A kind of preparation method of fermented prawn compound feed

Abstract

The invention discloses a preparation method of fermented prawn compound feed. The present invention adopts the process of solid and liquid mixed fermentation, preferably produces rich enzymes and can co-grow Aspergillus niger, Bacillus subtilis, and Bacillus licheniformis for joint fermentation, and through aerobic and anaerobic two-step fermentation, fully develop Aspergillus niger and Bacillus licheniformis. The advantages of rich enzymes produced by Bacillus subtilis enable the comprehensive decomposition of basic fermentation raw materials, macromolecular proteins are decomposed into peptides and amino acids, cellulose is decomposed into fermentable sugars, starch is decomposed into fermentable glucose, and xylan is decomposed into Xylose, glucan, etc., so that the growth and reproduction of Lactobacillus reuteri in the anaerobic stage can obtain the support of a large number of nutrients. From indicators such as biological peptide content, L-lactic acid content, and number of colonies, it can be reflected that the growth and metabolism of microorganisms in the aerobic stage and anaerobic stage in the preparation method proposed by the present invention are very vigorous.

Description

Technical field: [0001] The invention belongs to the technical field of aquatic feed and bioengineering, and in particular relates to a preparation method of fermented prawn compound feed. Background technique: [0002] my country's shrimp farming industry has formed a complete industrial system. With the continuous expansion of breeding density and scale, various diseases occur frequently. Bacterial diseases caused by Vibrio spread quickly and have a high infection rate, causing huge damage to the shrimp farming industry. The economic loss has severely restricted the development of shrimp farming in my country and even in the world. Farmers usually use a large amount of antibiotics. Although they have achieved short-term results, they have led to increased drug resistance of pathogenic microorganisms, decreased diversity of microbial communities, drug residues, and deterioration of the breeding environment. The preparation method of the present invention uses several functi...
