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. 

Pregnant mice exhibit a definite preference for a processed sawdust bedding material as opposed to a commercial deodorized cellulose.

Self-biting in adult, caged macaques is an aggressive response directed to the animal's own body when the threatened object cannot be attacked (p. 128).

Single-housed males showed reduced activity and a greater incidence of stereotypical tail manipulation [substitute social response?] and pawing with hind legs than males housed in groups.

A significant increase in agonistic behavior occurred when the distribution of the food was restricted, but the amount of food remained normal. Highly significant increases in the frequency of agonistic behavior occurred with the introduction...

(1) A wild and a caged baboon population were compared on the basis of roughly 300 hr of observation on each population. The effect of different population compositions is discussed.

Companionship is far more important [than large cage-volume]. Isolated chimpanzees in large cages show more behavioural effects of environmental restriction than do members of pairs kept in small cages.

Individual monkeys exposed to sudden disturbances such as telephone ringing, confrontation by unfamiliar persons, or pinching of the abdominal skin showed an abrupt, marked elevation in plasma growth hormone.

It was found in rats that the magnitude of the stress response to being transferred into an experimental cage is virtually the same as that produced by electrical shock. ... Exposure to a new environment...

Wild mice run up to to 31 km/24 h in running wheels.

Solid-bottom caging is often associated with pressure neurophaties. Evidence suggests that solid-bottom caging, with bedding is preferred by the animals.

Conventional double-tier caging system with dark lower-rows is documented.

The procedures which we have used in testing the Effect of Person are as follows:1. The Person enters the room, stands in the doorway for 10 sec., then approaches the animal, and after 30 sec...
