Abstract
Environmental enrichment may affect infant care and development in captive primates. We investigated the effects of this factor in laboratory common marmosets (Callithrix jacchus). An enriched physical environment enhanced the social activities of the marmosets and elicited a greater repertoire of behaviors, without negatively affecting the provision of infant care. In addition, infants in enriched cages displayed certain behaviors sooner than infants in non-enriched cages did, which suggests an increased developmental rate. Infants in enriched cages also ate more solid food and engaged in solitary play and exploration more than ones in non-enriched cages did. Play and exploration probably improve spatial cognition and motor skills, which, together with a higher degree of independence, may allow infants to cope better with laboratory routines and general social interactions later in life than their counterparts reared in less complex enclosures. We conclude that laboratories can significantly increase the welfare of marmosets by providing a more complex physical environment.
