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. 

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...

It is not uncommon that malfunctioning in watering valves or leaks of water bottles result in the accumulation of water in rodent cages (especially during holidays and on weekends), a circumstance that can have serious...

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...

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...

A survey of 75 biomedical articles dealing with stress-dependent blood parameters in caged primates revealed that the conditions under which blood collection occurred were in most cases [72%] described either not at all or so...

A survey of 96 primatological articles revealed that cage location of research monkeys is usually not mentioned (98%), in spite of the fact that the environment of upper- and lower-row housed animals markedly differs in...

Group housing [female] guinea pigs can save space and money, while improving housing standards. The authors describe enclosure design, enrichments, and husbandry techniques that facilitate group housing female guinea pigs. No data are included in...

The objective of toxicology and pharmacology studies is to detect change or variation from normal and to interpret the significance of such change, with the intention of assessing risk to man. With non-human primates (NHPs)...

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.

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

Review of the implications of experimental or management-related manipulations of the social environment of captive primates for the animals' welfare. Relatively little empirical work has been done on the effects of manipulation of the social...

Training protocols are described to ensure cooperation of 10 single-housed baboons during blood pressure measurement in the homecage.

Description of an ingenious, simple method to minimize odor, provide species-appropriate nesting opportunities and to facilitate cleaning.

Mortality and tumor incidence in corcinogenesis experiments differ between mice caged in the top vs. bottom of the rack.
