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

Using the system, we investigated the running behavior of 21 young C57BL/6 male mice. After the fast growth period, until 8 weeks of age, the mice ran 4 to 5 km/day at an average speed of 23 m/min, and spent...

More hippocampal neurons in adult mice living in an enriched environment

Mice reared in an environment enriched with running wheels, tunnels and toys possess more hippocampal neurons than litter mates reared in barren standard cages. It is likely that these extra neurons contribute to the enhanced performance in learning tasks showed...

Evaluation of objects for environmental enrichment of mice

Single-cage mice spent 3.58 min interacting with the marble, 50,16 min interacting with the tunnel, and 271.00 min interacting with the nestlet. Control animals spent a mean of 35 min digging in bedding, suggesting that bedding served as an important...

Effects of cage enrichment on territorial aggression and stress physiology in male laboratory mice

Findings suggest that keeping adult male mice in structured cages can result in increased aggression towards intruders, a change in the social organization, and altered endocrine states.

Age and weight at weaning affect corticosterone level and development of stereotypies in ICR-mice

Artificial weaning in laboratory mice elicits increased levels of exploratory and escape behaviour. Under barren housing conditions patterns of exploration and escape subsequently develop into stereotypic behaviour. .. Both plasma corticosterone levels 48 h after weaning and adult stereotypy levels...

Preferences for nesting material as environmental enrichment for laboratory mice

All [group-housed] mice showed a clear preference for cages with [paper] tissues or [paper] towels as compared to paper strips or no nesting material, and for cages with cotton string or wood-wool as compared to wood shavings or no nesting...
