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. 

There are many benefits of positive reinforcement training (PRT). PRT reduces stress for subjects and as such is a significant refinement to animal care practices. However, training can be time intensive, and not all animals...

Positive reinforcement training (PRT) methods can be applied to gain the voluntary cooperation of laboratory primates with the collection of biological samples. Information will be provided on training techniques used and the amount of training...

Traditional procedures for training nonhuman primates to be restrained in chairs typically involve very little use of positive reinforcement. In this talk, we detail a refined chair training procedure which uses a mix of positive...

Using behavioral data to predict pair stability would be helpful for improving management of pairs and prevention of injury. Differences in reactions to presumed laboratory stressors, such as location moves, may provide information about pair...

In the last decade several surveys of primate care and training programs highlight a common theme; despite scientific evidence that animal training can be effective in reducing stress, increasing efficiency and improving veterinary care, animal...

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...

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...

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...

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...

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 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...

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...

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...

Positive reinforcement training (PRT) efficiency was examined as a function of training frequency in 33 pair- or triple-housed female rhesus macaques. The animals were trained three times a week, once a day or twice a...

Operant conditioning using positive reinforcement techniques has been used extensively in the management of nonhuman primates in both zoological and laboratory settings. This research project was intended to test the usefulness of counter-conditioning techniques in...

At the California National Primate Research Center, one key to long-term success of macaque breeding colonies is to develop effective infant-rearing strategies that minimize the emergence of behavioral pathologies, which can be one indicator of...
