Evaluation of social enrichment for aged rhesus macaques

The effect of a compatible companion on the behaviour and bodyweight of eight previously single-caged, 31-36 years old rhesus macaques was assessed 16 months after pair formation. The aged subjects preferred to stay in close proximity with their companion even...

Using the mesh ceiling as a food puzzle to encourage foraging behaviour in caged rhesus macaques (Macaca mulatta)

An attempt was made to encourage more foraging behaviour in eight pair-housed adult rhesus macaques (Macaca mulatta). No special device and no special food were used. Daily commercial dry food rations consisting of 33 bar-shaped or 16 star-shaped biscuits per...

Nonspecific diarrhea in the alpha-male of a breeding troop: A case report

Bob's prompt recovery from intractable diarrhea upon being removed from his troop suggests that asserting his role as alpha-animal constituted a chronic social challenge that may have altered his resistance to facultative pathogens and/or autonomic neural tone, to produce diarrhea.

Enticing nonhuman primates to forage for their standard biscuit ration

Ordinary feeder-boxes were converted into food puzzles by remounting them onto the mesh of the front of the cages, away from original access holes. The total amount of time [pair-housed] adult male rhesus macaques engaged in gathering the standard biscuit...

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.
