Laboratory animals are essential for the successful execution of many health programmes. A wide variety of animal models is used in the worldwide efforts to improve the control of various diseases, and in the basic research needed to improve health care. Biomedical programmes require specially-bred animals reared under controlled conditions, with close attention given to such factors as physical environment, nutrition, microbiological status, and genetic background. The need for a regular supply of appropriate animals has led to the development of a field of study known as laboratory animal science, and a speciality within veterinary medicine known as laboratory animal medicine. The importance of laboratory animals is recognized by the World Health Organization, which, in cooperation with other organizations, provides training, technical information, and consultative support in this field. |
