ABSTRACT:
Twelve goats (six males, six females), four West African dwarf goats (WADG) and two red Sokoto goats (RSG) per group, were studied. The age ranged form 1 to 3 years. Skin samples were taken from the head area, caudomedial to the horns (horn glands), and from ten other areas of the body. Samples were fixed in formol calcium and alcohol. Thick free-hand sections were stained with Celestine blue and preserved in Canada balsam. Routine paraffin wax sections were stained with hematoxylin and eosin (H and E). The H and E stained sections were projected at a magnification of 200 X and sebaceous gland sections were traced on graph paper.Sebaceous glands in the horn glands showed significantly larger cross-sectional areas than sebaceous glands elsewhere in the body, but anatomically they were similar to them. Ducts of the sebaceous gland of horn glands usually open into hair follicles but a few ducts open on the surface. The cross-sectional area of sebaceous glands in the horn glands was significantly larger in males than in females and larger in WADG than in RSG.
