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. 

Juvenile male pigs were sedated for castration. Eight five-month old boars were sedated twice (two weeks apart) with a combination of detomidine (0.1 mg/kg), midazolam (0.2 mg/kg) and either butorphanol (0.2 mg/kg) (Group MDB, n...

Lack of environmental enrichment and high stocking densities in growing-finishing pigs can lead to adverse social behaviors directed to pen mates, resulting in skin lesions, lameness, and tail biting. The objective of the study was...

Oral sucrose was evaluated for its ability to reduce pain following castration. Piglets (n = 126) were assigned to one of the five treatments: (1) castrated and given 3 mL of water (C); (2) castrated...

Understanding the factors associated with the long-term stress levels of captive animals is important from the view of animal welfare. In this study, we investigated the effects of relocation in addition to individual and environmental...

The debate on the use of chimpanzees (Pan troglodytes) in biomedical research has been ongoing for several years now. In 2012, the decision was made to retire a large number of laboratory chimpanzees in the...

Experimental procedures, such as dosing, weighing, and physical exams are usual parameters included in nonclinical safety and efficacy studies using laboratory animals. Many of these procedures are often associated with discomfort for the animals and...

Chimpanzees (Pan troglodytes) have served in biomedical and behavioral research since the early 1900s and captive breeding programs to supply chimpanzees have been common since the 1960’s. The captive research population reached a peak of...

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...

Swine are an important model in many areas of biomedical research. These animals have been used predominantly as preclinical models involving surgical and interventional protocols. The systems most commonly studied include cardiovascular, integumentary, digestive, and...

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...

The chimpanzee is the only representative of the Great Apes that is extensively involved in biomedical research in primate laboratories. These apes are used as animal models in a variety of studies, including research on...

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.

The present article represents a consensus view of the appropriate utilization of chimpanzees in AIDS research arrived at as a result of a meeting of a group of scientists involved in AIDS research with chimpanzees...

New World monkeys represent an important but often poorly understood research resource. The relatively small size and low zoonotic risk of these animals make them appealing as research subjects in a number of areas. However...
