| Abstract | ||
| Fleece traits have an economic importance in sheep, and they are influenced by fiber traits. The age of sheep and body region which samples are taken have an importance on the traits studied. The study involved 24 Awassi ewes aged 3 to 6 years at college of Agriculture region. To study the effect of age and samples taken from different regions of the body (Shoulders, Back and tail) on some physical and chemical wool traits greasy fleece weight, clean fleece weight, clean wool percentage, staple length, fiber length, crimps, wax percentage and determination of wool pH. Data were subjected to statistical analysis using General liner model (GLM), (SAS) program . The results revealed a significant (p ≤ 0.05) effect of age on staple length 11.694±0.536, 9.472±0.445, 10.083±0.480 and 10.227±0.503cm on for the ages 3, 4, 5, 6 years respectively. with no significant effects on other traits . There was a highly significant. (P ≤ 0.01) effect of shoulder region on crimps and wool pH 1.640±0.065, 1.581±0.079, 1.332±0.050 crimp / cm and 10.297±0.433, 9.417±0.120 , 10.145±0.55 respectively. | ||
