To enrich or not to enrich: providing shelter does not complicate handling of laboratory mice

It is argued that when laboratory mice can routinely retreat in sheltering objects when humans are present, they do not habituate to humans and continue to shy away, thereby increasing the time needed for husbandry and testing procedures. ... We...

Refinement of routine procedures: Can environmental enrichment reduce the stress response of laboratory mice

Female mice housed in trios in enriched cages and handled daily reacted with less anxiety to procedures than female mice housed singly in barren cages and handled only when necessary.

Effect of environmental enrichment on the reproductive performance of FVB breeding mice

The results suggest that while the enrichment devices [transparent dome with or without activity wheel] .. provided for species-ypical behavior, their use is associated with longer inter-birth intervals and smaller litters in FVB breeding mice.

Effects of environmental enrichment on males of a docile inbred strain of mice

Environmental enrichment is intended to improve the welfare of laboratory animals. However, regarding male mice, numerous studies indicate an increase in aggressive behavior due to cage structuring. On the one hand, this might be a problem concerning animal welfare. On...

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.

Evaluation of cage micro-environment of mice housed on various types of bedding materials

A variety of environmental factors can affect the outcomes of studies using laboratory rodents. One such factor is bedding. Several new bedding materials and processing methods have been introduced to the market in recent years, but there are few reports...

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.
