Abstract
Fluid and food intakes of Fischer 344 and Sprague-Dawley rats were compared in the 24 h after treatment with polyethylene glycol (PEG), and subjects were presented with drinking supplies of physiological saline or tap water. As in previous investigations, Fischer rats displayed relatively lower levels of ingestive behavior, a pattern that remained evident even in the longer post-PEG interval when animals drank copious amounts of the saline solution. These data therefore confirmed again that Fischer rats are more “economical” in their behavioral responsiveness, and that strain differences may exert noteworthy influences on research into the physiological controls of ingestive behavior.
