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.

Chatigny, F. 2019. The controversy on fish pain: A veterinarian’s perspective. Journal of Applied Animal Welfare Science 22(4), 400-410.

Fish welfare is still a relatively new field. As such, regulations and protocols to ensure fish welfare are currently limited and vary considerably in different jurisdictions. This is in part because of the ongoing controversy...

Attribution of emotions to horses, as well as understanding how environmental factors may influence such states, may influence owners' and caretakers' attitudes toward horse welfare. This, in turn, may influence how they manage and treat...

Waran, N., Randle, H., Preshaw, L. et al. 2019. Through their eyes: the challenge of assessing equine emotional state. Journal of Veterinary Behavior 29, 151. (13th International Society of Equitation Science (ISES) Conference Abstract)

Animal welfare assessment has traditionally relied on measures of physical health and changes in behavior and physiology related to negative emotional states such as pain and stress. However, it is now widely accepted that good...
