Fermentation feed for aquatic products, preparation method thereof and application thereof

Abstract

The present invention discloses a preparation method of a fermentation feed for aquatic products. The preparation method comprises the following steps: 1) bran, soybean meal and corn gluten meal in ratios are weighed, the weighed materials are subjected to dry heat sterilization, and the sterilized materials are crushed to prepare a raw material carrier; 2) mineral substances, koji seeds, carbon sources and plant vitamins are respectively taken, the taken materials are crushed, and the crushed materials are mixed to prepare a strain nutrient agent; 3) the raw material carrier is added into thestrain nutrient agent to be mixed and stirred to be prepared into a mixed feed; 4) water is added into the mixed feed for a sealed fermentation for 1-5 days to be prepared into a wet fermented material; and 5) according to different culture stages of shrimps, the wet fermented material is mixed with a full-price compound feed to be prepared into the fermentation feed for the aquatic products. Thepresent invention also discloses the fermentation feed for the aquatic products and an application thereof. The feed is solid, and convenient in circulation and transportation, greatly improves nutritional levels and digestion and utilization of the fermented material, and is safe.

Description

technical field [0001] The invention belongs to the field of microbial fermented feed, in particular to a fermented feed for aquatic products and its preparation method and application. Background technique [0002] In recent years, my country's aquaculture has developed rapidly, but the high incidence of water pollution caused by high-density farming and excessive feeding is hitting the aquaculture industry hard. At present, the most common use of antibiotics and disinfectants, etc. To prevent and control fish and shrimp diseases and use microecological preparations to improve the aquaculture environment, but with the increasing resistance of pathogenic bacteria and the increasingly serious problems of drug residues, it has become urgent to change the inherent disease prevention and treatment methods, and the application of nutritional immunology Improving the disease resistance of aquatic animals has been considered as an effective means to realize pollution-free ecological ...

AI Technical Summary

Problems solved by technology

[0003] In view of the functions and advantages of fermented feed in application, various technical products related to fermented feed have emerged in aquaculture, and the production technology is also diversified, such as the production process introduced in the following Chinese patent: the application number is The Chinese patent of 201310493374.7 discloses microbial fermented feed for Penaeus vannamei. The preparation of the feed is specifically to fully mix photosynthetic bacteria and bacillus to obtain mixture A, and then obtain mixture B; Sealed fermentation, when the temperature in the center of the sealed container rises to 45°C, the fermentation is completed, the fermented mixture B is taken out, air-dried, and bagged to obtain the product. This invention is simply to ferment the commercially available compound feed, which is suitable for South America The rapid increase in feeding amount in the middle and late stages of whiteleg shrimp culture increases the cost of feed, and the bacteria are single

[0004] The Chinese patent application number 201210583513.0 discloses a production method and application of microbial fermented chicken manure feed, fresh points 60-70%, rice bran 15-25%, bran 5-10%, corn flour 3-5%, microbial 0.2-0.5% of the mixture is mixed and fermented, and the Chinese patent application number 201310701064.X discloses a microbial fermented fish feed and its preparation method. The fish feed consists of chicken manure 80-100, pig manure 100- 150, corn flour 50-60, 24% DDGS wine tank 70-90, bean cake 3-50, rapeseed cake 30-50, wheat bran 40-60, peanut bran 50-70, bone meal 5-7, shell meal 6- 10. Made from the raw materials of Yuduowei 0.2-0.4, Yuduomine 5-8, table salt 2-3, brewer’s yeast 10-15 and molasses 15-20, the above two inventions use fresh chicken manure or pig manure as the main material , although it can save costs, but because the use of chicken manure fermentation is used for food, there are certain quality and safety risks, and it is difficult to ensure the intestinal health of fish and shrimp, so the use of it should not be advocated.

[0005] The application number is 200810023475.7, which discloses antibiotic-free microbial fermented aquatic feed, which consists of microbial fermentation culture, mineral trace elements, multivitamin preparations, food attractants, bran, flour, fish meal, soybean meal, lecithin, fish oil, and micro-ecological water environment. Composed of improver and phytase, its nutrients are single and cannot meet the needs of all microorganisms for different nutrients
