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. 
Lohmeier, R. Y., Gimberg-Henrici, C. G. E., Burfeind, O. et al. 2019. Suckling behaviour and health parameters of sows and piglets in free-farrowing pens. Applied Animal Behaviour Science 211, 25-32.

The aim of the present study was to investigate the effect of free-farrowing pens and farrowing crates on the health parameters and the suckling behaviour of sows and their piglets, which were housed in farrowing...

Yi, R., Wang, C., Zhang, X. et al. 2019. Maternal behavior, posture change, and production performance of lactating sows housed in an enriched environment. Journal of Applied Animal Welfare Science 22(3), 298-308.

This study aimed to evaluate whether adding straw to a loose-farrowing house promotes maternal functions and production. Forty-eight sows (Landrace× Large White) were housed in either a farrowing pen without straw (C, n = 24)...

King, R. L., Baxter, E. M., Matheson, S. M. et al. 2018. Sow free farrowing behaviour: Experiential, seasonal and individual variation. Applied Animal Behaviour Science 208, 14-21.

Although sow confinement at farrowing is inherently stressful, farrowing crates remain in widespread commercial use. Sows adapt to their environment, however adaptation may be counter-productive if the farrowing system changes. The current study observed the...

Mesarec, N., Prevolnik Povše, M., Škorjanc, D. et al. 2017. Gangs of piglets: Welfare and growth of imprinted and guided weaners. Applied Animal Behaviour Science 195, 44-49.

Weaning stress accompanied by outburst of aggression is a critical point in pig production as it compromises piglets’ welfare and leads to poor growth rate and health problems. Therefore, a weaning methods to smoothen the...

Christensen, J. W. 2016. Early-life object exposure with a habituated mother reduces fear reactions in foals. Animal Cognition 19(1), 171–179.

Fear reactions in horses are a major cause of horse–human accidents, and identification of effective pathways for reduction in fearfulness can help decreasing the frequency of accidents. For a young mammal, the mother is one...
