摘要：This paper presents the results of a study of the paternal and maternal geese reproductive qualities, depending on their age. It has been established that in geese, regardless of their age, at the beginning of the biological cycle of egg-laying, the growth of all reproductive qualities occurs. In the middle of the productive period, stabilization occurs, and by the end of the productive period, there is a decrease in reproductive performance. The mating line gosling rate was higher than the paternal line throughout the egg-laying cycle and on average per season it was 47.87% for the maternal line and 46.1% for the paternal line.
