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. 
Cruden, J. 2013. Can regular access to floor pens affect caged rabbit behavior? American Association for Laboratory Animal Science [AALAS] Meeting Official Program, 615-616 (Abstract #PS43).

The main objective of the program of research, of which this study is part, is to evaluate the housing and environmental enrichment for laboratory rabbits. The aim is to determine whether modifications to basic housing...

Bulens, A., Beirendonck, S., Van Thielen, J. et al. 2013. The enriching effect of non-commercial items in stabled horses. Applied Animal Behaviour Science 143(1), 46-51.

The effect of the provision of simple objects to stabled horses on their behaviour was investigated to determine whether these objects can affect horses' behaviour in a positive way and thus enrich their environment. A...

Kistler, C., Hegglin, D., Würbel, H. et al. 2011. Preference for structured environment in zebrafish (Danio rerio) and checker bards (Puntius oligolepis). Applied Animal Behaviour Science 135(4), 318-327.

Information about the welfare and husbandry of pet and laboratory fish is scarce although millions of fish are sold in pet shops and used in laboratory research every year. Inadequate housing conditions can cause behavioural...

Research Department, RSPCA. 2011. Rabbits: Good Practice for Housing and Care (3rd edition).

This report describes what rabbits need in terms of social housing, enclosure size and type, and environmental enrichment. It also describes potential husbandry-related welfare problems and how to resolve them.

Spence, R., Magurran, A. E., Smith, C. 2011. Spatial cognition in zebrafish: The role of strain and rearing environment. Animal Cognition 14(4), 607–612.

Two strains of zebrafish, WIK and a second-generation wild strain were reared in either a structurally simple or complex environment and compared in their ability to locate a food reward in a five-chambered maze. There...

Williams-Fritze, M. J., Altieri, J. A., Clough, C. et al. 2010. Modification of a dog cage for use as an exercise unit for rabbits. American Association for Laboratory Animal Science [AALAS] Meeting Official Program, 703 (Abstract #P70).

The Guide for the Care and Use of Animals and the USDA Animal Welfare Regulations (AWR) outline minimum space requirements for laboratory animals, including rabbits. These documents encourage housing of animals in enclosures that allow...

Mayfield, K. L., Livingston, L. G., Kirby, D. W. 2010. Floor housing rabbits to promote weight loss and species-specific behaviors. American Association for Laboratory Animal Science [AALAS] Meeting Official Program, 706-707 (Abstract #P81).

Standard rabbit caging offers little in the way of exercise, vertical space for species-typical movements (that is, standing on hind limbs), or ample space for proper social introductions. One commonly used rabbit breed, the New...

Leming, J. T., Jensen, E., Plate, G. 2010. From dog kennels to rabbit housing: Complete cage makeover encompasses behavioral enrichment for laboratory rabbits. American Association for Laboratory Animal Science [AALAS] Meeting Official Program, 659 (Abstract #PS14).

A major objective of our behavioral management committee was to improve rabbit housing in our large academic research institution. As our dog population decreased, we were left with several rooms of empty stainless steel kennel...
