At Charles River Laboratories, we are committed to ensuring all animals have the highest level of care and welfare. To this end, our social housing program includes placing all nonhuman primates in pairs or groups...
Medical care of nonhuman primates in a laboratory setting can be challenging due to the safety concerns inherent in handling conscious animals. A mature, adult male cynomolgus macaque presented with a chronic foot condition that...
Visual barriers have been shown to be valuable environmental components of nonhuman primate housing to break visual contact between conspecifics as well as between primates and their human keepers. The effect of visual barriers can...
In a biomedical research environment, research or management procedures may render continuous full contact pairing of rhesus macaques (Macaca mulatta) unfeasible. This study aimed to determine whether separation on a frequent basis or housing in...
Pairing laboratory macaques is a high priority goal for many behavioral management programs. There are numerous methodological differences in introduction procedures across facilities, including the intermediate stages used between single housing and full contact. A...
In the world of enrichment, ideas can be limitless. Sometimes, you just have to think outside the box... or in this case, "inside the box"! Who doesn't love a present with the colorful exterior and...
The influence of several factors on abnormal behaviour was investigated in 46 singly housed sooty mangabeys (Cercocebus atys) (eight nursery-reared, 38 mother-reared), including self-injurious, self-directed, stereotypic locomotion, and faeces/urine-related behaviours (SIB, SDB, SL, FUR, respectively)...
The goal of this project was to evaluate the efficacy of a porch in decreasing feces painting in captive rhesus macaques. The porch is a small extension that is hung on the outside of a...
