EFFECT OF EARLY AND LATE CASTRATION ON ODOR GLANDS AND SKIN CHARACTERISTICS IN MALE BALADI GOATS
Skin samples of five body regions (parietal, shoulder, mid-side, coxal tuber and perianal ) were collected from nine male Baladi goats aged 16 months. The influences of body region and age of castration (early 2-week versus late 6– month of age ) on odor glands, hair follicles and epidermis were examined and tested. Skin from parietal region of kids exhibited significantly (P<0.05) the highest density of follicles ( 55.8 / mm2), among the other body regions. Whereas, parietal (1.7) and shoulder (1.5) regions were lower in S/P ratio than mid-side, coxal tuber (2.5 for each) and perianal ( 3, P<0.05 ) regions. Body region had a highly significant (P < 0.01) effect on density of sweat glands and sebaceous glands. The highest density of sweat glands was found in parietal region (14.8 / mm 2 ). Though the density of sebaceous glands in parietal region (26.0 / mm2) ranked the second after perianal region (36.6 / mm2), their size was larger in parietal region than in other body regions. Two-week castrated kids had significantly (P <0.05) less density of sweat glands than entire kids. However, the difference between entire kids and 6 – month castrates in sweat glands density was insignificant (P>0.05). As well, 2–week castrated kids had the lowest density of sebaceous glands compared with entire kids and 6 – month castrated ones. Histologically, the parietal glands of entire kids appeared highly modified and larger occupying the major part of the dermis with marked secretory activity than other regions as well as castrated kids. Sweat and sebaceous glands in parietal region of Baladi bucks are the major source of buck odor. Furthermore, the attained results revealed that castration of kids at an early age of life (2-weeks of age) plays an important role in reducing male odor.
