Voluminous sucrose consumption in female rats: increased "nippiness" during periods of sucrose removal and possible oestrus periodicity

Psychological Reports

Abstract

In a two-bottle paradigm in which water and 10% sucrose water were always available, female rats drank about 200 cc of the sugar water (about 65 g of sucrose/kg) per day for 4 wk. There were no significant decreases in consumption over this time. In Exp. 2 female rats singly housed were given two bottles containing water for 1 wk. and then a bottle containing water and a bottle containing 15% sucrose for the next week for 6 wk. When sucrose was available, the rats ate 33% more rat chow. When sucrose was removed, the rats displayed more episodes of biting a stimulus when the food cubes were being removed for daily measurements. Some females exhibited a marked 4- to 5-day periodicity in sucrose (7.5%) consumption. The persistent and voluminous consumption of sucrose water and enhanced agonistic-like behavior during periods of withdrawal suggests the presence of a robust phenomenon with potential dinical applications to the challenge of addiction.
