Why do male ICR(CD-1) mice perform bar related (stereotypic) behaviour? Behavioural Processes 47, 95-111

Bar behaviour is likely to stem from a motivation to leave the cage.

Strain-specific effects of cage enrichment in male laboratory mice (Mus musculus)

The relationship between aggression, testosterone and 'enrichment' [clear Perspex tunnel and a small handful of shredded tissue] suggest that increasing complexity in laboratory cages may increase a naturally selected territorial response in some strains. ... Enrichment, as used in this...

Isolator rodent caging systems: a critical review

The past 15 years have brought remarkable changes to the way we house rodents used in research. These changes coincided and, to a great extent, were driven by a marked increase in the use of genetically engineered mice. Notable changes...

Practical rodent enrichment

We have designed and evaluated two forms of rodent enrichment: (1) Floor feeding, where in addition to the standard diet present in the cage hopper, other food is mixed into the cage substrate; (2) A cage insert, which incorporates a...

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...

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...

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...
