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. 

The terms short-term, temporary, and transitional are related but can have different contexts and meanings for animal husbandry. The definitions and use of these terms can be pivotal to animal housing and welfare. We conducted...

"Zoo animals" as a population are a diverse array of species from all around the globe. When managed in captivity, it is important that key aspects of natural ecology are factored into animal care, as...

The concept of the 3Rs (Refinement, Reduction and Replacement) has been used as a framework for improving the welfare of laboratory animals for the last half century. By establishing an animal-centric view on housing and...

Although most abnormal behaviors, including all stereotypies, indicate poor welfare, some that occur in rare situations are functional and do not indicate a negative situation. There is a wide range of abnormal behaviors that occur...

This is the Second Edition of a well-received book that reflects a fresh, integrated coverage of the concepts and scientific measurement of stress and welfare of animals including humans. This book explains the basic biological...

This second edition is fully revised, expanded, and comprehensively updated with the most current knowledge about the full array of mental health issues seen in animals. Written by key opinion leaders, internationally-recognized experts and specialists...

Wild animals are brought into captivity for many reasons—conservation, research, agriculture and the exotic pet trade. While the physical needs of animals are met in captivity, the conditions of confinement and exposure to humans can...

The field of zoo animal welfare science has developed significantly over recent years. However despite this progress in terms of scientific research, globally, zoo animals still face many welfare challenges. Recently, animal welfare frameworks such...

A basic assumption of most researchers is that behavior is generally functional, and indeed, in most instances the function is obvious. But in a number of cases, some behaviors of neurophysiologically ‘normal’ organisms appear to...

Many biomedical research studies use captive animals to model human health and disease. However, a surprising number of studies show that the biological systems of animals living in standard laboratory housing are abnormal. To make...

This is a report of a one-day meeting jointly convened by the RSPCA and the Animal and Plant Health Agency (APHA), which brought together around 70 researchers, veterinarians, animal technologists, regulators and others with an...

Performance of abnormal repetitive behavior (ARB) is noted in many captive wild species. ARB can be categorized into 2 basic forms: those whose aim appears to be to compulsively reach an inappropriate goal and those...

Outdoor access is often cited as a critical component of appropriate housing for great apes in captivity, and although studies have shown that offering primates choices can improve welfare, choice to access specific areas has...

The article, “Environmental and Genetic Activation of a Brain-Adipocyte BDNF/Leptin Axis Causes Cancer Remission and Inhibition,” was first published in Cell on July 8, and quickly echoed by online editions of major journals including The...

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...

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...

Species appropriate environmental enrichment should be provided to improve both animal welfare and the quality of research data. For research animals, species-appropriate Environmental Enrichment (E2) can be considered as a function of the 3 Rs...

Animals in the laboratory need the legally required "empty space" to meet their basic spatial requirements for postural adjustment, but they also deserve functional structured space for species-typical locomotor behavior and dynamic interaction with their...
