Effect of environmental enrichment and housing density on immune system reactivity to acute exercise stress

Keeping mice in enriched cages rather than barren standard cages seems to enhance immune function. Environmentally enriched mice behave immunologically much like nonstressed animals. Animals in enriched environment showed a less variable, better regulated immune response.

Environmental enrichment for laboratory mice: preferences and consequences

Current laboratory housing systems have mainly been developed on the basis of ergonomic and economic factors. These systems provide adequate, basic physiological requirements of animals, but only marginally fulfill other needs, such as the performance of natural behaviour or social...

Laboratory mice persist in gaining access to resources: a method of assessing the importance of environmental features

By using traverses of shallow water in two experiments, it was determined how laboratory mice defended gaining access to feed, shelter, a conspecific or increased space (Experiment 1), and to feed, a running wheel, enrichments ('toys') or deep sawdust (Experiment...

Effects of physical and social environmental enrichment on the behavior of juvenile chimpanzees

No behavioral differences (interaction with physical environment, locomotion, rocking) were found between pair-housed and single-housed animals.

Goldfish as enrichment for singly housed chimpanzees

The aquarium [with a single goldfish] was attached to the outside of the chimpanzee's cage ... so that the single-caged subject was able to touch the aquarium but not the fish itself. At the conclusion of this study the authors...

Space utilization by captive-born baboons (Papio sp.) before and after provision of structural enrichment

Eight baboon groups (Papio sp.) were observed for over one hundred scan samples both before and after the provision of structural enrichment. Additions to their home-cage included a galvanized ladder suspended horizontally by chains and a plastic drum hung from...
