With the improvement of people's living standards and the enhancement of health care awareness, the demand for animal food has changed from quantity to quality. The production of green animal food caters to people's needs. Natural Chinese herbal medicine, with its unique advantages of no toxic side effects, no harmful residues, no stress reaction, no drug resistance and no environmental pollution, has become a beneficial additive in the production of green animal food, and has become the focus and hot spot of animal husbandry workers. China's rich Chinese herbal medicine resources and unique and complete theoretical system of Chinese medicine have laid a solid foundation for the development of Chinese herbal medicine. However, at present, most drugs or additives used to prevent and control livestock diseases, promote growth and increase production are chemical preparations. Long-term and large-scale use of chemicals will not only lead to adverse consequences such as drug resistance, stress reaction and poisoning. Moreover, the harmful components left in livestock products such as meat, eggs and milk will directly endanger human health. Modern medical research shows that; Antibiotic residues in animal-derived foods may lead to the mutation of human DNA structure, thus causing serious consequences such as "disability", "teratogenesis" and "carcinogenesis". At present, the application research of natural Chinese herbal medicine in animal husbandry is still in its infancy, and its development level is low, which is far from meeting the rapid development of intensive animal husbandry.

Chinese herbal medicine, as a natural organic substance, adopts automatic, botanical, mineral and its products to maintain the natural state and biological activity of various component structures. These substances were originally indispensable for the composition of the earth's organisms and the maintenance of ecological balance, and at the same time, they were the most easily accepted exogenous essence substances that were beneficial and harmless to people and animals after long-term practice screening, and then the unfavorable factors to the body were removed by natural processing methods (water, fire, etc.). ) was founded by China, thus maintaining its pure naturalness. Natural Chinese herbal medicine is a complex organism with dozens or hundreds of components. The compound ingredients composed of a variety of Chinese herbal medicines are more complicated. When many ingredients act on animals together, it will often produce the combined effect of many ingredients, that is, the comprehensiveness and integrity of drug efficacy. The complex composition and structure of natural Chinese herbal medicines determine their unique characteristics, namely naturalness, pluripotency, no toxic side effects and no drug resistance. Pluripotency mainly includes nutrition, immune enhancement, hormone-like effect, vitamin-like effect, anti-stress and "adaptogen"-like effect, two-way regulation, anti-microbial effect and compound effect. Natural Chinese herbal medicines can enhance the immune function, strengthen the body resistance, eliminate pathogens, stabilize yin and yang, regulate deficiency and excess, and comprehensively regulate the whole body, so that the body can achieve the best functional state. Moreover, some beneficial factors are derived and retained in animal food, which can also improve the sensory quality, medicinal value and health care level of animal food and strengthen animal functional food.

Wide resources and low cost. China has a vast territory, rich in Chinese herbal medicine resources, easy to plant and harvest, and easy to use.

There is no drug residue and no pollution in animals. Chinese herbal medicine is a natural substance, which maintains the naturalness and biological activity of various components. Its components are easy to be absorbed and utilized, and those that cannot be absorbed can be excreted smoothly and decomposed by bacteria in vitro without polluting the water environment. But the general chemical components will accumulate in animals or remain in water for a long time.

There are few or no toxic and side effects, and animals do not produce drug resistance. Toxic Chinese herbal medicines will be reduced or disappeared after proper processing; Through the compatibility of prescriptions and the interaction between traditional Chinese medicines, the curative effect of disease prevention and treatment is improved, and the toxic and side effects are weakened or reduced. So far, medical research has never found the problem of drug resistance of Chinese herbal medicines.
