Recycled plastic cages and environmental enrichment devices

Although the production and use of recycled plastic lumber is still in its infancy, our experience indicates that this is an ideal material for the construction of environmental enrichment devices for monkeys ... especially in outdoor facilities and zoological collections.

Removal of a trauma-inflicting alpha matriline from a group of rhesus macaques to control severe wounding

Results identify an unusual outbreak of serious wounding by the alpha matriline of a large captive group [of rhesus macaques] and indicate that identification and removal of the animals responsible can be an effective management procedure for controlling such injuries.

Rate of habituation to an enrichment device by rhesus macaques with lesions of the entorthinal cortex, hippocampal formation, or parahippocampal gyrus

Significant differences were found in the rate of habituation [to a rubber ball serving as enrichment] between animals with entorhinal or hippocampal lesions and normal control animals. This study addresses the special needs of monkeys with experimental cortical lesions and...

Short-term evaluation of a foraging device for non-human primates

In the USA, any institution involved in using non-human primates for research has had, for regulatory reasons, to address the psychological needs of these animals. Enriching the environment through the use of foraging devices has been one method and a...

Effect of a preferred companion in modulating stress in adult female rhesus monkeys

Adult female rhesus monkeys exhibited a profound stress response when removed from their social group to a novel environment. Recovery time [of T cell subsets] was significantly enhanced by the presence of a preferred companion.

When trying to get your monkeys to behave, try perches

Higher perching elevations appear to be a very desirable feature in this environment for the expression of six of the twelve behaviors studied. Mid-level perches, on the other hand, were utilized more for only two of the behaviors: self play...

Expression of species-specific behavior in rhesus monkeys

High level perches were preferred over medium level and low perches for sleeping, social grooming and sitting. There were no overall age-effects on the use of perches. ... The availability of escape routes to outside areas reduced stress caused by...

Caged stumptailed macaques voluntarily work for ordinary food

Ninety-nine of the biscuits were placed in a freely accessible dish attached to the mesh of the front of the cage. Thirty-three biscuits were offered in a food puzzle. Twenty-five percent (4/16) of the subjects ignored the food puzzle during...

Primary forage feeder for singly-caged macaques

Perforated feeder box requires the single-housed subject to use the fingers to maneuver biscuits to access holes at different levels. Apparently the animals consumed nearly all the food retrieved from the forage feeders, leaving less on the cage floor to...
