Addressing the Environmental Enrichment Needs of Mice: Thinking Outside the Cage

The challenge of providing effective enrichment to mice is to ensure that it allows for normal behavioral opportunities. Studies are ongoing to further identify the behavioral needs of mice in the laboratory environment. Many innovative choices of environmental enrichment devices...

Quality of plasma sampled by different methods for multiple blood sampling in mice

For oral glucose tolerance test (OGTT) in mice, multiple blood samples need to be taken within a few hours from conscious mice. Today, a number of essential parameters may be analysed on very small amounts of plasma, thus reducing the...

Effects of cage size and enrichment on reproductive performance and behavior in C57BL/6Tac mice

While cage size did not affect reproductive performance, enrichment (regardless of cage size) did signficicantly benefit reproductive performance; pups from non-enriched cages weighed less and fewer survived to weaning age than pups from enriched cages.

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...
