学科导论（An introduction to the subject）Research on the prevention and treatment of veterinary medicine is the science of animal diseases. With livestock, animal (such as dogs and cats, etc.), economic wild animal, animal, ornamental animal, economic insects (such as bees, silkworms and etc.)

The health and disease prevention fish are veterinary medicine category. With the development of medical and health services and veterinary medicine category has been broadened to involve zoonotic diseases, public health, environmental protection, disease model, animal, food production, pharmaceutical industry and other fields, and has formed many new interdisciplinary, has played an increasingly important role in agricultural production, biology and human medicine the development of.

The modern veterinary task is not only to develop the protection of animal husbandry, but also reduce zoonotic diseases of Veterinary Science

Harm, improve animal food (meat, eggs, milk and aquatic products) the hygienic quality and improve the environment and health, for human health services. Veterinary clinical diagnosis and treatment work most of the value of expensive individual livestock or livestock, and some animal, with ornamental animal as the main object, generally focuses on prevention and control of livestock group. The rapid development of factory intensive poultry and pig industry, increase of veterinary feeding site selection, design, livestock feed additive preparation, immunization program

formulation and implementation of environmental health management, disease diagnosis and monitoring the immune level of responsibility, in order to improve the health level of livestock and disease prevention group, including infectious disease, parasitic disease, poisoning disease and nutritional and metabolic diseases, the disease has been found in hundreds of. The damage was most intense but many infectious diseases have been eliminated. As of 1986, compared with the developed countries in animal husbandry livestock infectious disease has been eliminated for Denmark in 18, the United States and Japan 13, UK 10, Australia 7, the Soviet Union and the Federal Republic of Germany 6. Over the past year China caused hundreds of thousands or even millions of cattle died of rinderpest, had been wiped out in 1956. But at the same time, many new diseases have occurred, harmful: viral infectious diseases (such as swine vesicular disease), poisoning disease seriously polluted with pesticides, fertilizers and other industrial waste produced, and nutritional and metabolic diseases. Some of them have no effective prevention methods, some (such as metabolic diseases and nutritional deficiency) and one-sided pursuit of high yielding. This is a new topic of veterinary workers. For the prevention of nutritional and metabolic disease early, now veterinary work should not only observe whether herd clinical symptoms, but also to determine whether the production index and metabolism expected whether in equilibrium under certain conditions, such as through blood chemical analysis of the metabolic profile test of high yield cows, with recessive nutritional and metabolic prediction disease or subclinical cases.

The theoretical basis of veterinary science and medicine are
