Method for preparing solidago Canadensis extract feed additive

Abstract

The invention discloses a method for preparing a solidago Canadensis extract feed additive. The method comprises the following steps of: collecting a complete solidago Canadensis and clearing solidago Canadensis; putting the raw materials into an ethanol extracting tank; adding ethanol; boiling; performing ethanol reflux; filtering after extracting ethanol for the first time to obtain filtrate and filter residue respectively; allowing the filtrate to pass through a vacuum pressure reduction concentration tank to recover the ethanol; concentrating the concentrated liquid continuously to obtain concentrated solution; adding ethanol into the filter residue for the second time; boiling; performing ethanol reflux; filtering to obtain first filtrate and filter residue; adding water into the filter residue; boiling; filtering to obtain second filtrate and filter residue respectively; discarding the filter residue; mixing and concentrating the concentrated solution, the first filtrate and the second filtrate to obtain solidago Canadensis extractum; putting the extractum into a container to refrigerate and store; and drying the extractum to obtain the solidago Canadensis extract dried powder. The solidago Canadensis extract feed additive avoids medicament residue, is safe and harmless, clears heat and relieves toxin, and eliminates swelling and relieves pain. The solidago Canadensis extract feed additive has the effects of sterilizing, diminishing inflammation, easing pain, relieving cough and eliminating phlegm.

Description

technical field [0001] The invention relates to a preparation method of a feed additive, in particular to a preparation method of a solidago canadensis extract feed additive for animals. Background technique [0002] Solidago Canada taxonomically belongs to the Asteraceae family, Solidago L.. There are about 125 species of this genus in the world, mainly distributed in North America, and a few are distributed in Europe and Asia; there are 4 species in China, both in the north and the south; there are 2 species in Zhejiang, that is, Canada Goldenrop (S. canadensis L., English Canada Goldenrop ) and Solidago (S.decurrens Lour., English Common Goldenrop). Because the two are different species and cannot be confused, it is inaccurate to call "Solidago canadensis" "Solidago". Belongs to gymnosperms. [0003] Solidago canadensis, also known as yellow warbler and goldenrod. This kind of flower is bright in color and is imported from Canada. It is called "Happy Grass" in the flo...

Problems solved by technology

[0006] 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 the main prevention method currently used, its side effects are also very prominent, such as the generation and expansion of drug resistance, no residual effects of various types, pollution to the environment, etc.

The use of chemical drugs has also been very strictly restricted

[0007] Although Chinese herbal medicines have entered the ranks of feed additives at present, their workmanship is rough and most of them are directly crushed.

Its active ingredients are not clear, the dosage is large, the absorption is slow, the active ingredients are not easy to absorb, and the onset of action is slow. The Chinese herbal medicine extract just makes up for the above shortcomings, and has the characteristics of less dosage, clear target organs, and fast action.
