Introduction. 
The formation and development of the organism take place under the direct influence of the 
internal and external environment, in which the factors that have an inadequate influence play a 
particularly important role. Under the influence of these natural conditions, the morphogenesis of the 
motor organs and the dynamics of changes in their linear dimensions and absolute weights at different 
physiological stages of postnatal ontogeny are of great scientific and practical importance. 
According to IVKhrustaleva et al., The skeletal muscular system is a more active part of the 
musculoskeletal system, consisting mainly of auxiliary elements such as muscles and fascia, joints, and 
attached to the skeleton as a skeletal system or causing various body movements or skeletal stiffness 
holds it in a certain position [6]. 
The researchers [1, 9] observed that the muscle tissue of cattle, sheep, and pigs consisted of 300 
anatomically separate muscles. 
Muscles, as a whole, are made up of transverse muscle tissue, the structural elements of which 
are fiber. According to the authors, they are elongated, ranging in thickness from 1 μm to 150 μm, and 
in length from 20 μm to 34 cm, and the diameter of the muscle fiber depends on the animal's type, age, 
sex, and other factors. 
The Dorper breed of meat-oriented sheep has undergone acclimatization and adaptation to care 
in the conditions of livestock complexes and farms of the Russian Federation, it is fast-growing and has 
a live weight of 12 months at birth compared to newborn lambs. an average increase of 28.59 times was 
found [4]. 
Histological analysis of the muscle tissue of the first and second-generation rams, which are 
characterized by rapid maturation and high meat quality, [2] showed that the thinnest fibers were 
observed in the second-generation rams. 
The most rapid growth of meat-and-fat lambs occurs from birth to 4-4.5 months. Genetic 
features during postnatal ontogeny formed during the evolution of sheep of the Edilbaev breed. , as well 
as the high milk yield of ewes and their good adaptability to the natural conditions of the breeding areas 
[5]. 
According to J. Wegner et al. [10], the correlation between the number of muscle fibers and the 
total weight of the muscle can be seen in the example of “two
-
muscular” breeds of large 
horned cattle, 
because they were found to have almost twice as many muscle fibers as those of other breeds. 
Other authors report that genomodified rams weighing 69 kg had a 40% greater shoulder muscle 
mass than normal animals, but that the taste of the meat deteriorated [7, 8].
