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. 

For humans and for non-human primates heart rate is a reliable indicator of an individual’s current physiological state, with applications ranging from health checks to experimental studies of cognitive and emotional state. In humans, changes...

Completely updated and revised, and with a new author team, this second edition of Farm Animal Behaviour continues to provide essential information on normal and stereotypic behaviors in a wide variety of farm animals to...

The EU Directive 2010/63/EU changed the requirements regarding the use of laboratory animals and raised important issues related to assessing the severity of all procedures undertaken on laboratory animals. However, quantifiable parameters to assess severity...

Laboratory animals are still necessary in scientific investigation and vaccine testing, but while novel methodological approaches are not available for their replacement, the search for new, humane, easy, and painless methods is necessary to diminish...

Research has recently demonstrated that larval zebrafish show similar molecular responses to nociception to those of adults. Our study explored whether unprotected larval zebrafish exhibited altered behaviour after exposure to noxious chemicals and screened a...

Understanding how animals experience stress in a laboratory environment is crucial for improving their welfare. Increasing numbers of fish are being used in scientific studies and further research is required to ensure appropriate conditions are...

The ability to predict regular events can be adaptive for nonhuman animals living in an otherwise unpredictable environment. Animals may exhibit behavioral changes preceding a predictable event; such changes reflect anticipatory behavior. Anticipatory behavior is...

The RSPCA/UFAW Rodent (and now Rabbit) Welfare Group held a one-day meeting on 1 November 2016 at the University of Edinburgh and was attended by 70 delegates. Presentation topics included refinements in blood sampling rodents...

Whilst a great deal of research has been focused on identifying ways to assess the welfare of captive mammals and birds, there is comparatively little knowledge on how reptilian species are affected by captivity, and...

Qualitative behaviour assessment (QBA) was used to validate previous published interpretation whether human stroking has beneficial effects on lambs prematurely separated from their mothers. For a period of 8 weeks a familiar human (FH) subjected...

Recent research in nonhuman animals highlights the exciting possibility that performance on cognitive bias tasks might indirectly measure an individual’s subjective, affective state. Subjects first learn to perform a conditional discrimination task with two differentially...

Ear posture, or the frequency of postural changes, may reflect various emotional states of animals. In adult sheep (Ovis aries), the 'forward' ear posture has been associated with negative experiences whereas the 'plane' posture has...

Managing the welfare of laboratory animals is critical to animal health, vital in the understanding of phenotypes created by treatment or genetic alteration and ensures compliance of regulations. Part of an animal welfare assessment is...

Although the recognition of pain, distress and discomfort has already been described in 1985 by Morton and Griffiths there is still very little known about the establishment of score sheets especially, regarding postsurgical pain and...

The use of enzyme immunoassays (EIA) for the non-invasive measurement of glucocorticoids provides a valuable tool for monitoring health and welfare in sensitive species. We validated methods for measuring fecal glucocorticoid metabolites (FGM) using the...

The RSPCA/UFAW Rodent Welfare Group has held a one-day meeting every autumn for the last 21 years, so that its members can discuss current welfare research, exchange views on rodent welfare issues and share experiences...

Facial expressions are routinely used to assess pain in humans, particularly those who are non-verbal. Recently, there has been an interest in developing coding systems for facial grimacing in non-human animals, such as rodents, rabbits...

The most common methods for rabbit urine collection are newborn stroking, cystocentesis, and transfer to a metabolism cage.2 None of these options allow for a significant, quality amount of urine to be collected in vivo...

We assessed motor laterality in sheep to explore species-specific brain hemi-field dominance and how this could be affected by genetic or developmental factors. Further, we investigated whether directionality and strength of laterality could be linked...

Minimizing the number of animals in regulatory toxicity studies while achieving study objectives to support the development of future medicines contributes to good scientific and ethical practices. Recent advances in technology have enabled the development...

Between 1975 and 2014, housing conditions for laboratory-housed marmosets changed dramatically after the introduction of new guidelines designed to improve their care and wellbeing. According to these guidelines, our facility provided marmosets with outside enclosures...

This work investigated the differences in the reactivity of Sarda (primiparous n = 18, multiparous n = 17) and Dorset (multiparous n = 8) breeds of sheep and their singleton lambs to two challenging test...

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...

A group of 39 captive common squirrel monkeys (Saimiri sciureus) had their body temperature measurements compared by rectal thermometry and facial infrared thermal imaging (Flir i3, Flir Systems Inc). Squirrel monkeys were caught up and...

The detection and assessment of pain in animals is crucial to improving their welfare in a variety of contexts in which humans are ethically or legally bound to do so. Thus clear standards to judge...
