The purpose of this study was to test whether long-term pair housing of male rhesus macaques ameliorated negative responses to stressful events that can occur in the course of routine husbandry or research procedures. Twelve...
The use of substrate can have benefits to group housed macaques, including decreased aggression and increased foraging. Still, in some facilities, the use of bedding is perceived as time intensive and costly. In this study...
Introducing singly housed rhesus macaques (Macaca mulatta) into isosexual pairs is widely considered to improve welfare. The population of laboratory rhesus macaques is heterogeneous on a variety of factors and there is little literature available...
There is a general consensus among those studying the welfare of captive primates that social housing is the most effective means for promoting psychological well-being. It is well established that socially-housed rhesus macaques (Macaca mulatta)...
Pair housing for caged macaques in the laboratory generally allows unrestricted tactile contact but, less commonly, may involve limited contact via grooming-contact bars or perforated panels. The purpose of using this protected contact housing, which...
Lean management-based visual tools have been used to improve the quality of animal care associated with a complex research study involving immune-compromised cynomolgus monkeys (M. fascicularis) in various postsurgical recovery states. In order to effectively...
In the wild, patas monkeys (Erythrocebus patas) consume Acacia spp. gum for 20% of their active time. While providing gum-based enrichment to other gummivorous primates is not a unique idea, there have been no reports...
This review will examine how individual differences in temperament might affect, or be affected by, behavioral management practices for captive primates. Measuring temperament may help us predict the outcome of social introductions. It can also...
The eighth edition of The Guide for the Care and Use of Laboratory Animals establishes social housing as the "default" for social species including non-human primates. The advantages of social housing for primates have been...
A new application of a device enabling the long-term enteral administration of drugs or nutritional supplementation was developed for implementing in research entailing the use of macaques (Macaca fascicularis). After implanting a subcutaneous port, a...
