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. 

This is the third volume of discussions that took place on the Laboratory Animal Refinement & Enrichment Forum (LAREF). This forum is dedicated to the exchange of personal experiences of refining the conditions under which...

Clinical Laboratory Animal Medicine: An Introduction, Fourth Edition offers a user-friendly guide to the unique anatomy and physiology, care, common diseases, and treatment of small mammals and nonhuman primates. Carefully designed for ease of use...

The main objective of the program of research, of which this study is part, is to evaluate the housing and environmental enrichment for laboratory rabbits. The aim is to determine whether modifications to basic housing...

Environmental enrichment can be defined as altering the living environment of captive animals in order to provide them with opportunities to express more of their natural behavioral repertoire. The challenge of providing effective enrichment in...

The aim of this study was to evaluate different experimental gnawing blocks as cage enrichment in rabbits. One hundred and five pregnant rabbit does housed in conventional wire cages were distributed according to their parity...

The concentration of glucocorticoid metabolites (GCM) in rabbit faeces has been suggested as a non-invasive indicator of stress. In the present study, GCM concentrations were measured in faeces of fattening rabbits kept in groups of...

The primary goal of environmental enrichment should be the avoidance of abnormal behaviors in laboratory animals such as rodents, lagomorphs, dogs, cats, and nonhuman primates. A total of 13 male single-housed New Zealand White rabbits...

This report describes what rabbits need in terms of social housing, enclosure size and type, and environmental enrichment. It also describes potential husbandry-related welfare problems and how to resolve them.

The Guide for the Care and Use of Animals and the USDA Animal Welfare Regulations (AWR) outline minimum space requirements for laboratory animals, including rabbits. These documents encourage housing of animals in enclosures that allow...

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...

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...

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...

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 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...

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...

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...

Both pigs and rabbits are having a great time banging the bone on the cage - they can swing it around, and they get to chew on it too!
