Refining the traditional housing and handling of laboratory rhesus macaques improves scientific methodology

A monkey housed in an empty cage, however, is literally a behavioral cripple because s/he is chronically deprived of appropriate stimuli for the expression of species-typical behavior patterns. It is difficult to know objectively if a monkey experiences boredom when...

Lighting conditions for laboratory monkeys: Are they adequate? Animal Welfare Information Center (AWIC) Newsletter 8(2), 3-6

The prevailing monkey cage arrangement makes adequate, that is uniform, illumination impossible, because the cages of upper-rows block the light from entering the cages of lower-rows. Caging all animals at the same level of the room is the only solution...

Behavioral responses of Barbary macaques (Macaca sylvanus) to variations in environmental conditions in Algeria

Annual time budgets of Barbary macaques did not differ noticeably between the two sites investigated. Monkeys spent around 5 h resting (more than 35% of the day) and only 1.3-1.5 h in social activities in a mean day length of...

Abnormal behavior in a captive chimpanzee colony

The purpose of this study was to link abnormal behaviors often expressed by chimpanzees living in captive environments to factors related to their care and housing. Individuals who had spent more time with their mothers had less abnormal behavior. Access...

Effective and inexpensive environmental enrichment for nonhuman primates

An effective enrichment program will produce contented primates -- human and nonhuman alike -- and will improve the quality of the data collected because contented animals are more species-typical and show no psychological or physiological abnormalities. Hence, environmental enrichment is...
