Macaque

The effects of two novel objects on the behaviour of singly caged adult rhesus macaques

Single-housed subjects engaged in almond stick use 5.8% of 15 minute-observation sessions. The corresponding figure for nylon ball use was 2%. No adverse health effects of stick ingestion were noted among the subjects.

Changes in behavior and heart rate associated with pair formation in adult female rhesus monkeys (Macaca mulatta)

Mean heart rate increased significantly during pair housing. Bizarre postures decreased, while other abnormal behaviors including pacing, stereotypic actions, and self-injury did not change significantly. [Pair formation technique is not described.]

Effect of cage size and environmental enrichment on behavioral and physiological responses of rhesus macaques to the stress of daily events

Neither heart rate nor activity varied significantly between the two cage sizes [of barren cages]. Adult, single-housed female rhesus macaques responded with a significant rise in heart rate to being removed from their home cage and replaced after the cage...

Ecological requirements of macaques

In captive colonies, social and rearing environments and modes of provisioning often depart significantly from those that occur in nature. Within limits, naturalistic patterns can serve as useful models for improving the quality of life for captive macaques.

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...

Agonistic behavior responses of socially experienced, unfamiliar adult male rhesus monkeys (Macaca mulatta) to pairing

The present data demonstrate that unfamiliar adult male rhesus monkeys may generally be paired directly with each other without undue risk provided partners have previously lived with another male companion. This is congruent with the findings made with adult females....
