The aim of this study was to comparative the histological structure of skin in Jenubi cow and its Friesians crossbreed cow. Samples of skin were collected from abdominal regions of Jenubi cow and its Friesians crossbreed cow immediately after slaughter in Governorate of Misan. The results showed similarities in the structure of the normal skin layers which was consists of three layers epidermis, dermis and hypodermis. Sweet glands was more distributed in the region between papillary and reticular layer and are associated with hair follicles. The primary hair follicle was associated with Sebaceous glands which were scattered in the deeper part of the reticular layer in both Jenubi and cross breed skin. The deference’s found in the micrometrical observations in the dermal layer, these variations between breeds in epithelium thickness of sweet glands where small in Jenubi cow while the epithelium thickness of crossbreed cow was more greater. The present study it was revealed that the sweat gland diameter in the skin of Jenubi cow was lower than in crossbreed cow. The conclusion of this study revealed that the location of the papillary layer is superficial and just under the basement membrane while the reticular layer composed the deeper layer in the dermis. The type of sebaceous gland was a simple, branched or compound. The epithelium thickness of sweet glands in crossbreed cow was more greater than Jenubi cow.
