Impact of home cage alterations on aggression in mice

PVC straight pipes, plumbing elbows and T pipes, and shreddible nesting squares were evaluated. Nesting squares appear to be the most effective enrichment object for reducing the incidence of aggression in group-housed male mice.

Aspen wood-wool is preferred as a resting place, but does not affect intracage fighting in male BALB/c and C57BL/6J mice

The nesting material [aspen wood-wool] used in this study did not cause any adverse effects on the animals, as determined by both behavioural and physiological observations. On the other hand, it might have a positive value for the animals; the...

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.

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...

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...

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]

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...

Improvements in transgenic animal husbandry and welfare: Provision of exercise wheels for group housed mice

The wheels are in almost constant use. The introduction of wheels therefore led to a cessation of the stereotypic cage climbing behaviour and the gnawing of food. However, there is some controversy as to whether wheel running is in itself...
