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. 
Golledge, H., Richardson, C. (Eds.) 2024. The UFAW Handbook on the Care and Management of Laboratory and Other Research Animals (9th ed.). Wiley-Blackwell. 1040 p.

The latest edition of the seminal reference on the care and management of laboratory and research animals. The newly revised ninth edition of The UFAW Handbook on the Care and Management of Laboratory and Other...

Claydon, M., Brereton, J., Rose, P. 2024. Never be mute about bird welfare: Swanning around with environmental enrichment. Zoo Biology 43(1), 83–91.

Environmental enrichment (EE) is commonly provided to animals managed under human care, being beneficial to behavioral diversity and improving animal welfare. Use of EE appears to be particularly beneficial to individual wild animals spending a...

Baskir, E., Parsons, A., Elden, M. et al. 2023. Quantifying acute behavioral reactions of Bali mynas (Leucopsar rothschildi) to environmental and progressively challenging enrichment. Journal of Zoological and Botanical Gardens 4(1), 176–190.

Animals use specific behaviors and skills to overcome challenges and access resources. Environmental enrichment is provided to animals in human care to both promote species-appropriate behaviors and reduce undesired behaviors. Feather pecking in birds is...

Alaniz, A. J., Astudillo-Hinojosa, K., Soto, A. F. et al. 2022. Rapid behavioral recovery based on environmental enrichment of a white-throated toucan (Ramphastos tucanus: Ramphastidae) affected by collision trauma. Journal of Veterinary Behavior 57, 1-5.

Captive animals that have experienced traumatic events require a high range of care prior to reintroducing them into their natural habitat; and this care should ensure their welfare in captivity. This report shows the ethological...

Brereton, J. E., Myhill, M. N. G., Shora, J. A. 2021. Investigating the effect of enrichment on the behavior of zoo-housed southern ground hornbills. Journal of Zoological and Botanical Gardens 2(4), 600–609.

Enrichment is essential for the welfare of many zoo-housed animals, yet the value of enrichment is not well understood for all taxa. As an intelligent, long-lived species, the southern ground hornbill (Bucorvus leadbeateri) is a...

Glaspell, S. 2020. Flight to freedom: Behavior modification of an undomesticated pigeon using human interaction. Laboratory Animal Science Professional 8(2) (March/April), 58-61.

The white-crowned pigeon, Patagioenas leucocephala, is a species of bird not often used in research. This may be related to its anxiety during normal human interactions, such as with cage changing. Our institution acquired a...

Schmitt, V. 2019. Implementing portable touchscreen-setups to enhance cognitive research and enrich zoo-housed animals. Journal of Zoo and Aquarium Research 7(2), 50-58.

To understand the evolutionary development of cognition, comparing the cognitive capacities of different animal species is essential. However, getting access to various species with sufficient sample sizes can be very challenging. Zoos, housing large ranges...

Volkmann, J. L., Evans, C. A., Buckmaster, C. 2018. Pigeons: Flying to new heights. Laboratory Animal Science Professional 6(1) (March), 33-34.

When singly or pair housed in cages, pigeons have a relatively small area in which to walk and stretch or flap their wings. More space is required to allow pigeons to be housed in numbers...

Nelson Slater, M., Hauber, M. E. 2017. Olfactory enrichment and scent cue associative learning in captive birds of prey. Zoo Biology 36(2), 120–126.

As the use of enrichment in zoos has become a standardized husbandry practice, the continued improvement of enrichment programs should be concomitant with empirical validation of those practices. The role of scent as enrichment remains...

Perret, A., Henry, L., Coulon, M. et al. 2015. Social visual contact, a primary “drive” for social animals? Animal Cognition 18(3), 657–666.

Social animals are always searching for conspecifics, thereby expressing a genuine “social need”. This need is illustrated by the fact that social isolation can induce isolation syndromes that can be attenuated by devices such as...

Brown, C. 2010. Organic wheatgrass as environmental enrichment. Lab Animal 39(3), 74-75.

Environmental enrichment must be provided for the various animal species that are housed in laboratory animal facilities. Wheatgrass can be used as a natural form of enrichment that requires minimal preparation and effort. Wheatgrass is...

Conte, A. 2005. Pigeons used in research: From barren single-housing to an enriched environment. AWI Quarterly 54(3) (Summer), 14-15.

Single-caged pigeons were successfully transferred to compatible group-housing.
