abstract
Pig farming in India is still un-organized venture and about 70% of the pig population is reared under traditional system and Pigs are the chief converter of row feed into good source of human food. The pig shows anatomical and physiological similarities with human, which leads its role in biomedical research. The sweat glands has role in thermoregulation of the body. This study was conducted on twelve indigenous male i.e. six piglets up to two months of age and six adults above six months of age. The skin samples of various body regions were collected after slaughter of animals. The histological slides were prepared by the routine histological procedure of the tissue pieces of skin. The apocrine and eccrine types of sweat glands were observed in the reticular layer of the dermis. The eccrine sweat glands found only in snout region while apocrine was observed in rest of the body regions under study. The apocrine glands were saccular and convoluted tubular with longer and larger diameter than eccrine. The secretary units of apocrine glands were lined by cuboidal cells, while secretary units of eccrine glands were lined by clear and dark cells. The excretory ducts of apocrine glands opened at the base of the hair follicle, while that of eccrine glands opened through rete peg on the surface of skin. The secretory acini of both the type of glands were surrounded by spindle shaped myoepithelial cells. The values for the length, diameter and number of sweat gland were various in different body region and increased with advancement of the age of the animals. The average values for the micrometrical observations were higher in the dorsal abdominal region as compared with other body region in both the piglet and adult groups.
