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 concentration of glucocorticoid metabolites (GCM) in rabbit faeces has been suggested as a non-invasive indicator of stress. In the present study, GCM concentrations were measured in faeces of fattening rabbits kept in groups of...

Step 1 Gently squeeze the animal about halfway towards you. Hold the animal in place for about 1 to 2 seconds.We use this time to talk to the animal calmly in a gentle voice. When...

The three main divisions of 'marmosetcare.com' aim respectively to promote: an understanding of the range of behaviour in this species, placing this behaviour in the context of its natural habitat and promoting good welfare in...

Physiologic stress has been demonstrated to impair glucose tolerance and insulin action. In the present study, we examined whether glucose tolerance is influenced by restraint stress. Studies were designed using female cynomolgus monkeys (3.2 to...

Training captive nonhuman primates to voluntarily participate in a variety of necessary research and medical procedures is a valuable refinement in the management of captive primates. For the purposes of this talk, training programs require...

Cynomolgus monkeys are acclimated in-house during their 4- to 5-wk quarantine period to pole and collar chair restraint to facilitate safe handling and adequate immobility for study procedures like oral gavage and blood collection. Acclimation...

To enhance the psychological well-being of non-human primates, many biomedical facilities use positivereinforcement training (PRT) techniques to encourage voluntary participation in husbandry and clinical procedures.PRT increases the animal?s control over its environment and desensitizes the...

In a review of current literature on positive reinforcement training, the majority of sources suggest that in order to produce results worthy of the time investment, training sessions must be held 2 to 3 times...

Traditional techniques used to capture New World monkeys, such as net capture, can induce high levels of acute stress detrimental to welfare. Alternatively, training nonhuman animals via operant conditioning to voluntarily participate in husbandry and/or...

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...

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)...

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)...

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...

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...

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)...

When studying pharmacokinetics in rabbits, researchers must often take multiple blood samples from conscious rabbits. Researchers usually collect these samples via the auricular vein, typically through a port or an indwelling catheter. The authors have...

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...

Captive environments encompass various factors that can elevate stress levels and jeopardize the wellbeing of the captive animals. The use of positive reinforcement training (PRT) techniques enables researchers and caretakers to reduce tension directly associated...

PRT is a good way of shaping the behavior of captive animals and doing so can make the animals less stressed to promote their well being. PRT is commonly used by captive animal organizations in...
