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. 
Raje, S. S., Stewart, K. L. 2000. Group housing female guinea pigs. Lab Animal 29(8), 31-32.

Group housing [female] guinea pigs can save space and money, while improving housing standards. The authors describe enclosure design, enrichments, and husbandry techniques that facilitate group housing female guinea pigs. No data are included in...

Menke, C., Waiblinger, S., Fölsch, D. W. et al. 1999. Social behaviour and injuries of horned cows in loose housing systems. Animal Welfare 8, 243-258.

The results of the present study show that keeping horned dairy cows in loose housing systems is possible without unacceptable risks for cows and humans. However, it is absolutely necessary to optimize herd management conditions...

Fullwood, S., Hicks, T. A., Brown, J. C. et al. 1998. Floor space needs for laboratory mice: C57BL/6 males in solid-bottom cages with bedding. ILAR Journal 39(1), 29-36.

Different floor space allocations of cages that were barren except bedding were tested in groups of 3 male mice. Space reduction - from 129 to 32 square cm per mouse - had no impact on...

Kaliste-Korhonen, E., Kelloniemi, J., Harri, M. 1996. Cage material and rat behaviour. Scandinavian Journal of Laboratory Animal Science 23(Supplement 1), 125-128. (Conference Paper)
Van den Broek, F. A. R., Klompmaker, H., Bakkere, R. et al. 1995. Gerbils prefer partially darkened cages. Animal Welfare 4, 119-123.

Little is known about housing requirements of gerbils. ... The ten animals included in the [preference] test spent most of their time in the cages that were darkened by 50 and 75 per cent, thus...

Kaliste-Korhonen, E., Eskola, S., Rekilä, T. et al. 1995. Effects of gnawing material, group size and cage level in rack on Wistar rats. Scandinavian Journal of Laboratory Animal Science 22(4), 291-299.

Han:Wist rats were housed after weaning in groups of one, two, three or four in stainless steel cages with aspen chip bedding, with or without wooden gnawing blocks. The use of the blocks was assessed...

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.

Pough, F. H. 1991. Recommendations for the care of amphibians and reptiles in academic institutions. ILAR Journal 33(4), S1-S21.

Amphibians and reptiles differ in many respects from the mammals and birds most commonly used in biomedical research. These differences affect the physical and biological requirements of amphibians and reptiles in captivity. In this contribution...

Hughes, H. C., Campbell, S., Kenney, C. 1989. The effects of cage size and pair housing on exercise in beagle dogs. Laboratory Animal Science 39, 302-305.

Dogs in the single cage size spent slightly less time moving, but they moved at a greater speed than when housed in double sized cages [probably because of the extreme confinement condition leading to frustration...

Gray, G. 1988. Guinea pigs. Humane Innovations and Alternatives in Animal Experimentation 2, 48-49.

Initial attempts to provide the animals a covered area for refuge showed that the guinea pigs adopted the shelter very quickly and would dart under cover when startled. ... We soon realized that this was...

Mantel, N. 1980. Assessing laboratory evidence for neoplastic activity. Biometics 36, 381-399.

Mortality and tumor incidence in corcinogenesis experiments differ between mice caged in the top vs. bottom of the rack.

Feldhaus, R. A. 1980. A resting platform for dog pens. Laboratory Animal Science 30(4-1), 714-715.

After converting our dog holding facilities from commercial dog cages to pen type enclosures, it became apparent that suitable resting platforms were needed. Clear acrylic plastic was used to construct the resting platforms.
