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. 
Nuti, V., Cantile, C., Gazzano, A. et al. 2016. Pinch-induced behavioural inhibition (clipthesia) as a restraint method for cats during veterinary examinations: preliminary results on cat susceptibility and welfare. Animal Welfare 25(1), 115-123.

Cats are often subjected to minimally painful or forced procedures during routine clinical practice, which can be poorly tolerated, leading veterinary surgeons to need to offer physical restraint, usually aided by an assistant. The aim...

Prior, H., Bottomly, A., Champéroux, P. et al. 2016. Social housing of non-rodents during cardiovascular recordings in safety pharmacology and toxicology studies. Journal of Pharmacological and Toxicological Methods 81, 75-87.

Introduction: The Safety Pharmacology Society (SPS) and National Centre for the Replacement, Refinement & Reduction of Animals in Research (NC3Rs) conducted a survey and workshop in 2015 to define current industry practices relating to housing...

Sadekova, N., Boudreau, G., Jalbert, B. et al. 2016. The effects of housing conditions on baseline cardiovascular parameters and the sensitivity to detect changes in contractility in telemetry-implanted dogs. Journal of Pharmacological and Toxicological Methods 81, 60-74.

Introduction: There is a growing weight of evidence to suggest that myocardial contractility is an important parameter to assess as part of IND enabling studies in addition to standard assessments as per the ICH S7A...

Hedrick, C., Rowley, M., Lewis, S. 2014. Repurposing and recycling an institutionally retired enrichment device. American Association for Laboratory Animal Science [AALAS] Meeting Official Program, 564 (Abstract #P56).

One aspect of maintaining and updating an environmental enrichment program is regular review of enrichment devices and their current uses. The review includes maintaining an accurate inventory to reflect the animal census, evaluating species-specific use...

Hawkins, P. 2014. Refining housing, husbandry and care for animals used in studies involving biotelemetry. Animals 4(2), 361-373.

Biotelemetry can contribute towards reducing animal numbers and suffering in disciplines including physiology, pharmacology and behavioural research. However, the technique can also cause harm to animals, making biotelemetry a ‘refinement that needs refining’. Current welfare...

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...

Moreau, E. 2010. To squeeze or not to squeeze? A Discussion on LAREF, September, 2009. Laboratory Primate Newsletter 49(2), 3-4.

The discussion was started by the following questions: "Is the squeeze-back mechanism more or less stressful than the pole and collar system for removing a macaque from his cage for an IM (intramuscular) injection?" and...

Mikkelsen, L. F., Bentsen, H., Gerlach, B. 2003. The restraint platform - refinement of long term restraining of dogs for experimental procedures. Scandinavian Journal of Laboratory Animal Science 30(4), 217-219.

This short communication describes a new method for the long term restraining of dogs for experimental procedures like multiple blood sampling. The newly developed platform offers the dog a choice either to lie down, sit...

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.

Reinhardt, V. 1994. Traditional handling procedures of laboratory nonhuman primates are an intrinsic source of distress: What can be done? In Touch 1(4), 1 & 6-7.

With some professional expertise and goodwill, there should be no real need to resort to forceful restraint when doing research with nonhuman primates.
