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...

Environmental enrichment and its effects on the individual

In macaques and baboons, stereotypy is reduced or stopped by supplying "one or more perches ... and other cage furniture", especially "a woodchip substrate which includes food items ... as provisioned substrate for foraging"

Methods to evaluate the well-being of laboratory primates

Single-caged long-tailed macaques took on average 8.7 seconds, paired tamarins took on average 15 seconds to retrieve one raisin from the pickup board [miniature ice cube tray attached to front of cage]. Experienced macaques emptied the commercial puzzle filled with...

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.
