Description

technical field [0001] The invention relates to a preparation method of a feed additive, in particular to a preparation method of an andrographis paniculata extract feed additive for animals. The invention is applied in the field of preparation of additives for animal feed. Background technique [0002] With the continuous development of my country's breeding industry, diseases of various farmed animals have become a prominent problem restricting the development of this industry. As far as the common infectious diseases are concerned, the types are very complex, including bacterial diseases, parasitic diseases, viral diseases and so on. At present, in the breeding industry, such diseases are mainly prevented and controlled by vaccination and drug prevention and control. [0003] At present, the common vaccine prevention and control is only aimed at the specific immune system of the animal body, and is not very specific to other types of pathogens. Moreover, a vaccine can o...

AI Technical Summary

Problems solved by technology

[0003] At present, the common vaccine prevention and control is only aimed at the specific immune system of the animal body, and is not very specific to other types of pathogens. Moreover, a vaccine can only prevent one disease, and it takes more than a week for antibody production. Its use requires strict use management measures, so the role of vaccine prevention and control in production is also extremely limited

Although there are a large number of vaccine products on the market at present, the good and the bad are intermingled, and the improper use in the process of use makes the effect of vaccine prevention has been poor.

Although drug prevention and control technology is relatively effective and is currently the main prevention method, its side effects are also very prominent, such as the generation and expansion of drug resistance, the residual effects of multiple drugs, and environmental pollution, etc.

The use of chemical drugs has also been very strictly restricted

[0004] Although Chinese herbal medicines have entered the ranks of feed additives at present, their workmanship is rough and most of them are directly crushed.
