A comprehensive comparative microscopic and morphometric study of the superficial pectoral (SPM) and quadriceps femoral (QFM) muscles in hens and quails in the early stages after hatching was performed. In the muscles, diameter of the muscle fiber, area of the muscle tissue, representation of the muscle and connective tissue components were determined. A set of general regularities and specific features of postembryonic myogenesis of the studied structures in hens and quails has been established. The peculiarities of SPM and QFM ultrastructure in quails of the Manchzhurskaya zolotistaya (Manchurian gold) breed were revealed. Representatives of both studied groups of birds are characterized by an increase in the muscle tissue area, the diameter of muscle fibers and their bundles. The difference is a more significant development of the quadriceps femoris in hens, and the superficial pectoral muscle in quails. It was found that quails, unlike hens, had thickening of the endomysium and perimysium in both muscles.
