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...

Caged rhesus macaques voluntarily work for ordinary food

Eight single-caged adult rhesus macaques were given the choice of freely collecting their standard food ration, i.e. 33 biscuits, from an ordinary food box or working for its retrieval from a custom- made food puzzle. During a one-hour observation session...

Enrichment options: Rotating logs for great apes

The logs are fixed as far outside the ceiling fence as they only can be reached with selected branches provided by the keepers. Using these sticks, the apes have to bring the log out of equilibrium and turn the log...

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...
