ABSTRACT
In this study, SPSS17.0 software was used to analyze the wool fineness of 1079 Alxa Bactrian camels. The results showed that the wool fineness of male camel was significantly higher than that of female camel (P < 0.05). At the age of 2-7, the fluff fineness of male and female camel increased with age, At the age of 8-10 years, the fluff fineness of male and female camel has no obvious change trend with the increase of age. The best regression equation of male camel’s wool fineness to age is quadratic regression equation: Y=15.971+0.409X-0.008X2, the fitting degree is 0.983, the fitting effect is very good. The best regression equation of female camel’s wool fineness to age is also a quadratic regression equation: Y=15.597+0.564X-0.030X2, the fitting degree is 0.873, the fitting effect is better.
