Isosexual pair-housing of ten female and six male previously single-caged adult stump-tailed macaques (Macaca arctoides) was attempted. Partners were introduced to each other following the establishment of rank relationships during a three-day non-contact familiarization period...
With some professional expertise and goodwill, there should be no real need to resort to forceful restraint when doing research with nonhuman primates.
For captive primates, environmental enrichment may improve psychological well-being, as indicated by changes in the frequency of species-typical and abnormal behaviours. The effects of enrichment on physical well-being have also been examined, but little attention...
The present article represents a consensus view of the appropriate utilization of chimpanzees in AIDS research arrived at as a result of a meeting of a group of scientists involved in AIDS research with chimpanzees...
The proximity of individual members of three family groups of marmosets was measured to two sources of food namely, on the introduction of their normal daily ration (baseline behaviour) as well as to a previously...
Environmental improvements include construction of large indoor cages that allow pairing of experimental animals, a grass-covered 'playground' for breeding chimpanzee groups, and indoor/outdoor group housing for 'retired' experimental animals. In addition, we provide toys, perches...
Food cannot be collected without effort, but must be plucked [from the net] item by item, resulting in an increase of feeding time. The net is attached to the top of the cage.
A review of the scientific literature gives evidence that transferring previously single-caged adult macaques to permanent compatible pair-housing arrangements (isosexual pairs, adult/infant pairs) is associated with less risk of injury and morbidity than transferring them...
Published information provides scientific evidence that traditional, involuntary restraint techniques of research non-human primates are intrinsically a source of distress resulting from fear. It has been documented that common methods of enforced restraint result in...
Our laboratory, a short time after the introduction of woodchip, became infested with domestic mice. ... We decided to adequate the original idea changing woodchip with argilla espansa ... a material that is used in...
