Rawhide ‘chew-bones’ reduce abnormal behavior in individually housed adult rhesus macaques

Self-clasp showed a significant decline when the rawhide bones were present. We conclude that rawhide chew-bones are an effective, and relatively inexpensive method of enriching the environment of individually housed rhesus macaques.

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.

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.

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,...

Relationship between social factors and pituitary-adroneocortical activity in female rhesus monkeys (Macaca mulatta)

Psychosocial stress in humans has been related to the occurrence or progression of certain diseases and a positive social environment has been shown, in some cases, to ameliorate this effect. In many experimental studies changes in serum cortisol levels have...

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...

Affiliation tactics prior to a period of competition in captive groups of stumptail macaques

We show that, subjected to predictable daily routines, captive stumptail macaques adjust their affiliative interactions as if maximizing the benefits of a particular relationship. For 8 months the frequency of diurnal social grooming interactions and competition to groom a third...

A semi-natural habitat for housing small, nonhuman primates

A semi-natural habitat that was designed to house a group of squirrel monkeys is described. Animals maintained in this environment were healthy, and none of the animals exhibited locomotor stereotypies. This facility was easier and more economical to maintain than...
