Social and husbandry factors affecting the prevalence and severity of barbering (‘whisker trimming’) by laboratory mice

Barbering was found to be related to ... cage design, cage location, cagemate relatedness, and the presence of other barbers in the cage [social facilitiation]. .. The relative dominance score of a mouse within its cage was unrelated to barbering,...

Stress response in mice to a stressful situation experienced by another cage mate

We have just finished a study of the effects on cage mates when balb/c mice are handled/weighed or subjected to 1 hour restraint stress and then returned to the cage. We did this once daily for 14 days. The cage...

From house mouse to mouse house: the behavioural biology of free-living Mus musculus and its implications in the laboratory

We review research and pest control literatures on the free-living house mouse (Mus musculus), analysing its sensory world, developmental processes and behaviour to suggest how laboratory environments might affect mouse welfare, normalcy, test design, and behaviour.

Effect of conditioning on the increase of heart rate and body temperature provoked by handling in the mouse

Handling and restraint of mice are common procedures in the laboratory animal house. The purpose of the present study was to investigate whether conditioning of mice with an acoustic stimulus (10kHz, 60dB), can reduce the stress effects of these routine...

Environmental enrichment options for laboratory rats and mice

Environmental enrichment is the alteration of animals' microenvironment to provide them with the opportunity to perfrom species-specific behaviors that we perceive as positive, while reducing abnormal behaviors. [p. 39] Several interesting products are now available commercially, and I will review...

Behavioural activity of laboratory mice in standard and furnished cages with a running wheel

Stereotypies such as bar circling, jumping and bar wheeling were only seen in the standard cages. More than half of the exploration/locomotion in furnished cages was wheel running, indicating that the running wheel is an essential component if an increase...

Effect of pre- and postweaning housing on the behaviour of laboratory mice

It took longer to catch mice in [with nestbox, tissue nesting material, chewblock and carboard tube] Furnished (10. +/-0.53 s) than in Standard (8.7 +/- 0.36 s) cages.

Environmental enrichment results in cortical and subcortical changes in levels of synaptophysin and PSD-95 proteins

Experience-dependent plasticity is thought to involve selective change in pre-existing brain circuits, involving synaptic plasticity. One model for looking at experience-dependent plasticity is environmental enrichment (EE), where animals are exposed to a complex novel environment. Previous studies using electron microscopy...

Providing shelter does not complicate manipulation in two mouse strains

Enrichment in the form of sheltering objects [PVC tubes] does not complicate catching or handling mice and does not interfere with management or cost of laboratory animals. FVB males should not be kept together unless such enrichment is provided.
