Environmental Enrichment for Nonhuman Primates (2004)

University of Michigan, A. A. M.

Abstract

This document outlines the Primate Environmental Enrichment Program (PEEP) developed for the University fo Michigan. The program is designed to promote the psychological well-being of nonhuman primates (NHP) used in research and to provide opportunities for NHPs to engage in noninjurious species-typical activities. The program is designed to comply with all regulations presented in the Animal Welfare Regulations as a result of the 1991 amended version of the Animal Welfare Act (9 CFR 3.81).When the temperament of individual animals and the nature of the research allows, social species should be housed in social groups.3.2. If animals cannot be housed in larger groups due to medical or research-related issues (see 3.3 below), animals should be pair-housed.If an animal cannot be pair-housed due to UCUCA-approved research-related issues, additional provisions must be made to allow for the social needs of the animal. These include the following:3.4.1. The ability to see other animals of the same species. This can be accomplished by positioning cages such that animals can see each other; providing mirrors that can be manipulated in multiple directions; and with appropriate cages, placing a clear partition between cages. However, regardless of which method is used, all animals should have the ability to hide from the view of other animals.Perches must be provided within the primary enclosure of all NHPs.
