Normalizing laboratory-reared rhesus macaque (Macaca mulatta) behavior with exposure to complex outdoor enclosures

Young group-housed animals housed in the outdoor corncrib also showed a decline in self-oral behaviour which persisted even upon return to the laboratory environment.Abstract of this work has been published in:American Journal of Primatology 18: 158, 1989; Novak MA, O'Neill...

Training adult male rhesus monkeys to actively cooperate during in-homecage venipuncture

A training technique is described for ensuring the active cooperation of 10 pair-housed and 5 single-housed adult male rhesus monkeys during in-homecage venipuncture. Mean cumulative training time investment per male was 40 minutes. Once trained, all males cooperated during in-homecage...

Social enrichment for aged rhesus monkeys who have lived singly for many years

There is widespread concern that aged rhesus monkeys who have been housed singly for a long time would do better living alone than sharing a cage with a companion. Ten female and five male rhesus monkeys, 22 to 33 years...

Impact of venipuncture on physiological research conducted in conscious macaques

A survey of 397 publications dealing with macaques was conducted. Stress-sensitive physiological data collected during venipuncture were evaluated in 58 reports. Despite of the fact that venipuncture often is a stressful event for research animals, 81% of the studies did...

Group formation of previously single-caged adult rhesus macaques for the purpose of environmental enrichment

An attempt was made to form two groups of 6 previously single-caged adult female and 6 previously single-caged adult male rhesus macaques. The study was based on the premise that simultaneous introduction of familiar animals reduces the risks involved during...

Puzzle feeder for orangutans

The puzzle feeder was used constantly until all the food had been consumed (up to one hour). Dominance within the group affected individual access to the puzzle.
