Summary

In the flight experiment investigating the postembryonic development of Japanese quail chicks under conditions of microgravity, new knowledge has been obtained.
After the incubation of quail eggs, which had passed 13-14 days of their embryonic development on Earth, 64.3 % hatchability was achieved, and no anomalies of embryos were found.
Besides microgravity the quails were also observed under conditions of artificial gravity. The centrifuge of 0.5 m diameter proved to be unsuitable for influencing the early postembryonic development of Japanese quail chicks and their adaptation to space flight.
For the first time, living quail chicks, hatched in space, returned to the Earth.

Key words: Japanese quail chicks; ontogenesis; microgravity
