Abstract:In this experiment,the length,fiber diameter,breaking strength and elongation of the villi on the side,back and scapula of Meiren yak were measured,the effects of different parts,sex,age and quality of villus were analyzed.The results showed that sex,age and body parts of Meiren yak affected the quality of villus,and the fiber diameter of female yak was significantly larger than that of male yak.There were significant differences in fiber diameter,natural length,straight length and breaking strength between male and female yaks at different ages,the quality indexes of villus of yak aged 3-6 years old were higher than those of yak aged 1-2 years old and relatively stable.The diameter and natural length of villus in the side of body were significantly lower than those in the back,and the breaking strength was significantly higher than that in the back.
