Effects of caging type and animal source on the development of foot lesions in Sprague Dawley rats (Rattus norvegicus)

Noteworthy abnormalities of the plantar surface of the hind foot (i.e., ulcers or nodular swellings) were more common in heavierrats than in lighter animals of the same sex (but different source), and abnormalities were more common in rats housed in...

Therepeutic effects of environmental enrichment on cognitive function and tissue integrity following severe traumatic brain injury in rats

These results indicate that noninvasive environmental stimulation is beneficial in attenuating cognitive deficits and preserving tissue integrity in a TBI model which causes cerebral contusion and cell death.

Environmental enrichment for laboratory rats: A review

In the laboratory, rats have been found to benefit from social contact, shelters, nesting material, objects for gnawing and large, complex cages whilst the provision of toys or open space is largely unsuccessful.

The cage preferences of laboratory rats

The rats did not show significant preferences for most of the options [e.g., toys] over an empty cage. The exceptions were shredded paper, a nesting box and a semi-enriched condition incorporating a range of modifications.

Revolutionary Science: An improved running wheel for hamsters and mice

Golden hamsters and mice ran more in wheels with the floor covered with plastic mesh than in wheels with the usual metal rods. Small diameter wheels were preferred less than standard 17.5-cm wheels.

Modulation of aggression in male mice – Influence of group size and cage size

It is concluded that aggressive behaviour in group-housed male BALB/c mice is best prevented by housing the animals in small groups of three animals, while decreasing floor size per animal may be used as a temporary solution to decrease high...

Male Management – Coping With Aggression Problems in Male Laboratory Mice (Doctoral Thesis)

The purpose of this thesis was to find practical solutions for coping with excessive aggressive behaviour in male laboratory mice. .. The proximity of another male is preferred to individual housing, irrespectively of dominance status, kinship or familiarity. ... Male...

Do male mice prefer or avoid each other’s company? Influence of hierarchy, kinship, and familiarity

Experiments that allowed male mice with different histories to choose either an inhabited or an empty cage have shown that the mice preferred the proximity [separated by wire mesh or Perspex wall with holes] of another male over individual housing....

The effects of regrouping on the growth curve of male Sprague Dawley rats

Rats are usually regrouped on a weekly basis without regard for source, so that the animals in a cage fall within a narrow weight range. ... There were no significant differences of growth rate between the rats in the stable...
