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. 
Baran, S. W., Froberg-Fejko, K., Lecker, J. et al. 2010. Post-surgical environmental enrichment in rodents. Enrichment Record 3, 4-6.

Environmental enrichment is a key component of rodent animal welfare since it influences the animal’s overall well-being, provides opportunities for activity, and encourages rodent appropriate behaviors. Many aspects of rodent enrichment have received a significant...

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...

Cloutier, S., Wahl, K., Newberry, R. C. 2010. Playful handling mitigates the stressfulness of injections in laboratory rats. American Association for Laboratory Animal Science [AALAS] Meeting Official Program, 721 (Abstract #P126).

Rats can be playfully handled (tickled) in a manner that mimics playful social contact with conspecifics. We hypothesized that the timing of tickling in relation to an intraperitoneal injection would affect the efficacy of tickling...

Atcha, Z., Rourke, C., Neo, A. H. P. et al. 2010. Alternative method of oral dosing for rats. JAALAS 49(3), 335-343.

Oral administration of drugs to laboratory rodents typically is achieved by using the gavage technique. Although highly effective, this method occasionally can cause esophageal injury as well as restraint-associated distress, particularly with repeated use. The...

Ball, R. S. 2006. Issues to consider for preparing ferrets as research subjects in the laboratory. ILAR Journal 47(4), 348-357.

Successful housing requires knowledge of ferret behaviors including social behavior, eating habits, a general inquisitive nature, and a species-typical need to burrow and hide. Regular handling is necessary to maintain well-being. A ferret health care...

Van Loo, P., Skoumbourdis, E., Reinhardt, V. 2006. Postsurgical pairing: A discussion by the Refinement & Enrichment Forum. Animal Technology and Welfare 5(1), 17-19.

Our experience-based discussion suggests that social animals benefit from compatible companionship during post-operative recovery. The traditional practice of keeping animals alone in an unfamiliar environment after surgery increases the subjects surgery-associated stress. Providing a familiar...

Schapiro, S. J. 2005. Chimpanzees used in research: Voluntary blood samples differ from anesthetized samples. AWI Quarterly 54(3) (Summer), 15-16.

Chimpanzees were successfully trained to cooperate during injection and blood collection.

Luzzi, M., Skoumbourdis, E., Baumans, V. et al. 2005. Collecting blood from rodents: A discussion by the Laboratory Animal Refinement and Enrichment Forum. Animal Technology and Welfare 4, 99-102.

The question was asked: "In your own experience, what is the least disturbing technique - from the subject's point of view! - of blood collection for rodents?" In summary, it is fair to conclude the...

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...

Schapiro, S. J. 2000. A few new developments in primate housing and husbandry. Scandinavian Journal of Laboratory Animal Science 27(2), 103-110.

A major focus of this paper is an examination of the complementary role that behavioral management strategies play in the establishment and enhancement of well-defined nonhuman primate research resources. .... Additionally, I will discuss the...

Reinhardt, V., Reinhardt, A. 2000. Blood collection procedure of laboratory primates: A neglected variable in biomedical research. Journal of Applied Animal Welfare Science 3(4), 321-333.

A survey of 75 biomedical articles dealing with stress-dependent blood parameters in caged primates revealed that the conditions under which blood collection occurred were in most cases [72%] described either not at all or so...

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.
