Psychological well-being of captive primates: Developing a facility plan to address social needs

Discussion of issues that must be considered when deciding how to house nonhuman primates socially. These issues include the kind of social arrangements, the introduction procedure, cage features and access by researchers to individual animals.

Improved handling of experimental rhesus monkeys

The significant increase of serum cortisol concentration associated with involuntary manual or mechanical restraint during venipuncture was absent in females who were trained to voluntarily cooperate during the procedure in the homecage. The present findings indicate that training rhesus monkeys...

Foraging for commercial chow

While sitting on swings, platforms or other elevated structures, or clinging to the mesh, individual animals seize a piece of chow [fruit, vegetable or bread] and retrieve a piece [through the mesh of the ceiling]. This simple 'food puzzle' not...

Environmental enrichment by varied feeding strategies for individually caged young chimpanzees

Providing an ear of unhusked corn daily or on alternate days, in addition to laboratory chow, resulted in more time spent contacting food [primarily the corn] an hour after feeding [34% & 55%] than feeding laboratory chow alone [8% &...

Environmental enhancement plan for previously single-caged adult rhesus macaques (Macaca mulatta)

To promote the well-being of previously single-caged adult (older than 5 years) rhesus macaques (Macaca mulatta) and the quality of research done with them, the following environmental enhancement plan has been developed and implemented at the Wisconsin Regional Primate Research...

Environmental enrichment branches that do not clog drains

More than 700 caged rhesus and stump-tailed macaques housed in 29 rooms have been exposed to red oak perches and/or loose branch segments for a period of six months. Drains did not clog in any of the 29 rooms during...

Difficulty in training juvenile rhesus macaques to actively cooperate during venipuncture in the homecage

The relatively large amount of time invested with little success does not make training of juvenile rhesus macaques attractive enough to be recommended as a routine management procedure.

Are rhesus macaques really so aggressive?

Several years of experience with pair housing of previously single-caged adult rhesus macaques and venipuncture in the home cage of cooperative, non-resisting animals lead the author to conclude that rhesus macaques are not as aggressive as commonly believed.
