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. 

Beef cattle may be fattened before slaughter using a high-energy, grain-based diet. Although previous research suggests cattle prefer grain, their motivation to obtain this feed has not been quantified. The objective of this study was...

Separating calf and cow within 24h after birth is common practice in dairy farms. Some dairy farmers, however, practice a rearing system in which the calves are nursed by their dam or by foster cows...

Motivation to explore is believed to be widespread among animals, but exploratory behaviour varies within populations. Offering variety in feed is one simple way of allowing intensively housed dairy cattle to express exploratory foraging behaviour...

The objective was to investigate the effect of placing mats on concrete slatted floors on performance, behaviour, hoof condition, dirt scores, physiological and immunological variables of beef steers, and to compare responses with animals on...

Reproducibility in animal studies has been defined as the ability of a result to be replicated through independent experiments within the same or among different laboratories. Over the past few years, much has been written...

A common dilemma faced by all animal bioethics committees arises when exceptions are proposed to the use of analgesics in painful procedures. The committee and researcher must weigh the possible confounding effects of including additional...

In the US, the Animal Welfare Act (AWA) and its enabling regulations (AWAR) cover all warm-blooded animals used for research, testing, experimentation, or exhibition. The only exceptions, made in the enabling regulations, are for two...

Performance of abnormal repetitive behavior (ARB) is noted in many captive wild species. ARB can be categorized into 2 basic forms: those whose aim appears to be to compulsively reach an inappropriate goal and those...

The compost bedded pack barns is a loose housing confinement system for dairy cows, which aims to provide greater comfort in the resting area. Therefore, objective of this review was to investigate the environment, behavior...

Contentious issues in calf rearing include milk feeding level and single versus group housing. The current study was performed on a high-producing 170 Holstein cow dairy farm to investigate the impact of nutrition and housing...

Staggering food availability through a delivery device is a common way of providing behavioural enrichment as it is usually thought to increase the amount of natural behaviour due to the unpredictability of the food source...

Guidance is almost non-existent as to suitable levels of UV lighting for reptiles and amphibians, or how to achieve satisfactory UV gradients using artificial lighting. The UV-Tool is a working document that seeks to address...

Outdoor access is often cited as a critical component of appropriate housing for great apes in captivity, and although studies have shown that offering primates choices can improve welfare, choice to access specific areas has...

Replacement, Reduction and Refinement, the Three Rs of Russell & Burch, are accepted worldwide as fundamental to the ethics of animal experimentation. The production, care and use of genetically-altered animals can pose particular challenges to...

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...

Originally enacted in 1966, the Laboratory Animal Welfare Act has been amended several times and renamed the Animal Welfare Act. Responsibility for administering the Animal Welfare Act was delegated within the United States Department of...

Wooden objects are often used as nonhuman primate enrichment to provide variety and novelty, promote exploratory behavior, and supply an outlet for curiosity. However, concerns have been raised regarding the ability to sanitize wood by...

High levels of ambient noise can have detrimental effects on laboratory animal wellbeing and may affect experimental results. In addition, excessive noise can reduce technician comfort and performance. This study was performed to determine whether...

Most regulations governing animal experimentation require that the harms expected to be incurred by animal subjects should be balanced against the likely benefits of the project. Too often, however, expected human benefits are based on...

A respected resource for decades, the Guide for the Care and Use of Laboratory Animals has been updated by a committee of experts, taking into consideration input from the scientific and laboratory animal communities and...

Enrichment devices are administered to laboratory animals to reduce abnormal behaviors and to promote species typical behaviors (for example, foraging and nest building). With a diverse collection of species that require numerous enrichment options, a...

To do justice to the diverse approaches to enrichment and behavioral management around the world would entail a discussion beyond the limits of this publication. Therefore, guidelines and regulations in a representative sample of countries...

These guidelines aim to provide information for investigators, animal care committees, facility managers and animal care staff that will assist in improving both the care given to farm animals and the manner in which experimental...

The regulation of the use of animals for experimental and other scientific purposes and the determination of minimum required standards of animal care and accommodation within Europe is generally informed by recommendations and conventions at...

In Japan, the Architectural Institute of Japan (AIJ) provides guidelines for laboratory animal facilities and equipment. Guidelines are not legally binding but serve as the authority for proper facilities and equipment management. The first guideline...
