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. 

Knowledge of the organization and dynamics of the relationships between animals and the environment and its resources is important to meet the needs of any species. We analyzed the effect the presence of a person...

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...

Every day, millions of domestic cats are held temporarily in captive environments, such as boarding catteries and rescue shelters. Being in confinement can potentially invoke high levels of stress for these animals. Therefore, there is...

A central question in the stockman-animal relationship is how animals perceive humans depending on previous interactions with them. This study aimed at measuring the influence of a previous experience with humans on subsequent reactivity to...

Early handling of animals including tactile stimulation (TS) has been shown to have beneficial effects on the physical and psychological development of species where considerable maternal interaction, e.g. in the form of licking, already occurs...

The ability of positive affective states to counteract negative states engendered by routine medical procedures remains poorly studied. In laboratory rats, positive affect typically associated with rough-and-tumble play can be induced through human “hand play”...

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...

Many laboratory mice used in research experience spontaneous seizures during cage changing and routine handling. The triggers are usually the abrupt sound and sudden motion of the cage. These seizures can range from mild to...

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...

Social or group housing is well known as the ideal environment for maintaining cats in a research setting as it allows specific behaviors such as play, grooming, and climbing. When social housing is not possible...

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...

Appropriately accommodating the pig's normal social behavior is an essential step in protecting its well-being in managed environments. Doing so is particularly important in laboratory settings in which distress due to social isolation and other...

Medical care of nonhuman primates in a laboratory setting can be challenging due to the safety concerns inherent in handling conscious animals. A mature, adult male cynomolgus macaque presented with a chronic foot condition that...

Social interactions during adolescence are important especially for neuronal development and behavior. We recently showed that positive emotions induced by repeated tickling could modulate fear-related behaviors and sympatho-adrenal stress responses. In the present study, we...

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...

Social housing is recommended for laboratory rats because they are highly social mammals but research constraints or medical issues often demand individual housing and, when social housing is practiced, it typically involves housing with only...

Raising entire males is already common in a few European countries. It has the advantage of avoiding the pain of castration. Entire males have also a better food conversion. However, they would be more aggressive...
