绒量的相互关系,对燕山绒山羊各体尺指标、抓绒后体重、绒厚与产绒量进行相关分析、通径分析和回归分析,并建立最优回归方程。结果表明,体长（X₁）、体高（X₂）、胸围（X₃）、绒厚（X₅）、抓绒后体重（X₆）与产绒量（Y）均呈极显著正相关（P<0.01）,绒厚对产绒量的直接作用最大（0.547）,其次是胸围和体长（0.194和0.138）,抓绒后的体重主要是通过间接作用影响产绒量。燕山绒山羊体尺与产绒量的最优线性回归方程为Y=0.161X₁（体长）+0.244X₃（胸围）+0.555X₅（绒厚）。以上研究结果提示,对于燕山绒山羊的选育,在考虑提高产绒量的同时,需兼顾绒厚、胸围和体长等性状。更多还原

【Abstract】 To explore the correlation between body size, body weight, cashmere thickness and cashmere yield of Yanshan Cashmere Goat, the correlation, path and regression analysises between the body size, body weight after fleece, cashmere thickness and cashmere yield of Yanshan Cashmere Goat were conducted, and the optimal regression equation was established.The results showed that there were positive significant correlations between body length（X₁）, body high（X₂）, chest girth（X₃）, cashmere thickness（X₅）, body weight after fleece（X₆） and cashmere yield（Y）（P<0.01）. The direct effect of cashmere thickness on the amount of cashmere was the largest（0.547）, followed by chest girth and body length（0.194 and 0.138）. The body weight after fleece affected the amount of cashmere mainly through indirect effects. The optimal linear regression equation of body size and cashmere yield of Yanshan Cashmere Goats was Y = 0.161 X₁（body length） + 0.244 X₃（chest girth） + 0.555 X₅（cashmere thickness）. The above results suggested that for the breeding of Yanshan Cashmere Goat, it is necessary to take cashmere thickness, chest girth and body length into consideration when considering the increase of cashmere production.更多还原
