Abstract
1. The effect of thermal environment and administration of progesterone upon minimal oxygen consumption and thermal stability of the new‐born guinea‐pig has been investigated. 2. It was found that the ambient temperature at which the new‐born is reared does not influence minimal oxygen consumption although it modifies the response to cold. 3. Thermal stability was decreased in animals raised in a warm environment. 4. Minimal oxygen consumption per unit body weight during the neonatal period increased 25%, most of the increase taking place within 16 hr after birth. 5. Decrease in the relative mass of brown adipose tissue was least in new‐borns maintained at a high ambient temperature. 6. Administration of progesterone did not affect oxygen consumption, body temperature and thermal stability of the new‐born.
