Background

Animal experiments refer to scientific research conducted in laboratories using animals in order to gain new knowledge about biology, medicine, etc., or to solve specific problems. Animal experiments must be performed by or under the direction of trained, academic or professional skilled personnel. The final aim of the scientific development of experimental animals is to develop into human beings by researching the life phenomena of the animals, explore the mystery of human life, control the diseases and aging of the human beings and prolong the life of the human beings. With the rapid development of medical science and bioscience, it is recognized that the public hazard problem not only becomes a serious social problem of food, population, the elderly, etc., but also relates to the survival problem of animals living on the earth, such as industrial public hazard, food public hazard, drug toxicity, etc., which directly affect human health, and the research on the problems finally inevitably requires the elucidation and solution of animal experiments (including the development of animal disease models, etc.). Therefore, the importance of experimental animal science, particularly experimental animals, is more and more recognized and has been considered as the pillar for human beings to pursue happy life, so experimental animal science is also called life science; therefore, advanced countries pay high attention to the development of experimental animal science, the input economic materials and technical force can be almost compatible with the development of atomic energy science, and the important significance of the development can be thought of. And are not presently replaceable by other means.
