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 report sets out how to provide: optimal enclosure characteristicsand size; social housing; solid flooring and substrate; raised areas; refuges; gnawing objects and dietary enrichment; positive interaction with humans; toys and objects to manipulate; for...

Adriane and Kris just trained eight rhesus monkeys to present their arms in the blood sleeve for blood samples, and it took, on average ... 8 months ... 160 minutes spread out into 40 sessions.

The application of positive reinforcement training (PRT) has increased in zoological, laboratory, and research settings in recent years, however there is little literature pertaining to the development and implementation of such programs. Over the past...

While strictly using positive reinforcement and applying patient gentle-firmness, most macaques can be trained to cooperate during the pole-attachment-chairing procedure. Some cannot be trained, because they have problems overcoming their often-legitimate mistrust of humans.

Positive reinforcement training is an important element of behavioral management programs for nonhuman primates. However, more empirical information is needed to determine whether animals identified for intervention will engage in such training, affecting the amount...

This article provides details to consider when preparing to use animals in biomedical research. The stress of transport and receipt of animals into a new environment mandate the need for a period of stabilization and...

Preparation of domestically bred animals for research usually involves some combination of social separation, relocation, resocialization, alterations in physical space, photoperiod, and diet, as well as exposure to novel environments. The research literature that has...

Non-human primates (NHPs) are utilized frequently in biomedical research and can be difficult and sometimes dangerous to handle. Because of this, restraint is sometimes necessary for data collection. Restraint chair training is generally a straightforward...

This article provides a brief historical background of the events and circumstances that led to the 1985 Animal Welfare Act (AWA) amendments. It describes the development of the regulations promulgated by the US Department of...

Experiences with the pole-and-collar training training are shared. Yes, most monkeys can be trained but some cannot, or let's say they should not be trained because their personality -- which is presumably conditioned through negative...

The question was asked: "I am currently pole-and-collar training one of our adult pair-housed rhesus females and hope to get her to graduate to the chair in the next few weeks. Winnie remains sitting when...

12 adult pair-housed female, 5 adult single-housed male and 10 adult pair-housed male rhesus macaques, and 6 adult pair-housed female stump-tailed macaques were trained to cooperate during in-homecage blood collection. The total number of training...

A major focus of this paper is an examination of the complementary role that behavioral management strategies play in the establishment and enhancement of well-defined nonhuman primate research resources. .... Additionally, I will discuss the...

Training program for voluntary ejaculation is described. In May 1998 we began the training program with Xebo. At the time of this writing (March 1999) Xebo understands ten different orders. ... So we hope that...

The use of "pre-invasive" implantable radio telemetry has revolutionized the collection of physiological data under stress-free conditions. It is now possible to measure accurately 'normal' baseline data of haemodynamic and electrical parameters in conscious and...

Twenty-six reports provide detailed information of how primates can be trained to voluntarily cooperate - rather than resist - during blood collection, injection, topical drug application, blood pressure measurement, urine collection, and capture.

Practical recommendations to address five basic characteristics of Old World primates in the laboratory setting: a) social disposition, b) semi-arboreal lifestyle, c) complex living environment, d) intelligence, e) sensitivity to distress.

A monkey housed in an empty cage, however, is literally a behavioral cripple because s/he is chronically deprived of appropriate stimuli for the expression of species-typical behavior patterns. It is difficult to know objectively if...

Because of the influence in behaviour, we can say that visitors are a kind of environmental enrichment. .... Sometimes visitors have a negative effect (increase of aggressive behaviour, begging for food) and in some cases...

Training protocol is described. These findings lead to the conclusion that training nonhuman primates to cooperate during venipuncture in their familiar home environment offers a methodological refinement by eliminating significant cortisol responses.

Published information provides scientific evidence that traditional, involuntary restraint techniques of research non-human primates are intrinsically a source of distress resulting from fear. It has been documented that common methods of enforced restraint result in...

With some professional expertise and goodwill, there should be no real need to resort to forceful restraint when doing research with nonhuman primates.

This study demonstrates that only a minimal time investment was needed to train a large troop of laboratory non-human primates to co-operate in the catching procedure. A group of 45 rhesus macaques (Macaca mulatta) was...

New techniques were developed to avoid the manual transfer - and the associated health hazard - of caged macaques during handling procedures.
