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. 

In the zoo environment, anthropogenic noise is common as sound levels fluctuate due to visitors, construction, habitat design, and special events. In this study, changes in the mood of three species of zoo-housed primates in...

Husbandry procedures are necessary for different purposes in horse breeding. The aim of the present study was to assess the aversiveness and effects on the horse-human relationship of a range of common husbandry procedures, in...

This paper describes a method in which horses learn to communicate by touching different neutral visual symbols, in order to tell the handler whether they want to have a blanket on or not. Horses were...

During mildly aversive healthcare procedures, horses often exhibit behaviors that may interrupt or prolong the procedure. Handler response often includes increased restraint and/or positive punishment, which can be ineffective or counterproductive. The purpose of this...

Our goal was to improve dog socialization by increasing novel human interactions, while also providing non-animal care staff opportunity to interact with the dogs. Our volunteer dog socialization program was developed to explore the possibility...

Despite the growing interest in research on the interaction between humans and dogs, only a very few research projects focus on the routines between dogs and their owners. In this study, we investigated one such...

Back disorders are amongst the major health-related disorders associated to working conditions in our society. Horses share with humans the exposure to potential physically harmful working conditions leading to back disorders. However, despite their high...

This paper describes the use of a validated quality of life assessment tool (described elsewhere) to identify environmental and management factors that may affect quality of life in dogs kennelled in rehoming centres. Dogs were...

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 effect of animal-assisted activities (AAA) on the animal participants has been minimally investigated, and the welfare of these animals has been questioned. To enhance our understanding of these animals’ welfare, we measured cortisol collected...

For anyone who has housed rabbits in an artificial plastic environment, what to provide as a nonfood enrichment can be an issue. Nonfood enrichment, or environmental enrichment, can be any toy, engaging sights or sounds...

Captivity often limits a primate’s ability to make meaningful choices on a daily basis. Effective captive (behavioral) management programs should provide primates with opportunities to make meaningful choices. In the present study, arthritic chimpanzees were...

The purpose of this study was to evaluate the influence of housing conditions on daily rhythm of total locomotor activity in dogs. Seven clinically healthy dogs (Canis familiaris) were used and divided into two groups...

Housing in an animal shelter is a stressful experience for dogs. This study examined the effects of different forms of human interaction on concentrations of circulating cortisol and stress-related behaviors of dogs within 40 h...

In captive animal facilities, human staff members are a relevant part of the animals’ social environment in addition to providing care and managing the social group. Structured, predictable interactions and relaxed, spontaneous contacts may all...

Since opening in 2008, a consistent observation has been that the dogs are significantly quieter and easier to handle in their new surroundings in comparison to the old facility. This may be due to specific...

Humans in a negative emotional state are more likely to judge ambiguous stimuli as negative. In recent years, similar judgement biases have been found in some non-human animals that were exposed to long-term or short-term...

This book focuses primarily on human kindness and compassion rather than on human cruelty, callousness, indifference, and egocentric endeavors. It is common knowledge that many lay people and professional researchers treat animals in their charge...

Routine laboratory procedures can be stressful for laboratory animals. We wanted to determine whether human handling of adult rabbits could induce a degree of habituation, reducing stress and facilitating research-related manipulation. To this end, adult...

Animal care for nonhuman primates (NHPs) in biomedical facilities has undergone major changes in the past few decades. Today, most primate facilities have dedicated and highly trained animal care technicians who go to great efforts...

The use of dogs in research has been under increasing public scrutiny and criticism over the past several years, and our institution has been no exception. Of particular concern is the use of Class B...

Comprehensive enrichment programs for dogs, while not required by regulations, are becoming more common in research facilities. Many institutions are providing chewable enrichment devices and pair or group housing for their canine colonies. Human interaction...

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...

At Huntingdon Life Sciences, we have developed a program to meet the exercise and socialization needs of our canines. Our program, entitled "Zen Pen" is a 30-minute weekly play session with at least two technicians...

A central question in the interspecific human/animal relationship is how domestic animals perceive humans as a significant element of their environment. In this study, we tested the hypothesis that the use of positive or negative...
