Description

Technical field [0001] The invention relates to a method for preparing a feed additive, in particular to a method for preparing a wolfberry extract feed additive for animals, and belongs to the technical field of natural plant feed additives. Background technique [0002] With the continuous development of the aquaculture industry in our country, diseases of various farmed animals have become a prominent problem restricting the development of this industry. In terms of common infectious diseases alone, their types are very complex, including bacterial diseases, parasitic diseases, viral diseases, etc. At the same time, various types of diseases transmitted through the respiratory and digestive tracts are also deeply troubled. Breeders everywhere, respiratory and digestive tract diseases and digestive tract diseases are increasingly threatening the pig industry in our country, and it has reached the point where it is indispensable. At present, the breeding industry mainly uses me...

Problems solved by technology

[0003] Veterinary drug products are abused in the breeding process, and human medicines are used in the breeding industry, which poses hidden dangers to human health

For the problem of adding a large amount of antibiotics and ripening hormones to the feed, although the drug prevention and control technology is relatively effective, it is also the main prevention method currently used, but its side effects are also very prominent, and the emergence and expansion of drug resistance must have no residual effects. pollution to the environment, etc.

Now the use of chemical drugs, especially antibiotics and hormones, has been very strictly restricted

[0004] Although Chinese herbal medicines have entered the ranks of feed additives at present, their workmanship is rough, most of them are directly crushed, their active ingredients are not clear, their absorption is slow, and their active ingredients are not easy to absorb.
