Abstract (2. Language): 
Oxygen consumption of eggs of quail which is belong to precocial groupe, were measured during artificial incubation at 37.5 - 37.8 °C constant temperature and 60% - 85% relative humidity. During incubation, the embryo consumes at first more oxygen from day to day until a plateau phase in which the oxygen consumption remains more or less constant, even declines. The plateau phase takes place at 13. to 16. days (76% to 94% of total incubation period). Rate of oxygen consumption then increases again to a maximum just prior to hatching. Total energy requirement during embryonic development was calculated as 26.38 kJ, corresponding to 113.3 ml oxygen per gram of initial egg mass.
Abstract (Original Language): 
Prekosyal kuşlar sınıfına giren bıldırcın embriyolarının, 37,5 - 37,8 °C sabit sıcaklık ve %60 - %85 oransal nem koşullarındaki kuluçka boyunca gösterdikleri oksijen tüketimi ölçülmüştür. Kuluçka sırasında, embriyonun önce günden güne artan miktarda oksijen tükettiği ve bu, tüketimin yaklaşık olarak aynı düzeyde kaldığı, hatta azaldığı duraklama evresine kadar sürmüştür. Duraklama evresi 13. - 16. günler arasında (toplam kuluçka süresinin %76 - %94’ü) görüldü. Oksijen tüketim oranı daha sonra yeniden yükselmiş ve çıkışın hemen öncesinde en yüksek düzeyine ulaşmıştır. Embriyo gelişimi boyunca kullanılan toplam enerji 26,38 kJ olarak hesaplanmıştır. Bu değer, yumurta taze kütlesinin her gramı için 113,3 ml oksijene karşılık gelmektedir.
