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.

There is every reason to believe that individuals who care about their wards on a personal level actually treat the animals better (Herzog, 2002, p. 30). Compassion for animals used in research, testing and teaching...

Wolfle, T. L. 2002. Introduction. ILAR Journal 43(1), 1-3.

Introduction to ILAR's issue Implications of Human-Research Interactions and Bond in the Laboratory. I was encouraged not to assign names to the many rhesus monkeys in my charge. I was admonished that the animals are...

Iliff, S. A. 2002. An additional R - Remembering the animals. ILAR Journal 43(1), 38-47.

Davis, H. 2002. Prediction and preparation: Pavlovian implications of research animals discriminating among humans. ILAR Journal 43(1), 19-26.

Russow, L.-M. 2002. Ethical implications of the human-animal bond. ILAR Journal 43(1), 33-37.

Researchers must continue to question the barriers that have traditionally been erected against forming HABs [human-animal bonds] in the name of objectivity and to investigate seriously the ways in which fostering the formation of HABs...

Herzog, H. 2002. Ethical aspects of relationships between humans and research animals. ILAR Journal 43(1), 27-32.

More often than not, moral dilemmas are the result of good people trying to do the right thing when the right thing is unclear [p. 29]. I have spoken with some animal care staff who...

Chang, F. T., Hart, L. A. 2002. Human-animal bonds in the laboratory: How animal behavior affects the perspectives of caregivers. ILAR Journal 43(1), 10-18.

People are attracted by the animals to become caregivers in laboratories, which points to the importance of providing caregivers opportunities for rewarding interactions with the animals. Opportunities that enhance the comfort of the animals and...

Bayne, K. 2002. Development of the human-research animal bond and its impact on animal well-being. ILAR Journal 43(1), 4-9.

The various roots of human-animal bonding in the research laboratory setting are reviewed. The development of these relationships is enriching to both personnel and animals inasmuch as people who care about their animals are committed...

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.

Pecenko, N. 1997. Visitors as an environmental enrichment. In: Proceedings on the International Conference on Environmental Enrichment. Holst, B. (ed), 325-33. Copenhagen Zoo, Frederiksberg, DK.

Because of the influence in behaviour, we can say that visitors are a kind of environmental enrichment. .... Sometimes visitors have a negative effect (increase of aggressive behaviour, begging for food) and in some cases...

Fouts, R. S., Fouts, D. H., Jensvold, M. L. A. et al. 1994. An enriching approach to captive chimpanzee care. In Touch 1(1), 1 & 4-8.

The social environment [which includes the care providers] is perhaps the most critical factor in chimpanzee well-being, more important even than designs of the living space.

Reinhardt, V. 1992. Environmental enhancement plan for previously single-caged adult rhesus macaques (Macaca mulatta). Animal Technology 43, 115-119.

To promote the well-being of previously single-caged adult (older than 5 years) rhesus macaques (Macaca mulatta) and the quality of research done with them, the following environmental enhancement plan has been developed and implemented at...

Reinhardt, V. 1992. Are rhesus macaques really so aggressive? International Zoo News 39(1), 14-19.

Several years of experience with pair housing of previously single-caged adult rhesus macaques and venipuncture in the home cage of cooperative, non-resisting animals lead the author to conclude that rhesus macaques are not as aggressive...

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...
