Eel ferment, and preparation method and application thereof

Abstract

The invention discloses an eel ferment, and a preparation method and an application thereof. The eel ferment is composed of a solid medium and a fermentation package, wherein the mass ratio of the solid medium to the fermentation package is 9.2 to 0.8; the solid medium comprises the following ingredients in parts by mass: 10-15 parts of fermented soybean meal, 8-12 parts of corn, 10-20 parts of middlings, 5-15 parts of peanut meal, 5-15 parts of fish meal, 3-8 parts of molasses, 0.2-0.4 part of fish oil, 0.5-1.5 parts of multi-vitamins, 0.5-1.5 parts of multi-minerals, and 1-5 parts of radix astragali polysaccharides; and the fermentation package comprises the following ingredients in parts by mass: 70-80 parts of lactic acid bacteria, 5-15 parts of bacillus, and 10-20 parts of yeast. Theeel ferment is capable of promoting rapid growth of eels, as well as reducing feed coefficient so as to decrease breeding cost; moreover, the eel ferment is capable of enhancing immunity of eels, regulating stability of aquatic water, reducing aquaculture risk, and increasing aquaculture success rate.

Description

technical field [0001] The invention belongs to the technical field of aquatic feed and raw material processing, and in particular relates to an eel enzyme and its preparation method and application. Background technique [0002] Academician McConson pointed out that aquaculture has entered the era of fermentation; now fermented products are getting more and more attention in aquaculture. Eels spawn and reproduce in the deep sea and grow in freshwater environments. Fierce temperament, gluttonous, restless, nocturnal, strong phototropism, fond of running water, very warm. Adult eels grow fast, round and cone-shaped in appearance, black in color and firm in body, mostly artificially bred, and crisp in texture. This fish is common all year round, but it is the most plump and delicious in summer and winter. Eel is rich in nutrition, delicious in taste, less thorny and more fleshy, and has the functions of cooling and relieving heat, nourishing and strengthening the body. How...

Problems solved by technology

[0007] There is no fermented feed used by eel on the market, but there are fermented feeds used by other aquatic animals, such as the fermented feed used by fish and shrimp, but there are many problems, many of which are not perfect in fermentation technology, easy to contaminate miscellaneous bacteria, fermentation is relatively simple, raw materials The fermentation is not thorough enough, the type and quantity of beneficial bacteria fermented are not reasonable enough; the quality and proportion of solid medium and whether the particle size is reasonable, etc.
