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 Biology and Medicine of Rabbits and Rodents provides concise, up - to - date, reasonably comprehensive information to anyone concerned with the health, care, and management of rabbits and rodents. The book is intended...

We suggest that by providing animals with food in a more natural form (i.e., not cut to a standardized size), they would have an opportunity to process the food in a manner that best approaches...

Bonobos are known for their pacifistic behavior and their large repertoire of behaviors that are thought to serve conflict resolution. One is an unusual form of ventro-ventral mounting that facilitates genital contacts (GC). Various hypotheses...

Of the potential flags of impaired well-being in laboratory primates, alopecia has received particular regulatory focus, making it a top priority for behavioral managers. Consensus on a reliable alopecia scoring system used by multiple facilities...

Adding a few minutes of positive human interaction per animal per week to the management of captive gorillas resulted in improved well-being in several areas: the drop in abnormal behaviours, behaviours directed at the public...

Chimpanzees (Pan troglodytes) have served in biomedical and behavioral research since the early 1900s and captive breeding programs to supply chimpanzees have been common since the 1960’s. The captive research population reached a peak of...

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...

Daily activity rhythms are nearly universal among animals and their specific pattern is an adaptation of each species to its ecological niche. Owing to the extremely consistent nocturnal patterns of activity shown by golden hamsters...

It is well established that grooming underpins sociality in group-living primates, and a number of studies have documented the stress-reducing effects of being groomed. In this study, we quantified grooming behaviour and physiological stress (assessed...

Enrichment has been known to increase the well being and species typical behavior of captive animals. While much research has been done on the effectiveness of enrichment or captive monkeys and apes, research on enrichment...

Although our results do not negate the use of cortisol as a welfare indicator in Lemur catta, they do highlight the myriad of behavioural and environmental factors in addition to stress that modify cortisol excretion...

Two enrichment techniques were devised with the aim of reducing stress and improving welfare for captive lion-tailed macaques in an Indian zoo. In Study A, a log, cotton ropes and a feeding basket were added...

Consolation is a triadic postconflict interaction between a conflict participant and an uninvolved third party. We tested whether consolation alleviates postconflict stress in captive chimpanzees, Pan troglodytes. In addition, we examined whether consolation is a...

Social grooming may have both social and hygienic functions. For this analysis, we assume the ‘pick’ grooming method is more effective at cleaning than stroke and social grooming on parts inaccessible to the groomee is...

An ethological understanding of a behavioral phenomenon incorporates four levels of explanation: development, mechanism, function, and evolution. The phenomenon of socially-mediated learning has garnered a great deal of attention from ethologists, prominently including primatologists. Gregarious...

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...

Preparation of domestically bred animals for research usually involves some combination of social separation, relocation, resocialization, alterations in physical space, photoperiod, and diet, as well as exposure to novel environments. The research literature that has...

The chimpanzee is the only representative of the Great Apes that is extensively involved in biomedical research in primate laboratories. These apes are used as animal models in a variety of studies, including research on...

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...

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...

Their tendency toward natural behavior is probably little changed from their wild counterparts, despite the overwhelming influence of captivity on behavior... From a chimpanzee's point of view, it would be better to stimulate behavior characteristics...

A survey of selected enrichment programs for group-housed marmosets. Older individuals ... appear to habituate themselves less to the presence of visitors, and get very agitated when approached. ... High perches should be provided to...

A captive group of white-faced capuchins, Cebus capucinus, was presented with four deep litters in simultaneous choice (or preference) tests. A floor covering of ground corn cob, woodchips, wood wool or peat was presented once...

It is important that all females of a new [heterosexual] group are related to each other, that is, that they come from the same natal group. The introduction of unfamiliar females to a small group...
