Assessment of the use of two commercially available environmental enrichments by laboratory mice by preference testing

All three strains of mice showed a significant preference for the paper box. The paper box was much lighter [20 g] than the plastic box [95 g]. This allowed the mice to move the paper box around, manipulate it and...

Coping with aggression in group-housed male mice

Groups of three males have been found to show the least aggression because the dominance hierarchy is more stable than in larger groups. Pair housing can increase aggression and is more stressful to the subordinate because he will not receive...

Impact of environmental enrichment in mice

The result of this study suggests that values of body weight, haematological variables .... were not significantly influenced by our enrichment design [nestbox plus climbing structure], but that enrichment seemed [sic] to have effects on the variation and the strain...

Effects of housing density and cage floor space on three strains of young adult inbred mice

Some recommendations in the Guide for the Care and Use of Laboratory Animals (the Guide) are based on best professional judgment. Our current efforts are directed toward replacement with data-driven standards. We demonstrated earlier that young adult C57BL/6J mice could...

Modifications to husbandry and housing conditions of laboratory rodents for improved well-being

A review of the literature shows that a consensus on the definition of changes constituting environmental enrichment has yet to be reached. For this reason, the results of studies on the effects of rodent enrichment are inconsistent. In many cases,...

Mice selectively bred for open-field thigmotaxis: life span and stability of the selction traint

THE OPEN-FIELD (OF) TEST, originally developed by Hall (Hall & Ballachey, 1932), is one of the most widely used methods in the study of emotionality in rodents. The test is conducted in an enclosed open area in which the animal...

A study in refining husbandry techniques for the in-house breeding of rats and mice

Because of the nature of genetically altered animals the probability tht they are deliberately or unintentionally altered in their morphology, physiology and or behaviour can lead to the need to make changes in how we maintain each strain. We are...

Effects of cage size and environmental enrichment on organ weight and leukocyte distribution in C57BL/6, BALB/c and CD-1 mice

Female mice from 3 strains were housed in polycarbonate cages each containing 4 same-strain mice under one of the following conditions: small (58cm2 per mouse) unenriched cage, small enriched cage, medium (96.8 cm2 per mouse) unenriched cage, medium enriched cage,...

Use of discarded equipment for cost-effective mouse enrichment

Damaged water bottles waiting to be discarded were modified to create mouse houses. An opening was made in the bottle, making sure there were no rough edges.
