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.

In the last decade several surveys of primate care and training programs highlight a common theme; despite scientific evidence that animal training can be effective in reducing stress, increasing efficiency and improving veterinary care, animal...

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...

Bennett, K. J., Hill, V. A., Brock, K. et al. 2011. Enhanced canine enrichment and its effects on staff morale. American Association for Laboratory Animal Science [AALAS] Meeting Official Program, 772 (Abstract #P123).

The use of dogs in research has been under increasing public scrutiny and criticism over the past several years, and our institution has been no exception. Of particular concern is the use of Class B...

Watts, A. 2010. Thinking outside the box in box training. Tech Talk [The Newsletter for Laboratory Animal Science Technicians] 15(2), 3.

At the Oregon National Primate Research Center, we train animals to enter transfer boxes using positive reinforcement training (PRT), a type of training in which the trainer reinforces desired behaviors (such asentering the transfer box)...

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...

Pluijmakers, J. J. T. M., Appleby, D. L., Bradshaw, J. W. S. 2010. Exposure to video images between 3 and 5 weeks of age decreases neophobia in domestic dogs. Applied Animal Behaviour Science 126(1-2), 51-58.

Restricted experience in early life is known to contribute to long-lasting predispositions to fear and anxiety in mammals. It is commonplace for young domestic dogs not to experience many features of the environment in which...

Burgess, W., French, E. D., Kendall, L. V. 2010. A socialization program to improve research dog adoption rates. American Association for Laboratory Animal Science [AALAS] Meeting Official Program, 714 (Abstract #P104).

Investigators using companion animals for research are often faced with the dilemma of what to do with healthy animals when a study is complete. At our institution, it is not uncommon for investigators to submit...

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...

McMillan, J. L., Perlman, J. E., Bloomsmith, M. A. 2007. Components of an animal training program at a large institution. American Journal of Primatology 69(S1), 117. (30th Meeting of the American Society of Primatologists Scientific Program, Abstract #177)

The application of positive reinforcement training (PRT) has increased in zoological, laboratory, and research settings in recent years, however there is little literature pertaining to the development and implementation of such programs. Over the past...

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...

Bassett, L., Buchanan-Smith, H. M., McKinley, J. et al. 2003. Effects of training on stress-related behavior of the common marmost (Callithrix jacchus) in relation to coping with routine husbandry procedures. Journal of Applied Animal Welfare Science 6(3), 221-233.

Using positive reinforcement, J. McKinley trained 12 common marmosets (Callithrix jacchus) to provide urine samples on request. The study then exposed the marmosets to mildly stressful, routine husbandry procedures (i.e., capture and weighing). The nonhuman...

The use of "pre-invasive" implantable radio telemetry has revolutionized the collection of physiological data under stress-free conditions. It is now possible to measure accurately 'normal' baseline data of haemodynamic and electrical parameters in conscious and...

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., Liss, C., Stevens, C. 1995. Restraint methods of laboratory non-human primates: A critical review. Animal Welfare 4(3), 221-238 .
