ILAR promotes high-quality, humane care of laboratory animals and the appropriate use of laboratory animals and alternatives in research, testing, and education. ILAR serves as an advisor to the federal government, the biomedical research community, and the public. IV

The National Academy of Sciences is a private, nonprofit, self-perpetuating society of distinguished scholars engaged in scientific and engineering research, dedicated to the further- ance of science and technology and to their use for the general welfare. Upon the authority of the charter granted to it by the Congress in 1863, the Academy has a mandate that requires it to advise the federal government on scientific and technical matters. Dr. Bruce M. Alberts is president of the National Academy of Sciences. The National Academy of Engineering was established in 1964, under the charter of the National Academy of Sciences, as a parallel organization of outstanding engineers. It is autonomous in its administration and in the selection of its members, sharing with the National Academy of Sciences the responsibility for advising the federal government. The National Academy of Engineering also sponsors engineering programs aimed at meeting national needs, encourages education and research, and recognizes the superior achievements of engineers. Dr. Harold Liebowitz is president of the National Academy of Engineering. The Institute of Medicine was established in 1970 by the National Academy of Sciences to secure the services of eminent members of appropriate professions in the examination of policy matters pertaining to the health of the public. The Institute acts under the responsibility given to the National Academv of Sciences bY its congressional charter to be an adviser to the O federal government and upon its own initiative to identify issues- of medical care, research, and education. Dr. Kenneth I. Shine is president of the Institute of Medicine. The National Research Council was established by the National Academy of Sciences in 1916 to associate the broad community of science and technology with the Academy's pur- poses of furthering knowledge and advising the federal government. Functioning in accor- dance with general policies determined by the Academy, the Council has become the principal operating agency of both the National Academy of Sciences and National Academy of Engi- neering in the conduct of their services to the government, the public, and the scientific and engineering communities. The Council is administered jointly by both Academies and the Institute of Medicine. Dr. Bruce M. Alberts and Dr. Harold Liebowitz are chairman and vice- chairman, respectively, of the National Research Council. Vl
Preface Biomedical and behavioral research, product testing, and many aspects of science education rely heavily on the use of animals. Quality care of these animals is essential, not only for the animals' welfare, but also for obtaining valid data. Environmental and biologic factors can influence experimental results by exerting subtle influences on an animal's physi- ologic characteristics, behavior, or both. Although there is a tendency to feel more concern for species to which humans develop an attachment (e.g., dogs and cats) and species that are biologically "closer" to humans (nonhu- man primates), the same attention to environmental control for and good care of every laboratory species is necessary to ensure the high quality of both science and ethical practice. Rodents are, by far, the largest group of animals used in research and testing. In 1986, the Office of Technology Assessment estimated that 17-22 million animals were being used each year in the United States, of which about 13.2-16.2 million were rodents (Alternatives to Animal Use in Re- search, Testing, and Education; Pub. No. OTA-BA-273; U.S. Congress Of- fice of Technology Assessment; Washington, D.C.; 1986~. In the 15 years since the last Institute of Laboratory Animal Resources report on the gen- eral management of rodents was published, important advances in biomedi- cal research and increased public awareness have created a new environ- ment for animal research. Modern technology- such as insertion of functional genes from other species into mice or rats, elimination of a single selected . . V11
. . . V111 PREFACE gene or function in mice, and the re-creation of elements of the human immune system in mice has greatly expanded the usefulness of rodents in drug development and as models of human diseases. The technologic re- quirements of such advanced systems have led to improved understanding and implementation of environmental requirements for the care and use of rodents in research. The intent of this report is to provide current information to laboratory animal scientists (including both animal-care technicians and veterinarians), investigators, research technicians, and administrators on general elements of rodent care and use that should be considered both for optimal design and conduct of research and to meet current standards of care and use. We emphasize that this report provides guidelines and should not be used as a substitute for good professional judgment, which is essential in the applica- tion of the guidelines. Where possible, we refer to other documents that provide more detail on specific aspects of rodent care and use. Bonnie J. Mills, Chairman Committee on Rodents
