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. 
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...

Bergman, T. J., Sheehan, M. J. 2013. Social knowledge and signal in primates. American Journal of Primatology 75(7), 683-694.

Primates are notable for having a rich and detailed understanding of their social environment and there has been great interest in the evolution and function of social knowledge in primates. Indeed, primates have been shown...

Chronic pain and distress are universally accepted conditions that may adversely affect an animal’s quality of life (QOL) and lead to the humane euthanasia of an animal. At most research institutions and zoological parks in...

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...

Coleman, K. 2012. Individual differences in temperament and behavioral management practices for nonhuman primates. Applied Animal Behaviour Science 137(3-4), 106-113.

This review will examine how individual differences in temperament might affect, or be affected by, behavioral management practices for captive primates. Measuring temperament may help us predict the outcome of social introductions. It can also...

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...

Williams-Fritze, M. J., Altieri, J. A., Clough, C. et al. 2010. Modification of a dog cage for use as an exercise unit for rabbits. American Association for Laboratory Animal Science [AALAS] Meeting Official Program, 703 (Abstract #P70).

The Guide for the Care and Use of Animals and the USDA Animal Welfare Regulations (AWR) outline minimum space requirements for laboratory animals, including rabbits. These documents encourage housing of animals in enclosures that allow...

Howard, B., Nevalainen, T., Perretta, G. (ed). 2010. The COST Manual of Laboratory Animal Care and Use: Refinement, Reduction, and Research (1st Ed). CRC Press, Boca Raton, FL.

COST Action B-24 established four working groups to research and discuss issues relevant to laboratory animal science. These included the housing of animals, environmental needs, refinement of procedures, genetically modified animals, and cost-benefit analysis. Based...

Hawkins, P., Hubrecht, R., Buckwell, A. et al. 2008. Refining Rabbit Care: A Resource for Those Working With Rabbits in Research. UFAW/RSPCA: Southwater, UK, 27 pp.

The report sets out how to provide: optimal enclosure characteristicsand size; social housing; solid flooring and substrate; raised areas; refuges; gnawing objects and dietary enrichment; positive interaction with humans; toys and objects to manipulate; for...

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...

Munds, R. A., Best, K., Hoppy, P. et al. 2007. Captive lemur response to two types of natural enrichment. American Journal of Physical Anthropology 132(S44), 175 (76th Annual Meeting of the American Association of Physical Anthropologists Program, Abstract).

Enrichment has been known to increase the well being and species typical behavior of captive animals. While much research has been done on the effectiveness of enrichment or captive monkeys and apes, research on enrichment...

Crast, J. 2007. Socially-mediated learning in groups of primates: models and methods. American Journal of Primatology 69(S1), 74. (30th Meeting of the American Society of Primatologists Scientific Program, Abstract #90)

An ethological understanding of a behavioral phenomenon incorporates four levels of explanation: development, mechanism, function, and evolution. The phenomenon of socially-mediated learning has garnered a great deal of attention from ethologists, prominently including primatologists. Gregarious...

In common with all vertebrates, fish respond to environmental challenges with a series of adaptive neuro‐endocrine adjustments that are collectively termed the stress response. These in turn induce reversible metabolic and behavioural changes that make...

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.
