Comprehensive literature review dealing with the following topics: a) Group housing versus single housing; b) Enrichment strategies using inanimate objects; c) Socialization with conspecifics; d) Role of animal care staff.
This paper will attempt to show the marked improvement in behaviour of a small group of female cynomolgus monkeys, after a period of routine training and human interaction. A relatively short, but predictable, course of...
Recent amendments to the Animal Welfare Act will, upon taking effect, require that researchers who maintain nonhuman primates in captivity house their animals in such a way as to “promote their psychological well-being.” Unfortunately, no...
Single-housed rhesus macaques were transferred to permanent pair-housing arrangements. The present investigation also demonstrates that pairing caged rhesus monkeys with compatible conspecifics does not interfere with a number of common research protocols [e.g., headcap implantation...
Subjects were exposed to a PVC pipe and to a gnawing stick uninterruptedly for one year. The singly caged monkeys spent on average 28% of the total observation time [120 min] with the PVC pipes...
Thirty scenes depict different adult rhesus monkeys [and one adult, male stump-tailed macaque], each paired with a compatible companion for up to two years. The following pair combinations and research situations are shown: adult male/male...
Single-housed rhesus macaques were transferred to permanent pair-housing arrangements. The present investigation also demonstrates that pairing caged rhesus monkeys with compatible conspecifics does not interfere with a number of common research protocols [e.g., headcap implantation...
General considerations for appropriate cage space arrangement for small monkeys.
This paper describes the introduction of a modified caging system and the benefits to both the animals and staff. The removal of metal grids at the bottom of the cage, and the introduction of direct...
Marmosets are among the easiest of primates to provide with environmental enrichment. Like other higher primates, they need companionship, adequate space with incorporated complexity, some unpredictability in the environment, ways in which they can manipulate...
