Summary
The ontogeny of O2 consumption of avian embryos differs with size and condition at hatching. Altricial species do not exhibit the plateau phase observed in precocial species. Large precocial species exhibit a more pronounced decline in metabolic rate during the latter phase of the incubation period then do small precocial species. It is suggested that these differences may be due to differences in the pattern of growth. In spite of these differences, the rate of O2 consumption immediately prior to pipping is roughly proportional to the 3/4 power of fresh egg mass.
