Embodiment 1

[0126] Preparation of embedded materials of natural antibacterial components

[0127] (1) Extraction of active ingredients

[0128] Weigh the following medicinal materials in the following proportions by weight: 60 parts of oregano, 30 parts of thyme, 25 parts of cinnamon, 10 parts of honeysuckle, 15 parts of Houttuynia cordata, 10 parts of Astragalus, dust and impurities, and crushed to a length of less than 2cm, a total of Scrap 3300g, with 20L distilled water and 2L absolute ethanol as the solvent, flash extraction for 2min in a flash extractor, repeat the extraction 3 times, control the extraction temperature to 60℃, filter, and collect the filtrate; filter residue with 5 times the mass Disperse in 90% ethanol aqueous solution, extract with ultrasonic vibration at 50℃ and 300W for 45min, filter, dry the filtered medicinal material filter residue, pulverize, and save for later use (as one of the fermentation raw materials); extract the filtrate obtained by ultrasonic vibration ...

Embodiment 2

[0132] Strain cultivation and compound bacterial liquid preparation

[0133] (1) Strain culture

[0134] The suitable strains of the present invention are conventional feedable strains or edible strains.

[0135] The selected strains in this embodiment include: selected from Lactobacillus platarum (Lactobacillus platarum)

[0136] The lactic acid bacteria, Bacillus subtilis, complex yeast (any combination of Candida utilis and Saccharomyces cerevisiae), and Enterococcus faecalis. The strains are selected according to the feedable strains in the "Catalogue of Feed Additives" (promulgated by the Ministry of Agriculture); specifically, it is preferably Bacillus subtilis

[0137] CCTCC NO: M 2011328, Lactobacillus plantarum CICC NO: 21790 and Candida utilis CICC NO: 31430 etc.

[0138] S1: Cultivation of strains

[0139] Lactic acid bacteria and Enterococcus faecalis culture: Lactobacillus and Enterococcus faecalis are inoculated into slant medium (slant medium: beef extract 0.4%, peptone ...

Embodiment 3A

[0151] The preparation of mixed secondary fermentation material A includes the primary fermentation of the fermentation base material and the mixed secondary fermentation of the mixture. The specific steps are as follows:

[0152] Bottom: S1: select the composite bacterial liquid and Enterococcus faecalis bacterial liquid prepared in the above examples; S2: selection and preparation of fermentation raw materials

[0153] The fermentation raw material is composed of fermentation base material, medicinal material filter residue after extracting natural antibacterial components, and fermentation assistant. The fermentation base material is composed of defatted soybean meal, bran, corn germ meal, corn husk and dephenolic cotton meal. The specific composition of the fermentation raw materials is: 40 parts of defatted soybean meal, 20 parts of wheat bran, 25 parts of corn germ meal, 5 parts of dephenolic cotton meal; 3 parts of natural antibacterial extract filter residue; auxiliary: 0.6 ...

Abstract

The present invention provides a microbial fermented composite antibiotic-free feed containing natural antibacterial components. The feed comprises a fermented product based on the united segmented fermentation of aerobic-anaerobic composite strains, composite natural antibacterial components, a non-plant source protein/polypeptide compound nutrient supplement agent, and an additive comprising atleast a soybean protein amino acid/polypeptide compound chelate. The composite strains comprises at least lactic acid bacteria, bacillus subtilis, yeast selected from candida utilis or saccharomyces cerevisiae, and enterococcus faecalis. The fermented product based on the united segmented fermentation is prepared by carrying out secondary fermentation on fermentation raw materials through the aerobic-anaerobic composite strains. The combination of the microbial fermented feed and the natural antibacterial components is beneficial to the balance of intestinal flora of animals, and can prevent the dysbacteriosis of digestive tracts, improve the immunity functions of animal organisms, reduce or replace the use of feed antibiotics, and significantly improve the digestion and absorption efficiency of the feed and the meat quality of animals.

Description

Technical field [0001] The invention relates to the field of fermented feed and production, in particular to a microbial fermented feed compounded with natural antibacterial component embedded materials and additives and a preparation method thereof. Background technique [0002] According to scientific theories and the characteristics of energy metabolism of poultry and livestock, modern animal husbandry can scientifically specify reasonable energy and the amount of various nutrients required for each animal. In order to maximize the use of energy, this modern breeding standard is increasingly The more refined. However, traditional feeds in the aquaculture industry, such as corn, soybean meal, and bran, are gradually being used in modern feed standards. On the one hand, these crude raw materials are difficult to be completely digested and absorbed by animals and the heat utilization rate is low; and the nutrition is not balanced. Therefore, farms are increasingly using feed add...
