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. 

Fish are known to respond to a wide range of irritant chemicals, displaying clear behavioural changes after exposure to potentially noxious stimuli. Recent evidence shows that these agents can have an impact on larval forms...

Recent studies have demonstrated that fish exhibit behavioural responses to noxious stimuli, including mechanical, chemical or thermal stimulation. In many cases, these responses are characterised by a reduction in the locomotor activity, which in turn...

Home Office guidelines recommend the use of analgesics for all protected species, including fish during scientific procedures likely to result in pain, suffering, distress and lasting harm. In larger fish species some drugs have shown...

Behavioural changes associated with cautery disbudding of female Saanen dairy goat kids were assessed. At 4±2days of age, kids were randomly assigned to one of two treatment groups: (i) disbudded with a cautery iron (CAUT...

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...

Stereotypic behavior is an important indicator of compromised welfare. Zoo elephants are documented to perform stereotypic behavior, but the factors that contribute to performance have not been systematically assessed. We collected behavioral data on 89...

Anaesthesia is used daily in fish experimental procedures; however, the use of an inadequate anaesthetic protocol can compromise not only the animal’s welfare but also the reliability of results. The use of zebrafish (Danio rerio)...

A dorsal-fin photo-identification technique paired with a non-invasive parallel laser photogrammetry technique was used to non-invasively identify individual Sphyrna mokarran over time. Based on the data collected over a duration of 59 days, 16 different...

Fur chewing is a behavioral disorder frequently reported in chinchillas kept for fur-farming purposes. Rodents kept in barren cages usually develop some form of abnormal repetitive behavior, which can indicate a past or present welfare...

Positive reinforcement training (PRT) has become a widely used tool in improving the ease with which husbandry and veterinary procedures are performed for animals under human care. PRT provides positive social interaction, cognitive stimulation, and...

Reduced space can lead to crowding in social animals. Crowding increases the risk of agonistic interactions that, in turn, may require additional physiological defensive coping mechanisms affecting health. To determine the stress induced from increased...

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...

Abnormal behavior, ranging from motor stereotypies to self‐injurious behavior, has been documented in captive nonhuman primates, with risk factors including nursery rearing, single housing, and veterinary procedures. Much of this research has focused on macaque...

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...

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...

Non-human primates occasionally exhibit behaviours thought to occur only in captivity that are considered abnormal. In particular, hair-plucking behaviour occurs across many species of mammals and birds. This study was the first to assess the...

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...

Abnormal behavior in macaque monkeys has been associated with risk factors such as nursery rearing and single housing. However, less is known about the extent of, and risk factors for, abnormal behavior in baboons. The...

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...

Guinea pigs are difficult to oral gavage dose. Previous adverse effects from this dosing method, using rigid catheters, had caused an earlier endpoint to studies and loss of data. We therefore developed a prototype gag...

Little information is available on the response of vervet monkeys to different housing conditions or on the suitability of enrichment devices or methods for vervet monkeys. In this study, the authors evaluated the occurrence of...

The RSPCA/UFAW Rodent Welfare Group holds a one-day meeting every autumn so that its members can discuss current welfare research, exchange views on rodent welfare issues and share experiences of the implementation of the 3Rs...

The welfare of zoo animals depends on a combination of physical, social, dietary and other ecological characteristics of the captive setting. We analysed the influence of the transfer of an adult couple of hamadryas baboons...

Although alopecia may arise from a variety of causes, it is often viewed as an indicator of impaired wellbeing, frequently becoming a focus of regulators or facility managers. However, the extent of alopecia in populations...

Maintaining the psychologic wellbeing of nonhuman primates housed in a laboratory setting is an important aspect in providing the best possible care for these animals. Nonhuman primates kept in captivity can begin to display abnormal...
