Effects of housing differences upon activity budgets in captive sifakas (Propithecus verreauxi)

Access to an outdoor environment [which was smaller than the indoor environment] significantly diminished inactivity and stimulated locomotion, feeding, and playing.

Environmental enrichment for confinement pigs

Pigs have definite toy preferences. If a ball rolls into the manure they will no longer play with it. This is why we used suspended from the ceiling. Then the young pigs are given a choice between hanging chains, cloth...

Cage enrichment, behavior, and physiology in nursery-reared rhesus monkeys

Calm [single-caged] control animals and stressed [single-caged] enriched animals exhibited higher cortisol values. The enriched animals had lower cortisols when they appeared calm and higher cortisols when they appeared stressed.

Differential behavioral and adrenocortical responses to stress among three macaque species

Training technique is described to ensure that single-housed subjects voluntarily entered a transfer box. Bonnets took longer to train than rhesus or crabeaters.

Visitors excite primates in zoos

Fifteen species of primate were observed to assess the effects of zoo visitors on their social behavior. When visitors were present primates were less affiliative, more active, but more aggressive. These changes were particularly marked in arboreal monkeys. It is...
