Effects of enrichment on veterinary treatment of laboratory rhesus macaques (Macaca mulatta)

For captive primates, environmental enrichment may improve psychological well-being, as indicated by changes in the frequency of species-typical and abnormal behaviours. The effects of enrichment on physical well-being have also been examined, but little attention has been devoted to the...

Behavioral effects of enrichment on pair-housed juvenile rhesus monkeys

Environmental enhancers were frequently utilized, and led to relatively small changes in behavior between control and enriched subjects, suggesting that the presence of a partner for juvenile rhesus monkeys acts as a form of enrichment that may dilute the effects...

Time investment in continuous implementation of an effective environmental enhancement plan

A well-functioning environmental enhancement plan for 1000 macaques requires a qualified person who commits at least 50% of her/his time to the day-to-day operation of the program.

Traditional handling procedures of laboratory nonhuman primates are an intrinsic source of distress: What can be done?

With some professional expertise and goodwill, there should be no real need to resort to forceful restraint when doing research with nonhuman primates.

Survey of environmental enhancement for research macaques

A survey of 11 facilities. The percentage of caged macaques permanently:a) exposed to enrichment objects ranged from 18% to 100% with a mean of 86%,b) housed in pairs or small groups ranged from 0% to 98% with a mean of...

Social enrichment for previously single-caged stump-tail macaques

Isosexual pair-housing of ten female and six male previously single-caged adult stump-tailed macaques (Macaca arctoides) was attempted. Partners were introduced to each other following the establishment of rank relationships during a three-day non-contact familiarization period. Pair formations did not entail...

Computer-task testing of rhesus monkeys (Macaca mulatta) in the social milieu

The data also reflect the importance of challenge and control, along with companionship and comfort, as essential dimensions of enrichment.

A garden of enrichment

The animals are spending a lot of time searching for different species of plants, not only because of their medicinal compounds but also because of their taste. Both seeking out and eating the herbs can occupy a lot of the...

Indirect and direct behavioural changes of individually housed rhesus monkeys (Macaca mulatta) as a function of manipulandum

The aim of this study was to determine whether exposing individually housed rhesus macaques to various manipulanda would not only decrease their frequency of 'unacceptable' behaviours (e.g., pacing), but also increase the frequency of 'acceptable' behaviours (e.g. presenting). ... The...
