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. 

Specifically designed restraint chairs are the preferred method of restraint for research studies that require NHP to sit in place for sustained periods of time. In light of increasing emphasis on refinement of restraint to...

Stereotypic behaviors are commonly observed in domestic equids as they are in a range of captive nondomesticated species. Estimates suggest that 19.5%-32.5% of horses perform a stereotypy. The presence of these behaviors is thought to...

When engaging in procedures that horses may find aversive, restraint methods are often used to help ensure safety of both horse and handler. Twitching is a common restraint method, but its use is sometimes considered...

Reviews of existing literature on topics that have been neglected, such as the subject of the cognitive and affective abilities of cows, are productive and necessary exercises in science (Elwen, Findlay, Kiszka, & Weir, 2011...

Domestic cows (Bos taurus) are consumed worldwide as beef and veal, kept as dairy product producers, employed as draft animals in labor, and are used for a long list of other products, including leather and...

Hair plucking has been observed in many captive primate species, including the great apes; however, the etiology of this behavioral pattern is poorly understood. While this behavior has not been reported in wild apes, an...

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...

The quality of the relationship between cattle and their caretakers is important for animal welfare and productivity. Nevertheless, the influence of gentle interactions on group-housed dairy calves has not been thoroughly studied so far. We...

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...

I examined human-animal relationships (HARs) in zoo-housed orangutans (Pongo abelii) and gorillas (Gorilla gorilla gorilla) to see if they followed patterns similar to conspecific relationships in great apes and humans. Familiarity and social relationships guide...

The influence of several factors on abnormal behaviour was investigated in 46 singly housed sooty mangabeys (Cercocebus atys) (eight nursery-reared, 38 mother-reared), including self-injurious, self-directed, stereotypic locomotion, and faeces/urine-related behaviours (SIB, SDB, SL, FUR, respectively)...

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...

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 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...

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...

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...

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...
