The wool quality in terms of staple length (cm), fibre diameter ([micro]m) and total medullation (%) was found to be comparable in lambs irrespective of dietary treatments (Table 4).
The CT supplementation in the present study had no significant effect on wool quality in terms of staple length (cm), fibre diameter (gm) and total medullation (%) similar to the earlier reports [2], however, contrary to some reports describing beneficial effect of CT on these parameters in grazing sheep [23,42].

In manual microscopic methods we determined the medullary pattern, hair width and medulla width to identify the prey species in scats, while average fiber diameter, diameter distribution and percent medullation was measured by OFDA.

After manual microscopic analyses, the hair fiber diameter as well as medullation (MD) in fibers was measured using latest computer aided OFDA.
These hairs are characterized by decreased pigment near the root, lack of medullation near the root, and increased cortical fusi near the root (Petraco 1988).
British breeds have coarse fleeces similar to that of Iranian sheep breeds in terms of fibre diameter, overall level of medullation and fleece structure.
The coarseness and fleece structure of Iranian carpet wool breeds is not due to primary follicle density but rather secondary follicle density which in turn causes lower fibre diameter, decreased level of medullation or variability in the fibre length and diameter within the staple.
