Evaluation of an inexpensive custom-made food puzzle used as primary feeder for pair-housed rhesus macaques

Working for their standard food rather than collecting it from freely accessible food boxes did not impair the [pair-housed] animals' body weight maintenance, suggesting that their general health was not impaired by the new feeding technique.

Observations of increased activity and tool use in captive rhesus monkeys exposed to troughs of water

These results suggest that exposure to water sources may elicit a broad spectrum of species-typical activity and may be a simple and inexpensive way to enrich the environment of captive [group-housed] rhesus monkeys. ... Standing water was more effective than...

The resocialization and rehabilitation of humanized and abused primates

Author presents case histories of Primarily Primate's treatment of individual primates with problems common to humanized and abused primates. Among the methods effectively used were gradual introduction to other primates, (sometimes with the use of portable cages), surrogate mothers, territorial...

Empirical use of liquid supplemental nutrition for aged macaques

Four aged subjects (30 years and older) received 250 cc of Ensure in stainless steel bowls five times a week. The response was positive in all cases. Weight-loss stopped and the subjects regained their vitality (without showing adverse side effects...

Effect of group size on behavior of group-housed female rhesus macaques (Macaca mulatta)

This study shows that there are no significant effects of group size on social behaviors when comparing groups of four or five adult female rhesus monkeys.

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...
