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 RSPCA/UFAW Rodent (and now Rabbit) Working Group has held a one-day meeting every autumn for the last 25 years, so that its members can discuss current welfare research, exchange views on welfare issues and...

The presentation I gave at IAT Congress 2019 was based on the changes and refinements the University of Dundee, Medical School Resource Unit (MSRU) has made over the past 18 months. These changes, described in...

Underwater sound fields can be complex, both in open water and small tank environments. Here we measured 1) spatial variation in artificially elevated sound levels in a small fish tank for both particle motion and...

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...

Dairy calf welfare concerns are growing and new evidence suggests that the early life environment influences appropriate physical, behavioral, and cognitive development lasting into adulthood. This review highlights key evidence for the impacts of housing...

In this review, we focus primarily on the refinement of common methods used in fish research based on emerging knowledge with the aim of improving the welfare of fish used in scientific studies. We consider...

When environmental temperatures exceed 25°C, horses are potentially subjected to thermal stress. It has therefore been recommended that horses should be provided with shade during hot days. However, this is not possible for horses grazing...

“Pheromonal therapy” has been promoted as a promising alternative therapy to improve the human-animal relationship and to reduce behavioral reactions to stressful stimuli. This placebo-controlled double blind study evaluated the use of a synthetic equine...

Dogs form toileting preferences that may influence canine elimination behaviors. This study aimed to assess the effect of providing a novel substrate (synthetic grass) on indices of canine willingness to eliminate, plus associated behavioral parameters...

Icelandic horses are often stabled in loose-housing systems, and to date this type of stabling has not been evaluated with regard to its potential impact on respiratory health. The objective was to assess if differences...

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...

Past research has indicated that horse hooves change shape in response to gallop exercise, so this study sought to separate the changes due to exercise from changes due to wearing horseshoes. This crossover study tested...

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...

Cephalopods have become an archetype for invertebrate cognition, sentience and welfare studies. Their convergence with so-called ‘higher’ vertebrates (birds, mammals) in memory, learning, problem-solving, tool use and likely sentience has made biologists completely rethink the...

Honey bee (Apis mellifera) colonies are “superorganisms”. Individual bees do not display the complete behavioural and ecological range of the species. With its caste structure and division of labour, the colony acts as a functional...

Indicators of positive emotions are still scarce and many proposed behavioural markers have proven ambiguous. Studies established a link between acoustic signals and emitter’s internal state, but few related to positive emotions and still fewer...

Rotifers are now becoming a standard live feed for first-feeding larvae, because of their easy rearing protocol and improved growth and survival rate, compared with other fish feed, paramecia, and processed powder fish feeds. In...

Evaluation of kennel flooring surfaces is needed to understand their impacts on dog health and well-being. This pilot study aimed to characterize aspects of physical health, kennel cleanliness, and dog body cleanliness on flooring types...

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...

The RSPCA/UFAW Rodent (and now Rabbit) Welfare Group held a one-day meeting on 14 November 2017 in Weybridge, UK. The first session addressed meeting animals' needs and aiming for a 'good life', with the needs...

This work aimed at evaluating the effects of housing system, pen floor type, and lactation management on rabbit doe and kit performance throughout a reproductive cycle, including categorization of aggressiveness and injuries. Forty multiparous pregnant...

Greyhounds are routinely bred and managed for racing and are usually housed in individual kennels. To address the question of whether greyhounds would benefit from an increase in the minimum kennel size specified in the...

The temporal distribution of feeding behaviour is of primary importance in grazing herbivores. Many domestic horses are managed under conditions far removed from the natural environment. For example, restricted access to roughage may induce health...

We investigated whether nest building and nest site preference are temperature dependent in female mink. We designed two experiments: in Experiment 1, female mink had access to unheated (7 °C, Room7C group) or heated (25...

Brycon amazonicus shows a high frequency of aggressive behavior, which can be a limiting factor in intensive farming systems. Environmental changes can modulate the social interactions of fish and reduce aggression during the different stages...
