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.

Reinhardt, V., Reinhardt, A. 2001. Legal space requirement stipulations for animals in the laboratory: Are they adequate? Journal of Applied Animal Welfare Science 4(2), 143-149.

Animals in the laboratory need the legally required "empty space" to meet their basic spatial requirements for postural adjustment, but they also deserve functional structured space for species-typical locomotor behavior and dynamic interaction with their...
