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. 

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...

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...

At the Oregon National Primate Research Center, we train animals to enter transfer boxes using positive reinforcement training (PRT), a type of training in which the trainer reinforces desired behaviors (such asentering the transfer box)...

The quantification of behaviours linked to anxiety or stress provides a powerful means to address applied questions related to the well-being of captive animals. This study explored correlates of two such behaviours: self-directed (SDB) and...

Studies have shown chimpanzees can learn to perform tasks by watching live or videotaped demonstrators. The present study assessed whether female chimpanzees exposed to a videotaped demonstrator would learn a husbandry-related task, urinating into a...

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...

The quality of human-animal interactions can be an indicator of well-being in laboratory primates and increased anxiety-related behavior, such as aggression, may compromise an animal’s ability to provide research outcomes reflective of normal function. The...

The pole and collar method enables safe transfer of a monkey from their home environment to a restraint chair without sedation. The ability to conduct procedures with a conscious and cooperative subject is cost effective...

Positive reinforcement training relies on identifying an effective reinforcing consequence, often food, to be presented contingent on the performance of the desired behavior. Prior to training sessions, we used a multiple stimulus without replacement (MSWO)...

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...

Chimp Haven has retired 153 chimpanzees, the majority from biomedical research, and abnormal behavior patterns have been reported. Abnormal behaviors are well described in chimpanzees and usually related to early rearing environment, social isolation and...

Operant training of animals is a widely accepted practice for training or conditioning animals to cooperate with technical procedures or perform certain tasks in a laboratory setting. This type of training has been proven to...

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...

Operant training of animals is a widely accepted practice to train or condition animals to cooperate with technical procedures or perform certain tasks in a laboratory setting. This type of training has been proven to...

While access to a foraging log had no curative effect on serious self-injurious biting of a single-caged subadult male baboon, transferring the animal to an outdoor section with compatible females in adjacent cages (allowing grooming...

Stereotypic behavior is a pervasive problem for captive monkeys and other animals. Once this behavior pattern has started, it can be difficult to alleviate. We tested whether or not using positive reinforcement training (PRT) can...

The physiologic and anatomic structure of rabbits can cause high mortality rates in rabbit oral gavage. Rabbits are capable of a wide variety of jaw movement due to 3 jaw-closing muscle groups (masseter, temporalis, pterygoid)...

Restricted experience in early life is known to contribute to long-lasting predispositions to fear and anxiety in mammals. It is commonplace for young domestic dogs not to experience many features of the environment in which...

COST Action B-24 established four working groups to research and discuss issues relevant to laboratory animal science. These included the housing of animals, environmental needs, refinement of procedures, genetically modified animals, and cost-benefit analysis. Based...

This study examined the effectiveness of an anxiolytic drug, buspirone, in rhesus macaques with a history of self-injurious behavior. ... However, self-biting was more prevalent during periods of high activity. Treatment with buspirone was not...

Investigators using companion animals for research are often faced with the dilemma of what to do with healthy animals when a study is complete. At our institution, it is not uncommon for investigators to submit...

Early descriptions of floating limb behaviors in monkeys were associated with isolation rearing, a practice that ended more than two decades ago. The present authors named various forms of behaviors in which a leg is...

Positive reinforcement training is one component of behavioural management employed to improve psychological well-being. There has been regulatory promotion to compensate for restricted social housing in part by providing human interaction to singly caged primates...

It is now more than 20 years since both Council of Europe Convention ETS123 and EU Directive 86/609/EEC were introduced, to promote the implementation of the Three Rs in animal experimentation and to provide guidance...
