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.

Early-life adversity impacts on anxiety-related behaviors in adulthood. The effects of such adversity not only affect the animal itself, but can be passed on transgenerationally. Pervasive effects of experimentally-induced early-life stress (ELS) have been documented...

Hirata, S. 2022. Sky after 30 years: A brief biography of three biomedical research chimpanzees in Japan. Primates 63(2), 105–108.

Fehrenbach, L. A., Adekanye, A. A., Palillo, M. B. et al. 2022. Internal temperatures of packaging for overnight cross-country shipping of zebrafish (Danio rerio). Comparative Medicine 72(3), 195-203.

As the use of zebrafish (Danio rerio) as a research model continues to rise, so too will the shipping and sharing of zebrafish strains across collaborating institutions. If done incorrectly, shipping can result in significant...

Goldsmith, R., Wilson, C. 2022. Does environmental colour matter to Zebrafish. Animal Technology and Welfare 21(3), 234–237.

The aim of this study was to determine if environmental colour affects the Zebrafrish (Danio rerio) performance metrics of survival, growth rates, fecundity, and fertility. This study created tanks of different colours (green, blue, and...

Ramos, J., Balasch, J. C., Tort, L. 2021. About welfare and stress in the early stages of fish. Frontiers in Veterinary Science 8, 634434.

In conclusion, the investigations carried out up to now demonstrate that during the early stages fish show high sensitivity to many types of stressors involving an array of responses to overcome alterations that could affect...

Spiezio C., Vaglio, S., Vandelle C. et al. 2021. Effects of rearing on the behaviour of zoo-housed chimpanzees (Pan troglodytes). Folia Primatologica 92(2), 91–102.

Early-life experiences may considerably affect the behavioural patterns of adult primates. Particularly, atypical rearing practices might lead to abnormal behaviours and social-sexual deficiencies in captive, adult non-human primates. We conducted behavioural observations of mother-reared (n...

Yamanashi, Y., Teramoto, M., Morimura, N. et al. 2016. Effects of relocation and individual and environmental factors on the long-term stress levels in captive chimpanzees (Pan troglodytes): Monitoring hair cortisol and behaviors. PLOS ONE 11(7), e0160029.

Understanding the factors associated with the long-term stress levels of captive animals is important from the view of animal welfare. In this study, we investigated the effects of relocation in addition to individual and environmental...

Kranendonk, G., Schippers, E. P. 2014. A pilot study on the effects of a change in behavioural management on the behaviour of captive chimpanzees (Pan troglodytes). Applied Animal Behaviour Science 160, 127-137.

The debate on the use of chimpanzees (Pan troglodytes) in biomedical research has been ongoing for several years now. In 2012, the decision was made to retire a large number of laboratory chimpanzees in the...

van Leeuwen, E. J. C., Mulenga, I. C., Chidester, D. L. 2014. Early social deprivation negatively affects social skill acquisition in chimpanzees (Pan troglodytes). Animal Cognition 17(2), 407–414.

In a highly social species like chimpanzees, the process by which individuals become attuned to their social environment may be of vital importance to their chances of survival. Typically, this socialization process, defined by all...

Kurtzman, M. S., Craig, M. P., Grizzle, B. K. et al. 2010. Sexually segregated housing results in improved early larval survival in zebrafish. Lab Animal 39, 183-189.

Large-scale aquaculture facilities require highly optimized husbandry protocols that maximize fecundity and embryo health while minimizing cost and effort. Although zebrafish are being increasingly used for preclinical drug screens, functional genomic research and toxicological and...

Brent, L. 2009. Long-term care of chimpanzees: the role of sanctuaries. American Journal of Primatology 71(S1), 106. (32nd Meeting of the American Society of Primatologists Scientific Program, Abstract #231)

Chimpanzees (Pan troglodytes) have served in biomedical and behavioral research since the early 1900s and captive breeding programs to supply chimpanzees have been common since the 1960’s. The captive research population reached a peak of...

Branson, E. J. (Ed.) 2008. Fish Welfare. Blackwell Publishing Ltd: Oxford, UK, 300 p.
