| Abstract This study was conducted at Animal Resources Department College of Agriculture and Forestry at Mosul University on two randomized groups of Awassi and Hamdani ewes by 32 ewes group. The study started at 1562009 for a complete productive season to follow-up wool fibers growth with blood samples withdrawn by 3 months intervals. The results revealed a significant effect (p≤ 0.05) for age on staple length (SL), a significant effect (p≤ 0.05) for physiological status of ewes on fiber length (FL), and a highly significant effect (p≤ 0.01) for production stage on all wool traits studied. There was a significant effect (p≤ 0.05) for breed on cholesterol and ALT enzyme, a highly significant effect (p≤ 0.01) for breed on sugar, total protein (TP) and AST enzyme. There was no significant effects for ewes age and their physiological status on all blood components. There was a significant effect (p≤ 0.05) for productive stage on hemoglobin and cholesterol, , a highly a significant effect (p≤ 0.01) on sugar, (TP) and AST enzyme, with no significant effect on ALT enzyme. There was a significant phenotypic correlation (p≤ 0.05) between (SL) and (TP) 0.13, a highly significant correlation (p≤ 0.01) between both (FL), fiber diameter (FD) with (TP) 0.19 and 0.19 respectively, and a highly significant correlation between both (FL), (FD) with hemoglobin 0.22 and 0.28 respectively. While the rest of the relationships were non significant. | ||
