Influence of single caging on cellular immune function in female cynomolgus macaques (Macaca fascicularis)

Immune responses are affected by housing condition. These findings suggest that single caging modulates several aspects of cellular immune function in female cynomolgus monkeys.

Changes in activity levels of singly housed longtailed macaques when given the opportunity to exercise in a larger cage

Over a period of 36 days, each [single-housed] animal had 15 min per day access to a multicompartmental [large] exercise cage. Locomotion increased while stereotypical behavior decreased when the animals were in the exercise cage.

Activity patterns of captive and free-ranging long-tailed macaques (Macaca fascicularis)

In summary, the wild and captive macaques exhibited significant differences in four of the six activity categories we examined. There was no significant difference in the amount of grooming between the two populations counter to our expectations. Overall, the activity...

The effects of elementary environmental enrichment on the behavior of captive Java macaques (Macaca fascicularis)

The aim of this study was to determine the short-term effects of simple, cost-effective enrichment techniques. .... In the presence of simple enrichment [ranging 'from food to foliage to plastic objects'], isolate housed macaques showed slight decreases in abnormal behaviors...

Conflict avoidance among rhesus monkeys: coping with short-term crowding

Two contrasting models were examined, each of which predicts a relationship between space and aggression in primates. A 'spatial density' model predicts that as spatial densities increase aggressive responses also increase. A more recent 'coping model' suggests that, over long...

Old, socially housed rhesus monkeys manipulate objects

More than 10% of the [group-housed] females' time was spent in object [toy] manipulation. ... Socially housed rhesus monkeys ranging in age from 14 to 22 years showed steady rates of object manipulation, and their interest in familiar objects did...

Potential animal hazard with ring toys

Recently one animal, a 2-year-old pigtail macaque (Macaca nemestrina), approximate weight 3.1 kg, became trappedinside a Nylaring. The ring went around the neck, across the body, and under one arm. Since the animal was apparentlyunable to remove the ring, he...

Initial response to introduction of a PVC perch by singly caged Macaca fascicularis

Longtailed macaques ... exhibit a vertical flight response when alarmed. Therefore, the height of the cage is important for allowing the animals to withdraw from potentially stressful or alarming situations. ..Single-housed monkeys spent significantly more time clinging to the cage...

Weight gain among juvenile rhesus macaques: A comparison of enriched and control groups

Subject monkeys gained weight at the highest rate during group-housing, suggesting that the combination of food availability, exercise opportunities, and chronologic age during this portion of the study were conducive for rapid weight gain.
