The effect of cage size and enrichment on core temperature and febrile response of the golden hamster

Male golden hamsters were studied. The results indicate that housing in small cages induce chronic stress which obviously affects thermoregulation. .... The comparison of the mean values between different sizes of standard cages and between standard and enriched cages of...

Housing and welfare in laboratory rats: effects of cage stocking density and behavioural predictors of welfare

Using male and female Alderley Park (Wistar-derived) rats housed in single-sex groups in standard laboratory cages, we looked at the effect of group size (one, three, five or eight) on competitive behaviour and time budgeting (initial and longer term), changes...

Inbreeding and its consequences for social beahviour, housing and welfare in mice: A case of He ain’t smelly, he’s my brother’?

As individuals of an inbred strain are genetically homozygous .. it was hypothesised that olfactory chemosignals of individuals may be the same, thus it may not be possible for mice to recognise individuals. .. Results indicated that outbred mice recognised...

A rodent model of spontaneous stereotypy: initial characterization of development, environmental, and neurobiological factors

Preliminary observations suggest that increasing environmental complexity is associated with decreased stereotypy. Stereotypies are patterns of motor behavior that are repetitive, excessive, topographically invariant, and that lack any obvious function or purpose. [p. 355]

In summary, solid-bottomed cages with bedding material are preferable; in general, group housing is preferable to individual caging so long as the groups are formed early in life, are stable and harmonious. There should be room for hiding and escaping...

Evaluation of environmental enrichment for laboratory mice

Providing a cage with a preferred nesting material can be a relatively simple method to contribute to the well-being of laboratory mice, without jeopardizing the outcome of experiments. Thus, there seems to be no good reason to deprive laboratory mice...

Behavioural and glial changes in old rats following environmental enrichment

Results confirm the aging-related acquisition and memory deficit. EC reduced the slowness of acquisition, reversed the short-term memory deficit and promoted the retention of the short signal (choose short effect).

Housing familiar male wildtype rats together reduces the long-term adverse behavioural and physiological effects of social defeat

Social stress in rats is known to induce long-lasting, adverse changes in behaviour and physiology, which seem to resemble certain human psychopathologies, such as depression and anxiety. The present experiment was designed to assess the influence of individual or group...
