| Abstract: | The paper studies the relationship between the body size and production performance about Shanbei white cashmere goats, ascertains the linear relationship between the cashmere productive performance and weight, body length, body height, chest circumference and pipe. The correlation analysis, multiple linear regression, stepwise regression, and principal component analysis methods are adopted in the study, useing SPSS software data analysis functions, establishing the optimal regression model between body size and production performance, provideing good suggestions for breeding Shanbei white cashmere goat and improve the cashmere productive performance . |
