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. 
Salzen, E. A., Marriott, B. M. 1991. Technical note: A primatrail or an inexpensive cage expansion for group housing small primates. Journal of Medical Primatology 20(2), 94-96.

An inexpensive method for converting standard laboratory cages into colony units for housing small primate species is described. In addition to increasing the volume of space available to the animals, this system also provides a...

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...

Fajzi, K., Reinhardt, V., Smith, M. D. 1989. A review of environmental enrichment strategies for singly-caged nonhuman primates. Lab Animal 18(2), 23-35.

Comprehensive literature review dealing with the following topics: a) Group housing versus single housing; b) Enrichment strategies using inanimate objects; c) Socialization with conspecifics; d) Role of animal care staff.

Love, J. A. 1988. Housing for rabbits. Humane Innovations and Alternatives in Animal Experimentation 2, 47-48.

In most laboratory situations, rabbits are kept isolated in cages. ... We have attempted to correct this deficiency by keeping rabbits in either large tubs which can accommodate six or more animals or in indoor/outdoor...

Chamove, A. S., Anderson, J. R., Morgan-Jones, S. C. et al. 1982. Deep woodchip litter: Hygiene, feeding, and behavioral enhancement in eight primate species. International Journal for the Study of Animal Problems 3, 308-318.

Sixty-seven animals from eight primate species were used to assess improved husbandry techniques. The presence of woodchips as a direct-contact litter decreased inactivity and fighting, and increased time spent on the ground. Placing food in...

Nerem, R. M., Levensque, M. J., Cornhill, J. F. 1980. Social environment as a factor of diet induced atherosclerosis. Science 208, 1475-1476.

Rabbits were fed a high-cholesterol diet to induce atherosclerosis. Animals who received special attention from a person (frequent handling, petting, playing, gentle vocalization) showed a markedly lower incidence of atheroslerosis than subjects who received no...
