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. 
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...

Hawkins, P., Hubrecht, R., Buckwell, A. et al. 2008. Refining Rabbit Care: A Resource for Those Working With Rabbits in Research. UFAW/RSPCA: Southwater, UK, 27 pp.

The report sets out how to provide: optimal enclosure characteristicsand size; social housing; solid flooring and substrate; raised areas; refuges; gnawing objects and dietary enrichment; positive interaction with humans; toys and objects to manipulate; for...

Crast, J. 2007. Socially-mediated learning in groups of primates: models and methods. American Journal of Primatology 69(S1), 74. (30th Meeting of the American Society of Primatologists Scientific Program, Abstract #90)

An ethological understanding of a behavioral phenomenon incorporates four levels of explanation: development, mechanism, function, and evolution. The phenomenon of socially-mediated learning has garnered a great deal of attention from ethologists, prominently including primatologists. Gregarious...

Van Loo, P. L. P., Kuin, N., Sommer, R. et al. 2007. Impact of 'living apart together' on postoperative recovery of mice compared with social and individual housing. Laboratory Animals 41(4), 441-455.

We investigated whether housing two female mice in a cage, separated by a grid partition ('living apart together') counters the adverse effects of individual housing on postoperative recovery. Results indicated that socially housed mice appear...

Van Loo, P., Skoumbourdis, E., Reinhardt, V. 2006. Postsurgical pairing: A discussion by the Refinement & Enrichment Forum. Animal Technology and Welfare 5(1), 17-19.

Our experience-based discussion suggests that social animals benefit from compatible companionship during post-operative recovery. The traditional practice of keeping animals alone in an unfamiliar environment after surgery increases the subjects surgery-associated stress. Providing a familiar...

Huntingford, F. A., Adams, C., Braithwaite, V. A. et al. 2006. Current issues in fish welfare. Journal of Fish Biology 68(2), 332-372.

In common with all vertebrates, fish respond to environmental challenges with a series of adaptive neuro‐endocrine adjustments that are collectively termed the stress response. These in turn induce reversible metabolic and behavioural changes that make...

Hutchinson, E., Avery, A., Van de Woude, S. 2005. Environmental enrichment for laboratory rodents. ILAR Journal 46(2), 148-161.

In this article, laws and guidelines relating to rodent enrichment are reviewed, the natural behaviors of select rodent species are discussed, and an overview of widely used types of enrichment in laboratory rodent management is...

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...

Vermeer, J. 1997. The formation of a captive squirrel monkey group. International Zoo News 44, 146-149.

It is important that all females of a new [heterosexual] group are related to each other, that is, that they come from the same natal group. The introduction of unfamiliar females to a small group...

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.

Marriott, B. M., Marriott, R. W., Norris, J. et al. 1993. A semi-natural habitat for housing small, nonhuman primates. Journal of Medical Primatology 22, 348-354.

A semi-natural habitat that was designed to house a group of squirrel monkeys is described. Animals maintained in this environment were healthy, and none of the animals exhibited locomotor stereotypies. This facility was easier and...
