Tilly, S.-L. C., Dallaire, J., Mason, G. J. 2010. Middle-aged mice with enrichment-resistant stereotypic behaviour show reduced motivation for enrichment. Animal Behaviour 80(3), 363-373.

For captive animals, living in barren conditions leads to stereotypic behaviour that is hard to alleviate using environmental enrichment. This resistance to enrichment is often explained via mechanisms that decouple abnormal behaviour from current welfare...

Õkva, K., Nevalainen, T., Mauranen, K. et al. 2010. The effect of three different items of cage furniture on the behaviour of male C57BL/6J mice in the plus-maze test. Animal Welfare 19(4), 401-409.

The aim of this study was to assess the effects of specific regimens of enrichment on the behaviour of C57BL/6J mice in the elevated plus-maze test (EPM). A total of 192 male C57BL/6J mice were...

Aasland, K. E., Skjerve, E., Smith, A. J. 2010. Quality of blood samples from the saphenous vein compared with the tail vein during multiple blood sampling of mice. Laboratory Animals 44(1), 25-29.

A large number of methods for obtaining blood from mice have been published. In our facility, saphenous venepuncture is considered the method of choice for bleeding mice and is believed to have a number of...

Araki, A. 2010. Using environmental enrichment to reduce fighting in mice. Tech Talk [The Newsletter for Laboratory Animal Science Technicians] 15(4), 6.

A colony of mice (base strain C57Bl6) was transferred to Oregon State University. Fighting was observed in six cages of males (2 to 5 mice per cage) at cage change, but not during daily checks...

Baran, S. W., Froberg-Fejko, K., Lecker, J. et al. 2010. Post-surgical environmental enrichment in rodents. Enrichment Record 3, 4-6.

Environmental enrichment is a key component of rodent animal welfare since it influences the animal’s overall well-being, provides opportunities for activity, and encourages rodent appropriate behaviors. Many aspects of rodent enrichment have received a significant...

Gaskill, B. N., Rohr, S., Lucas, J. R. et al. 2011. Working with what you've got: Changes in thermal preference and behavior in mice with or without nest material. Journal of Thermal Biology. 36(3), 193-199.

In laboratories mice are typically housed at ambient temperatures (Ta) of 20–24 °C, which are below their average preferred Ta of ≈30 °C. Adjusting laboratory Ta is not a solution because preferences differ depending on...

Breegi, S. 2011. Evaluation of nesting material for use in nude mouse colonies. American Association for Laboratory Animal Sci

Nesting material has been reported to be beneficial to mice by providing environmental enrichment as well as a means of thermoregulation. Cotton nesting material has been reported to cause conjunctivitis in athymic nude mice. We...

Gaskill, B., Garner, J. P., Pritchett-Corning, K. 2011. Energy reallocation to breeding performance through improved behavioral thermoregulation. American Association for Laboratory Animal Science [AALAS] Meeting Official Progra

Mice are housed at temperatures which increase their basal metabolic rates and impose high energy demands to maintain core temperatures. Thus, energy may be reallocated from other biologic processes to increase heat production. We hypothesized...

Gaskill, B., Winnicker, C. L., Garner, J. P. et al. 2011. The naked truth: Breeding performance in outbred and inbred strains of nude mice with and without nesting material. American Association for

In laboratories, mice are housed at ambient temperatures between 20 to 24 °C, which is below their lower critical temperature of 30 °C, but comfortable for human workers. Thus, mice are thermally stressed, which can...
