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. 
Coleman, K. 2011. Caring for nonhuman primates in biomedical research facilities: Scientific, moral and emotional considerations. American Journal of Primatology 73(3), 220-225.

Animal care for nonhuman primates (NHPs) in biomedical facilities has undergone major changes in the past few decades. Today, most primate facilities have dedicated and highly trained animal care technicians who go to great efforts...

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

Kuhar, C. W., Smith, K., Soltis, J. 2008. The visitor effect on apes: real or imaginary? Enriching or stressful? American Journal of Primatology 70(S1), 23 (31st Meeting of the American Society of Primatologists Scientific Program, Abstract #8).

The “visitor effect” problem, whether zoo visitors are stressful or enriching to zoo animals, is made difficult to analyze by numerous methodological challenges. The extremes in visitor attendance patterns during the holiday season at Disney’s...

American Journal of Primatology 70(S1), 29. (31st Meeting of the American Society of Primatologists Scientific Program, Abstract #28)

Live, direct observations are often used to collect behavioral data. However, the presence of an observer may affect the behavior of unhabituated subjects. This study was conducted to determine the effect of an observer’s presence...

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.

Meder, A. 1992. Effects of the environment on the behaviour of lowland gorillas in zoos. Primate Report 32, 167-183.

The purpose of this study was to observe as many gorilla groups as possible and to compare their behaviour in different exhibits, social structures and visitor situation. Gorillas were studied in 15 zoos, they lived...
