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. 

Research has shown animals are sensitive to environment changes and novel caretakers. The behavioral response to environmental change is often expressed as a decrease in willingness to comply or perform learned tasks. We assessed the...

Animal training programs are used at many animal facilities to refine human-animal interactions. While there is a strong focus on positive reinforcement training (PRT) over negative reinforcement training (NRT) or punishment, animals vary in responsiveness...

Through the use of operant conditioning methods, that is, clicker training, it is possible to train nonhuman primates to check their automatic watering system. Primate species not indicated. We will detail a training study.

We have successfully trained with a laser pointer at least one cyno in each pair/group to target to their lixits. Currently this stands at about 35 cages housing a total of 63 animals. We no...

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...

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...

Cognitive abilities likely evolved in response to specific environmental and social challenges and are therefore expected to be specialized for the life history of each species. Specialized cognitive abilities may be most readily engaged under...

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...

For groups of pigs to cope adequately with their housing conditions they need sufficient static space (occupied by the body of the pig), activity space (for movement between different functional areas and behaviours relating to...

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...

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...

Routine laboratory procedures can be stressful for laboratory animals. We wanted to determine whether human handling of adult rabbits could induce a degree of habituation, reducing stress and facilitating research-related manipulation. To this end, adult...

Recently a researcher approached our large animal facility manager about housing 19, 2-mo-old piglets and assisting with data collection. Part of the protocol required that the piglets be fed an individually measured high-sugar/high-fat diet over...

Animal care for nonhuman primates (NHPs) in biomedical facilities has undergone major changes in the past few decades. Today, most primate facilities have dedicated and highly trained animal care technicians who go to great efforts...

To quantify the combined effect of housing conditions and environmental enrichment on the behaviour and performance of pigs, a meta-analysis was performed using information from 45 experiments in 42 published manuscripts. Multiple regression models were...

Clicker training minipigs provides a significant improvement in the dermal dosing procedures.

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...
