Abstract
The histomorphological study was made on the skin biopsies from left mid-side region of Gir cattle (Bos indicus), to investigate the age differences in skin structure of twelve young and twelve adult animals as well as the regional differences in twelve different regions of six adult cadaver. The vertical and horizontal sections were taken on cryostat microtome and stained with H & E stain for micrometry, Hart's stain for elastic fibres, Ferrlc-Ferricyanlde stain for melanin pigmentation and Alcian blue (pH 2.5) and PAS stain for mucopolysaccharides. The study was made on epidermis and dermis, various structural characteristics of sweat glands and hair follicles as well as the distribution of melanin pigment, elastic fibres and mucopolysaccharides, giving more emphasis on thermoregulatory structures. The mean total thickness of fresh skin biopsy snippets from mid-side region was significantly higher in adult animals (4.49 ± 0.37 mm) than that of the young animals (2.78 ± 0.20 mm).
