Abstract

Enriching the environments of groups of captive chimpanzees by providing a variety of attractive foods (fruit) does not seem to increase tension or lead to increased pre-feeding agonism. Managers should be encouraged to provide a varied diet reflecting the food preferences exhibited by chimpanzees in the wild. Results indicate enclosure size can also impact animal welfare as decreased space resulted in increased agonism regardless of season.
