Assessing the welfare of captive primates: A critique

Enrichment literature is reviewed and the concept of psychological space [encouraging the animal to behave as if it were in a larger space (e.g., hiding food with wood-chips)] discussed.

Effects of different environmental enrichment devices on cage stereotypies and autoaggression in captive cynomolgus monkeys

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 home cage. Some of the...

Developing housing facilities for rhesus monkeys: Prevention of abnormal behaviour

In rhesus macaques stereotyped locomotion was reduced from about 20% of observation time on average when the subjects were housed alone to about 4% when the subjects had been transferred to group-housing.

Influence of age of weaning on the behaviour of rhesus monkeys

Stereotypical locomotion was reduced by the presence of a social partner. ... Results also indicated that the rather early age of weaning of infants as practised in the course of the breeding procedure was an important factor in the induction...

Comparison of the reconciliation behavior of stumptail and rhesus macaques

Observations were made following spontaneous aggressive incidents in a breeding group of captive stumptail macaques (Macaca arctoides). Participants were observed both during the first 10 min following the aggressive incident, and during matched-control observations. Data on 670 pairs of former...

Studies of disturbed behaviour in macaques

Stereotyped locomotion amounted to about 20% of the time when the subjects were housed solitary. The amount of time spent in this behaviour was reduced to about 4% when the subjects had one or more social partners. Stereotyped locomotion was...
