Abstract

This study determined greasy wool yield and selected wool-quality indicators of Mongolian sheep raised in Erdenedalai soum, Dundgovi Province, Mongolia, and compared the results with previously reported breed and regional data. The study was conducted in June 2025 using nucleus flocks from the Tsavchir, Tsagaan-Ovoo, Rashaan, and Sangiin Dalai baghs. Greasy wool yield was measured by control shearing in 177 animals, including 53 ewe lamb, 64 ewes, 30 ram lamb, and 30 rams. Mean greasy wool yields were 1.39 ± 0.015 kg, 1.76 ± 0.016 kg, 1.47 ± 0.034 kg, and 1.88 ± 0.052 kg in ewe lamb, ewes, ram lamb, and rams, respectively. Wool composition was analyzed in 22 sheep. Cashmere hair content ranged from 38.37 ± 4.80% to 47.13 ± 4.41%, intermediate hair from 3.90 ± 0.67% to 8.61 ± 3.23%, top hair from 16.58 ± 4.08% to 27.18 ± 5.92%, and coarse hair from 22.74 ± 1.83% to 34.57 ± 3.37%. Cashmere hair diameter was relatively uniform among groups, ranging from 22.30 ± 0.26 to 22.48 ± 0.67 µm, whereas coarse hair diameter reached 53.27 ± 0.86 µm in rams. Cashmere hair length ranged from 4.78 ± 0.08 to 5.99 ± 0.35 cm, and intermediate hair length ranged from 5.62 ± 0.32 to 6.79 ± 0.36 cm. Scurf and extraneous impurity levels were low. The results confirm that the studied Mongolian sheep population is a coarse-wool type and provide baseline information for wool grading, flock selection, and wool-processing practice.
