Abstract

Abstract: By measuring the wool diameter, breaking strength, curl number, and wool length of 6-month-old Tan sheep, the differences and correlations in wool traits in different parts （shoulders, abdomen, hind legs, buttocks） of 6-month-old Tan sheep were explored. The results showed that there were no significant differences in the straight length, natural length, breaking strength, wool diameter, and curl number of wool in different parts of the 6-month-old Tan sheep; the uniformity of the length of wool in various parts was good, and the trend of the straight length of wool was basically consistent with the natural length, indicating a certain correlation between the two;the coefficient of variation of the diameter of heterotypical fibers and unmyelinated wool was 6.21%~8.02%, indicating that the diameter of wool was relatively stable;the breaking strength of the heterotypical fibers was significantly greater than that of unmyelinated fibers, indicating a strong correlation between wool diameter and breaking strength;the curls number of unmyelinated wool in the abdomen, hind legs, shoulders, and buttocks was greater than that of heterotypical fibers, indicating that a smaller diameter of wool was beneficial for curling;the correlation analysis of various traits of abdominal wool in 6-month-old Tan sheep showed that the correlation coefficients between unmyelinated fibers traits were mostly larger than those between the heterotypical fibers. This might be due to the longer length of the heterotypical fibers, which was easily influenced by nutrition and external factors.

Key words: 6-month-old Tan sheep, different parts, wool, traits, unmyelinated wool, heterotypical fibers
