Stereotypies in laboratory mice: Quantitative and qualitative description of the ontogeny of ‘wire-gnawing’ and ‘jumping’ in Zur:ICR and Zur:ICR nu mice

The ontogeny of two stereotypic patterns, wire-gnawing and jumping, was studied in 24 laboratory mice: six males and six females each of two closely related outbred strains, kept under standard housing conditions, a conventional albino strain (ICR) and a nude,...

Preference for different types of flooring in two rat strains

The rats showed a significant preference for the cages with wood shavings and paper bedding, both consisting of large particles. ... The cages with sawdust and wire mesh floor were relatively avoided. Rats slept in the cages with large-particles bedding,...

Environmental enrichment for laboratory mice: preferences and consequences

Current laboratory housing systems have mainly been developed on the basis of ergonomic and economic factors. These systems provide adequate, basic physiological requirements of animals, but only marginally fulfill other needs, such as the performance of natural behaviour or social...

Comparative studies on housing conditions

The presence of cage furniture and/or deep litter may increase aggression among group-housed male mice, though subordinates have a better chance of escaping injurious fights. Group-housed rats tend to play longer on grid floor, but when given the choice prefer...

Reorganising behaviour in laboratory mice with varying cost of access to resources

By using traverses of shallow water, the costs of gaining access to food [length of traverses], shelter, a conspecific, increased space, a running wheel, deep sawdust, or enrichment (e.g., balls, a variety of small objects) were increased for laboratory mice....

Preferences of laboratory mice for characteristics of soiling sites

These results show that the mice defecated in localized areas and preferred to defecate in areas containing sawdust [rather than on bare plastic floors]. These results support other evidence which indicates that conventional cage designs for mice do not provide...

Preferences of individually housed TO strain laboratory mice for loose substrate or tubes for sleeping

Individually housed mice preferred to sleep in sawdust [rather than pre-formed tubes] when this was available. The mice slept in the tubes only after the sawdust was removed. The animals showed no preference for shape, opacity or openness of the...

Laboratory mice persist in gaining access to resources: a method of assessing the importance of environmental features

By using traverses of shallow water in two experiments, it was determined how laboratory mice defended gaining access to feed, shelter, a conspecific or increased space (Experiment 1), and to feed, a running wheel, enrichments ('toys') or deep sawdust (Experiment...

Behaviour of rats in their home cages: daytime variations and effects of routine husbandry procedures analysed by time sampling techniques

Single-caged male rates were studied. The cleaning regime [cages cleaned out and fresh sawdust with shredded paper provided] appeared to have a greater effect on behaviour [increased defecation and activity] than did time of day and the effects of cleaning...
