The effects of enrichment with music or colorful light on the welfare of restrained mice

Objective: To investigate the positive effects of four different forms of environmental enrichment on the welfare of mice subjected to restraint stress with the purpose of screening suitable enrichment. Method: Mice undergoing poor welfare due to repeated restraint were kept...

A renewed look at laboratory rodent housing and management

In this article, recent publications are examined to determine the potential impact of new scientific evidence on current practices for the housing and care of laboratory rodents. The discussion points out recent advances in technology and new knowledge of the...

Environmental enrichment:Running wheels; burrows for rats and gerbils

Running wheels provide suitable enrichment rodents.The need to dig a burrow is probably not as strong in rats as it seems to be in mice. In sharp contrast to rats - who are very curious - mice are reluctant to...

Environmental enrichment: Shelter and nesting material for rodents and rabbits; bedding for rodents

The needs for a shelter and nesting material of mice and rats are quite different. Building their own nests is almost a must for mice, and the nest will then also be used as a retreat. For rats, access to...

Capture of group-housed animals

Rats, mice and rabbits can be induced to come forward and be picked up by luring them with a food reward. Guinea pigs tend to be more timid but will run into a shelter in which they can then be...

Environmental enrichment effects on development of retinal ganglion cell dendritic stratification require retinal BDNF

A well-known developmental event of retinal maturation is the progressive segregation of retinal ganglion cell (RGC) dendrites into a and b sublaminae of the inner plexiform layer (IPL), a morphological rearrangement crucial for the emergence of the ON and OFF...

Making use of the stress buffering influence of a companion: Post-operative care

We have mice who are recovering from telemetry-implantation while being housed either alone or in pairs. With several years of experience with this surgery, we now are pretty sure that socially housed mice feel better than individually housed mice.I can...

Feeding enrichment for mice, rats, guinea pigs, rabbits, cats and sheep

Feeding enrichment is a practical option for animals kept in research laboratories. The regular provision of thoroughly cleaned, whole fruits and vegetables and of seeds scattered on woodchips or corncob bedding is probably the easiest yet most effective way to...

The effect of preweaning and postweaning housing on the behaviour of the laboratory mouse (Mus musculus)

In this experiment, 64 pairs of animals of the strain C57BL/6J were used. Half of the animals were born and reared until weaning in standard cages and the other half in cages twice the size of the standard and furnished...

Cage cleaning regimes and the welfare of laboratory mice (Mus musculus)

This research asks if we can improve the psychological well-being of mice by reducing cage-cleaning frequency, and without adversely affecting their health.
