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. 
Buchanan-Smith, H. M., Badihi, I. 2012. The psychology of control: Effects of control over supplementary light on welfare of marmosets. Applied Animal Behaviour Science 137(3), 166–174.

It is often argued that increasing the amount of control that animals have over various aspects of their environment has a positive effect on their welfare, despite limited empirical evidence. We gave 12 pairs of...

Pomerantz, O., Terkel, J., Suomi, S. J. et al. 2012. Stereotypic head twirls, but not pacing, are related to a ‘pessimistic’-like judgment bias among captive tufted capuchins (Cebus apella). Animal Cognition 15(4), 689–698.

Abnormal stereotypic behaviour is widespread among captive non-human primates and is generally associated with jeopardized well-being. However, attributing the same significance to all of these repetitive, unvarying and apparently functionless behaviours may be misleading, as...

Research Department, RSPCA. 2011. Rabbits: Good Practice for Housing and Care (3rd edition).

This report describes what rabbits need in terms of social housing, enclosure size and type, and environmental enrichment. It also describes potential husbandry-related welfare problems and how to resolve them.

Zhang, L. 2011. Voluntary oral administration of drugs in mice. Protocol Exchange [version 1, protocol preprint].

Oral administration of substances is a common procedure in scientific experiments using laboratory animals and typically is achieved in conscious animals by using the intragastric gavage technique. While highly effective, this method can be technically...

Špinka, M., Wemelsfelder, F. 2011. Environmental challenge and animal agency. Animal Welfare 27–43.

Challenges are there to be overcome – seen usually as problems to avoid rather than as opportunities to enjoy. However, for humans a life without challenge would be likely to be dull and boring, lacking...

Spence, R., Magurran, A. E., Smith, C. 2011. Spatial cognition in zebrafish: The role of strain and rearing environment. Animal Cognition 14(4), 607–612.

Two strains of zebrafish, WIK and a second-generation wild strain were reared in either a structurally simple or complex environment and compared in their ability to locate a food reward in a five-chambered maze. There...

Ellegaard, L., Cunningham, A., Edwards, S. et al. 2010. Welfare of the minipig with special reference to use in regulatory toxicology studies. Journal of Pharmacological and Toxicological Methods 62(3), 167-183.

This paper reviews the animal welfare challenges associated with the use of minipigs in toxicology testing, and compares these to published knowledge on the other widely used non-rodent species (dogs and non-human primates). Welfare challenges...

Atcha, Z., Rourke, C., Neo, A. H. P. et al. 2010. Alternative method of oral dosing for rats. JAALAS 49(3), 335-343.

Oral administration of drugs to laboratory rodents typically is achieved by using the gavage technique. Although highly effective, this method occasionally can cause esophageal injury as well as restraint-associated distress, particularly with repeated use. The...

Krohn, T. C., Hansen, A. K. 2010. Mice prefer draught-free housing. Laboratory Animals 44(4), 370-372.

An increasing number of rodents are housed in individually ventilated cage (IVC) systems, as these seem to be very effective for the protection of animals against infections, as well as protecting the staff against allergens...

Brilot, B. O., Asher, L., Bateson, M. 2010. Stereotyping starlings are more ‘pessimistic.’ Animal Cognition 13(5), 721–731.

Negative affect in humans and animals is known to cause individuals to interpret ambiguous stimuli pessimistically, a phenomenon termed ‘cognitive bias’. Here, we used captive European starlings (Sturnus vulgaris) to test the hypothesis that a...

Kasanen, I. H. E., Inhilä, K. J., Nevalainen, J. I. et al. 2009. A novel dietary restriction method for group-housed rats: Weight gain and clinical chemistry characterization. Laboratory Animals 43, 138-148.

Laboratory rodents are usually fed ad libitum. Moderate dietary restriction decreases mortality and morbidity compared with ad libitum feeding. There are, however, problems in achieving dietary restriction. Traditional methods of restricted feeding may interfere with...

Down, N., Skoumbourdis, E., Walsh, M. et al. 2005. Pole-and-collar training of macaques: A discussion by the Laboratory Animal Refinement and Enrichment Forum. Animal Technology and Welfare 4(4), 157-161.

The question was asked: "I am currently pole-and-collar training one of our adult pair-housed rhesus females and hope to get her to graduate to the chair in the next few weeks. Winnie remains sitting when...

Duncan, I. J., Petherick, J. C. 1991. The implications of cognitive processes for animal welfare. Journal of Animal Science 69(12), 5017–5022.

In general, codes that have been designed to safeguard the welfare of animals emphasize the importance of providing an environment that will ensure good health and a normal physiological and physical state, that is, they...
