Less than three decades have elapsed since the specialty of laboratory animal medicine was first formally recognized. Tremendous progress and maturation has occurred in this short time frame due in large part to the foresight of early pioneers in the field, attention to the moral and ethical use of animals, and the recognition by the biomedical research community of the indispensable role played by the laboratory animal medicine specialist in forging new knowledge in the biomedical sciences. The ability of laboratory animal medicine specialists to properly balance their efforts in collaborative and independent research, clinical services and teaching, offers exciting challenges and opportunities for veterinarians entering the specialty. Undoubtedly, another challenge to the specialty, currently and in the foreseeable future, is the debate over animal rights which began to ferment in the late 1970's, after lying relatively dorment since the 1950's. A growing number of Americans, including some scientists, contend that animals have inherent rights to a full life, free of intentional pain, even when done in legitimate scientific pursuits; some ardent anti-vivisectionists state that the use of animals in experimental research is immoral. The laboratory animal medicine specialist will have to effectively deal with the administrators of institutions using research animals, the attendant federal and state guidelines and laws regulating their use, and defend the use of laboratory animals to a polarized public, while at the same time ensure the humane care and use of animals under their purview. Certainly, the specialty is squarely placed in a hotly debated dilemma, fraught with ethical, moral, medical, philosophical, religious, and political complexities. I believe the specialty has the vision and maturity, and is indeed ready, to successfully meet that challenge - to assuage public concern, implement new federal policy regarding animal care and use, and maintain the excellent progress in laboratory animal medicine realized in the last 75 years.
