Abstract :Inbreeding, which is the mating of related individuals, increases homozygosity and leads to depression, especially in traits with low heritability. In this study, parent-offspring, full-sibling and half-sibling mating groups were formed and their effects on embryo loss and hatch weight were investigated. In the study, a total of 2130 fertile Japanese quail eggs were used. Embryo losses were divided into three periods; early period insert ignore into journalissuearticles values(first 5-day);, middle period insert ignore into journalissuearticles values(6-12th days); and late period insert ignore into journalissuearticles values(13-17th days);. It was observed that mating groups affect all traits subject of this study insert ignore into journalissuearticles values(P≤0.0001);. The lowest hatchability of fertile eggs was observed in dam-male offspring mating insert ignore into journalissuearticles values(DM);, while the highest was observed in half-sibling insert ignore into journalissuearticles values(HS); and control insert ignore into journalissuearticles values(C); matings insert ignore into journalissuearticles values(P≤0.05);. However, the highest hatch-weight were found in eggs of DM matings insert ignore into journalissuearticles values(P≤0.05);. DM has also the highest embryo losses for all periods insert ignore into journalissuearticles values(P≤0.05);. Most of the embryo losses, except the half-sibling group, occurred in the early period.
