Abstract

The article reflects the ultramicroscopic characteristics of the skeletal muscles of quails of the meat direction of productivity of the Pharaoh breed, on the 21st and 42nd days of postembryonic ontogenesis. The difference in energy exchange in muscles of different functional orientation is scientifically proved. Changes in the intracellular activity of skeletal muscles at different periods of postembryonic development are shown, which affects the growth rate and structural design of muscles. A comparative assessment of ultramicroscopic structures between two muscles (the superficial thoracic and quadriceps femora) of different functional orientation, in different periods of development, is presented.
