The aim of study was to analyse the rearing of the Ross 308 parental stock in the context of hatching results. The study was carried out in production conditions. The body weight of birds was monitored using the JOTAFAN automatic weighing system during whole rearing and production period. Reproductive indicators were determined based on the results of eggs fertilization and hatchability. There was found that the body weight during rearing and production was in line with the standards for this breed. Moreover obtained reproductive indicators (fertilization of eggs and hatchability of fertilized eggs were higher than 90% between 28 and 56 week of parental stock life) indicate that environmental and nutritional conditions were proper.
