Abstract

Intake of food by hungry rats was reduced 50 percent below normal after their blood had been mixed with that of satiated rats. Intake of food by deprived rats was not reduced when the donor rat was deprived of food for 24 hours prior to mixing of the blood or when a deprived donor was fed to satiety immediately before such transfusion.
