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. 

Disposal of dogs retired from commercial breeding facilities presents a scientific and ethical problem. This pilot study aimed to develop criteria for identifying commercial breeding (CB) dogs likely to be at risk for problems during...

Neurophysiologic studies of NHP commonly involve their transfer from a housing enclosure to a laboratory by using a mobile chair. This transfer should be performed in a manner that is safe and minimizes stress for...

This article describes the rehoming of 10 laboratory female rabbits now living as a group in a private shelter.

In fiscal year 2016, agricultural animals such as swine, sheep, goats, and cattle represented 10% of the 820 812 animals used in USDA-regulated research. In addition to traditional agricultural animals, research studies using captive wildlife...

The aim of this study was to assess hair cortisol concentrations in New Zealand white rabbits (Oryctolagus cuniculus) that were subjected to relocation and surgery to evaluate HPA-axis activity; in addition, we used this marker...

When laboratory dogs are rehomed into private households, they experience an extreme change in their life situation. They leave their familiar, limited environment in the research facility and encounter a multitude of animate and inanimate...

To investigate how long relocation modified hair cortisol concentrations in New Zealand white rabbits, 19 rabbits were subjected to a change in their breeding facility at the beginning of the trial and then were kept...

To examine these issues [transportation of laboratory animals], the Roundtable on Science and Welfare in Laboratory Animal Use held a workshop on September 3-4, 2014, in Washington, DC. More than 200 people participated in the...

One aspect of maintaining and updating an environmental enrichment program is regular review of enrichment devices and their current uses. The review includes maintaining an accurate inventory to reflect the animal census, evaluating species-specific use...

Adoption of research dogs to private homes is increasingly common; however, the transition can be stressful. Our teaching dog program prepares former laboratory dogs for adoption by introducing challenges experienced in a home setting. All...

The overall benefits of an enrichment and exercise program for research canines has been well documented and is a required element, by the United States Department of Agriculture (USDA), of any institution’s Animal Care and...

There is increased regulatory emphasis on positive reinforcement training for husbandry, research procedures, and restraint devices. We practice acclimation, association, and positive reinforcement training with our beagle colony with goals to reduce stress for dogs...

The authors describe various methods of handling and restraining rabbits, and propose that while many methods are appropriate, rabbits respond better if only one method is used consistently.

This book focuses primarily on human kindness and compassion rather than on human cruelty, callousness, indifference, and egocentric endeavors. It is common knowledge that many lay people and professional researchers treat animals in their charge...

Routine laboratory procedures can be stressful for laboratory animals. We wanted to determine whether human handling of adult rabbits could induce a degree of habituation, reducing stress and facilitating research-related manipulation. To this end, adult...

The RSPCA/UFAW Rodent Welfare Group holds a one-day meeting every autumn so that its members can discuss current welfare research, exchange views on rodent welfare issues and share experiences of the implementation of the 3Rs...

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)...

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...

The ability to provide permanent group-housed caging for nonhuman primates involved in toxicology research is quickly becoming an important step in improving the overall quality of life for these animals. This type of caging offers...

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...

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...

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...

Stress associated with transportation has widespread effects on physiological systems in laboratory animals, including changes in the cardiovascular, endocrine, immune, central nervous, and reproductive systems. Although short-lived, these changes can confound research if animals are...

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...

Capturing rodents, nonhuman primates and birds who have escaped from their primary enclosure does not need to be a chaotic event and does not necessitate the use of stress-inducing, possibly injurious methods in most cases...
