dc.description.abstractThe quail eggs produced by young and old flock hens (2 and 8 months old) were incubated at three different hatchers for two days at the plateau stage of incubation. The hatcher temperatures were adjusted to 36.4 degrees C (Low-L), 37.4 degrees C (Control-CON) and 38.4 degrees C (High-H), respectively. Mean eggshell temperatures have shown different trends among groups, both for temperature and age main effects (P < 0.01). A significant interaction occurred between IC temperature and flock age at 38.4 degrees C (P < 0.05) for the percentage of chicks hatched. At prenatal stage, a significant interaction effect was detected between groups at 38.4 degrees C (P < 0.05). A significant interaction occurred between temperature and age group for yolk sac weight both at 37.4 and 38.4 degrees C IC temperatures (P < 0.10). The study suggests that the response of quail embryos to the IC temperature at the plateau stage of incubation varies when viewed at different ages. The information may suggest that different temperature levels may be required at the plateau stage of incubation with eggs of each age for the optimization of hatching results. The application of 36.4 and 37.4 degrees C IC temperatures at plateau stage of incubation seems to be more convenient for both of age groups than 38.4 degrees C IC temperature. Although, the plateau stage is around between 14 - 15 days of incubation in quails, the plateau stage should be reinvestigated depending on the age of parent. It might be recommended that the old and young parent eggs should be set at different temperature levels for plateau stage of incubation. Particularly, temperature increases should not be allowed for eggs of old parent hens at the plateau stage of incubation.en_US
