Abstract

Male rats were exposed to conditions of either postweaning olfactory enrichment or standard laboratory rearing. In later tests, rats exposed to olfactory enrichment consumed more of novel substances (sucrose and milk)_than did laboratory-reared controls. Animals presented with milk and then sucrose drank more of both substances than animals presented with the substances in the reverse order. The results suggest that the variety of odors to which the weanling rat is exposed affects its later preference for dietary variability.
