The aim of the study is to analyze the commodity properties of sheepskin and the histostructure of the skin of rams of Kalmyk fat tail breed and crossbreeds (1/2 Kalmyk fat tail × 1/2 Dorper). The uterus of group I was covered with sheep of the Kalmyk fat tail breed, and the ewes of group II with sheep of the Dorper breed (experimental group). The study revealed, the mass of paired sheepskins of young group I was greater than that of peers of group II by 1.0 kg or 34.5 % (P> 0.999). A large live weight affected the large area of the skin of the second group of young animals, and the length of the hair of the experimental group, which turned out to be shorter, affected the smaller weight of the sheepskin. Pets have the best quality indicators of sheepskin and the best histological structure of the skin. Cross-breed animals have 14.52 % of more elastic, stronger and less thick skin, due to a greater epidermis thickness of 27.7 % and a denser reticular layer of 13.7 %. Wool cover (the ratio of primary follicle on the secondary) in cross-breeding sheep is 10.47 % thicker, compared to peers of white color, which corresponds to the technological requirements for the production of high-quality sheepskins.
