Refinement Database

Database on Refinement of Housing, Husbandry, Care, and Use of Animals in Research

This database, created in 2000, is updated every three months with newly published scientific articles, books, and other publications related to improving or safeguarding the welfare of animals used in research.

Links to the full text for publications that appear in open access journals or are published on the AWI website are provided under the abstract.

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 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. Most publications older than 2010 can only be searched by keyword. 
Accelerometers offer unique opportunities to study the behaviour of cryptic animals but require validation to show their accuracy in identifying behaviours. This validation is often undertaken in captivity before use in the wild. While zoos...
Aspects of the laboratory are aversive to mice, such as being housed under bright lights and at temperatures below their thermal comfort, causing stress and poor welfare. While murine thermal preferences are well understood, light...
Exposure of sentinel mice to dirty bedding is commonly used in health monitoring programs to screen colonies for clinical and subclinical disease. Despite the potential stressors present in dirty bedding, including but not limited to...
Gel solutions are simple to use, have a relative long shelf life and can be delivered with plastic cups or pouches. A common issue encountered by many institutions is that the gel becomes soiled quickly...
Across a period of 54 months, several changes were made to the feeding protocols of 32 adult chimpanzees living at the Yerkes National Primate Research Center Field Station. Before implementing any changes in diet, baseline...
The RSPCA/UFAW Rodent Welfare Group has held a one-day meeting every autumn for the last 28 years, so that its members can discuss current welfare research, exchange views on welfare issues and share experiences of...
Ambient temperature is an important non-biotic environmental factor influencing immunological and oncological parameters in laboratory mice. It is under discussion which temperature is more appropriate and whether the commonly used room temperature in rodent facilities...
Horses are commonly trained using negative reinforcement. However, a growing body of scientific evidence supports positive reinforcement as an efficient training method for horses. In this study we investigated the effects of adding a small...
National legislation requires shelter access for horses kept outside during winter, whereas there are no requirements for shelter access to provide shade and a refuge from biting insects during summer. This study investigated use of...
Despite donkeys being involved in various activities with humans, their cognitive and learning abilities are still little known. A deeper understanding of their perceptive, cognitive and learning processes is, thus, necessary to preserve their well-being...
This study aimed at evaluating the effects of unpredictability on behavioral and clinical aspects of Geoffroy's woolly monkey (Lagothrix cana cana) - a frugivorous Amazonian primate species - under human care. We studied seven individuals...
Rodents used for research can be humanely housed in a variety of ways. As such, a vast number of different housing environments are used, but are often not described in research publications. However, many elements...
Routine health monitoring is an integral part of managing SPF rodent colonies. In recent years, rack-level environmental sampling has been introduced as an adjunct method or replacement for exposure of sentinel rodents to soiled bedding...
Naked mole rats (Heterocephalus glaber) are a unique rodent species originating in Africa and are increasingly being used in research. Their needs and characteristics differ from those of other rodents used in research. Unique housing...
Sociocultural changes in the human–animal relationship have led to increasing demands for animal welfare in biomedical research. The 3R concept is the basis for bringing this demand into practice: Replace animal experiments with alternatives where...
Since they arrived at CU Boulder, we have learned a lot about the voles from the laboratory, other institutions, and our trial-and-error. We hope this information can be helpful to any considering adding voles to...
Naked mole-rats (NMRs) have unique husbandry requirements that need to be considered when maintaining them in captivity. We have successfully maintained NMRs at the University of Illinois at Chicago for more than 20 years. This...
In the event of an emergency resulting in our automatic watering system being shut off, we identified the need to increase the number of rodent water bottles we have on hand. Once we realized we...
Mice respond to a cage change (CC) with altered activity, disrupted sleep and increased anxiety. A bi-weekly cage change is, therefore, preferred over a shorter CC interval and is currently the prevailing routine for Individually...
Although nesting material is beneficial to the welfare of laboratory mice, provision of appropriate amounts may impair visualization of the mice. In anticipation of our academic research institution transitioning to providing 6 grams of nesting...
The combination of bedding substrate and nesting material within the microenvironment of mice is an important consideration for animal care programs in regard to optimizing animal wellbeing. We used 3 general or breeding mouse colonies...
Ammonia control is an important characteristic of rodent bedding materials. Among natural bedding materials, corncob bedding provides excellent ammonia control but contains estrogenic compounds and is ingested by mice. By comparison, processed cellulose bedding products...
Whether you are an animal care/husbandry technician, facility manager, or veterinarian, everyone bemoans a leaky drinking valve (often referred to as a lixit). Leaking drinking valves and flooded cages are a fairly common problem when...
Horse practitioners have difficulties with undesirable behaviors exhibited by their horses (Equus caballus), such as cribbing, weaving, or head shaking. It has been suggested that most of behavioral disorders originate from the animals’ attempt to...
Automated touchscreen techniques find increasing application for the assessment of cognitive function in rodents. However, hardly anything is known about the potential impact of touchscreen-based training and testing procedures on the animals under investigation. Addressing...
