TLDR Goat skin has collagen, elastic, and reticular fibers, with hair follicles increasing in depth as goats age.
The study examined the histomorphological, histochemical, and histoenzymic characteristics of goat skin, using 220 samples from various body regions of goats aged 6-12 months (Group I) and over 1 year (Group II). The dermis was found to consist of collagen, elastic, and reticular fibers, connective tissue cells, blood vessels, nerves, hair follicles, sweat and sebaceous glands, and arrector pili muscles. The dermis was divided into a thin papillary layer and a thick reticular layer, with collagen fibers being the most abundant. Hair follicles were more numerous in the papillary layer, and their depth increased with age. Histochemical analysis showed moderate PAS activity in the papillary layer and moderate Sudan black B activity in the reticular layer. Enzymatic activity included mild acid phosphatase in both layers and moderate activity in blood vessels, with mild alkaline phosphatase activity in both age groups. This research provided baseline data for future studies on goat skin.
