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: practical applications

A general discussion. Mice show clear choices for cage enrichment, and animals from enrichment environments seem to be better adapted to experimental conditions.

Environmental enrichment, immunocompetence, and resistance to Babesia microti in male mice

Groups of male CFLP mice housed in cages furnished with shelves and nestboxes showed increased aggression and reduced resistance to an experimental infection of Babesia microti when compared with groups in unfurnished cages. Both a bystander measure of immunocompetence (serum...

Rodent enrichment devices – evaluation of preference and efficacy

The mice preferred cotton nestles and cardboard rolls over wooden block and commercial toys. When animals wearing wound clips were exposed to the preferred enrichment, premature wound clip removal decreased, suggesting a positive effect of enrichment on the psychological well-being...

Transgenic Animals

The creation of transgenic animals is resulting in a shift from the use of higher order species to lower order species, and is also affecting the numbers of animals used. An example of the replacement of higher species by lower...

Environmental enrichment: does it reduce barbering in mice?

One of the problems in maintaining group-housed mice is barbering one or more mice chewing (barbering) the fur and whiskers of other mice. A group of 300 mice of both sexes, which are being studied over their lifetime, were housed...

Observations on the prevalence of nest-building in non-breeding TO strain mice and their use of two nesting materials

Within 2-3 min of the nesting materials being placed in the cages, many mice had pulled the paper towel from the pot into the main cage, investigated, chewed and manipulated the sheet. ... Thirty-six of the mice constructed nests during...

Training a large number of laboratory mice using running wheel and analyzing running behavior by use of a compter-assisted system
