Abstract
The article presents a comparative analysis of the histogenesis of skeletal musculature of Smena-8
cross chickens and Pharaoh quails at different periods of postembryonic development. The regularities
and features of postembryonic histogenesis of skeletal muscles of chickens and quails are presented
on the example of the rectus head of the quadriceps femoris and the superficial pectoral muscle.
The periods of ontogenesis reflecting the formation of the muscular system in chickens and quails are
described. Increased differentiation of cellular structures at certain periods of development was established,
differences in the histological structure of skeletal muscles depending on the age of the bird and
its species were shown. A comparative characteristic of these muscles at different stages of postembryonic
ontogenesis is given. According to all micromorphological indicators, the superiority of the quadriceps
femoral muscle over the superficial pectoral muscle was established in all the studied periods, as
well as earlier differentiation of its intracellular structures, regardless of the species of chicken.
