Development of olfactory control of feeding-site selection in rat pups

The results of the present experiments provide two lines of evidence consistent with the view that development of olfactory control of feeding-site selection in rats depends on experiences during ontogeny. First, normally reared pups ate at a feeding site at which either an anesthetized conspecific or conspecific excreta were present in preference to a clean site, whereas pups reared without contact with conspecifics were not influenced in …
