Activation of aryl hydrocarbon receptor signaling by cotton balls used for environmental enrichment

Dioxins are nearly ubiquitous environmental contaminants that are produced as byproducts during industrial processes, including the bleaching of paper and textiles. Contamination of animal bedding material with dioxins has been a concern for both laboratory and farm animals. The objective...

Effects of environmental enrichment on the amyotrophic lateral sclerois mouse model

The manner in which an animal's environment is furnished may have significant implications for animal welfare as well as research outcomes. We evaluated four different housing conditions to determine the effects of what has been considered standard rodent enrichment and...

Effects of cage-change frequency and bedding volume on mice and their microenvironment

The frequency at which mouse cages are changed has important implications for the animals, animal care personnel, and facility managers. The objective of this study was to determine how bedding volume and the interval between changes affect microenvironmental conditions, health,...

Investigating enrichment preferences for CD-1 mice housed in wire-bottom cages

Mice rarely slept in the houses and chewed toys initially with usage dropping off after a few days. Mice given nesting materials tended to stay in their nests. Many were found asleep at the daily clinical observations time and were...

Construction noise decreases reproductive efficiency in mice

Excessive noise is well known to impair rodent health. To better understand the effect of construction noise and to establish effective noise limits during a planned expansion of our vivarium, we analyzed the effects of construction noise on mouse gestation...

The response of C57BL/6J and BALB/cJ mice to increased housing density

Increased numbers of mice housed per cage (that is, increased housing density) is seen as 1 way to reduce the costs of conducting biomedical research. Current empirically derived guidelines are based on the area provided per mouse depending on body...

There’s a rat in my room! Now what? Mice show now chronic physiological response to the presence of rats

The study concluded that housing rats and mice in the same room is at least less disturbing than cage cleaning.

Organic wheatgrass as environmental enrichment

Environmental enrichment must be provided for the various animal species that are housed in laboratory animal facilities. Wheatgrass can be used as a natural form of enrichment that requires minimal preparation and effort. Wheatgrass is appropriate enrichment for cats, rabbits,...
