Influence of non-ventilating intervals during early incubation stage on egg hatching process.

Background And Aim: The exchange of oxygen and carbon dioxide (CO) in the incubator plays a key role in embryonic development and hatching. This study aimed to study the effect of non-ventilated (NV) intervals during the early stage of embryonic development on the hatching process.

Materials And Methods: Hatching eggs (n = 7200) were equally divided into four treatment groups and incubated in four incubators.
