I have been measuring the metabolic rates (O2 consumed and CO2 produced) in bobwhite quail embryos at different temperatures. The average RQ is about .51.
How is this possible? I thought RQ should range between .7 and 1.
Thank you!
The prerequisite for the RQ between 0.7 and 1.0 is constant body mass. The embryos are losing weight in the egg.
I don`t know exactly about the bird embryo, but one of paper that I read mentioned that consumption and CO2 production could only measured after day 12 of incubation because concentrations of these gases are very small during the early periods of incubation. But they did it on chicken embryo, hopefully it will work for you
@Maharani
Could you please cite this paper, as that would be interesting to all? Thanks!
my measurements start around the 8th day of incubation. the unusu al RQs continue throughout their development. Thanks to all who have replied.

If there is any carbon dioxide retention taking place, subsequent to perhaps some acid accumulation, there can be low RQs. In goldish, low RQs were observed during recovery phase after a hypoxic exposure.
