| Abstract | ||||
| This study was carried out on three flocks of Barki sheep raised at three different geographic locations in the region namely; Sidi-Barani, Dabaa and experimental farm of Alexandria University. Number of ewes in each location studied were 50, 45 and 56, respectively. Ewes in each location were classified into two groups based on head colour. The wool traits and skin follicles were studied. The results showed significant differences in wool growth, YLD%, STL, CR, FD, BUL, SS and EL% due to location. Barki sheep located at Sidi Barani gave more bulkiness, finer wool and shorter staples than those located at Dabaa and Alexandria farm. The head colour did not have any significant role in determining the wool traits and wool follicle characteristics in the skin of Barki sheep. Thus the head colour of Barki sheep could not be used as a marker to improve its wool traits. Differences among management in all wool traits studied except bulkiness were found to be highly significant. The influences of location and management on fibre type ratio and medullation index were significant. Variations in number of follicle group /cm2 and number of primary follicles in the skin due to origin and age of animal were highly significant, while those due to head colour were not significant . Origin , age and head colour had highly significant effect upon secondary follicle and S/P ratio . From the present results it might be concluded that sheep flocks located at Sidi Barani gave fine fibres thus such flocks are preferable for apparel product , while the fleeces of Barki located at Dabaa are preferable for carpet . | ||||
