Refinement Database

Database on Refinement of Housing, Husbandry, Care, and Use of Animals in Research

This database, created in 2000, is updated every four months with newly published scientific articles, books, and other publications related to improving or safeguarding the welfare of animals used in research.

Tips for using the database:

  • This landing page displays all of the publications in the database.
  • Use the drop-down menus to filter these publications by Animal Type, Setting, and/or Topic.
  • Clicking on a parent category (e.g., Rodent) will include publications relating to all the items in that category (e.g., Chinchilla, Gerbil, Guinea Pig, etc.).
  • You may also add a keyword to further narrow your search.
  • Please note that at this time, only publications dated 2010 or later (with some exceptions) can be filtered by Animal Type and Topic, and only publications dated 2020 or later (with some exceptions) can be filtered by Setting. Most publications older than 2010 can only be searched by keyword. 
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...

Pawlowicz, A., Demner, A., Lewis, M. H. 2010. Effects of access to voluntary wheel running on the development of stereotypy. Behavioural Processes 83(3), 242-246.

Stereotyped motor behaviors are a common consequence of environmental restriction in a wide variety of species. Although environmental enrichment has been shown to substantially reduce stereotypy levels, the various components of enrichment have not been...

Harper, V., Frey, A., Bradley, D. et al. 2010. Recognizing and addressing stereotypic behaviors. Tech Talk [The Newsletter for Laboratory Animal Science Technicians] 15(4), 2.

The combination of mouse igloos and running wheels proved to be highly effective in reducing flipping, circling, and jumping.

Latham, N., Mason, G. 2010. Frustration and perseveration in stereotypic captive animals: Is a taste of enrichment worse than none at all? Behavioural Brain Research 211(1), 96-104.

Stereotypic behaviours are common in animals in impoverished housing, arising from two complementary processes: (1) thwarted attempts to perform motivated behaviours; (2) forebrain dysfunction impeding normal behavioural inhibition. When enriched animals are moved to impoverished...

Branson, E. J. (Ed.) 2008. Fish Welfare. Blackwell Publishing Ltd: Oxford, UK, 300 p.

Fish have the same stress response and powers of nociception as mammals. Their behavioural responses to a variety of situations suggest a considerable ability for higher level neural processing – a level of consciousness equivalent...

Conour, L. A., Murray, K. A., Brown, M. J. 2006. Preparation of animals for research -- Issues to consider for rodents and rabbits. ILAR Journal 47(4), 283-293.

This article provides details to consider when preparing to use animals in biomedical research. The stress of transport and receipt of animals into a new environment mandate the need for a period of stabilization and...

Garner, J. P., Weisker, S. M., Dufour, B. et al. 2004. Barbering (fur and whisker trimming) by laboratory mice as a model of human trichotillomania and obsessive-compulsive spectrum disorders. Comparative Medicine 54(2), 216-224.

In a typical cage of barbered mice, all but one individual will have near-identical patterns of hair loss. The intact individual (the 'barber') is removing hair from its companions. .. Barbers hold down their cage...

Reinhardt, V. 1997. Training nonhuman primates to cooperate during handling procedures: A review. Animal Technology 48, 55-73.

Twenty-six reports provide detailed information of how primates can be trained to voluntarily cooperate - rather than resist - during blood collection, injection, topical drug application, blood pressure measurement, urine collection, and capture.

Burghardt, G. M., Ward, B., Rosscoe, R. 1996. Problem of reptile play: Environmental enrichment and play behavior in a captive Nile soft‐shelled turtle, Trionyx triunguis. Zoo Biology 15(3), 223-238.

Giving captive animals the opportunity to interact with objects in a “playful” manner is often considered a method of environmental enrichment. However, the occurrence of play in nonavian reptiles is controversial and poorly documented. Similarly...

Wurbel, H., Stauffacher, M. 1994. Standard-Haltung fur Labormause - Probleme und Losungsasatze. Tierlaboratorium 17, 109-118.

The high prevalence of stereotypies in mice kept in standard animal facilities is underscored.
