Animal welfare and enrichment: A preference study in the common marmoset (Callithrix jacchus) (2004)

Manciocco, A., Puopolo, M., Vitale, A.

Abstract

In general, the results showed that the monkeys choose much less than expected between fruits cut and presented as usual in an open dish and fruit inserted as a whole in a pointed branch. When choosing a particual enrichment, it is important to consider the housing history of that particular colony. A considerable variability in preference of certain enrichment options was noted between and within families .
