Behavioral evaluation of spatially enhanced caging for laboratory rats at high density

The L-shaped partitions of the HP [high perimeter] allowed the rats added perimeter area fro tactile retreat and wall contact. These added perimeters also increased the use of the center of the cage.

Preferences of mice and rats for types of bedding material

The results seem to indicate that size and manipulability are among the main determinants of the appreciation of bedding particles by laboratory mice and rats, and larger particles are preferred. .. In the test system with two test cages, [aspen]...

Environment, social interaction, and physical activity as determinants of functional outcome after cerebral infarction in the rat

Thus, social interaction was superior to wheel-running but an enriched environment allowing free physical activity combined with social interaction resulted in the best [motor] performance.

Environmental influence on outcome after experimental brain infarction

After permanent ligation of the middle cerebral artery the motor function of rats housed in an enriched environment, i.e. cages with opportunities for various activities.. is significantly better than in rats housed in individual cages. Preliminary studies suggest that social...

Housing and welfare in laboratory rats: time-budgeting and pathophysiology in single-sex groups

Alderley Park (Wistar-derived) rats, Rattus norvegicus, were maintained in single-sex groups of eight for 9 weeks under open-room conditions. Both sexes could be categorized into more or less discrete social classes based on the directionality of aggression within dyads. The...

Exposure to environmental complexity promotes recovery of cognitive function after traumatic brain injury

The improved performance of injured rats recovering in the enriched environment occurred in the absence of environmentally induced alterations in brain weight. These results indicate that exposure to environmental complexity enhances recovery of cognitive function after TBI [traumatic brain injury].

Preference of laboratory rats for potentially enriching stimulus objects

Group-housed rats showed no preference for objects such as pipes and partitions but did show reliable preferences for spending time with some, but not all chewable objects. A block of wood predrilled with holes was the most attractive object.
