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. 

This report describes what rabbits need in terms of social housing, enclosure size and type, and environmental enrichment. It also describes potential husbandry-related welfare problems and how to resolve them.

Studies have shown chimpanzees can learn to perform tasks by watching live or videotaped demonstrators. The present study assessed whether female chimpanzees exposed to a videotaped demonstrator would learn a husbandry-related task, urinating into a...

Chimp Haven has retired 153 chimpanzees, the majority from biomedical research, and abnormal behavior patterns have been reported. Abnormal behaviors are well described in chimpanzees and usually related to early rearing environment, social isolation and...

The ability to provide permanent group-housed caging for nonhuman primates involved in toxicology research is quickly becoming an important step in improving the overall quality of life for these animals. This type of caging offers...

Maintaining the psychologic wellbeing of nonhuman primates housed in a laboratory setting is an important aspect in providing the best possible care for these animals. Nonhuman primates kept in captivity can begin to display abnormal...

COST Action B-24 established four working groups to research and discuss issues relevant to laboratory animal science. These included the housing of animals, environmental needs, refinement of procedures, genetically modified animals, and cost-benefit analysis. Based...

The Biology and Medicine of Rabbits and Rodents provides concise, up - to - date, reasonably comprehensive information to anyone concerned with the health, care, and management of rabbits and rodents. The book is intended...

Refinement of animal care and housing is an important shared goal - and challenge - of the team of research, veterinary, and animal care personnel charged with ensuring the wellbeing of laboratory animals. This study...

Veterinary technician Evelyn Skoumbourdis and environmental enrichment coordinator Casey Coke Murphy discuss proper feeding of small laboratory mammals.

Obesity is a concern with nonhuman primates (NHPs) housed in captivity for extended periods of time, mostly due to overfeeding and lack of exercise. This is often compounded by environmental enrichment programs that include different...

Self-injurious behavior (SIB) can result in open wounds, tissue damage, and increased risk of infection. In many cases, increased environmental enrichment is not consistently effective in eliminating this behavior. We report here on the successful...

Provision of shade to dairy cattle in summer can alleviate negative effects of heat stress. The aim of this study was to investigate the relative importance of shade to lactating dairy cows in different ambient...

The report sets out how to provide: optimal enclosure characteristicsand size; social housing; solid flooring and substrate; raised areas; refuges; gnawing objects and dietary enrichment; positive interaction with humans; toys and objects to manipulate; for...

The aim of the experiment was to study the effects of cage density (1, 3 and 5 rabbits per cage) and sex (male and female) on stress parameters of young rabbits. A total of 90...

This article provides details to consider when preparing to use animals in biomedical research. The stress of transport and receipt of animals into a new environment mandate the need for a period of stabilization and...

Many aspects of the research animal's housing environment are controlled for quality and/or standardization. Of recent interest is the potential for environmental enrichment to have unexpected consequences such as unintended harm to the animal, or...

Evidence indicates that allowing beef calves to stay in the maternal herd beyond the age of natural weaning promotes animal welfare and may enhance the cows' natural reproductive potential.

A device was designed that allows us to blow forage [e.g., chicken scratch] into both empty and occupied cages and over a wide area.

The objective of toxicology and pharmacology studies is to detect change or variation from normal and to interpret the significance of such change, with the intention of assessing risk to man. With non-human primates (NHPs)...

The purpose of this study was to link abnormal behaviors often expressed by chimpanzees living in captive environments to factors related to their care and housing. Individuals who had spent more time with their mothers...

Training technique is described. Thirty-seven [group-housed] captive chimpanzees were trained using operant conditioning to enter a transfer box. [Age and sex of subjects is not provided.]

Review of the implications of experimental or management-related manipulations of the social environment of captive primates for the animals' welfare. Relatively little empirical work has been done on the effects of manipulation of the social...

The use of woodchips as bedding for 16 juvenile chimpanzees (Pan troglodytes) was evaluated for the effects on behaviour, health and husbandry practices. Woodchip bedding was placed in two outdoor play areas for five consecutive...
