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. 

This review focuses on associations of cortisol and the hormone ghrelin on abnormal oral behaviors, predominantly stereotypic behavior, in horses. Abnormal oral behaviors are prevalent in the stabled horse population. Feeding practice and satiety seem...

This study analyzed the rectal and surface temperature of the horse's body, its heart rate variability parameters, and the step length when walking and trotting geriatric horses using blankets with various thermoinsulating properties. Twenty-four hot-blooded...

Examining the literature suggests equine personality is of interest to behavior and welfare scientists and those involved in the equine industry. Study and assessment of personality is critical because of the profound implications certain traits...

Nociceptive threshold (NT) testing is widely used for the study of pain and its alleviation. The end point is a normal behavioural response, which may be affected by restraint or unfamiliar surroundings, leading to erroneous...

The measurement of pain in animals is surprisingly complex, and remains a critical issue in veterinary care and biomedical research. Based on the known utility of pain measurement via facial expression in verbal and especially...

Body language is important for communication between individuals. Body language is based on the fact that the thought of performing a known action, alone, will activate the motor neurons used for the action, resulting in...

Group housing provides horses with social contact, a lack of which is associated with health and behavior problems. Despite the benefits of group housing for horses, horse owners are concerned about aggression and resulting injuries...

Timing of reward is very important when training horses. Incorrect timing can lead to confusion and deleterious behaviors and learning will be impaired. Clicker training can be used as an important tool in training. However...

New Zealand’s code of welfare for horses and donkeys was developed by the National Animal Welfare Advisory Committee (NAWAC), under provisions in the Animal Welfare Act 1999, and issued by the Minister for Primary Industries...

Body language is important for communication between individuals. Body language is based on the fact that the thought, alone of performing a known action will activate the motor neurons used for the action, resulting in...

Meloxicam is the most frequently used NSAID in birds; however, its elimination t1/2 is highly variable among species. Because zebra finches that require analgesia could benefit from receiving meloxicam, we performed a pharmacokinetic study involving...

This second edition is fully revised, expanded, and comprehensively updated with the most current knowledge about the full array of mental health issues seen in animals. Written by key opinion leaders, internationally-recognized experts and specialists...

In nature, animals need to actively engage with the environment in order to prosper in survival and reproduction. Hence, agency is a central adaptive characteristic of animal life. In this paper, I propose that from...

Stereotypic behaviors are commonly observed in domestic equids as they are in a range of captive nondomesticated species. Estimates suggest that 19.5%-32.5% of horses perform a stereotypy. The presence of these behaviors is thought to...

As a herd species, the horse strongly desires social contact and interaction with conspecifics. Anxiety associated with social isolation may confound the display and interpretation of behavior associated with pain. This study examined the effect...

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...

There is no consensus regarding the functions of play. As play behavior is a characteristic of young stages of development, it has been suggested that the higher prevalence of adult play observed in domestic animals...

Biotelemetry can contribute towards reducing animal numbers and suffering in disciplines including physiology, pharmacology and behavioural research. However, the technique can also cause harm to animals, making biotelemetry a ‘refinement that needs refining’. Current welfare...
