Development and metabolism of chicken embryos in the embryogenesis under acoustic stimulation

Acoustic influence on the metabolic process in the last days of incubation of embryos of domestic chicken was found. It was shown that the changes that appear under the influence of acoustic signals lead to a decrease in incubation time. As a result of acoustic hyperstimulation, gaseous exchange and growth of the embryo continue to follow a power dependence characteristic of an earlier period of embryogenesis, i.e., the depression typical of these processes in the end of incubation is arrested. In acoustically stimulated embryos, a tendency toward a decrease in the total energy expenses on growth and metabolism is observed in the period from 17 days of incubation up to hatching, but the daily expenses on energetic exchange and growth are higher under acoustic influence than in the control group.
