Catering to caterrhines: Food enrichment at the University of Washington’s Regional Primate Research Center

As simple and relatively inexpensive form of enrichment each animal received a treat (e.g., fruit, vegetable, exposure to foraging device) on 4 days per week. This costs about $0.50 per macaque or baboon per week.

Outdoor access: The behavioral benefits to chimpanzees

When compared to the results of ameliorative environmental enrichment techniques furnished to the indoor-housed subjects, the small outdoor groups of [two or three] chimpanzees showed broader and more dramatic improvements in well-being. Animals with outdoor access showed significantly less abnormal...

Requirements of biomedical research in terms of housing and husbandry for non-human primates: Pharmacology & Toxicology

The objective of toxicology and pharmacology studies is to detect change or variation from normal and to interpret the significance of such change, with the intention of assessing risk to man. With non-human primates (NHPs) detection of change related to...
