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 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
[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.

preparation example Construction

[0025] A preparation method of Gynostemma pentaphyllum extract feed additive, the specific steps are as follows:

[0026] Respectively shorten the whole plant of Gynostemma pentaphyllum, wash and sort out;

[0027] Put the raw materials into an alcohol extraction tank, add 3 to 6 times the weight of 60% to 95% ethanol, boil for 3 to 6 hours, the vapor pressure is 0.4 to 0.7 MPa, and the ethanol is refluxed;

[0028] Filtrating after the first alcohol extraction to obtain the first filtrate and the first filter residue respectively; wherein, the first filtrate recovers ethanol through a decompression concentration tank until the recovered ethanol is less than 60% and stops recovery, and the first filtrate continues to concentrate to obtain a concentrate;

[0029] 60%~95% ethanol of 3~6 times of weight is added to the first filter residue for the second time, boiled for 3~6 hours, the steam pressure is 0.4~0.7MPa, the ethanol is refluxed, until the recovered ethanol<60%, stop th...

Abstract

The invention discloses a fiveleaf gynostemma herb extract feed additive and a preparation method thereof, and a preparation is formed by performing multiple extraction on roots and stems of fiveleaf gynostemma herbs, and then uniformly mixing with a carrier. The preparation method comprises the following steps: step 1) performing preliminary extraction on the roots and the stems of the fiveleaf gynostemma herbs; and step 2) performing secondary circulating extraction on remains after the extraction in the step 1), performing spray-drying treatment on the obtained liquid extract, and the uniformly mixing with the carrier for forming the fiveleaf gynostemma herb extract feed additive. The fiveleaf gynostemma herb extract feed additive has the functions of benefiting qi for tranquillization, strengthening body resistance, having antibacterial and anti-inflammation effects and enhancing animal immunity.

Description

technical field [0001] The invention relates to a Gynostemma pentaphyllum extract feed additive and a preparation method thereof, which have the functions of nourishing qi and calming the nerves, strengthening the body, strengthening the body, antibacterial and anti-inflammatory, and enhancing animal immunity. It belongs to the technical field of natural plant additives. 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 ...
