Abstract
One of the interior features that characterize the constitutional type, condition and productivity of an animal is the skin. The skin differs from the internal organs in that its study is possible without slaughtering an animal. The identification of biological reserves of the body of meat breeds of sheep and their use in order to increase meat and wool productivity and improve its quality is also of not only theoretical, but also of great practical interest. In this regard, for a deeper understanding of the essence of the problem, the creation of scientifically sound breeding methods, it was necessary to study the morphological features of the skin cover of meat breeds of sheep of domestic and imported origin, as an important and very multi-functional organ. Skin studies have revealed the features of the growth and development of hair follicles during the ontogenesis of sheep, to establish patterns of formation of the skin and wool cover of sheep of different meat breeds. It has been established that the development of the skin and wool cover in sheep of different breeds occurs differently, each breed of sheep, even in one direction of productivity, differs only in its inherent, characteristic features
