Problems solved by technology

[0004] At present, most of the Chinese herbal medicine feed additives put on the market are powders or powders. Their production technology is backward, the production equipment is simple, the processing is rough and simple, the variety is single, and the dosage is generally too large. This not only increases the product cost, wastes me

Embodiment 1

[0060] Preparation of Bacillus subtilis culture:

[0061] Obtain Bacillus subtilis fermentation broth by step-by-step expansion culture of slant strains;

[0062] (1) Primary seed culture: Inoculate the slant strain of Bacillus subtilis into a 500 ml shake flask, with a medium capacity of 100 ml, a rotary shaker at 180 rpm, a culture temperature of 40°C, and a culture time of 12 hours;

[0063] (2) Secondary seed cultivation: Put the first-grade seeds into 500 ml second-grade seed shake flasks according to the inoculation amount of 10%, and the cultivation conditions are the same as the first-grade seeds;

[0064] (3) Tertiary seed cultivation: Inoculate the secondary seeds with 10% inoculum volume into a 5000 ml tertiary seed shaker flask, with a medium capacity of 1000 ml, a rotary shaker at 100 rpm, and a culture temperature of 40°C. Time 12 hours;

[0065] (4) First-level seed tank cultivation: put the third-level seeds into the first-level seed tank with a total volume ...

Embodiment 2

[0072] A feed additive comprises the following raw materials in parts by weight: 11 parts of perilla extract, 9 parts of yeast cell wall extract, 25 parts of Bacillus subtilis culture, 7 parts of Astragalus extract; 4 parts of Codonopsis pilosula extract; 3 parts of fructooligosaccharide parts; the above-mentioned ratios are ratios by weight; the preservation number of Bacillus subtilis Li-2013-02 is CGMCC No.7926.

Embodiment 3

[0074] The production method of the feed additive product described in Example 2: the yeast cell wall extract and fructooligosaccharides are crushed through a 60-mesh sieve, and the above-mentioned crushed product is mixed with perilla extract, Bacillus subtilis culture, astragalus extract, and Codonopsis pilosula extract in proportion Mix to obtain the plant extract compound feed additive.

[0075] Preparation of astragalus extract:

[0076] Crush the raw material astragalus until the particle size is less than 2 mm, add 4 times the weight of water to the container and mix evenly, control the temperature at 80°C, keep it for 2.5h, adjust the pH value to 6.2 with lactic acid, cool down to 50°C, add mixed enzymes, After 3 hours of enzymatic hydrolysis, a mixture of ethanol and propanol 1.5 times the weight of the mixed material was added, the temperature was controlled to 70° C., kept for 3 hours, and filtered; the filtrate was concentrated in vacuum and then freeze-dried.

Abstract

The invention discloses an efficient feed additive and a preparation method thereof and belongs to the field of feed additives. The feed additive comprises the following raw materials in parts by weight: 10-15 parts of a perillae extract, 5-10 parts of a yeast cytoderm extract, 15-30 parts of a bacillus subtilis culture, 5-8 parts of an astragalus membranaceus extract, 3-6 parts of a codonopsis pilosula extract and 2-6 parts of fructo-oligosaccharide. The feed additive is small in use amount, stable in performance and safe to use; the astragalus membranaceus extract, the codonopsis pilosula extract and the perillae extract are reasonably matched with the bacillus subtilis culture and the extraction rates of beneficial components including amino acids, polysaccharides, microelements and the like in Chinese herbal medicines are increased; bacillus subtilis is used for promoting the growth of beneficial anaerobic bacteria, reducing the PH (Potential of Hydrogen) value of intestinal tracts and improving intestinal flora; the digestion and the absorption of the beneficial components in Chinese herbal medicines in a feed are promoted effectively; the production performance and the stress performance of livestock and poultry are enhanced and the comprehensive benefits of feeding are increased; the daily gain of animals and the feed conversion rate are improved and the usage amount of the feed is saved.

Description

Technical field: [0001] The invention belongs to the field of feed additives, in particular to a high-efficiency feed additive containing various traditional Chinese medicine components and a preparation method thereof. Background technique: [0002] With the rapid development of animal husbandry in our country, the application of feed additives has become more and more extensive, which has made great contributions to ensuring the healthy development of animal husbandry and meeting people's demand for animal food, but it has also brought a series of problems. Since most of the additives belong to chemically synthesized drugs, such as hormones, antibiotics, etc., while increasing the production of livestock and poultry, the drug residues in livestock products increase, which directly endangers human health; and in the process of modern livestock and poultry breeding, in order to prevent And to treat animal diseases, excessive antibiotic products are often used to ensure anima...
