Twenty-nine weaned rhesus monkey infants were removed from breeding troops to avoid overcrowding and were placed with unfamiliar singly caged adults without prior familiarization. Adult-infant pairs were compatible in 90% of cases. Compatibility depended neither...
A case study of one pair of rhesus macaques.
Autoaggression and stereotypies in individually housed cynomolgus monkeys were compared in a standard primate cage and an enriched playpen environment. Stereotypy and autoaggression were markedly reduced in the playpen, but reappeared on return to the...
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...
