Post-deprivation effects with two energetic alternatives in rats

Abstract

Twenty-four albino rats (3-month-old at the beginning of the experiment) divided in four groups, were exposed to fifteen days of free access to water and food, followed by 3 days of food deprivation. Next five days every group was exposed to one of three kinds of water concentration of glucose. First concentration had 45g of glucose /200ml of water (180 calories), second 30g of glucose /200ml of water (120 calories), and third 15g of glucose /200ml of water (60 calories). Control group never received water concentration of glucose. Caloric food concentration remained the same. Food was available at all times during free access periods. Results suggest that modification of caloric water concentration affect the feeding behavior after food deprivation period.
