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.

Martín, J., Barja, I., Rodríguez-Ruiz, G. et al. 2023. Hidden but potentially stressed: A non-invasive technique to quantify fecal glucocorticoid levels in a fossorial amphisbaenian reptile. Animals 13(1), 109.

To understand wildlife responses to the changing environment, it is useful to examine their physiological responses and particularly their endocrine status. Here, we validated an enzyme immunoassay (EIA) to non-invasively quantify fecal corticosterone metabolites (FCM)...

Andrade, M. P., Santos, C. M. D., De Paiva, M. M. M. et al. 2023. Assessing negative welfare measures for wild invertebrates: The case for octopuses. Animals 13(19), 3021.

Welfare metrics have been established for octopuses in the laboratory, but not for octopuses living in the wild. Wild octopuses are constantly exposed to potentially harmful situations, and the ability to assess the welfare status...

Nyqvist, D., Schiavon, A., Candiotto, A. et al. 2023. PIT-tagging Italian spined loach (Cobitis bilineata): Methodology, survival and behavioural effects. Journal of Fish Biology 102(3), 575–580.

The Italian spined loach (Cobitis bilineata) is an elongated, small-sized (

Knaebe, B., Weiss, C. C., Zimmermann, J. et al. 2022. The promise of behavioral tracking systems for advancing primate animal welfare. Animals 12(13), 1648.

Recent years have witnessed major advances in the ability of computerized systems to track the positions of animals as they move through large and unconstrained environments. These systems have so far been a great boon...

Hepps Keeney, C., Harrison, T. M. 2022. Euthanasia complications in non-domestic species. Journal of Zoological and Botanical Gardens 3(4), 616–623.

There are very few studies describing euthanasia complications in non-domestic species. The goal of this study was to survey veterinarians to determine what complications may commonly occur during the euthanasia of non-domestic species. An online...

Serres, A., Xu, C., Hao, Y. et al. 2021. The click production of captive Yangtze finless porpoises (Neophocaena asiaeorientalis asiaorientalis) is influenced by social and environmental factors. Animals 11(2), 511.

Yangtze finless porpoises use high-frequency clicks to navigate, forage, and communicate. The way in which click production may vary depending on social or environmental context has never been investigated. A group of five captive Yangtze...

Travain, T., Valsecchi, P. 2021. Infrared thermography in the study of animals’ emotional responses: A critical review. Animals 11(9), 2510.

Whether animals have emotions was historically a long-lasting question but, today, nobody disputes that they do. However, how to assess them and how to guarantee animals their welfare have become important research topics in the...

Segura-Göthlin, S., Fernández, A., Arbelo, M. et al. 2021. The validation of a non-invasive skin sampling device for detecting cetacean Poxvirus. Animals 11(10), 2814.

Poxvirus-like lesions are widely used as a potential health indicator in cetaceans, although for this application, corroboration of Poxvirus skin disease is imperative. Aiming to address skin biopsies intrusiveness, a preliminary investigation of a non-invasive...

King, K., Joblon, M., McNally, K. et al. 2021. Assessing North Atlantic right whale (Eubalaena glacialis) welfare. Journal of Zoological and Botanical Gardens 2(4), 728–739.

Welfare assessments have been largely successful in improving management and quality of life for animals in human care. This has prompted an increased interest in their use for free-ranging wild animals to assess health, environment...

Harvey, A., Beausoleil, N., Ramp, D. et al. 2020. A ten-stage protocol for assessing the welfare of individual non-captive wild animals: Free-roaming horses (Equus ferus caballus) as an example. Animals 10(1), 148.

Knowledge of the welfare status of wild animals is vital for informing debates about the ways in which we interact with wild animals and their habitats. Currently, there is no published information about how to...

Ordóñez-Grande, B., Guerreiro, P. M., Sanahuja, I. et al. 2020. Evaluation of an acute osmotic stress in European sea bass via skin mucus biomarkers. Animals 10(9), 1546.

European sea bass is a marine teleost which can inhabit a broad range of environmental salinities. So far, no research has studied the physiological response of this fish to salinity challenges using modifications in skin...
