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. 

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...

In a typical cage of barbered mice, all but one individual will have near-identical patterns of hair loss. The intact individual (the 'barber') is removing hair from its companions. .. Barbers hold down their cage...

Expanding on the National Research Council’s Guide for the Care and Use of Laboratory Animals, this book deals specifically with mammals in neuroscience and behavioral research laboratories. It offers flexible guidelines for the care of...

Using positive reinforcement, J. McKinley trained 12 common marmosets (Callithrix jacchus) to provide urine samples on request. The study then exposed the marmosets to mildly stressful, routine husbandry procedures (i.e., capture and weighing). The nonhuman...

In the United States, there are an estimated 15,000 individually caged macaques. If 10% of these animals exhibit visible injuries resulting from self-biting and another 10% show unnoticed self-biting behavior, then about 3,000 animals (20%)...

Comprehensive discussion and review of the possible causes of stereotypic behaviour in laboratory macaques. A great deal of debate and controversy has surrounded what does does and does not constitute psychological well-being in primates [p...

The purpose of this study was to link abnormal behaviors often expressed by chimpanzees living in captive environments to factors related to their care and housing. Individuals who had spent more time with their mothers...

Giving captive animals the opportunity to interact with objects in a “playful” manner is often considered a method of environmental enrichment. However, the occurrence of play in nonavian reptiles is controversial and poorly documented. Similarly...

Simple bamboo pipe feeder is described and tested in group-housed animals. The aim of the study was to [successfully] increase foraging time with an increasing number of feeding devices [brawn bowl, bamboo pipe]. ... Prior...

The present article represents a consensus view of the appropriate utilization of chimpanzees in AIDS research arrived at as a result of a meeting of a group of scientists involved in AIDS research with chimpanzees...

The high prevalence of stereotypies in mice kept in standard animal facilities is underscored.

Authors describe the "Wellness Program" of the Primate Foundation of Arizona (PFA) devoted to producing physically and behaviorally normal chimpanzees. Psychological well-being is a major focus. In this paper, the authors present protocols specific to...

Animals living in upper-row cages were more active and engaged in more close contact amicable behavior than animals living in lower-row cages. Those located in the half of the room nearer the window were more...

We examined the effects of a synthetic fleece pad on cage stereotypies in individually housed cynomolgus monkeys. Animals exhibited idiosyncratic repertoires of stereotyped behaviour, including repetitive pacing, swaying circling, bouncing, cage charging, and rocking that...

I wrote this book because I believe that the welfare of animals is a very important subject but one about which there is a lot of confusion and muddled thinking. I wanted to great deal...

New World monkeys represent an important but often poorly understood research resource. The relatively small size and low zoonotic risk of these animals make them appealing as research subjects in a number of areas. However...
