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. 
Marriott, B. M., Marriott, R. W., Norris, J. et al. 1993. A semi-natural habitat for housing small, nonhuman primates. Journal of Medical Primatology 22, 348-354.

A semi-natural habitat that was designed to house a group of squirrel monkeys is described. Animals maintained in this environment were healthy, and none of the animals exhibited locomotor stereotypies. This facility was easier and...

Reinhardt, V., Reinhardt, A. 1992. Quantitatively tested environmental enrichment options for singly-caged nonhuman primates: A review. Humane Innovations and Alternatives in Animal Experimentation 6, 374-384.

Compatible companionship has a therapeutic effect on behavioral disorders, providing long- term stimulation of a great variety of species-typical social behavior patterns. Inanimate objects have little impact on behavioral disorders, but some of them provide...

Salzen, E. A., Marriott, B. M. 1991. Technical note: A primatrail or an inexpensive cage expansion for group housing small primates. Journal of Medical Primatology 20(2), 94-96.

An inexpensive method for converting standard laboratory cages into colony units for housing small primate species is described. In addition to increasing the volume of space available to the animals, this system also provides a...

Reinhardt, V., Pape, R. 1991. An alternative method for primate perch installation. Lab Animal 20(8), 47-48.

Modification of squeeze cages is described allowing the installation of a perch that does not interfere with the normal operation of the cage.

Novak, M. A., Suomi, S. J. 1989. Psychological well-being of primates in captivity. ILAR Journal 31(3), 5-15.

Recent amendments to the Animal Welfare Act will, upon taking effect, require that researchers who maintain nonhuman primates in captivity house their animals in such a way as to “promote their psychological well-being.” Unfortunately, no...

Fajzi, K., Reinhardt, V., Smith, M. D. 1989. A review of environmental enrichment strategies for singly-caged nonhuman primates. Lab Animal 18(2), 23-35.

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.

Chamove, A. S., Anderson, J. R., Morgan-Jones, S. C. et al. 1982. Deep woodchip litter: Hygiene, feeding, and behavioral enhancement in eight primate species. International Journal for the Study of Animal Problems 3, 308-318.

Sixty-seven animals from eight primate species were used to assess improved husbandry techniques. The presence of woodchips as a direct-contact litter decreased inactivity and fighting, and increased time spent on the ground. Placing food in...

Tardif, S. D., Bales, K., Williams, L. et al. 2006. Preparing New World monkeys for laboratory research. ILAR Journal 47(4), 307-315.

New World monkeys represent an important but often poorly understood research resource. The relatively small size and low zoonotic risk of these animals make them appealing as research subjects in a number of areas. However...
