The purpose of the development of experimental animal science is to study the life phenomena of animals themselves and then apply them to humans, explore the mysteries of human life, control human diseases and aging, and extend human lifespan. With the rapid development of medical and biological sciences, it has been recognized that public nuisances have not only become major social issues such as food, population, and the elderly, but also involve the survival of animals living on the earth, such as industrial nuisances, food nuisances, and drug toxicity, all of which directly affect human health. Research on these issues, It is inevitable to clarify the solution through animal experiments (including the development of animal disease models, etc.). Therefore, the importance of experimental animal science, especially experimental animals, is increasingly recognized by people. It has been regarded as the pillar for human beings to pursue a happy life, and thus experimental animal science is also called life science. For this reason, advanced countries have attached great importance to the development of experimental animal science. The economic materials and technical forces they have invested are almost on par with the development of atomic energy science. The significance of this can be imagined. And it cannot be replaced by other means at present.

Experimental animal science has become an inseparable part of modern science and technology and has formed an independent and comprehensive basic science category. The significance of this science lies in that, on the one hand, as an important means of scientific research, it directly affects the establishment and level of research results in many fields. On the other hand, as a science, its improvement and development will bring the research of many field topics to new heights. Therefore, the significance of experimental animal science and technology can be summarized in the following three sentences: It is an important component of modern science and technology, the foundation and condition of life science, and an important indicator to measure the scientific research level of a country or a research institution.

Experimental animal science was formed along with biomedical science through a long process of animal experiments. However, the rapid development of experimental animal science has made the research value of experimental animals no longer limited to the field of biological science, but is widely and closely linked to scientific experimental research in many fields, becoming an indispensable condition for ensuring modern scientific experimental research. In scientific research in many fields, experimental animals play a very important role in safety tests, effect tests and standard tests.
