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. 
Whittaker, A. L., Howarth, G. S. 2014. Use of spontaneous behaviour measures to assess pain in laboratory rats and mice: How are we progressing? Applied Animal Behaviour Science 151, 1-12.

The understanding and recognition of pain in laboratory rats and mice has advanced considerably in recent times. However, there is evidence that despite these advances, analgesics are still relatively underutilised in these species. One possible...

Melotti, L., Bailoo, J., Murphy, E. et al. 2014. Play in rats: Association across contexts and types, and analysis of structure. Animal Behavior and Cognition 1(4), 489–501.

Play has been proposed as a promising indicator of positive animal welfare. We aimed to study play in rats across contexts (conspecific/heterospecific) and types (social: pinning, being pinned; solitary: scampering), and we investigated its structure...

Yuki, S., Okanoya, K. 2014. Behavioral correlates of 50-kHz ultrasonic vocalizations in rats: Progressive operant discrimination learning reduces frequency modulation and increases overall amplitude. Animal Behavior and Cognition 1(4), 452–463.

Ultrasonic vocalizations (USVs) in rats are thought to contain ecological signals reflecting emotional states. These USVs are centered on 50-kHz, and frequency modulation (FM) is hypothesized to indicate positive emotion; however, results from recent studies...

Makowska, I. J., Weary, D. M. 2013. Assessing the emotions of laboratory rats. Applied Animal Behaviour Science 148, 1-12.

Rats are one of the most commonly used species in research, and decades of testing have yielded a large amount of information pertaining to their experience of emotion. The aim of this review is to...

Pater, C. S. 2013. Rabbit hypnosis as a form of mild restraint: A forgotten method. American Association for Laboratory Animal Science [AALAS] Meeting Official Program, 615 (Abstract #PS42).

Rabbit hypnosis or “trancing” was a common restraint technique used for minor procedures such as: nail clipping, tooth trimming, eye exams, and subcutaneous injections. In years past the technique was originally used on pet rabbits...

Hrapkiewicz, K., Colby, L. A., Denison, P. 2013. Clinical Laboratory Animal Medicine: An Introduction (4th Ed). Wiley-Blackwell, Ames, IA.

Clinical Laboratory Animal Medicine: An Introduction, Fourth Edition offers a user-friendly guide to the unique anatomy and physiology, care, common diseases, and treatment of small mammals and nonhuman primates. Carefully designed for ease of use...

Hawkins, P., Burn, C., Hurst, J. et al. 2011. Report of the 2010 RSPCA/UFAW rodent welfare group meeting - The effect of husbandry on welfare and promoting good practice. Animal Technology and Welfare 10(2), 105-114.

The RSPCA/UFAW Rodent Welfare Group holds a one-day meeting every autumn so that its members can discuss current welfare research, exchange views on rodent welfare issues and share experiences of the implementation of the 3Rs...

Harkness, J. E., Turner, P. V., Vande Woude, S. et al. 2010. Biology and Medicine of Rabbits and Rodents (5th Ed.). Wiley-Blackwell, Ames, Iowa.

The Biology and Medicine of Rabbits and Rodents provides concise, up - to - date, reasonably comprehensive information to anyone concerned with the health, care, and management of rabbits and rodents. The book is intended...

Barley, J., Mikkelsen, L. F., Francis, R. et al. 2007. Enforced restraint of rodents: A discussion by the Refinement & Enrichment Forum. Animal Technology and Welfare 6(1), 11-13.

The question was asked: "Rodents are often restrained for data collection procedures, such as blood collection and injection, by coaxing them into tubes, for example syringe cylinders or perspex tubes. What can be done to...

Van der Harst, J. E., Spruijt, B. M. 2007. Tools to measure and improve animal welfare: Reward-related behaviour. Animal Welfare 16(S), 67-73.

This paper presents a descriptive overview of the evidence obtained thus far for the three proposed uses of reward-related behavior. First, it was shown that previous experiences influence anticipatory behaviour to rewards in rats. This...

Lepschy, M., Touma, C., Hruby, R. et al. 2007. Non-invasive measurement of adrenocortical activity in male and female rats. Laboratory Animals 41(3), 372-387.

Rats are widely used in biomedical research as animal models for human diseases. However, due to their small body size, blood sampling is complicated and invasive and thereby can seriously interfere with endocrine functions and...

National Research Council. 2003. Guidelines for the Care and Use of Mammals in Neuroscience and Behavioral Research. National Academic Press: Washington, DC, 223 pp.

Expanding on the National Research Council’s Guide for the Care and Use of Laboratory Animals, this book deals specifically with mammals in neuroscience and behavioral research laboratories. It offers flexible guidelines for the care of...

Sharp, J. L., Zammit, T., Azar, T. A. et al. 2003. Are "by-stander" female Sprague-Dawley rats affected by experimental procedures? Contemporary Topics in Laboratory Animal Science 42(1), 19-28.

The objective of this study was to test the hypotheses that female rats are stressed by being in the same room as animals subjected to common husbandry and experimental procedures and that the level of...

Lenox, R. H., Kant, G. J., Sessions, G. R. et al. 1980. Specific hormonal and neurochemical responses to different stressors. Neuroendocrinology 30(5), 300-308.

The neuroendocrine and neurochemical responses of rats to 5 min of cold exposure versus 5 min of forced immobilization were determined and compared. We found that plasma hormones and brain neurochemical systems responded differently to...
