Engineering a rational approach to primate space requirements

The subjects spent significantly more time on the front half of the perch in the standard cage. ... On the basis of this observation, we highly recommend that solid-sided cages be placed in rooms such that the perches are installed...

Formation of outdoor multimal breeding groups of rhesus macaques

Gradually forming new breeding groups resulted in 0.27 severe wounds per individual per year; rapidly forming new groups resulted in twice as much wounding.

Food puzzle feeders: Effects on self-biting and stereotypy in individually housed monkeys

Subjects were observed not only when the food puzzle feeder had just been filled in the early morning but at several other time points throughout the day. ... There was no effect on self-aggression; however, a reduction in active stereotypic...

Group formation of female pigtail macaques (Macaca nemestrina)

Eight adult females and one adult male were moved from individual cages and simultaneously introduced. The animals showed conspicuous physiological stress responses though they established a dominance hierarchy with no serious fighting and a complete absence of wounding.

The effectiveness of cage toys in reducing abnormal behavior in individually housed pigtail macaques

Abnormal behavior accounted for 24% [!] of the time during baseline observations. The repeated provision of several toys resulted in a significant decrease in abnormal behaviors during the first 30 minutes. The new toys were used for 27% of the...

Effect of companions in modulating stress associated with new group formation in juvenile rhesus macaques

To determine if the presence of one or more familiar peers buffers the physiological effect of a stressor, 10 juvenile rhesus monkeys were removed from their natal group and placed together to form a new peer group. Six of the...

Goldfish as enrichment for singly housed chimpanzees

The aquarium [with a single goldfish] was attached to the outside of the chimpanzee's cage ... so that the single-caged subject was able to touch the aquarium but not the fish itself. At the conclusion of this study the authors...

Multiple daily dosing regimens need not be a barrier to group housing of primates undergoing toxicology studies

It is demonstrated how same-sex group-housing of long-tailed macaques and regulatory toxicology are compatible.

The effects of cage size and complexity on the behaviour of captive common marmosets, Callithrix jacchus jacchus

Pair-housed marmosets showed a significant increase in perching plus a significant decrease in stereotypic and aggressive behavior several months after being transferred from their small home cages equipped with a nest box and two branches to double-size cages that were...

Hormonal response to restraint in rhesus monkeys

These experiments indicate clearly that placement in a restraining chair represents a stimulus of different systems in monkeys. The responses observed in the present study are predominantly psychoendocrine responses to unconditioned emotional stimuli associated with the chair-restraint situation, despite the...
