Husbandry, handling, and nutrition for marmosets.

ABSTRACT

Marmosets, especially Callithrix jacchus, have become an established part of the laboratory animal community. Information on marmoset life history, behavior, and diet acquired from experience with natural and captive habitats has increased, but the early information from workers with colonies, principally those of tamarins, has led to some common perceptions about how to house, handle, and especially, feed callitrichids that may not apply to marmoset requirements. The availability of commercially produced, almost-complete base diet components and a wider variety of cage construction materials, combined with the recent emphasis on the integration of engineering and performance standards for housing, have made captive life and the implementation of research requirements better for the animals and the people that work with them. We will review some of the routine aspects of husbandry, handling, and nutrition for marmoset monkeys maintained in a research setting.
