Cage space requirements for non-human primates in the United States of America are less than those in European countries. Studies in support of the assumption that the US legal minimum cage size provides adequate space...
Enrichment techniques designed to encourage captive primates to spend more species-appropriate amounts of time in foraging behaviours have been successful. The present study measured the behavioural effects of four feeding enhancements: two devices (mats and...
According to the Swiss Animal Welfare Legislation, the minimal enclosure area for macaques of the size of rhesus or cynomolgus monkeys for experimental purposes is 15 cubic meters. In such an enclosure up to 5...
Caretakers should seek knowledge of the natural lifestyles of the primates in their charge, and attempt to reproduce in the captive environment the salient aspects of the natural habitats that are biologically relevant to the...
We investigated pair housing of adult long-tailed macaques (Macaca fascicularis) by using widely spaced, vertical "grooming-contact" (G-C) bars that allow physical contact but prevent pursuit by one animal into the other's cage. Cages with G-C...
Results suggest a preference for horizontal furnishings above the enclosure floor. Adults infrequently used 'moving' furnishings (e.g., swinging ropes, hanging tubes, etc...) and seemed to prefer 'stable' horizontal furnishings (e.g., benches, logs) above the enclosure...
Brief but very useful guidelines of how an enrichment program can most effectively be developed and implemented. Care and research staff ideas are well-thought out prior to use of any new devices, and all staff...
The purpose of this study is to consider space use patterns of a single group of captive chimpanzees (Pan troglodytes) housed in an indoor exhibit at the Cleveland Metroparks Zoo. This report summarizes results from...
Because of the influence in behaviour, we can say that visitors are a kind of environmental enrichment. .... Sometimes visitors have a negative effect (increase of aggressive behaviour, begging for food) and in some cases...
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...
