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. 
Pettersson, I. C., Weeks, C. A., Nicol, C. J. 2017. Provision of a resource package reduces feather pecking and improves ranging distribution on free-range layer farms. Applied Animal Behaviour Science 195, 60-66.

The effect of a resource package designed to reduce inter-bird pecking and increase range use was tested on fourteen free-range farms in the UK. The package comprised two types of objects intended to attract pecking...

Girard, T. E, Zuidhof, M. J., Bench, C. J. 2017. Feeding, foraging, and feather pecking behaviours in precision-fed and skip-a-day-fed broiler breeder pullets. Applied Animal Behaviour Science 188, 42-49.

Broiler breeder chickens are feed-restricted to control growth and maximize chick production. Feed restriction creates welfare concerns as conventional skip-a-day feeding can increase activity levels and oral stereotypies during the rearing period. A precision feeding...

Lopes, V. M., Sampaio, E., Roumbedakis, K. et al. 2017. Cephalopod biology and care, a COST FA1301 (CephsInAction) training school: Anaesthesia and scientific procedures. Invertebrate Neuroscience 17, 8.

Cephalopods are the sole invertebrates included in the list of regulated species following the Directive 2010/63/EU. According to the Directive, achieving competence through adequate training is a requisite for people having a role in the...

Marino, L. 2017. Thinking chickens: A review of cognition, emotion, and behavior in the domestic chicken. Animal Cognition 20(2), 127–147.

Domestic chickens are members of an order, Aves, which has been the focus of a revolution in our understanding of neuroanatomical, cognitive, and social complexity. At least some birds are now known to be on...

Sutherland, M. A., Watson, T. J., Johnson, C. B. et al. 2016. Evaluation of the efficacy of a non-penetrating captive bolt to euthanase neonatal goats up to 48 hours of age. Animal Welfare 25(4), 471-479.

Manual blunt force trauma is a common method of euthanasia or culling of goat kids, however it is difficult to apply consistently and may vary in effectiveness. Therefore, a controlled mechanical method is needed. The...

Martin, J. E., McKeegan, D. E. F., Sparrey, J. et al. 2016. Comparison of novel mechanical cervical dislocation and a modified captive bolt for on-farm killing of poultry on behavioural reflex responses and anatomical pathology. Animal Welfare 25(2), 227-241.

An alternative emergency method for killing poultry on-farm is required following European legislation changes (EU 1099/2009), which heavily restricts the use of manual cervical dislocation. This study investigated the kill efficacy of two mechanical methods...

Johannson, S. G., Raginski, C., Schwean-Lardner, K. et al. 2016. Providing laying hens in group-housed enriched cages with access to barley silage reduces aggressive and feather-pecking behaviour. Canadian Journal of Animal Science 96(2), 161-171.

Two trials were conducted to study the effect of feeding barley silage on the behaviour and performance of beak-trimmed laying hens. In each trial, 20 hens and 2 roosters were housed in each of eight...

Nääs, I. A., Garcia, R. G., Caldara, F. R. 2015. Infrared thermal image for assessing animal health and welfare. Journal of Animal Behaviour and Biometeorology 2(3), 66-72.

Infrared thermal imaging is a non-destructive testing technology that can be used to determine the superficial temperature of objects. This technology has an increasing use in detecting diseases and distress in animal husbandry within the...

Daigle, C. L., Rodenburg, T. B., Bolhuis, J. E. et al. 2014. Use of dynamic and rewarding environmental enrichment to alleviate feather pecking in non-cage laying hens. Applied Animal Behaviour Science 161, 75-85.

Feather pecking (FP) can cause feather loss, resulting in physical injuries, which may lead to cannibalism. FP appears to be a redirection of foraging behavior, which intensifies when hens have difficulty coping with stress and...

Lambeth, S. P., Schapiro, S. J., Bernacky, B. J. et al. 2013. Establishing 'quality of life' parameters using behavioural guidelines for humane euthanasia of captive non-human primates. Animal Welfare 22(4) 429-435.

Chronic pain and distress are universally accepted conditions that may adversely affect an animal’s quality of life (QOL) and lead to the humane euthanasia of an animal. At most research institutions and zoological parks in...

Coleman, K. 2012. Individual differences in temperament and behavioral management practices for nonhuman primates. Applied Animal Behaviour Science 137(3-4), 106-113.

This review will examine how individual differences in temperament might affect, or be affected by, behavioral management practices for captive primates. Measuring temperament may help us predict the outcome of social introductions. It can also...

Buijs, S., Maertens, L., Tuyttens, F. A. M. et al. 2011. Glucocorticoid metabolites in rabbit faeces - Influence of environmental enrichment and cage size. Physiology & Behavior 104(3), 469-473.

The concentration of glucocorticoid metabolites (GCM) in rabbit faeces has been suggested as a non-invasive indicator of stress. In the present study, GCM concentrations were measured in faeces of fattening rabbits kept in groups of...
