Effect of group housing and oral corticosterone administration on weight gain and locomotor development in neonatal rats

The stress response of rats induced by transfer from communal housing to single housing prior to parturition has a negative influence of the offspring. This is manifested by slower growth rate and a retardation in locomotor development.

Laboratory Animal Management: Rodents

Studies have found that compatible social groups of rodents do not use all the available [barren!] space recommended in current guidelines and probably do not require it for well-being (White, 1990; White et al., 1989). .. Even if individually housed,...

Caloric density affects food hoarding and intake by Siberian hamsters

Siberian hamsters respond to food deprivation or restriction by increasing their food hoarding and do so proportionately to the degree of body mass (fat) loss. These data suggest that Siberian hamsters integrate their internally stored energy as body fat with...

The use of a novel operant test to determine the strength of preference for flooring in laboratory rats

Both studies indicated that rats prefer to rest on solid floor. The experiments reported in this paper also show that rats are prepared to make considerable efforts to reach a solid floor when they wish to rest. Thus there is...

Food deprivation-induced increases in hoarding by Siberian hamsters are not photoperiod-dependent

Siberian hamsters increase food hoarding in response to chronic food restriction and food deprivation, conditions that lead to a loss of body mass and fat. Therefore, the first purpose of the present experiments was to test further the effects of...

Effect of cage size on the ontogeny of stereotyped behaviour in gerbils

Gerbils develop stereotyped digging independent of cage space, but probably dependent of lack of adequate stimuli for digging.

Effect of environmental enrichment and housing density on immune system reactivity to acute exercise stress

Keeping mice in enriched cages rather than barren standard cages seems to enhance immune function. Environmentally enriched mice behave immunologically much like nonstressed animals. Animals in enriched environment showed a less variable, better regulated immune response.

Environmental enrichment: practical applications

A general discussion. Mice show clear choices for cage enrichment, and animals from enrichment environments seem to be better adapted to experimental conditions.
