Environmental enrichment for laboratory rodents and rabbits: Requirements of rodents, rabbits, and research

Environmental conditions such as housing and husbandry have a major impact on the laboratory animal throughout its life and will thereby influence the outcome of animal experiments. However, housing systems for laboratory animals have often been designed on the basis...

Passive responses of young guinea pigs during exposure to a novel environment: Influences of social partners and age

Guinea pig pups exhibit a two-stage, active/passive response during isolation in a novel environment that resembles the “protest” and “despair” stages observed in some species of primates. The present study examined social and developmental influences on the expression of the...

Social environment determines the long-term effects of social defeat

A single social defeat by a dominant conspecific induces long-term changes in several physiological and behavioral parameters in rats. These changes may represent an increased vulnerability to subsequent stress and stress-related pathology. Environmental factors, in particular possibilities for social interactions,...

Rx for mice: Take enrichment and call me in the morning

In a first phase, the effectiveness of several enrichment devices was evaluated: flavored nylon chew bones, colored tunnels, igloo shaped houses, and a life-sized rubber mouse. Mice, whether alone or in a group, had constant interaction with the houses.... I...
