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.

Refinement of animal care and housing is an important shared goal - and challenge - of the team of research, veterinary, and animal care personnel charged with ensuring the wellbeing of laboratory animals. This study...

Skoumbourdis, E., Coke Murphy, C. 2009. Studies and snack bites. Animal Welfare Institute (AWI) Quarterly 58(1) Winter, 12-13.

Veterinary technician Evelyn Skoumbourdis and environmental enrichment coordinator Casey Coke Murphy discuss proper feeding of small laboratory mammals.

Camacho, I. N., Schultz, C. 2009. A rational approach to enriched nutrition for nonhuman primates. American Association for Laboratory Animal Science [AALAS] Meeting Official Program, 543 (Abstract #PS38).

Obesity is a concern with nonhuman primates (NHPs) housed in captivity for extended periods of time, mostly due to overfeeding and lack of exercise. This is often compounded by environmental enrichment programs that include different...

Schütz, K. E., Cox, N. R., Matthews, L. R. 2008. How important is shade to dairy cattle? Choice between shade or lying following different levels of lying deprivation. Applied Animal Behaviour Science 114(3-4), 307-318 .

Provision of shade to dairy cattle in summer can alleviate negative effects of heat stress. The aim of this study was to investigate the relative importance of shade to lactating dairy cows in different ambient...

Dwyer, C. M. , Lawrence, A. B. 2008. Introduction to Animal Welfare and the Sheep. In: The Welfare of Sheep. Animal Welfare, volume 6. Dwyer, C. M. (Ed.). Springer: Dordrecht, 1-40.

Concerns for the lives of animals have been voiced for centuries, with concerns about the welfare of agricultural animals increasing since the 1960s. Animal welfare concerns arise for many reasons: care about the quality of...

Branson, E. J. (Ed.) 2008. Fish Welfare. Blackwell Publishing Ltd: Oxford, UK, 300 p.

Fish have the same stress response and powers of nociception as mammals. Their behavioural responses to a variety of situations suggest a considerable ability for higher level neural processing – a level of consciousness equivalent...

Smith, A. C., Swindle, M. M. 2006. Preparation of swine for the laboratory. ILAR Journal 47(4), 358-363.

Swine are an important model in many areas of biomedical research. These animals have been used predominantly as preclinical models involving surgical and interventional protocols. The systems most commonly studied include cardiovascular, integumentary, digestive, and...

Conour, L. A., Murray, K. A., Brown, M. J. 2006. Preparation of animals for research -- Issues to consider for rodents and rabbits. ILAR Journal 47(4), 283-293.

This article provides details to consider when preparing to use animals in biomedical research. The stress of transport and receipt of animals into a new environment mandate the need for a period of stabilization and...

Huntingford, F. A., Adams, C., Braithwaite, V. A. et al. 2006. Current issues in fish welfare. Journal of Fish Biology 68(2), 332-372.

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...

Widowski, T. M., Yuan, Y., Gardner, J. M. 2005. Effect of accommodating sucking and nosing on the behaviour of artificially reared piglets. Laboratory Animals. 39(2), 240-250.

Neonatal piglets are often used in biomedical research applications that require artificial rearing. Social housing can be problematic because the piglets develop belly nosing, navel and ear sucking that can result in injury. Our objective...

Bayne, K. 2005. Potential for unintended consequences of environmental enrihment for laboratory animals and research results. ILAR Journal 46(2), 129-139.

Many aspects of the research animal's housing environment are controlled for quality and/or standardization. Of recent interest is the potential for environmental enrichment to have unexpected consequences such as unintended harm to the animal, or...

Woolley, A. P. A. H. 1997. Requirements of biomedical research in terms of housing and husbandry for non-human primates: Pharmacology & Toxicology. Primate Report 49, 37-41.

The objective of toxicology and pharmacology studies is to detect change or variation from normal and to interpret the significance of such change, with the intention of assessing risk to man. With non-human primates (NHPs)...

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.
