Environmental enrichment for a captive group of Sulawesi macaques (Macaca nigra)

Examination of individual activity budgets suggests that these [feeding] enrichment devices do not benefit all individuals [of the group] and may lose effectiveness in the long term.

Problems in evaluating the success of environmental enrichment ideas for captive primates

A plea will also be made for some standardization of methods for evaluating the success of enrichment devices and techniques.

Woodchip bedding as enrichment for captive chimpanzees in an outdoor enclosure

The use of woodchips as bedding for 16 juvenile chimpanzees (Pan troglodytes) was evaluated for the effects on behaviour, health and husbandry practices. Woodchip bedding was placed in two outdoor play areas for five consecutive days. Behavioural data were recorded...

The effects of cage size and pair housing on the behavior of captive chimpanzees

Environmental manipulation was higher and inactivity lower in the [furnished] large single cage than in the [furnished] small single cage. The mean abnormal behaviors decreased in the larger cages but the difference was not significant. ... During the paired condition,...

Enriching the lives of captive primates

The author reviews improvements in the behavioral management of a colony of captive chimpanzees at the Southwest Foundation for Biomedical Research. Environmental enrichment techniques, such as providing increased opportunities for physical, sensory, and feeding stimulation, as well as improvements in...

Chronic social stress, affiliation, and cellular immune response in nonhuman primates

Animals in the unstable [group-] condition also demonstrated relatively suppressed immune response. More affiliative animals showed enhanced immune response, with the beneficial effects of affiliation occurring primarily among unstable animals. The data are interpreted as consistent with the stress-buffering hypothesis;...

Consideration of primate ecology as behavioral enricher

Review of early enrichment studies with very useful recommendations. Housing should be dynamic and entertaining in structure and function. Largest areas practical should be provided with appropriate perching in various configurations to reduce constant visual contact between animals. ... Perhaps...

The relationship between forage material and levels of coprophagy in captive chimpanzee (Pan troglodytes)

Coprophagy scores were higher when chicken scratch or sweet feed [cracked corn, grain, rolled corn/barley] were available than when popcorn was available. Levels of coprophagy may be lowered by offering wadging materials [e.g., corn cobs, fruit pits, cardboard, fruit peels]...
