Environmental enrichment for laboratory animals

Includes regulatory compliance, program development and management, common environmental enrichment strategies, program assessment and monitoring. A key component to the enrichment program development is the understanding of the natural behavior and habitat of each species housed in the animal facility....

Environmental enrichment rescues protetin deficits in a mouse model of Huntington’s disease, indicating a possible disease mechanism

These results suggest that environmental enrichment benefits animals at early stages of the disease by rescuing protein deficits, possibly through rescuing transcription or protein transport problems.

Housing conditions affect self-administration of anxiolytic by laboratory mice

Standard cages for laboratory rodents may induce greater anxiety than enriched cages. Enriched mice drank significantly less of the midazolam solution than the non-enriched mice, suggesting that the combined effect of more space and enrichment made the animals less anxious.

Mirrors as potential environmental enrichment for individually housed laboratory mice

The present study examined the influence of a mirror on the behaviour individually housed laboratory mice. Sixteen mice were placed into apparatus comprised of preference cages connected by a tunnel. A mirror was placed in one of the preference (mirror)...

Environmental enrichment: room for reduction? Alternatives to Laboratory Animals (ATLA) 32(Supplement 2), 69-71

Environmental enrichment strategies are usually regarded as refinement. However, when the welfare of animals is enhanced through successful enrichment programmes, a reduction in the number of animals needed can be expected, because fewer animals might be lost during the course...
