Social housing of rats: Life-span effects on reaction time, exploration, weight, and longevity

Sprague-Dawley rats were housed throughout their lives either in group cages or singly in standard laboratory cages. Locomotor activity was observed at selected ages and, in addition, operant conditioning procedures were used with an extensively trained subset of the animals...

The effect of conspecifics on corticoadrenal response of rats to a novel environment

The effect of housing conditions and the presence of a conspecific on corticoadrenal response to a novel environment was studied in male Sprague-Dawley rats. The response to a novel environment was the same in rats housed in groups and rats...

Corticoadrenal and behavioral response to open field in pairs of male rats either familiar or non-familiar to each other

The effect of the presence either of a familiar or non-familiar conspecific animal on serum corticosterone and some behavioral responses in the open field was studied in male Sprague-Dawley rats. Animals tested in presence of a familiar animal showed a...

Group or singly housed rats? In: Standards in Laboratory Animal Management

From the available data it is concluded that housing rats singly affects survival. In both sexes singly housed animals showed a markedly lower survival rate than group-housed animals. This effect became apparent when the animals reached the age of about...

Behavioural approaches to rodent management

Clear discussion of spatial needs to allow for basic, species-characteristic postures and behaviors. The use of the species ethogram when caging is designed means something more than enclosing a few vital function within a space designed for human convenience; it...
