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. 
Zollinger, A., Wyss, C., Bardou, D. et al. 2016. The ‘social box’ offers stallions the possibility to have increased social interactions. Journal of Veterinary Behavior 15, 84. (12th International Society of Equitation Science (ISES) Conference Abstract)

In order to give individually housed stallions the opportunity to have more social interactions, the Swiss national stud farm investigated a separation wall called ‘social box’. Sixteen adult Franches-Montagnes breeding stallions were housed for 3...

Löckener, S., Reese, S., Erhard, M. et al. 2016. Pasturing in herds after housing in horseboxes induces a positive cognitive bias in horses. Journal of Veterinary Behavior 11, 50-55.

Horses are kept in various housing systems, for example, with conspecifics in horse pens or singly in horseboxes, with or without pasturing. To provide appropriate living conditions for horses, it is necessary to know in...

Brandão, M. L., Braithwaite, V. A., Gonçalves-de-Freitas, E. 2015. Isolation impairs cognition in a social fish. Applied Animal Behaviour Science 171, 204-210.

In variable environments, animals can learn to alter their behavior to adjust to changes. Sometimes, however, this learning ability can be impaired. For example, challenges in the social or physical environment can trigger physiological responses...

Meagher, R. K., Daros, R. R., Costa, J.H. et al. 2015. Effects of degree and timing of social housing on reversal learning and response to novel objects in dairy calves. PLOS ONE 10(8), e0132828.

Rodents and primates deprived of early social contact exhibit deficits in learning and behavioural flexibility. They often also exhibit apparent signs of elevated anxiety, although the relationship between these effects has not been studied. To...

Bayne, K. A., Beaver, B. V., Mench, J. A. et al. 2015. Laboratory animal behavior. In: Laboratory Animal Medicine, 3rd edition. Fox, J. G., Anderson, L., Otto, G., et al. (eds). Elsevier, Inc., Amsterdam, NL. pp. 1617-1651.

The study of laboratory animal behavior has increased steadily over the last decade, with expanding emphasis on a variety of commonly used species. In the United States, this trend was initially focused on species for...

Modarressie, R., Gunther, C., Bakker, T. 2015. UV deprivation influences social UV preference in juvenile sticklebacks. Animal Behavior and Cognition 2(2), 186–199.

Social aggregations occur in many different animal taxa and mainly result from non-random assortment. Investigating factors that shape and maintain the composition of social aggregations are among others a main topic for understanding ecological speciation...

Hesse, S., Thunken, T. 2014. Growth and social behavior in a cichlid fish are affected by social rearing environment and kinship. Naturwissenschaften 101, 273-283.

Living in groups is a widespread phenomenon in many animal taxa. The reduction of predation risk is thought to be an important cause for the formation of groups. Consequently, grouping behavior is particularly pronounced during...

Gaillard, C., Meagher, R. K., von Keyserlingk, M. A. et al. 2014. Social housing improves dairy calves' performance in two cognitive tests. PLOS ONE 9(2), e90205.

Early social housing is known to benefit cognitive development in laboratory animals. Pre-weaned dairy calves are typically separated from their dam immediately after birth and housed alone, but no work to date has addressed the...

Jensen, M. B., Larsen, L. B. 2014. Effects of level of social contact on dairy calf behavior and health. Journal of Dairy Science 97(8), 5035-5044.

Housing preweaned dairy calves in pairs rather than individually has been found to positively affect behavioral responses in novel social and environmental situations, but concerns have been raised that close contact among very young animals...

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...

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...
