Factors affecting aggression among females in captive groups of rhesus macaques (Macaca mulatta)

Captive groups of primates often exhibit higher rates of aggression than wild, free-ranging groups. It is important to determine which factors influence aggression in captivity because aggression, particularly intense aggression, can be harmful to animal health and well-being. In this...

Behavior of female pairs vary between protected contact and full contact pair housing in rhesus macaques but not longtailed macaques

However, tactile contact can also be provided by means of barred or perforated panels that permit physical interaction but prevent entry into pair-mates' cages. Behavioral outcomesmay differ between these housing configurations and between species. To explore the interaction between these...

Separating cage-mates temporarily ? A LAREF discussion

The question was asked: “Research protocols sometimes require that compatible macaque pairs be physically separated for a limited time period (e.g., controlled food-intake studies; sample collection from chair-restrained subjects). Obviously – and as documented in the literature – partner separation...

Socialization of adult male cynomolgus macaques: benefits vs

At Charles River Laboratories (Reno, NV), we have a high rate of success when socializing juvenile and sub-adult cynomolgus macaques (Macaca fascicularis). Until recently, we would rarely attempt to introduce adult males through progressive contact panels due to previous unsuccessful...

Temperament ratings of laboratory rhesus macaques (Macaca mulatta): Effects of cage level and room composition

Measures of temperament in nonhuman primates generally reflect interactions between inherent individual characteristics and environmental contexts, and they may be indicators of physical and psychological well-being. Heritable aspects of temperament have been identified, but it is useful to evaluate the...

Rearing condition can affect success in social groups of rhesus macaques

Forming successful groups of rhesus macaques (Macaca mulatta) can be challenging. Males in particular do not always get along, and some need to be permanently removed due to fighting and trauma. Early rearing condition may play a role in social...

Effectiveness of perforated plexiglass dividers as social grooming devices between neighboring, individually housed adult male Macaca fascicularis
