Abstract

The invention discloses a shrimp ferment, and a preparation method and an application thereof. The shrimp 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 to 1; the solid medium comprises the following ingredients in parts by mass: 25-35 parts of soybean meal, 10-20 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, 0.5-1.5 parts of multi-vitamins, 0.5-1.5 parts of multi-minerals, and 1-5 parts of radix astragali polysaccharides; and thefermentation package comprises the following ingredients in parts by mass: 75-85 parts of lactic acid bacteria, 5-15 parts of bacillus, and 5-15 parts of yeast. The shrimp ferment is rational in proportion, and has the characteristics of comprehensive nutrients, high attractant activity, and feasibility for regulating and stabilizing water; and thus, the shrimp ferment is capable of promoting rapid growth of shrimps, decreasing feed coefficient, enhancing immunity of shrimps, 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 specifically relates to a shrimp enzyme and a preparation method and application thereof. Background technique [0002] Academician McConson proposed: Aquaculture has entered the age of fermentation. Fermented products are now receiving more and more attention in aquaculture. Penaeus vannamei has fast growth, high meat yield, strong resistance to stress, and is especially suitable for a wide range of salinity. It can be cultured in near fresh water, and has become the world's highest aquaculture production of shrimp species. However, with people's blind pursuit of high yields, the increasing stocking density, the continuous deterioration of the aquaculture water environment caused by the large amount of bait, and the large-scale outbreak of infectious diseases have severely restricted the further development of the shrimp aquaculture industry. [0003] Lactic acid ...
