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. 

Biotelemetry can contribute towards reducing animal numbers and suffering in disciplines including physiology, pharmacology and behavioural research. However, the technique can also cause harm to animals, making biotelemetry a ‘refinement that needs refining’. Current welfare...

Although rabbit does are generally single housed on rabbit farms worldwide, it has been suggested by some specialists and recommendation of organic rabbit production systems that group housing of does is more comfortable and similar...

Primates are notable for having a rich and detailed understanding of their social environment and there has been great interest in the evolution and function of social knowledge in primates. Indeed, primates have been shown...

Physiological and psychological effects of listening to music have been documented in humans. The changes in physiology, cognition and brain chemistry and morphology induced by music have been studied in animal models, providing evidence that...

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...

Foraging opportunities are a key component of enrichment in captive nonhuman primates (NHP) providing manipulative opportunities in which animals can engage in species-typical behaviors. Recent studies suggest captive NHP populations have increased body weight over...

Chronic pain and distress are universally accepted conditions that may adversely affect an animal’s quality of life (QOL) and lead to the humane euthanasia of an animal. At most research institutions and zoological parks in...

Although alopecia in captive baboons has previously been assessed, the incidence of alopecia in large groups of baboons housed in more expansive outdoor settings has not been evaluated. The purpose of this study was to...

A cooperative environment is paramount when working with nonhuman primates (NHP). Desensitization to specific stimulus helps to allow technicians to more safely perform procedures without the use of anesthetics, and with minimal restraint, greatly reducing...

The eighth edition of the Guide for the Care and Use of Laboratory Animals (the Guide) states that appropriate social interaction among members of the same species is essential for normal animal development and wellbeing...

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...

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...

Cats can be successfully housed in groups when given enough space in addition to sufficient feeding, elimination, and resting areas. Cats at the University of Rochester are utilized in vision research, and have titanium cranium...

Rabbit hypnosis or “trancing” was a common restraint technique used for minor procedures such as: nail clipping, tooth trimming, eye exams, and subcutaneous injections. In years past the technique was originally used on pet rabbits...

The impact of operantly training domestic cats to accept jugular blood collections in a dorsally recumbent (novel) position was assessed. Cats were assigned to one of three groups: Group 1 (N = 14): no training...

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...

As research subjects, cats have contributed substantially to our understanding of biological systems, from the development of mammalian visual pathways to the pathophysiology of feline immunodeficiency virus as a model for human immunodeficiency virus. Few...

The authors describe various methods of handling and restraining rabbits, and propose that while many methods are appropriate, rabbits respond better if only one method is used consistently.

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...

Reptiles and amphibians have been neglected in research on cognition, emotions, sociality, need for enriched and stimulating environments, and other topics that have been greatly emphasized in work on mammals and birds. This is also...

This very well illustrated, informative book is divided into the following chapters: (1) Why do we use primates in research? (2) Primate species we use. (3) History of medical advances. (4) Areas of research. (5)...

The effect of the provision of simple objects to stabled horses on their behaviour was investigated to determine whether these objects can affect horses' behaviour in a positive way and thus enrich their environment. A...

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.

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...

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...
