Fischer-344 rats were acclimated to a daily 15 min period of water availability. After water consumption had stabilized, the rats were permitted a 15 min access to 0.15% (w/v) solution of saccharin. One to two min following saccharin presentation, they were given various doses of acrylamide (10-50 mg/kg) or lithium chloride (LiCl; 3 mEq/kg) by gavage. Three days later, aversion to the saccharin solution was determined. Acrylamide, like LiCl, produced an aversion to saccharin. The effect of acrylamide appeared to be dose-related with the threshold dose being 10 mg/kg.
