Abstract
In this paper, the correlation coefficients among the various economic characters of the Inner Mongolia white cashmere goats such as cashmere yield (Y) , bo dy weight (X1), cashmere thickness (X2), staple length (X3), cashmere fineness (X4) and cashmere stretched length(X5) are analyzed with the SAS8.1 software, and the regression equation between the cashmere yield and other economic characters is established based on the path analysis. The results shows that the main factor determining the cashmere yield of rams is the body weight and that of ewes is the cashmere thickness of the cashmere, followed by the body weight. The regression equations of rams and ewes between the cashmere yield and other economic characters were Y=7.0462X1+15.6568X2-7.2930X3+14.5744X5 and Y=176.8148+5.0321X1+45.5121X2-3.4524X3+15.6498X4+18.7189X5, respectively. It’s recommended to put emphasis on the body weight and cashmere yield and give dual attention to the cashmere thickness and cashmere fineness when breedin g the Inner Mongolia white cashmere goats, in order to obtain good breedin g effect.
