title: The influence of maternal labels on dietary preferences of spiny mouse weanlings.
abstract: To assess the influence of conspecific chemical cues on the development of dietary preferences, spiny mouse (Acomys cahirinus) weanling were tested for their responses to food items that were partially eaten (thus, presumably labeled) by various categories of conspecifics. Consumption of a highly preferred novel food (fresh carrot) labeled by the pups' parents, or mother alone, was greater than that of a clean sample of the same food. The presence of labels emanating from the father or an alien mother had no effect on food consumption. Salient maternal labels that elicit preferential feeding by young appear to be individually unique, therefore allowing pups to recognize such cues emanating from their own mother. The attractive substance that mothers transfer to food items while eating (the maternal label per se) has not been identified, but saliva is a likely candidate.
