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. 
Blois-Heulin, C., Rochais, C., Camus, S. et al. 2015. Animal welfare: Could adult play be a false friend? Animal Behavior and Cognition 2(2), 156–185.

There is no consensus regarding the functions of play. As play behavior is a characteristic of young stages of development, it has been suggested that the higher prevalence of adult play observed in domestic animals...

Charmoy, K., Sullivan, T., Miller, L. 2015. Impact of different forms of environmental enrichment on foraging and activity levels in gorillas (Gorilla gorilla gorilla). Animal Behavior and Cognition 2(3), 233–240.

The maintenance of species-specific behaviors for animals in zoological institutions is of top priority, as this can help ensure high levels of animal welfare. Strict feeding schedules within institutions can often impact natural foraging behaviors...

York, C. A., Schulte, B. A. 2014. The relationship of dominance, reproductive state and stress in female horses (Equus caballus). Behavioral Processes 107, 15-21.

Maintaining a dominant position in a hierarchy requires energetically expensive aggressive displays and physical exertion. Lab based winner–loser studies, often conducted with individuals from non-social species, have shown that subordinates have higher stress hormone levels...

Siniscalchi, M., Padalino, B., Lusito, R. et al. 2014. Is the left forelimb preference indicative of a stressful situation in horses? Behavioral Processes 107, 61-67.

Evidence for behavioural and brain lateralisation is now widespread among the animal kingdom; lateralisation of limb use (pawedness) occurs in several mammals including both feral and domestic horses. We investigated limb preferences in 14 Quarter...

Bergman, T. J., Sheehan, M. J. 2013. Social knowledge and signal in primates. American Journal of Primatology 75(7), 683-694.

Primates are notable for having a rich and detailed understanding of their social environment and there has been great interest in the evolution and function of social knowledge in primates. Indeed, primates have been shown...

Rault, J.-L. 2012. Friends with benefits: Social support and its relevance for farm animal welfare. Applied Animal Behaviour Science 136(1), 1-14.

Despite growing interest in promoting positive welfare, rather than just alleviating poor welfare, potential measures of good welfare, and means to provide it, have remained elusive. In humans social support improves stress-coping abilities, health, and...

Merriman, D. K., Lahvis, G., Jooss, M. et al. 2012. Current practices in a captive breeding colony of 13-lined ground squirrels (Ictidomys tridecemlineatus). Lab Animal 41(11), 315-325.

The authors provide an update to their 2006 report on the successful large-scale captive breeding of the 13-lined ground squirrel (TLGS; Ictidomys tridecemlineatus) in their colony, now a single-source supplier of purpose-bred TLGSs for several...

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...

Carrasco, L., Colell, M., Calvo, M. et al. 2009. Benefits of training/playing therapy in a group of captive lowland gorillas (Gorilla gorilla gorilla). Animal Welfare 18(1), 9-19.

Adding a few minutes of positive human interaction per animal per week to the management of captive gorillas resulted in improved well-being in several areas: the drop in abnormal behaviours, behaviours directed at the public...

Hawkins, P., Hubrecht, R., Buckwell, A. et al. 2008. Refining Rabbit Care: A Resource for Those Working With Rabbits in Research. UFAW/RSPCA: Southwater, UK, 27 pp.

The report sets out how to provide: optimal enclosure characteristicsand size; social housing; solid flooring and substrate; raised areas; refuges; gnawing objects and dietary enrichment; positive interaction with humans; toys and objects to manipulate; for...

Crast, J. 2007. Socially-mediated learning in groups of primates: models and methods. American Journal of Primatology 69(S1), 74. (30th Meeting of the American Society of Primatologists Scientific Program, Abstract #90)

An ethological understanding of a behavioral phenomenon incorporates four levels of explanation: development, mechanism, function, and evolution. The phenomenon of socially-mediated learning has garnered a great deal of attention from ethologists, prominently including primatologists. Gregarious...

Huntingford, F. A., Adams, C., Braithwaite, V. A. et al. 2006. Current issues in fish welfare. Journal of Fish Biology 68(2), 332-372.

In common with all vertebrates, fish respond to environmental challenges with a series of adaptive neuro‐endocrine adjustments that are collectively termed the stress response. These in turn induce reversible metabolic and behavioural changes that make...
