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. 
Kaliste-Korhonen, E., Eskola, S., Rekilä, T. et al. 1995. Effects of gnawing material, group size and cage level in rack on Wistar rats. Scandinavian Journal of Laboratory Animal Science 22(4), 291-299.

Han:Wist rats were housed after weaning in groups of one, two, three or four in stainless steel cages with aspen chip bedding, with or without wooden gnawing blocks. The use of the blocks was assessed...

Hirsjärvi, P. A., Väliaho, T. 1995. Gentled and nonhandled Wistar rats in a mildly novel open-field situation. Scandinavian Journal of Laboratory Animal Science 22(3), 265-269.

Open-field behaviour of individually gentled and nonhandled adult male Wistar rats was studied in a mildly novel test situation. The gentled rats were more active and showed fewer signs of fear on the first trial...

Love, J. A., Hammond, K. 1991. Group-housing rabbits. Lab Animal 20(8), 37-43.

The management and success of a group-housing indoor/outdoor pen system for rabbits [mainly females] is described and discussed. Over a three-year study period a total of 141,000 rabbits were included in the assessment. The levels...

Love, J. A. 1988. Housing for rabbits. Humane Innovations and Alternatives in Animal Experimentation 2, 47-48.

In most laboratory situations, rabbits are kept isolated in cages. ... We have attempted to correct this deficiency by keeping rabbits in either large tubs which can accommodate six or more animals or in indoor/outdoor...

Panksepp, J., Herman, B. H., Vilberg, T. et al. 1980. Endogenous opioids and social behavior. Neuroscience and Biobehavioral Reviews 4(4), 473-487.

Evidence for the hypothesis that brain-opioids mediate social affect and social attachments is summarized. Opiates and opioids are very effective in reducing social separation-induced distress vocalizations (DVs), in puppies, young guinea pigs and chicks, while...

Nerem, R. M., Levensque, M. J., Cornhill, J. F. 1980. Social environment as a factor of diet induced atherosclerosis. Science 208, 1475-1476.

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...

Mackay-Sim, A., Laing, D. G. 1980. Discrimination of odours from stressed rats by non-stressed rats. Physiology and Behavior 24, 699-704.

Placing a rat into a new cage triggers release of corticosterones. This endocrine response is augmented if the new environment is one in which other rats had previously been subjected to stress.

Lenox, R. H., Kant, G. J., Sessions, G. R. et al. 1980. Specific hormonal and neurochemical responses to different stressors. Neuroendocrinology 30(5), 300-308.

The neuroendocrine and neurochemical responses of rats to 5 min of cold exposure versus 5 min of forced immobilization were determined and compared. We found that plasma hormones and brain neurochemical systems responded differently to...

Gartner, K., Buttner, D., Dohler, R. et al. 1980. Stress response of rats to handling and experimental procedures. Laboratory Animals 14, 267-274.

Serum corticosterone levels increased significantly within four minutes, reached a peak at 15 minutes and were back to control values 60 minutes after cage displacement. Prolactin, TSH, LH and FSH serum concentrations were also affected...

Vanjonack, W. J., Johnson, H. D. 1973. Relationship of thyroid and adrenal function to fur-chewing in the chinchilla. Comparative Biochemistry and Physiology 45, 115-120.

The fur-chewing chinchillas showed increased thyroid activity (P

Hall, C. S., Ballachey, E. L. 1932. A study of the rat's behavior in a field: A contribution to method in comparative psychology. University of California Publications in Psychology 6, 1-12.

THE OPEN-FIELD (OF) TEST, originally developed by Hall (Hall & Ballachey, 1932), is one of the most widely used methods in the study of emotionality in rodents. The test is conducted in an enclosed open...
