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. 
Archibald, W., Glynn, C. 2021. Refining cages for social housing of non-human primates on ADME studies. Animal Technology and Welfare 20(2), 172-174.

The assessment and understanding of Absorption, Distribution, Metabolism and Elimination (ADME) for new pharmaceuticals is required in regulatory submissions. Typically, ADME studies are conducted using metabolism cages designed for the single housing of animals to...

Guerrero-Martin, S. M., Rubin, L. H., McGee, K. M. et al. 2021. Psychosocial stress alters the immune response and results in higher viral load during acute simian immunodeficiency virus infection in a pigtailed macaque model of human immunodeficiency virus. The Journal of Infectious Diseases 224(12), 2113–2121.

Although social distancing is a key public health response during viral pandemics, psychosocial stressors, such as social isolation, have been implicated in adverse health outcomes in general [1] and in the context of infectious disease...

Bertho, J.-M., Ancelet, S., Denais-Laliève, D. et al. 2020. Humane endpoints in severe irradiation experiments using non-human primates: A retrospective analysis. Scandinavian Journal of Laboratory Animal Science 46(1).

A retrospective statistical study has been performed in order to identify the biological, clinical and behavioural variables that could potentially predict the survival status of irradiated non-human primates (NHP) and to refine the future use...

Keeping, J. A., Reeve‐Arnold, K. E., Burns, N. M. et al. 2020. Computer‐aided photo‐identification of a rare stingray, Megatrygon microps. Journal of Fish Biology 96(3), 815-819.

A protocol for photo‐identification of individual Megatrygon microps has been defined. One hundred and four identification photographs were taken between 2005 and 2019. Spot patterns on the dorsal surface were used to identify individuals. Unique...

Lewis, R., Dawson, S., Rayment, W. 2020. Estimating population parameters of broadnose sevengill sharks (Notorynchus cepedianus) using photo identification capture-recapture. Fish Biology 97(4), 987–995.

Capture-recapture methods are now widely used for quantifying abundance and movements of elasmobranchs. This method requires that individuals in the population are uniquely identifiable and has been employed in studies that use baited underwater video...

Engel, R. M., Thomas III, M. L., Banks, R. E. 2019. Regional anesthesia for dentistry and orofacial surgery in rhesus macaques (Macaca mulatta). JAALAS 58(2), 223-230.

Regional anesthesia is a commonly used adjunct to orofacial dental and surgical procedures in companion animals and humans. However, appropriate techniques for anesthetizing branches of the mandibular and maxillary nerves have not been described for...

Heyworth, C. 2019. Inventive enrichment to facilitate weight gain in the common marmoset (Callithrix jacchus) during invasive studies. Laboratory Animal Science Professional 7(4) (December), 38-41.

To provide the highest standard of care to marmosets during invasive surgical studies, studies that often lead to weight loss, it is paramount to call upon inherent species-specific enrichment tactics to mitigate weight loss. Weight...

Maijer, A. M., Semple, S. 2016. Investigating potential effects of the contraceptive Implanon on the behavior of free-ranging adult female Barbary macaques. Journal of Applied Animal Welfare Science 19(1), 16-23.

In recent years, the use of hormonal contraception in captive, free-ranging, and wild mammal populations has increased, but the effects on these nonhuman animals’ behavior and the associated welfare impacts remain poorly understood. This study...

O'Connell, C. P., Leurs, G. 2016. A minimally invasive technique to assess several life-history characteristics of the endangered great hammerhead shark Sphyrna mokarran. Journal of Fish Biology 88(3), 1257-1264.

A dorsal-fin photo-identification technique paired with a non-invasive parallel laser photogrammetry technique was used to non-invasively identify individual Sphyrna mokarran over time. Based on the data collected over a duration of 59 days, 16 different...

Gazes, R. P., Brown, E. K., Basile, B. M. et al. 2013. Automated cognitive testing of monkeys in social groups yields results comparable to individual laboratory-based testing. Animal Cognition 16(3), 445-458.

Cognitive abilities likely evolved in response to specific environmental and social challenges and are therefore expected to be specialized for the life history of each species. Specialized cognitive abilities may be most readily engaged under...

Wolfensohn, S., Hawkins, P., Lilley, E. et al. 2013. Reducing suffering in experimental autoimmune encephalomyelitis (EAE). Journal of Pharmacological and Toxicological Methods 67(3), 169-176.

This report is based on discussions and submissions from an expert working group consisting of veterinarians, animal care staff and scientists with expert knowledge relevant to the field. It aims to facilitate the implementation of...
