Effects of repeated restraint stress at 30-minute intervals during 24-hours on serum testosterone, LH and glucocorticoids levels in male Japanese monkeys (Macaca fuscata)

30-min intervals sampling [using compulsory restraint ] serum testosterone levels decreased and glucocorticoid levels increased, respectively, immediately after the start of blood sampling. LH levels were not affected.

Diving and underwater swimming as enrichment activities for captive rhesus macaques (Macaca mulatta)

In order to assess the environmental enrichment value of a small swimming pool for captive juvenile rhesus macaques (Macaca. mulatta), observations of social and individual behaviours were made during baseline and experimental (pool) conditions. When the pool was available there...

Behavioral effects of enrichment devices on laboratory primates with stereotypic and self-directed behavior

Single-caged long-tailed macaques showed a decrease in self-directed behavior, especially self-biting, floating limb, hair pulling, and excessive licking, when treats were in the feeder. Paradoxically, both pacing and rocking increased when treats were in the feeder. A temporary reduction in...

Reasons and risks associated with manipulating captive primates’ social environments

Review of the implications of experimental or management-related manipulations of the social environment of captive primates for the animals' welfare. Relatively little empirical work has been done on the effects of manipulation of the social environment. The data currently available...

Groups were formed by releasing future group members in same enclosure. Within the first five months after group formation one of 26 animals died and two were killed due to trauma resulting from fighting. We decided to use the webinar...

Results of providing swings to individually housed rhesus monkeys (Macaca mulatta)

The single-housed adult test subjects manipulated the swings but showed little inclination to actually use them for swinging.

Sex differences in compatibility of pair-housed adult longtailed macaques

Prefamiliarized partners were paired without ascertaining that they had established their dominance-subordination relationship. Newly formed pairs were separated for 17 hours and subsequently reintroduced daily during a study period of 23 days. Under these extraordinary circumstances male/male pairs were less...
