Abstract
Summary
Hepatic vit. A levels are much higher in cold-acclimated rats than in rats maintained at 25°C. This increase in hepatic vit. A content does not stem from a sparing action induced by cold acclimation but is rather a simple corollary of increased food consumption that accompanies cold-exposure. Moreover, evidence is presented which suggests that the amount of vit. A needed for rats to live at 0-2 °C is not markedly greater than the amount needed to live at 25 °C.
