Enhanced physical environment in single-housed macaques: A long-term usage profile of cage extensions

Social housing is always preferred in the research environment; however, single housing is sometimes necessitated by scientific objectives or social incompatibility. In these cases, other environmental enhancements are developed to provide indirect social interactions. We developed a novel cage extension...

Providing feeding enrichment by hand mitigates anxiety among laboratory-housed rhesus macaques (Macaca mulatta)

Some husbandry procedures may be perceived as aversive by cage‐housed rhesus macaques. We assessed whether providing feeding enrichment by hand as opposed to placing it on a caging surface decreases anxiety responses to daily husbandry activities. Eleven adult males and...

A successful strategy for social housing adult male cynomolgus macaques in triads

At Charles River, we are committed to ensuring all animals have the highest level of care and welfare. For juvenile, subadult and adult female cynomolgus macaques (Macaca fascicularis), we have a near 100% success rate for social housing. Sexually mature...

Behavioral predictors of successful pairing of rhesus macaques (Macaca mulatta) at the visual contact phase of social introduction

Identification of behaviors early in the process of rhesus macaque social introductions that might predict social housing success would allow primate managers to best allocate resources and minimize animal stress by aborting introductions unlikely to lead to successful pairings. We...

Dams’ social behaviour and long-term cortisol profiles in response to their infants being nursery-reared

The influence of early rearing experiences on infants' social and neuroendocrine development is well characterized. However, little is known about the effects of nursery rearing (NR) on the infants' mothers. Such information is important in welfare considerations. In a two‐part...

Rhesus macaques (Macaca mulatta) displaying self-injurious behavior show more sleep disruption than controls

Self-injurious behavior (SIB) is a pathology observed in both humans and animals. In humans, SIB has been linked to various mental health conditions that are also associated with significant sleep disruption. In rhesus macaques, SIB consists of self-directed biting which...

A protocol for training group-housed rhesus macaques (Macaca mulatta) to cooperate with husbandry and research procedures using positive reinforcement

There has been increased recognition of the 3Rs in laboratory animal management over the last decade, including improvements in animal handling and housing. For example, positive reinforcement is now more widely used to encourage primates to cooperate with husbandry procedures,...

A cross-species comparison of abnormal behavior in three species of singly-housed old world monkeys

Abnormal behavior occurs in a number of captive nonhuman primate species and is often used as an indicator of welfare. However, reported levels of abnormal behavior often vary across species, making general welfare judgments difficult. The purpose of this study...

Behavioral and cortisol responses of adult marmoset monkeys (Callithrix penicillata) to different home-cage social disruption intervals

Social separation is an increasingly used strategy to experimentally assess psychogenic stress in nonhuman primates, yet it is also inherently required for captive management. Surprisingly, little is known on the effects of an individual left alone in a highly familiar...

Stone handling, an object play behaviour in macaques: Welfare and neurological health implications of a bio-culturally driven tradition

Object play in primates is viewed as generally having no immediate functional purpose, limited for the most part to immature individuals. At the proximate level, the occurrence of object play in immatures is regarded as being intrinsically self-rewarding, with the...
