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 study of laboratory animal behavior has increased steadily over the last decade, with expanding emphasis on a variety of commonly used species. In the United States, this trend was initially focused on species for...

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...

This is the third volume of discussions that took place on the Laboratory Animal Refinement & Enrichment Forum (LAREF). This forum is dedicated to the exchange of personal experiences of refining the conditions under which...

Husbandry training of zoo animals (training) has been associated with many benefits, and indisputably is a valuable tool; training facilitates movement of animals within their environment, and participation in husbandry and medical procedures. Training has...

In the eighth edition of the Guide for the Care and Use of Laboratory Animals, the recommended rabbit cage height was changed from 14 to 16 in. In contrast, the majority of our rabbit cages...

Clinical Laboratory Animal Medicine: An Introduction, Fourth Edition offers a user-friendly guide to the unique anatomy and physiology, care, common diseases, and treatment of small mammals and nonhuman primates. Carefully designed for ease of use...

The main objective of the program of research, of which this study is part, is to evaluate the housing and environmental enrichment for laboratory rabbits. The aim is to determine whether modifications to basic housing...

Since there is evidence that the bottom cages can impact research, this should be a good reason to eliminate the two-tier system with its species-inappropriate bottom-tier cages.

While clinical reptile medicine as a science is in its ascendancy among veterinary surgeons and other interested groups, familiarity with the often related issue of reptilian behavioural and psychological health appears less common. Behavioural change...

In the last decade several surveys of primate care and training programs highlight a common theme; despite scientific evidence that animal training can be effective in reducing stress, increasing efficiency and improving veterinary care, animal...

Nonhuman primates in research environments experience regular stressors that have the potential to alter physiology and brain function, which in turn can confound some types of research studies. Operant conditioning techniques such as positive reinforcement...

This review will examine how individual differences in temperament might affect, or be affected by, behavioral management practices for captive primates. Measuring temperament may help us predict the outcome of social introductions. It can also...

It is often argued that increasing the amount of control that animals have over various aspects of their environment has a positive effect on their welfare, despite limited empirical evidence. We gave 12 pairs of...

Little information is available on the response of vervet monkeys to different housing conditions or on the suitability of enrichment devices or methods for vervet monkeys. In this study, the authors evaluated the occurrence of...

To enhance the psychological well-being of non-human primates, many biomedical facilities use positivereinforcement training (PRT) techniques to encourage voluntary participation in husbandry and clinical procedures.PRT increases the animal?s control over its environment and desensitizes the...

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...

The aims of this paper are to discuss the most appropriate housing, husbandry routine and enrichment for ferrets .. without compromising science.

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.

At the Oregon National Primate Research Center, we train animals to enter transfer boxes using positive reinforcement training (PRT), a type of training in which the trainer reinforces desired behaviors (such asentering the transfer box)...

In order to prevent physical and psychological deterioration in older animals, it is important to apply the same principles of environmental enrichment and housing as are applied to younger animals. As we have discussed above...

The discussion was started by the following questions: "Is the squeeze-back mechanism more or less stressful than the pole and collar system for removing a macaque from his cage for an IM (intramuscular) injection?" and...

As a global company, our institution made the decision to install European Union (EU) Appendix A-compliant nonhuman primate cages at one of its facilities. This investment represented a substantial evolution of standards commonly employed within...

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...

The Guide for the Care and Use of Animals and the USDA Animal Welfare Regulations (AWR) outline minimum space requirements for laboratory animals, including rabbits. These documents encourage housing of animals in enclosures that allow...

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)...
