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. 

When engaging in procedures that horses may find aversive, restraint methods are often used to help ensure safety of both horse and handler. Twitching is a common restraint method, but its use is sometimes considered...

Orang-utans are the largest mainly arboreal animal: wild orang-utans rarely come to the forest floor. In contrast, the locomotion behaviour of captive orang-utans encompasses more time on the ground and they spend less time on...

We have an ethical and scientific obligation to Refine all aspects of the life of the laboratory-housed dog. Across industry there are many differences amongst facilities, home pen design and husbandry, as well as differences...

Literary fiction has been credited with considerable power to improve attitudes toward outgroups. It was even argued that it has been an important factor behind the global decline of violence against various minorities in the...

Improving the welfare of nonhuman animals in captivity and maintaining behavioral competence for future conservation purposes is of the highest priority for zoos. The behavior of an aggressive male drill (Mandrillus leucophaeus poensis) was assessed...

Domestic guinea pigs (Cavia aperea f. porcellus) in laboratories have been shown to actively avoid the centers of their cages. This experiment tested a novel, dark-colored “shader” placed over the central portion of a cage...

Fecal corticosterone concentration (FCC) was measured in 14 buck rabbits individually housed in standard-dimension cages (SC) or in bigger cages (BC; with a volume more than double that of SC and equipped with a plastic...

From May- July 2014, I conducted research within a private spider monkey sanctuary, Ecoparque el Fenix, in Campeche, Mexico, home to 20 spider monkeys obtained from the illegal pet trade. Limited financial resources had resulted...

This poster is based on welfare improvements gained from group housing rabbits in floor pens in the new Antibody Production Facility with a focus on development, behaviours and environmental enrichment in both male and female...

Monkeys first arrived in the Comparative Biology Centre (CBC) at Newcastle University in 2000. They were housed in three small separate units consisting of steel and wooden cages. In 2011 a decision was made to...

Cows on two separate farms were submitted to a 6 d preference test, repeated four times, consisting of three 2 d phases (3 h d−1 phase−1): forced-indoor, forced-outdoor, and free-choice. A majority of cows on...

The captive environment of a laboratory animal can profoundly influence its welfare and the scientific validity of research produced. The African clawed frog (Xenopus laevis) is a common model organism, however current husbandry guidelines lack...

This paper describes a method in which horses learn to communicate by touching different neutral visual symbols, in order to tell the handler whether they want to have a blanket on or not. Horses were...

Undesirable behavior (e.g. biting, kicking and aggression) during handling is a growing concern in the equine industry, and is likely to compromise horse-human relationships. The present study, carried out over 3 months, investigated the expression...

During mildly aversive healthcare procedures, horses often exhibit behaviors that may interrupt or prolong the procedure. Handler response often includes increased restraint and/or positive punishment, which can be ineffective or counterproductive. The purpose of this...

In order to give individually housed stallions the opportunity to have more social interactions, the Swiss national stud farm investigated a separation wall called ‘social box’. Sixteen adult Franches-Montagnes breeding stallions were housed for 3...

Laboratory dogs should be sociable with humans and react in a relaxed way when confronted with new stimuli and situations. This is of particular advantage when dogs are used in animal experiments and for the...

Our goal was to improve dog socialization by increasing novel human interactions, while also providing non-animal care staff opportunity to interact with the dogs. Our volunteer dog socialization program was developed to explore the possibility...

In order to provide research dogs enrichment at our facility, veterinary staff suggested adapting the adjacent space to our dog housing buildings to allow for more species-specific behavior by creating an exercise area that both...

At Pfizer’s Pearl River site, rabbits are socially housed in pairs or triples in dog runs that have been converted into rabbit pens. The daily husbandry and maintenance of these pens, however, proved to be...

Despite the growing interest in research on the interaction between humans and dogs, only a very few research projects focus on the routines between dogs and their owners. In this study, we investigated one such...

Back disorders are amongst the major health-related disorders associated to working conditions in our society. Horses share with humans the exposure to potential physically harmful working conditions leading to back disorders. However, despite their high...

The separate influences of spatial density and housing quality on the behavior of captive animals are difficult to measure because the two factors are often intrinsically linked. Here, we recorded affiliative and agonistic behavior in...

The quality of the relationship between cattle and their caretakers is important for animal welfare and productivity. Nevertheless, the influence of gentle interactions on group-housed dairy calves has not been thoroughly studied so far. We...

This paper describes the use of a validated quality of life assessment tool (described elsewhere) to identify environmental and management factors that may affect quality of life in dogs kennelled in rehoming centres. Dogs were...
