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 most common method used for temporary restraint of small primates is to tie or tape them to a cross-shaped plywood board.

A peak in dominance is reached at the night year of age wherefter growing age contributes to a decline in social rank. Parallel to the age-dependent rise and decline in social rank the animal gain...

The results clearly indicated that illumination levels is an important variable affecting the general activity of mice. The animals showed less fearfulness and emotionality under low illumination conditions.

Reproductive improvements due to paper nesting material were dramatic. The 10.8 pups per litter weaned by mothers nested in paper was very significantly higher than the 7.0 pups weaned by those with wood shaving. A...

Excellent overview of the species-typical behavior of wild rhesus macaques. Infants continue to nurse ... until they were probably about one year of age. Weaning definitely occurred when the next sibling was born.

The bonnet macaque is seen only in areas where there are at least a few large trees, and, given a supply of food and water, the presence of some large trees seems to be the...

At a very rough estimate, chimpanzees in the Budongo Forest spent an average of from 50 to 75 percent of the daylight hours in trees.

A clear description of functional analysis of nonhuman primate communicative behaviors. Looking away, or rather looking anywhere except toward the opponent, is a widespread sign of submission.

Excellent overview of the species-typical behavior of wild langurs. The presence of suitable sleeping trees also affects langur group distribution more than does the edibility of the vegetation.

Animals used in biomedical research should not be considered as mere animals but rather as standardized biological resarch tools.

Excellent overview of the species-typical behavior of wild baboons. Weaning takes place between the eleventh to fifteenth month.

Increases in activity level accompany increased illumination in single-caged subjects

Photograph documenting a group of baboons who has taken refuge from a lioness by climbing into the trees. These trees are smaller than those used for sleeping. ... The danger of predators sets limits on...

The importance of infantile stimulation for later tolerance for handling is demonstrated.

Regular human contact during the socialization period (age 3-14 weeks) is particularly important to assure that adult dogs will not be fearful of humans.
