Inexpensive outdoor enclosure for Japanese macaques used in biobehavioral research

We effectively and humanely enclosed nine Japanese macaques in an ellipse 32 x 40m, with a 1 m high chain-link fence surmounted by a 3 m curtain of electrically conductive nylon net. High-voltage brief-pulse charges prevent climbing on the net....

Kong toys as enrichment devices for singly-caged macaques

Providing objects such as Kong toys to macaques in single-animal housing with little or no opportunity for manipulation is mildly enriching to some of the monkeys. Periodically removing and reintroducing the toys would increase their enrichment value.

The training of cynomolgus monkeys and how the human/animal relationship improves with environmental and mental enrichment

This paper will attempt to show the marked improvement in behaviour of a small group of female cynomolgus monkeys, after a period of routine training and human interaction. A relatively short, but predictable, course of routine handling and feeding enabled...

Enriching the lives of captive primates: issues and problems

Discussion of the concept of 'psychological well-being'. For troop-living primates such as rhesus monkeys, the best way to promote their well-being in the laboratory may be to rear them with partners or in social groups. ... Before we conclude that...

Free-environment rooms as alternative housing for squirrel monkeys

Individual and gang cages were removed from two conventional colony rooms and the monkeys [11 females and 5 males] were simply released into the rooms. ... Immediately following the establishment of these two free-environment rooms, a few monkeys incurred sprains...
