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. 
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...

Kulpa-Eddy, J. A., Taylor, S., Adams, K. M. 2005. USDA perspectives on environmental enrichment for animals. ILAR Journal 46(2), 83-94.

This article provides a brief historical background of the events and circumstances that led to the 1985 Animal Welfare Act (AWA) amendments. It describes the development of the regulations promulgated by the US Department of...

Smith, A. L., Mabus, S. L., Muir, C. et al. 2005. Effects of housing density and cage floor space on three strains of young adult inbred mice. Comparative Medicine 55(4), 368-376.

Some recommendations in the Guide for the Care and Use of Laboratory Animals (the Guide) are based on best professional judgment. Our current efforts are directed toward replacement with data-driven standards. We demonstrated earlier that...

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...

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.

Hirsjärvi, P. A., Väliaho, T. 1995. Gentled and nonhandled Wistar rats in a mildly novel open-field situation. Scandinavian Journal of Laboratory Animal Science 22(3), 265-269.

Open-field behaviour of individually gentled and nonhandled adult male Wistar rats was studied in a mildly novel test situation. The gentled rats were more active and showed fewer signs of fear on the first trial...

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.

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...
