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. 
Rushen, J., de Passillé, A. M., Appleby, M. C. et al. 2014. Alone or together: A risk assessment approach to group housing. In: Dilemmas in Animal Welfare. Appleby, M. C., Weary, D. M., Sandøe, P. (eds), 169-187. CAB International, Oxfordshire, UK.

The question of whether it is better to house animals in groups rather than alone deals with the unresolved issues at the heart of animal welfare. In particular, we need to be able to rank...

Reinhardt, V. (ed.) 2013. Compassion Makes a Difference - Discussions by the Laboratory Animal Refinement & Enrichment Forum [LAREF], Volume III. Animal Welfare Institute, Washington, DC.

This is the third volume of discussions that took place on the Laboratory Animal Refinement & Enrichment Forum (LAREF). This forum is dedicated to the exchange of personal experiences of refining the conditions under which...

Savage, S. 2013. Kidding around in the laboratory animal facility - Goat enrichment. Enrichment Record 14, 14-15.

Goat enrichment can be incredibly rewarding, not only for the goat, but for personnel as well. In our facility, we often refer to goatenrichment tasks as technician (or vet!) enrichment. Somewhere in the evolutionary development...

Gonzaleza, M., Averosa, X., de Herediaa, I. B. et al. 2013. The effect of social buffering on fear responses in sheep (Ovis aries). Applied Animal Behaviour Science 149(1-4), 13-20.

Fear in farm animals has been extensively studied because of its close relation to animal welfare. Numerous studies have categorized the behavioral responses of animals to stimuli that can elicit a fear reaction under social...

Patt, A., Gygax, L., Wechsler, B. et al. 2013. Factors influencing the welfare of goats in small established groups during the separation and reintegration of individuals. Applied Animal Behaviour Science 144(1-2), 63-72.

As a goat's separation from or reintegration into its group is likely to have an adverse effect on the welfare of both the separated goat and the remaining goats in the group, management procedures need...

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...

de Paula Vieira, A., Weary, D. M., de Passillé, A. M. 2012. Effects of the early social environment on behavioral responses of dairy calves to novel events. Journal of Dairy Science 95(9), 5149-5155.

Providing young animals the opportunity to engage in more complex social interactions is hypothesized to improve their capacity to cope with changing environments. To test the effects of the early social environment on the behavioral...

Duve, L. R., Jensen, M. B. 2012. Social behavior of young dairy calves housed with limited or full social contact with a peer. Journal of Dairy Science 95(10), 5936-5945.

This study compared the effect of individual and pair housing and age at pair housing on the social behavior of young dairy calves. Twenty-seven pairs of calves were reared from birth until 6 wk either...

Ekesbo, I. 2011. Sheep. In: Farm Animal Behavior: Characteristics for Assessment of Health and Welfare, 1st edition. Fraser, A. F. , Broom, D. M. (ed). CABI, Oxfordshire, UK. pp. 82-92.

Each chapter follows a consistent pattern describing the behavioral characteristics of the species featured. Reference is made to the natural state before domestication, leading us through the various changes to the present, demonstrating along the...

Villeneuve, L., Méthot, H., Cinq-Mars, D. et al. 2009. Effect of individual or paired housing during post-weaning on feed intake, growth rate and behaviour of lambs. Small Ruminant Research 85(2-3), 99-104.

The aim of this study was to compare the behaviour and weight gain of weaned lambs penned either in pairs or alone, with visual and tactile contacts between pens. A 2 × 2 factorial experiment...

Nowak, R., Porter, R. H., Blache, D. et al. 2008. Behavior and welfare of the sheep. In: The Welfare of Sheep. Dwyer, C. M. (ed). Springer, New York, NY.

The most important features of the behaviour of sheep are their marked sociality and the bond formation between mother and young. Sheep show a strong need to stay with their group (or subgroup for some...

Price, E. O., Thos, J. 1980. Behavioral responses of short-term isolation in sheep and goats. Applied Animal Ethology (Applied Animal Behaviour Science) 6(4), 331-339.

Behavioral stress responses to social deprivation are described.
