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. 

We assessed dairy cows’ body postures while they were performing different stationary activities in a loose housing system and then used the variation within and between individuals to identify potential connections between specific postures and...

To assess the effects of a topical anaesthetic (TA) and buccal meloxicam (BM) on behaviour, maximum wound temperature and wound morphology following amputation dehorning of beef calves, 50 unweaned Hereford calves were randomly allocated to...

Humane euthanasia of cattle under field conditions presents special challenges for veterinarians and producers. The purpose of this study was to evaluate the effectiveness of the CASH Dispatch Kit captive-bolt system combined with improved shot...

Housing cows on hard flooring is associated with increased claw disorders. Pasture access shows a positive effect on claw health, particularly for diseases that are related to moist environments (eg, digital dermatitis). Regular documentation of...

The aim of this study was to examine effects of pasturing in dairy cows on claw condition (claw length, hardness) and on the prevalence of claw diseases. At claw trimming, a total of 240 Holstein-Friesian...

Research into the effects of intense grazing regimes on cattle behaviour and productivity will support the ethical intensification of pastoral dairy production. Two treatments were applied to two herds of 30 mid-lactation cows over 28...

Acceptable methods for the euthanasia of cattle include overdose of an anesthetic, gunshot and captive bolt. The use of anesthetics for euthanasia is costly and complicates carcass disposal. These issues can be avoided by use...

The use of pain relief during castration and dehorning of calves on commercial beef operations can be limited by constraints associated with the delivery of analgesic agents. As topical anaesthetic (TA) and buccal meloxicam (MEL)...

Grazing provides livestock better opportunities to act out their species-specific behavior compared to restrictive stable conditions. The aim of the present study was to examine the effects of daily grazing time on welfare of dairy...

Facial thermography has enabled researchers to noninvasively and continuously measure the changes of a range of emotional states in humans. The present work used this novel technology to study the effect of positive and negative...

In North American zoos, hamadryas baboons (Papio hamadryas) have traditionally been housed as single one‐male units (single male groups). In recent years, efforts have been made to house hamadryas in groups composed of multiple one‐male...

"When you keep adult Rhesus macaque (Macaca mulatta) males, adult Cynomolgus (Macaca fascicularis) males or adult Vervet males (Chlorocebus pygerythrus), in the same enclosure, is it advisable to have the canines of the males blunted...

In natural environments, cattle use trees and other abrasive surfaces to scratch and groom themselves. Modern indoor dairy cattle housing systems often lack appropriate grooming substrates, restricting the animals’ ability to groom. We assessed the...

Abnormal behavior occurs in a number of captive nonhuman primate species and is often used as an indicator of welfare. However, reported levels of abnormal behavior often vary across species, making general welfare judgments difficult...

Persistence of willingness to work has been used to measure the importance of resources and performance of species-specific behaviors. Our objectives were to develop and validate a “push-door” model to assess cattle motivation to lie...

The understanding of the ways in which cows with different personalities perceive human contact is essential for improving the quality of the human-animal relationship and therefore the welfare of dairy cows. The general objective of...

The aim of this study was to investigate if visible eye white and eye temperature measurements are feasible non-invasive physiological indicators of acute stress in cows when they are exposed to cattle crush treatment for...

Mastitis and associated pain have been identified as a major health and welfare problem affecting dairy cows, however little is known about how cows emotionally experience this illness. Qualitative behaviour assessment (QBA) is a ‘whole...

There is increasing interest in keeping dairy cows with their calves during the milk feeding period, and in reducing distress associated with separation. The aim of this study was to investigate how nutritional dependence upon...

Attentional biases towards threatening stimuli are increased when animals are in anxious states. An ability to assess negatively valanced affective states such as anxiety are important as they may be related to poor welfare. Flight...

Bovine respiratory disease (BRD) is often diagnosed in feedlots after observing behavioral changes such as anorexia, with fever confirmatory. However, this method has poor diagnostic accuracy compared to postmortem lung lesions. Little is known about...

The aim of this study was to evaluate the acute and longer-term behavioural and physiological responses caused by administering clove oil under the horn bud of calves and compare these with the responses caused by...

Hock lesions (HL) in dairy cows are a common animal welfare problem in modern dairy production with freestall housing systems, but there are no large-scale studies addressing its epidemiology in Sweden. The aims of this...

The human-animal relationship is a key component of human and farm-animal welfare. Farm surveys, particularly for pig, dairy cattle and veal calf production, which include regular human contact, showed that animals may face aversive handling...

The present observational study assessed the effect of deep straw bedding compared to cubicles during the dry period on lying-, feeding- and agonistic behaviour in Holstein cows. A total of 74 primi- (heifers) and multiparous...
