The intensity of sheep’ muscle growth is divided into three groups: slow-growing, moderately growing and rapidly growing; weight and size of muscle fibers depends on functional activity. At the same time, the literature does not sufficiently cover the issues of weight growth of muscles and separate muscles. To achieve this goal, the carcasses obtained for dissection were carefully removed from the irrigation fat, then the muscles on the left side of each carcass were dissected. Each muscle was released from fat and then weighed with its tendons. In the process of dissection the muscles were divided in accordance with the biological division of muscles of the axial and peripheral parts of the skeleton. As for the muscles of the axial skeleton, the longest, widest, thoracic surface, thoracic deep muscles and the rest of the axial skeleton musculature were studied. The peripheral part of muscles was divided into the muscles of the thoracic limb (double-headed, three-headed, abutment, radial, patella, finger flexors and extensors and the rest of the thoracic limb musculature) and pelvic limbs (tensor fascia of the thigh, double-headed, gluteus, semi-tendinous, semi-membranous paliperidonesee, quadriceps, adductor, triceps tibia, fibula, finger flexors and extensors and the rest muscles of the pelvic limbs). The analysis of the materials at the time of lambs’ birth showed that the degree of limb muscles development (to the weight of adults) was higher (12.11%) than the muscles of the trunk (10.57%). After birth, the muscles of the body increases more vigorously (growth coef. 9,460) than the muscles of the limbs (growth coef. 8,260), as a result, the degree of development at the age of 13 months was higher in the first (89,96 %) than in the second (86,17%). The relative muscle mass of the axial skeleton increases on average by the age of 13 months and reaches to a maximum 61.99 % of the total muscle mass, while the muscles of the peripheral part decreases and reaches a minimum with 38.01% by this age. Key words: musculature, two-headed, three-headed, abutment, radium, scapula, finger flexors and extensors and the rest of the musculature of the thoracic limb
