Eggs of two broiler chicken lines differing in body fat content were incubated and oxygen consumption of single embryos was measured on days 14-19 of incubation with an indirect calorimeter. The objectives of this study were to investigate oxygen consumption patterns of the two genetic lines in the late stage of embryonic development (days 14-19) and the relationship between this pattern and body composition of the bird at 8 wk of age. Oxygen consumption for the genetically lean line (LL) was higher (P 0.05) than that for the genetically fat line (FL) for days 14 and 15 of incubation, while no differences were detectable after day 16 of incubation. The average oxygen consumption over the 6 d of measurement tended to be higher (P
