Embodiment 1

[0052] Example 1: The crude extracts of dandelion and astragalus were biotransformed to produce feed additives by different microorganisms.

[0053] Take Aspergillus niger and Bacillus subtilis and store them at 4°C;

[0054] Step 1: Biotransformation of crude extract of dandelion by Aspergillus niger

[0055] This example is mainly to increase the content of total flavonoids in active ingredients of dandelion, so as to improve the immunity of livestock and poultry, and promote the growth of animals.

[0056] (1) Preparation of Aspergillus niger seeds and fermentation medium

[0057] Inoculate Aspergillus niger in the seed expansion medium, put it in a constant temperature incubator at 35°C-40°C and cultivate it for 2-3 days, then insert the seed optimized fermentation medium and place it in a constant temperature shaking table at 35°C-40°C Cultivate in the box for 2-3 days, and fill each 300ml triangular bottle with 50ml liquid medium to obtain the cultured Bacillus subtili...

Embodiment 2

[0084] Example 2: Production of feed additives by solid fermentation of dandelion and astragalus by different microorganisms

[0085] Step 1: Fermentation of dandelion solid by Aspergillus niger

[0086] This example is mainly to increase the content of total flavonoids in active ingredients of dandelion, so as to improve the immunity of livestock and poultry, and promote the growth of animals.

[0087] (1) the preparation of Aspergillus niger seed and seed optimization fermentation medium is identical with embodiment 1;

[0088] (2) Preparation of Dandelion

[0089] Pulverize the dandelion to 80 orders with an ultrafine pulverizer, then soak it with 35% water, and set aside.

[0090] (3) Fermentation of dandelion solids by Aspergillus niger

[0091] Mix 20% of Aspergillus niger agent with 2:1:1 ratio of aminoacetic acid, urea, 20% of inorganic salts and 60% of dandelion evenly, put it into a ventilated tank, ferment for 5 days at 35-40°C, extract with water, alcohol Sink,...

Abstract

The invention relates to a preparation method of a feedstuff additive that biologically transformed from natural bioactive components, and is characterized in preparing feedstuff additive from natural vegetation fermenting technique. The preparation method is that Aspergillus niger and Bacillus subtilis are respectively cultivated, a powder and product can be acquired by fermenting liquid or solid Dandelion with Aspergillus niger or Bacillus subtilis, or by fermenting liquid or solid milk veteh with Bacillus subtilis, and the three dry powders are mixed, sieved, thus acquiring a mixed dry powder end product, i.e., natural vegetation drug feedstuff additive. The invention has the advantages that can improve total contents of flavone and Chlorogenic acid by transforming natural vegetation drug, and decrease the toxic effects and side effects of the natural vegetation. In condition that feedstuff is not added with such harmful additives as antibiotic, quietive and hormone, the adding of the additive of the invention can improve the weight of pig and chicken by 5 to 10 percent, and increase the feedstuff transforming ratio by 5 to 8 percent.

Description

technical field [0001] The invention relates to a preparation method of a feed additive based on biotransformation of natural plant active ingredients, and belongs to the technical field of feed additives. Background technique [0002] Although some progress has been made in the research and development of natural plant feed additive products, and good results have been achieved in the control of livestock and poultry diseases within a certain range, there are still many problems to be solved, such as the large amount of product added, the effective The ingredients are unknown, the mechanism of action is unclear, the effect is unstable, the dosage form is single, the research on toxicology and safety is lacking, the quality control standards of raw materials and products are not complete, etc., resulting in little research and development of new natural plant additives, and new products on the market less. The existence of these problems makes the natural plant feed additiv...
