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. 

It is widely recognised that single housing is detrimental to the welfare of social species. However, some experimental procedures dictate that laboratory animals are housed individually. There is evidence to suggest that, by mimicking social...

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...

Environmental enrichment must be provided for the various animal species that are housed in laboratory animal facilities. Wheatgrass can be used as a natural form of enrichment that requires minimal preparation and effort. Wheatgrass is...

To do justice to the diverse approaches to enrichment and behavioral management around the world would entail a discussion beyond the limits of this publication. Therefore, guidelines and regulations in a representative sample of countries...

It is now more than 20 years since both Council of Europe Convention ETS123 and EU Directive 86/609/EEC were introduced, to promote the implementation of the Three Rs in animal experimentation and to provide guidance...

This column discusses the use of novel dietary supplements as environmental enrichment for rodents and rabbits. Items are commercially available from lab animal supply companies. The purpose of enrichment is to encourage behaviors that are...

The regulation of the use of animals for experimental and other scientific purposes and the determination of minimum required standards of animal care and accommodation within Europe is generally informed by recommendations and conventions at...

In Japan, the Architectural Institute of Japan (AIJ) provides guidelines for laboratory animal facilities and equipment. Guidelines are not legally binding but serve as the authority for proper facilities and equipment management. The first guideline...

The report sets out how to provide: optimal enclosure characteristicsand size; social housing; solid flooring and substrate; raised areas; refuges; gnawing objects and dietary enrichment; positive interaction with humans; toys and objects to manipulate; for...

The German law on animal protection might be more utilitarian than the American law. The legislators obviously tried to meet the needs of the animals. However, its poor definitions of main concepts such as pain...

On the basis of this paper's conclusions (White et al., 1989), the USDA decreased their cage size requirements and removed the increased space requirement for breeding guinea pigs. How well did the study determine the...

Valuable recommendations for the species-adequate housing and species-approriate care of guinea pigs; topics include Housing (enclosure size, substrate, shelter, nesting material), Environmental Enrichment, and Husbandry (light, temperature, humidity, cleaning).

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...

A resource is provided for the creation of an institutional program that balances the scientific mission of an institution with the well-being of the animals used in support of the research. The concept of harmonizing...

Since the 1998 publication of The Psychological Well-Being of Nonhuman Primates by the National Research Council, and the 1991 implementation of the 1985 Animal Welfare Act Amendment, many formal and informal nonhuman primate enrichment programs...

Only social contact satisfies the goal of promoting a wide variety of species-typical activities while at the same time reducing or preventing the development of abnormal behavior... A number of toys should be provided initially...

This article provides a brief historical background of the events and circumstances that led to the 1985 Animal Welfare Act (AWA) amendments. It describes the development of the regulations promulgated by the US Department of...

Summary of a collection of articles pertaining to the topic of environmental enrichment.

In this article, laws and guidelines relating to rodent enrichment are reviewed, the natural behaviors of select rodent species are discussed, and an overview of widely used types of enrichment in laboratory rodent management is...

Normal behavior plays a key role in facilitating homeostasis, especially by allowing the animal to control and modify its environment. Captive environments may interfere with these behavioral responses, and the resulting stress may alter many...

Environmental enrichment for laboratory animals has come to be viewed as a potential method for improving animal well-being in addition to its original sense as a paradigm for learning how experience molds the brain. It...

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...

Environmental conditions such as housing and husbandry have a major impact on the laboratory animal throughout its life and will thereby influence the outcome of animal experiments. However, housing systems for laboratory animals have often...

The question was raised how the environment of guinea pigs can be best enriched in the research laboratory setting. In summary, social-housing is the most species-appropriate living environment for guinea pigs. If a research protocol...
