摘要: 为研究内蒙古二郎山绒山羊体尺、绒毛性状与经济性状间的相关关系,选取1 000只3岁成年母羊进行生产性能测定,并利用SAS 9.0和Excel 2003软件进行统计分析。结果表明,二郎山绒山羊体尺、绒毛性状中体高(X1)、体斜长(X2)、胸围(X3)与体重(Y)之间呈极显著正相关(P<0.01),最优回归方程为Y=-12.0856+0.0821X1+0.4053X2+0.1624X3,回归方程的截距和3个偏回归系数都达到了极显著的程度(P<0.01),说明该方程是最优回归方程。胸围对体重的影响最大,而体高、体斜长和绒细度主要通过胸围对体重产生影响;体高对产绒量的影响最大,其次为绒厚度,但是就体高、体斜长、胸围、绒细度、绒厚度、毛长与产绒量之间并未找到最优回归方程。表明二郎山绒山羊体尺、绒毛性状与经济性状之间存在着复杂的内在联系。

Abstract: To study the correlation and regression analysis of body size, cashmere traits and economic traits in Inner Mongolia Erlangshan cashmere goat, we selected the 1 000 3-year-old ewe and carried out production performance measurement, and using SAS 9.0 and Excel 2003 softwares for statistical analysis.The results indicated that a significant positive correlation of body height(X1), body length(X2), heart girth(X3) and weight(Y)in Erlangshan goat.Regression model was Y=-12.0856+0.0821X1+0.4053X2+0.1624X3.The intercept and three partial regression coefficient had reached a very significant extent (P<0.01), and indicating the equation was the optimal regression equation.The heart girth was the biggest influence on body weight, and the body height, body length and cashmere fineness impacted on body weight through the heart girth.The body height was biggest influence on cashmere yield and cashmere thickness for the second.We did not find optimal regression model between body height, body length, heart girth, cashmere fineness, cashmere thickness, hair long and cashmere yield.These results indicated the presence of complex intrinsic link between body size, cashmere traits and economic traits in Erlangshan cashmere goat.
