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 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...

Maintaining the psychologic wellbeing of nonhuman primates housed in a laboratory setting is an important aspect in providing the best possible care for these animals. Nonhuman primates kept in captivity can begin to display abnormal...

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...

Fish have the same stress response and powers of nociception as mammals. Their behavioural responses to a variety of situations suggest a considerable ability for higher level neural processing – a level of consciousness equivalent...

The aim of the experiment was to study the effects of cage density (1, 3 and 5 rabbits per cage) and sex (male and female) on stress parameters of young rabbits. A total of 90...

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...

This article provides a brief historical background of the events and circumstances that led to the 1985 Animal Welfare Act (AWA) amendments. It describes the development of the regulations promulgated by the US Department of...

The perceived benefits of permanent, pre-weaning mother-infant separation are not supported by scientific findings. ... As long as there is an excessive number of monkeys and insufficient cage space, there is no ethically legitimate reason...

Twenty-six reports provide detailed information of how primates can be trained to voluntarily cooperate - rather than resist - during blood collection, injection, topical drug application, blood pressure measurement, urine collection, and capture.

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...

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...

Several structural enrichment enhancers are described. When a barrel with an opening in the front was hung from the roof of the siamang enclosure, our then solitary male, Mitch, spent much of his time looking...

Comprehensive literature review dealing with the following topics: a) Group housing versus single housing; b) Enrichment strategies using inanimate objects; c) Socialization with conspecifics; d) Role of animal care staff.

Rabbits were fed a high-cholesterol diet to induce atherosclerosis. Animals who received special attention from a person (frequent handling, petting, playing, gentle vocalization) showed a markedly lower incidence of atheroslerosis than subjects who received no...
