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. 

The fine-scale grading of the severity experienced by animals used in research constitutes a key element of the 3Rs (replace, reduce, and refine) principles and a legal requirement in the European Union Directive 2010/63/EU. Particularly...

The lion (Panthera leo) is an iconic resident of zoos and wild animal parks throughout the world. Regular assessment of the morbidity of captive lions is necessary to address wellness concerns and improve the healthcare...

The contemporary approach to pain measurement in people and animals seeks to measure the affective (emotional) component of the pain experience using structured questionnaires with formal scoring methodology. Chronic pain has wide-ranging impacts which affects...

Canine behavioral disorders, such as various forms of fear and anxiety, are a major threat for the wellbeing of dogs and their owners. They are also the main cause for dog abandonment and relinquishment to...

When laboratory dogs are rehomed into private households, they experience an extreme change in their life situation. They leave their familiar, limited environment in the research facility and encounter a multitude of animate and inanimate...

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...

Bexsero® is a new vaccine in the UK which since September 2015 has been added to the childhood immunisation programme for the prevention of Meningitis B. The in-vivo test as performed in Biological Services Division...

We have developed an accurate method of detecting and monitoring internal ovarian tumours. This reduces the number of procedures, refines the way we detect internal tumours and defines an end point before animals become visibly...

Judgement bias tests of animal affect and hence welfare assume that the animal’s responses to ambiguous stimuli, which may herald positive or negative outcomes, are under instrumental control and reflect ‘optimism’ or ‘pessimism’ about what...

Play is an enigmatic behaviour, the function of which is still debated, despite more than a century of research. We discuss the evolutionary function of play behaviour, focusing on the domestic dog (Canis familiaris), a...

Cognitive processes are influenced by underlying affective states, and tests of cognitive bias have recently been developed to assess the valence of affective states in animals. These tests are based on the fact that individuals...

Welfare problems in laboratory mice can be a consequence of an ongoing experiment, or a characteristic of a particular genetic line, but in some cases, such as breeding animals, they are most likely to be...

Previous research on humans and animals suggests that the analysis of sleep patterns may reliably inform us about welfare status, but little research of this kind has been carried out for non-human animals in an...

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...

Fracture healing is a complex regeneration process which produces new bone tissue without scar formation. However, fracture healing disorders occur in approximately 10% of human patients and cause severe pain and reduced quality of life...

Postoperative monitoring of pain and distress in small rodents is not standardized, and widely accepted score sheets are not available. Here we describe a score sheet used in abdominal surgery of rodents, with particular reference...

The study of subjective well-being in nonhuman animals is growing in the field of psychology, but there are still only a few published studies and the focus is on primates. To consider whether the construct...

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...

Aggression is the leading cause of death in young laboratory mice, representing a major welfare issue. Many of the experimental measures used in traditional aggression research, especially those focusing on territorial aggression (e.g., resident/intruder) are...

An animal health program involves identification of health conditions, as well as treatment and disposition of rodents. In most facilities with a large rodent population, the initial identification of health conditions is typically accomplished by...

Prevention or alleviation of pain in laboratory mice is a fundamental requirement of in vivoresearch. The mouse grimace scale (MGS) has the potential to be an effective and rapid means of assessing pain and analgesic...

Behavioural changes that occur as animals become sick have been characterized in a number of species and include the less frequent occurrence of ‘luxury behaviours’ such as playing, grooming and socialization. ‘Sickness behaviours’ or behavioural...
