Microbial fermentation aquatic feed and preparation method thereof

Abstract

The invention discloses a microbial fermentation aquatic feed, which comprises the following raw materials (by weight): 46-48% of corn gluten feed, 5-8% of corn, 12-15% of soybean meal, 30-32% of water, 1.9-2% of molasses, 0.1-0.2% of complex microbial inoculants, and the balance of auxiliary materials, wherein the complex microbial inoculants are composed of bacillus subtilis, bacillus licheniformis, photosynthetic bacteria, saccharomycetes and lactobacillus according to the mass ratio of (1-1.2) to (0.5-0.6) to (0.1-0.2) to (0.2-0.3) to (0.1-0.3). A preparation method of the microbial fermentation aquatic feed comprises the following steps: Step 1, respectively activating bacillus, photosynthetic bacteria, saccharomycetes and lactobacillus with water and molasses for 18 hours to obtain activated strains; Step 2, mixing and evenly stirring the activated bacterial liquid and a base material and putting into a plastic bag and sealing, and fermenting for 5-7 d in an environment of 20-35DEG C to obtain the fermention feed. Multi-strain composite fermentation is adopted, the ratio of the strains is reasonable, the remarkable synergistic effect is achieved, and the fermentation feed isgolden yellow, has fragrant and sweet wine fragrance, is thick and mellow in smell and free of acid odor and decay smell, has long storage time at the normal temperature and can be stored for two months or above. The longer the storage time is, the more wine fragrance is.

Description

technical field [0001] The invention relates to the technical field of microbial fermentation, in particular to a microbial fermented aquatic feed and a preparation method thereof. Background technique [0002] With the development of the breeding industry, the output of poultry and livestock products is getting higher and higher, and the demand for feed is also increasing day by day. But existing antibiotics are added, and animals have long-term consumption of feeds with added antibiotics, which is prone to adverse effects, and the antibiotics in the body enter the human body through the dining table, affecting human health. [0003] With the improvement of people's health awareness, microbial fermented feed has been developed, which regulates the micro-ecological balance in animals by supplementing beneficial bacteria. It kills pathogenic bacteria and acts as a biological barrier to protect intestinal health, prevent intestinal diseases, increase animal immune function, a...

AI Technical Summary

Problems solved by technology

[0004] The current microbial fermented feed has the following deficiencies: (1) Yeast and lactic acid bacteria or Bacillus subtilis and lactic acid bacteria are mostly used in combination, the strains are single, and the composition of the strains and strains is unreasonable, and the microbial fermented feed cannot be fully utilized. The efficiency of the fermented feed will cause the smell of the fermented feed to be sour and stinky, not sweet, and the storage period of the fermented feed is very short, and it will smell bad if it is slightly broken or leaked, and it is inedible; (2) using a single strain of bacteria Liquid-phase fermentation has complicated process and the production process is easily polluted by miscellaneous bacteria; (3) most of the fermentation technologies have more strains and less substrates, and the finished products are not easy to use in large quantities in actual production, and the dosage of most strains is all below 3%. Using too much will have adverse effects, such as diarrhea, decreased palatability, etc.
