Bıldırcınlarda (Coturnix coturnix japonica) embriyo metabolizması
, 2020 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 ...
