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...

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...

The management of socially complex species in captivity is challenging. Research on their social behavior improves our understanding of interactions in captive animals and captive-group management. We conducted a detailed analysis of social relationships shown...

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...

The field of zoo animal welfare science has developed significantly over recent years. However despite this progress in terms of scientific research, globally, zoo animals still face many welfare challenges. Recently, animal welfare frameworks such...

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...

Marine mammals include cetaceans, pinnipeds, sirenians, sea otters and polar bears, many of which are charismatic and popular species commonly kept under human care in zoos and aquaria. However, in comparison with their fully terrestrial...

Many comparative studies have focused on the emergence of solitary and social play in early development, however, few consider observer and parallel forms of play. In this study, we analyzed approximately 21 h of video recordings...

Indoor housing of cats is associated with a higher incidence of multiple diseases, including obesity. Increased exercise is often recommended as a method of creating or increasing the negative energy balance required for weight loss...

Cats living inside a home without any possibility of outdoor access have to defecate in a litter box. To suit the cats' needs, several recommendations seem to be agreed upon. The litter box has to...

Rabbits are known to be finicky about food and will reject it based upon several factors: odor, texture, form, or method of presentation. It can be an even greater challenge to get rabbits to eat...

Although the number of rabbits (Oryctolagus cuniculus) produced in Europe is important, they are under-represented in welfare research. Studies on the effects of housing conditions have focused on performance and mortality. We conducted a meta-analysis...

The RSPCA/UFAW Rodent (and now Rabbit) Welfare Group held a one-day meeting on 1 November 2016 at the University of Edinburgh and was attended by 70 delegates. Presentation topics included refinements in blood sampling rodents...

Few studies have sought to describe cat elimination behavior in detail and much of the information presently available focuses on factors that potentially cause cats to reject a litter box. Thus, the ethograms published in...

Performance of abnormal repetitive behavior (ARB) is noted in many captive wild species. ARB can be categorized into 2 basic forms: those whose aim appears to be to compulsively reach an inappropriate goal and those...

The RSPCA/UFAW Rodent Welfare Group has held a one-day meeting every autumn for the last 21 years, so that its members can discuss current welfare research, exchange views on rodent welfare issues and share experiences...

Knowledge of the organization and dynamics of the relationships between animals and the environment and its resources is important to meet the needs of any species. We analyzed the effect the presence of a person...

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...

Dietary composition and presentation impacts on the behaviour of animals, and failure to provide a suitable diet can lead to reduced welfare through the development of poor health, the inability to express normal behaviours and...

Surveillance of cat shelters by official veterinarians in Austria is based on legal requirements and does not directly assess cat welfare. The aim of this study was to develop animal-based parameters that are feasible to...

Across the animal kingdom, immature animals are characterized by their playfulness and diversity of behavior, but are their actions enriching to adult conspecifics? The purpose of this study was to assess if beluga (Delphinapterus leucas)...

The most common housing system for reproduction rabbits, individual cage housing on a wire floor, is increasingly scrutinized because of its potential detrimental impact on animal welfare. We compared three types of housing: (1) individual...

Understanding environmental factors that affect the behavior of cats in cages is important if caretakers are to improve the welfare of confined cats. The aim of this study was to examine the effects of the...

Play is an important aspect of dolphin life, perhaps even an essential one. Play provides opportunities for dolphin calves to practice and perfect locomotor skills, including those involved in foraging and mating strategies and behaviors...
