Baboon vocalizations as measures of psychological well-being

Increased grunting was associated with environmental enrichment [radio, food treats]. Thus vocalizations may provide a useful tool for evaluating enrichment programs designed to promote baboon, and perhaps other nonhuman primate, psychological well-being. ... With minimal training, caregivers can learn to...

Letter to the Editor: Is cortisol a good measure of an animal’s response to cage size? American Society of Primatologists (APS) Bulletin 17(4),

The validity of cortisol being used as variable to assess animal welfare regarding living space is questioned. There are strong financial reasons for housing animals in small enclosures. It is important to collect data on animals' responses to these cages,...

Urinary cortisol responses of longtailed macaques to five cage sizes, tethering, sedation, and room change

In the tethering study cortisol levels remained somewhat elevated 2-4 weeks after catheterization. After the catheters were removed, the cortisol levels dropped rapidly although they remained slightly elevated through the recovery phase.

Pre-feeding agonism and seasonality in captive groups of chimpanzees (Pan troglodytes)

Enriching the environments of groups of captive chimpanzees by providing a variety of attractive foods (fruit) does not seem to increase tension or lead to increased pre-feeding agonism. Managers should be encouraged to provide a varied diet reflecting the food...

Appetite and urinary cortisol responses to different cage sizes in female pigtailed macaques

Appetite during the first three days in the new room was moderately suppressed. Appetite and cortisol levels were unrelated to cage size.

A simple device for stimulating gummivory in tamarins (Saguinus)

A simple, custom-made gum-tree was tested. The artificial gum-tree was hung vertically from the top of the cage with two screw hooks, and placed ideally two or more feet from existing branches and cage walls. All tamarins under 3.5 years...

Consequences of restraint stress on natural killer cell activity, behavior, and hormone levels in rhesus macaques (Macaca mulatta)

Animals were chair restrained and samples taken after 1, 2 and 3 hours. WBC and the percentage of neutrophils increased during the restraint period, while the percent lymphocytes and monocytes decreased. NK [natural killer cell] activity also decreased over time...

Regurgitation and reingestion in a captive chimpanzee (Pan troglodytes)

Our findings suggest that behavioral training [negative/positive reinforcement] coupled with a dietary change [replacing fruit with vegetables and browse] may reduce regurgitation activities.
