The patterns and features of postembryonic skeletal muscle morphogenesis of females and males of the Japanese quail of egg flock, at different stages of growth (days 32 and 42), using the example of the musculus quadriceps femoris rectus capitis and superficial pectoral muscle including indicators such as: the thickness of muscle fibers and their bundles, the thickness of endomysium and perimision, the number of muscle fibers under the view, the correlation of muscle areas and the connective tissue on the longitudinal section. The work was carried out on the basis of the Department of «Anatomy and Histology of Animals» named after Professor A.F. Klimov and on the basis of JSC Technology Department of the Federal Scientific Center «VNITIP» RAS in the period from 2016 to 2019. Classical macro- and micromorphological methods and statistical analysis of the digital data obtained were used. Asynchronous growth of the skeletal muscles, increased differentiation of cellular structures at certain times (21st and 32nd days) has been established, differences in the histological structure of skeletal muscles depending on the age of birds and its gender has been shown. It was established that female quails of the breed studied dominate over males in all respects. A comparative characteristic of these muscles at different stages of postembryonic ontogenesis, as well as in regard to gendered dimorphism during research periods is given. Superiority of the quadriceps femoris muscle, namely its straight head over the superficial pectoral muscle, over all micromorphological indicators at all periods of the research, as well as the earlier differentiation of its intracellular structures.quailfemalemalemusclemuscular fiberproductivityперепеласамкасамецмышцыволокнапродуктивность[Афанасьев.
