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. 

Authors evaluated plasma corticosteroid concentrations in male rhesus macaques who were trained to enter voluntarily a restraining apparatus and permitted venipuncture without showing signs of stress. Basal cortisol values were 30% lower than previously reported...

An abnormal but apparently successful sexual posture was observed in an adult male rhesus monkey in which the subject bit its hands and leg in the process of dismounting. This behavior followed each of several...

Heart rate of single-housed subjects increased coincident with human activity in the animal room, reaching peaks during feeding and cleaning.Heart beats/min measured via telemetry:Basal [before entering room] 138 +/- 25Person enters room: 150 +/- 25Person...

Results and studies to date suggest that the presence of companions can reduce both the magnitude and frequency of reaction to aversive or stressful stimuli .

In 3 separate experiments, 110 male albino Sprague-Dawley rats were given the opportunity to approach either a tethered stimulus rat or a responsive human hand. Ss were very attracted to the other rats but, when...

Hairball formation in humans occurs most frequently in emotionally disturbed females below the age of 30. It is possible that individual caging of rabbits over long periods of time could affect their psychological health and...

Audiogenic seizures, changes in parameters of the stress syndrome, and disturbance of acoustic communication in rodents are discussed as possible harmful effects of noise and evaluated in regard to standards published in Germany for man...

The effects of human social contact on the electrocardiogram (EKG) and general behavior of 2 horses were explored. Petting elicited a slowing of heart rate, while a person entering and exiting elicited transient, but often...

The recommendations and guidelines suggested here should be considered as tentative. Specific procedures are subject to modification in accordance with individual situations, colony size, and personal preference.A serious handicap to the development of adequate care...

What we have demonstrated is that the introduction of rhesus monkeys [both sexes, different ages, different rearing histories/personalities] to an established rhesus monkey social unit can be a potent stimulus for eliciting aggression. ... Rhesus...

The effects of handling and novel environment on cortisol, prolactin and growth hormone were assessed and different control mechanisms discussed. Handling and novelty of the environment are powerful stimuli to activate the pituitary-adrenal axis.

Primates can injure personnel severely if adequate restraint is not used. The risk of herpesvirus B infection and other zoonoses transmitted by bite or scratch is minimized by appropriate restraint which may be physical or...

Rhesus macaques sleep in trees sitting on branches, mostly in clusters of 2-3 monkeys huddled together.

He groomed the infant very carefully for a little over five minutes. The infant clung to Mellow's ventrum, climbed on his back, shoulders, and head, and leaned over backwards while holding onto his ears. Immediately...

Forceful restraint method for electrocardiogram recording is described and demonstrated. Though ECGs have been recorded with minimal stress to the animals heart rate tended to rise because of the stress of the animal being removed...
