摘要
本文通过对隆林山羊周岁体重和体尺指标的相关性分析,不仅为隆林山羊生长发育模型的构建起基础作用,同时也为山羊的选种选育提供重要参考依据。试验选取150只(公羊占20%)12月龄的隆林山羊测量体重、体高、体长、胸围和管围五个生长性状指标。通过SPSS软件对隆林山羊的体重和体尺指标进行相关性分析与通径分析,建立最优回归方程。结果表明,隆林山羊周岁的体重(Y)与体高(X_1)、体长(X_2)、胸围(X_3)、管围(X_4)成极显著正相关(P<0.01);与体重的相关系数以体高最大(0.748),其次是体长(0.653)和胸围(0.610),管围与体重的相关性最小(0.224);得到最优回归方程:Y=0.412X1+0.192X2+0.173X3-16.912。
This article aims at the study of the correlation between yearling weight and body size indexes in Longlin goat, to build Longlin goat model of growth and development, and also provide the theoretical evidence for the breeding and conservation strategies. The experiment select- ed 150 one year old Longlin goats（Ram 20%） measuring their body weight, body height, body length, cannon circumference and heart girth five indicators of growth traits. Body weight and body size indexes correlation analysis and path analysis were analyzed by SPSS software, and the optimal regression equation is established. The results showed that the body weight（Y） with the body height（X1）, the body length（X2）, the heart girth（X3） and the cannon circumference（X4） were significantly positive correlations（P〈0.01）. The correlation of the body weigh, the body height were maximum（0.748）, the body length（0.653）, the heart girth（0.610） were the second, the cannon circumference were minimum（0.224）.The most superior regression equation was Y=0.412X1＋0.192X2＋0.173X3-16.912.
