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. 

Some otherwise non-aggressive dogs may display fear-induced aggression under stressful conditions. Admittance to an animal shelter is a stressful experience for dogs, and aggression is often used as a criterion by shelters for precluding opportunities...

The assessment of personality in farm animals and its relation to other behavioural and physiological traits is of growing scientific and practical interest. Therefore, the aims of the present study were first to assess the...

Pets have numerous, effective methods to communicate with their human hosts. Perhaps most conspicuous of these are distress vocalizations: in cats, the ‘miaow’ and in dogs, the ‘whine’ or ‘whimper’. We compared a sample of...

The Association of Primate Veterinarians (APV) recognizes that several forms of restraint, including physical and chemical, are necessary for the safe handling of nonhuman primates (NHPs). The following guidelines aim to provide information to researchers...

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...

The root cause of most welfare issues for horses is human behavior – people doing, or not doing, certain care, management or training practices. In addition, there is a gap between advancing scientific knowledge about...

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...

Oxytocin is increasingly recognized to have a role in human-dog bonding and interactions and a positive influence on various health outcomes including cardiovascular function and stress reactivity. This review summarizes current research investigating human-dog interactions...

In comparison to non-human animals, humans are highly flexible in cooperative tasks, which may be a result of their ability to understand a partner’s role in such interactions. Here, we tested if wolves and dogs...

This study examined the relationships between the attitudes and the management behaviour of the farmer and the on-farm welfare of their ewes. To our knowledge, this is the first study investigating these relationships in extensive...

Cattle mother-offspring contact calls encode individual-identity information; however, it is unknown whether cattle are able to maintain individuality when vocalising to familiar conspecifics over other positively and negatively valenced farming contexts. Accordingly, we recorded 333...

This study reveals, for the first time, an interspecific synchronization in long-term stress levels. Previously, acute stress has been shown to be highly contagious both among humans and between individuals of other species. Here, long-term...

In fiscal year 2016, agricultural animals such as swine, sheep, goats, and cattle represented 10% of the 820 812 animals used in USDA-regulated research. In addition to traditional agricultural animals, research studies using captive wildlife...

Equine assisted interventions (EAIs) include all therapeutic interventions aimed at improving human wellbeing through the involvement of horses. Due to the prominent emotional involvement traditionally characterizing their relation with humans, horses developed sophisticated communicative skills...

Personality, defined as consistent between-individual variation in clusters of behavioral traits independent of factors such as age or sex, emerges in most animal species tested so far. The number of invertebrate species discovered to have...

An understanding of the factors influencing the human-animal relationship is relevant in the development of welfare interventions for working equids. However, the link between the psychological attributes of animal owners, such as empathy level and...

The aim of this study was to conduct a series of paper-based exercises in order to assess the negative (adverse) welfare impacts, if any, of common interventions on domestic horses across a broad range of...

Over-activity, or excessive locomotion and barking in the kennel, may be unattractive to adopters and an indicator of poor welfare of kenneled dogs. The study assessed the efficacy of two common enrichment strategies, providing calm...

It is well established that human interaction has positive effects on shelter dogs. This work set out to answer the question: “Does one 15-min petting session make a difference for shelter dogs?” Fifty-five dogs were...

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...

Human-animal bond is receiving increasing attention and is thought to confer benefits on well-being and performance in working animals. One important benefit of bonding is the “safe base” an attachment figure provides, which manifests in...

Welfare concerns not only the absence of negative emotional experiences but also the presence of positive experiences. However, scientific investigation on positive emotions in farm animals has been long neglected. This study aimed to investigate...

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...

Individual variation in behaviour has been shown to have important ecological and evolutionary consequences. Research on animal personality has therefore received considerable attention, yet some methodological issues remain unresolved. We tested whether assessing personality by...

Animal habituation is key to obtain reliable data on behavioural studies but detailed procedures to achieve it are scarce. This study designed a set of actions to habituate sheep and goats to human observers. Pelibuey...
