Problems solved by technology

[0002] One of the more important problems facing the aquaculture industry at present is that the use of many auxin and drug feed additives causes a large amount of drug residues, resulting in a decline in poultry and livestock meat varieties. After eating, the drug will be enriched in a large amount, which will lead to the enhancement of bacterial drug resistance and directly or indirectly affect human health.

Abstract

The invention belongs to the field of microbial fermentation, and relates to compound microbial feed additives containing lactobacillus casei, lactobacillus acidophilus, lactobacillus plantarum and the corresponding absorbing carriers of the strains mentioned above and the preparation method thereof. By adopting the compound microbial feed additives, a great amount of active microorganisms can besupplemented within a short term to balance the intestinal flora of livestock and fowl, thereby releasing the unbalance caused by pathological mechanism or drug taking effectively and improving the immunity of the organisms of the livestock and fowl at the same time; the microbial feed additives can be added in the feed as organic production means, and can replace the antibiotics and chemicals partially or even completely, thereby reducing the breeding cost directly and the feed / meat ratio, improving the feed digestibility of the livestock and fowl and the return rate of feeding stuff; and the microbial feed additives has simple preparation process, and the preparation method is suitable for industrial application.

Description

technical field [0001] The invention belongs to the field of microbial fermentation, and relates to a compound microbial feed additive containing Lactobacillus casei, Lactobacillus acidophilus, Lactobacillus plantarum and corresponding adsorption carriers and a preparation method thereof. Background technique [0002] One of the more important problems facing the aquaculture industry at present is that the use of many auxin and drug feed additives causes a large amount of drug residues, resulting in a decline in poultry and livestock meat varieties. Drugs are enriched in a large amount after consumption by the consumers, which leads to the enhancement of bacterial drug resistance and affects human health directly or indirectly. How to adopt some new feed additives to reduce the side effects of drug-type feed additives, and at the same time replace some drug-type feed additives to a certain extent, is the current and future research direction for a long period of time.
