| This study was carried out at Grdarashah field/ college of Agriculture – Univ. of Salahaddin-Erbil. In two periods, the first period in mid October year 2005 to include both spring and summer seasons and the second period from mid April year 2006 to include both autumn and winter seasons. The samples were taken from mid-side for (59) ewes in various ages. Means of both first and second period of each of staple length (8.71 and 5.76 cm) respectively, fiber length (10.17 and 8.79 cm) respectively, clean wool growth (0.17 and 0.11 mg/ cm2/ day) respectively, raw wool growth (0.32 and 0.32 mg/ cm2/ day) respectively and clean wool percentage (59.90 and 41.23)% respectively. The significant effect (P≤0.01) of ewe's age appeared on all characteristics except raw wool growth in the second period and clean wool percentage in both periods . Also the effect of ewes status (barren and born) has significant effect (P≤0.01) on staple length, raw wool growth and clean wool percentage in both periods and significant effect (P≤0.05) on raw wool growth in the first period. The effect of sex of lambs born was non-significant on all studied characteristics. It was found that ewes in the same status had significant effect (P≤0.01) on all characteristics in both period except raw wool growth .It was found that ewes in the first period were significantly higher than second period in all characteristics. The barren ewes were significantly higher in all characteristics than born ewes while no significant effect appeared between born ewes (male born ewes and female born ewes). | ||
