Influence of two different kinds of foraging devices on feeding behaviour of rhesus macaques (Macaca mulatta)

A foraging device fitted on the ceiling of the cage (H), and a foraging device fitted on the front of the cage (V) and filled with pellets were tested in 12 individually housed animals. The animals moved the pellets from...

Forming a bachelor group of long-tailed macaques (Macaca fascicularis)

The careful establishment of a compatible group of 24 male long-tailed macaques is described. It should be noted, at this point, that despite this aggressive establishment of a hierarchy associated with grouping, injuries were minor. (In fact, the worst injuries...

A simple ethological monitoring system to assess social stress in group-housed laboratory rhesus macaques

The increasing awareness of the importance of social housing of laboratory primates results in the establishment of group housing in many facilities. Our aim was to develop a set of manageable tools to allow continuous monitoring of social relations within...

Heart rate responses to social interactions in free-moving rhesus macaques: (Macaca mulatta): A pilot study

Heart rate telemetry was explored as a means to access animal emotion during social interactions under naturalistic conditions. Heart rates of 2 middle-ranking adult females living in a large group of rhesus macaques (Macaca mulatta) were recorded along with their...

Affiliative interactions between singly-housed rhesus macaques in adjacent unmodified cages

Both males and females interacted with neighbors with a mean frequency of three times per hour; affiliative behavior made up approximately 60% of male-male interactions and 90% of female-female interactions. ... The extent of both male-male and female-female affiliation, despite...

Effect of tryptophan treatment on self-biting andcentral nervous system serotonin metabolism in rhesus monkeys (Macaca mulatta)

Two studies were conducted to examine the effects of oral L-tryptophan (TRP) supplementation as a treatment for self-injurious behavior (SIB) and to investigate behavior and central serotonin turnover of male rhesus monkeys. In Study One, TRP was administered to seven...

Effects of chronic social separation on cardiovascular disease risk factors in female cynomolgus monkeys

A lack of social support is associated with increased risk of coronary heart disease morbidity and mortality in human beings. Similarly, chronic social separation (single cage housing) potentiates atherosclerosis in female monkeys. Heart rate and luteal phase plasma progesterone concentrations...
