Problems solved by technology

The production technology of these products is backward, the production equipment is simple, the processing is rough and simple, the variety is single, and the dosage is generally too large
It not only increases the product cost, wastes drugs, but also affects the nutritional ratio of the feed. The existence of these problems also makes the Chinese herbal medicine feed additives on the market do not meet the basic functional principle of "trace amount, high efficiency" feed additives, and it is difficult to realize Industrialization and Standardization

Embodiment 1

[0051] Preparation of Bacillus subtilis culture:

[0052] Obtain Bacillus subtilis fermentation broth by step-by-step expansion culture of slant strains;

[0053] (1) Primary seed cultivation: insert the slant strain of Bacillus subtilis into a 500-milliliter shake flask, with a medium loading capacity of 100 milliliters, a rotary shaker at 180 rpm, a cultivation temperature of 40° C., and a cultivation time of 12 hours;

[0054] (2) secondary seed cultivation: the primary seed is inserted into a 500 milliliter secondary seed shake flask according to the inoculum size of 10%, and the cultivation condition is the same as that of the primary seed;

[0055] (3) Tertiary seed cultivation: the secondary seeds are inserted into 5000 milliliters of tertiary seed shake flasks with 10% inoculum size, the medium loading capacity is 1000 milliliters, the rotary shaker is 100 rpm, and the cultivation temperature is 40 ° C. Time 12 hours;

[0056] (4) First-level seed tank cultivation: c...

Embodiment 2

[0063] A feed additive comprises the following raw materials in parts by weight: 8 parts of yeast cell wall extract, 30 parts of Bacillus subtilis culture, 9 parts of Astragalus extract; 7 parts of Bupleurum extract; score ratio. The preservation number of Bacillus subtilis Li-2013-02 is CGMCC No.7926.

Embodiment 3

[0065] The production method of the feed additive product described in Example 2: the yeast cell wall extract and fructooligosaccharide are crushed through a 60-mesh sieve, and the above crushed product is mixed with the culture of Bacillus subtilis, the extract of Astragalus membranaceus, and the extract of Bupleurum radix in proportion to obtain the feed additive .

[0066] Preparation of astragalus extract:

[0067] Crush the raw material astragalus until the particle size is less than 2 mm, add 5 times the weight of water to the container and mix evenly, control the temperature at 85°C, keep it for 3 hours, adjust the pH value to 6.5 with lactic acid, cool down to 52°C, add mixed enzymes, enzymes After decomposing for 3 hours, add a mixture of ethanol and propanol which is 2 times the weight of the mixed material, control the temperature to 75° C., keep it for 4 hours, and filter; the filtrate is concentrated in vacuum and then freeze-dried.

[0068] The added amount of t...

Abstract

The invention discloses a feed additive and a preparation method thereof, belonging to the field of feed additives. The feed additive comprises the following raw materials in parts by weight: 5-10 parts of a yeast cell wall extract, 25-36 parts of a bacillus subtilis culture, 5-10 parts of an astragalus membranaceus extract, 5-8 parts of a radix bupleuri extract and 2-6 parts of fructo-oligose. The feed additive is small in product use amount, stable in property and safe to use and has no incompatibility with other feed additives, traditional Chinese herbal medicine extracts are reasonably matched with microbial agents, and are matched together with the bacillus subtilis culture with high enzyme yield, digestion and absorption of beneficial components in the traditional Chinese herbal medicines in feed can be effectively prompted, and meanwhile, the energy of various feed resources and the available values of protein can be increased, the production property and the stress property of livestock can be improved, the comprehensive feeding benefits of the livestock can be increased, the daily gain of the livestock and the feed conversion rate can be increased, and the use amount of medicines can be reduced.

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 my country's animal husbandry, the application of feed additives has become increasingly widespread, which has made a great contribution 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 additives belong to chemically synthesized drugs, such as hormones and antibiotics, while increasing the production of livestock and poultry, the drug residues in livestock products increase, which directly endangers human health. In the process of modern livestock and poultry farming, in order to prevent and treat animal diseases, excessive antibiotic products are often used to ensure animal health. However,...
