Pair housing adult female rhesus macaques: Is it always the best option?

Cortisol levels between compatible pairs and individually caged animals revealed no significant difference. Cortisol levels had the tendency of being higher (p=0.09) in individually caged animals who had their partner removed for experimental purposes than in individually caged animals who...

Pair-housing macaques with biomedical implants: a safe and practical alternative to single-housing

Recognition of the importance of social interaction for primate well-being has led to new USDA guidelines recommending that animal facilities provide social enrichment for captive primates, as long as doing so does not endanger the animals or interfere with research...

Swimming pools provide additional socialization to group-housed male macaques

A group of five subadult male macaques [probably rhesus] adapted easily to a wading pool filled with about 30 cm deep water. The animals swam and dived with eyes open and played in the water.

Animal welfare and enrichment: A preference study in the common marmoset (Callithrix jacchus)

In general, the results showed that the monkeys choose much less than expected between fruits cut and presented as usual in an open dish and fruit inserted as a whole in a pointed branch. When choosing a particual enrichment, it...

Effects of positive reinforcement training on stereotypical behaviour in rhesus macaques

While the sample size it too low to make definitive conclusions, these data suggest that positive reinforcement training may [sic] be useful in reducing the incidence of stereotypic behaviour.
