A kind of feed additive and preparation method thereof

Abstract

Belonging to the field of feed additives, the invention discloses a feed additive and a preparation method thereof. The feed additive comprises the following raw materials by weight: 20-35 parts of an astragalus extract; 10-20 parts of a Codonopsis pilosula extract; 10-20 parts of a radix bupleuri extract; and 10-25 parts of a bacillus subtilis culture. The product provided by the invention has the characteristics of small usage, stable performance, use safety, and no incompatibility with other feed additives. The Chinese herbal extracts and a microbial agent are adopted in a reasonable proportion, enzymolysis and ethanol immersion extraction are employed to improve the extraction rates of amino acid, polysaccharide, trace elements and other beneficial ingredients in Chinese herbal medicines, and then by combining with the bacillus subtilis culture with high enzyme yield, digestion and absorption of beneficial Chinese herbal ingredients in feed can be promoted effectively. At the same time, the usable value of energy and protein of various feed resources is also enhanced, the production ability, the stress response and raising comprehensive benefits of livestock and poultry are strengthened, the animal daily gain and feed conversion rate are improved, and the drug usage 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...

AI Technical Summary

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 medicine, but also affects The nutrient ratio of the feed is not satisfied. 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.
