Oxygen consumption, activity and body fat in normal and hairless mice

The oxygen consumption spontaneous activity of A2G (hr/+), A2G (hr/hr) and NMRI mice in groups of 2, 3, or 5 were measured, and body fat content was also determined. Average rates of oxygen consumption were found to be lowest in the A2G (hr/+) and highest in the A2G (hr/hr) mice, and conversely for the proportion of total body fat. There was no difference in activity of A2G (hr/+) and A2G (hr/hr), but the NMRI mice were more active.
