The aim of the research is to determine the effect of vitamin C (Ascorbic acid) injected at different doses on the hatchability of eggs obtained from domestic geese raised in the Afyonkarahisar region. Injected doses of vitamin C, 8 and 10 mg were applied to the air cell of the eggs on the 24th day of incubation. As a result of the experiment, vitamin C given to fertile goose eggs positively affected hatch weight, chick length, and chick quality. There was no significant difference between the groups regarding hatchability and survival rate.
