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. 

Social enrichment is increasingly employed to improve the welfare of laboratory animals, including rabbits. However, the high levels of injurious aggression that can occur when unfamiliar adult rabbits are introduced to one another are a...

Goat enrichment can be incredibly rewarding, not only for the goat, but for personnel as well. In our facility, we often refer to goatenrichment tasks as technician (or vet!) enrichment. Somewhere in the evolutionary development...

As a goat's separation from or reintegration into its group is likely to have an adverse effect on the welfare of both the separated goat and the remaining goats in the group, management procedures need...

We analyzed our current enrichment protocols in order to develop and implement social experiences for our rabbit and guinea pig colonies. This article describes the development of an exercise pen for rabbits and a custom-made...

On Swiss rabbit breeding farms, group-housed does are usually kept singly for 12 days around parturition to avoid pseudogravidity, double litters and deleterious fighting for nests. After this isolation phase there is usually an integration...

Abnormal behavior in macaque monkeys has been associated with risk factors such as nursery rearing and single housing. However, less is known about the extent of, and risk factors for, abnormal behavior in baboons. The...

Despite growing interest in promoting positive welfare, rather than just alleviating poor welfare, potential measures of good welfare, and means to provide it, have remained elusive. In humans social support improves stress-coping abilities, health, and...

Since we receive rabbits at 10-12 weeks of age and we only house them for about 3 to 4 weeks, we decided to give group housing a try. Change is hard for most people and...

Lean management-based visual tools have been used to improve the quality of animal care associated with a complex research study involving immune-compromised cynomolgus monkeys (M. fascicularis) in various postsurgical recovery states. In order to effectively...

There is a general consensus among those studying the welfare of captive primates that social housing is the most effective means for promoting psychological well-being. It is well established that socially-housed rhesus macaques (Macaca mulatta)...

Zebrafish are a widely utilised animal model in developmental genetics, and owing to recent advances in our understanding of zebrafish behaviour, their utility as a comparative model in behavioural neuroscience is beginning to be realised...

In captive research environments for nonhuman primates (NHP), social housing strategies are often in conflict with protocols designed to minimize disease transmission. This is particularly true in breeding colonies, and is especially relevant when attempting...

The RSPCA/UFAW Rodent Welfare Group holds a one-day meeting every autumn so that its members can discuss current welfare research, exchange views on rodent welfare issues and share experiences of the implementation of the 3Rs...

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.

The physiologic and anatomic structure of rabbits can cause high mortality rates in rabbit oral gavage. Rabbits are capable of a wide variety of jaw movement due to 3 jaw-closing muscle groups (masseter, temporalis, pterygoid)...

Standard rabbit caging offers little in the way of exercise, vertical space for species-typical movements (that is, standing on hind limbs), or ample space for proper social introductions. One commonly used rabbit breed, the New...

While female rabbits can be safely cohoused, aggression and resulting fight wounds preclude cohousing males. However, males may still benefit from social enrichment. Currently no housing systems provide males a safe opportunity for social interaction...

It is widely recognised that single housing is detrimental to the welfare of social species. However, some experimental procedures dictate that laboratory animals are housed individually. There is evidence to suggest that, by mimicking social...

The veterinary staff at our facility has been working to pair house the female New Zealand white rabbits in our training colony. These rabbits range in size, age, and temperament, which can make finding potential...

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...

Only social contact satisfies the goal of promoting a wide variety of species-typical activities while at the same time reducing or preventing the development of abnormal behavior... A number of toys should be provided initially...

This article provides a brief historical background of the events and circumstances that led to the 1985 Animal Welfare Act (AWA) amendments. It describes the development of the regulations promulgated by the US Department of...

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...

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)...
