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...

Space utilization and social behaviors of chimpanzees (Pan troglodytes) housed under varying caging and social conditions

Affiliative behaviors and ambulatory activity were significantly greater when groups [one male plus 2 or 3 females] had less space. When they had access to several cages, the animals spend most of the time in one cage in close proximity...

Maternal anxiety in rhesus macaques (Macaca mulatta) I. Measurement of anxiety and identification of anxiety-eliciting situations.

Visual monitoring and scratching were used as behavioral indicators of maternal and social anxiety in small captive groups of rhesus macaques. Young infants were especially at risk from other group members during the first weeks of locomotion away from their...

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...

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...
