Aquaculture feed additive

Abstract

The invention provides an aquaculture feed additive. The aquaculture feed additive is prepared from the following raw materials in parts by weight: 50-85 parts of imported fish bone meal, 10-35 partsof potato dry powder, 1-5 parts of beer yeast, 1-5 parts of a vitamin mixture, 1-6 parts of calcium dihydrogen phosphate, 1-3 parts of mineral salt, 1-5 parts of dried small shrimp powder, 4-8 parts of taurine, 8-15 parts of radix astragali, 7-14 parts of Chinese rhubarb, 3-8 parts of oyster powder, 3-6 parts of vitamin B12, 3-6 parts of vitamin C, 2-5 parts of cane sugar and 2-4 parts of starch,wherein the radix astragali is subjected to anaerobic fermentation with lactobacilli, and the Chinese rhubarb is subjected to anaerobic fermentation with lactobacilli. According to the aquaculture feed additive disclosed by the invention, the choleresis quantity of aquatic animals can be increased, smooth biliary tracts are promoted, cholestatis is eliminated, fat metabolism is promoted, substances of fat, fat-soluble vitamins, cholesterol and the like in foods can be sufficiently digested, the organism immunity function of the aquatic animals is strengthened, and the absorption quantity of bacterial toxins in bodies of the aquatic animal is reduced.

Description

technical field [0001] The invention belongs to the technical field of aquaculture, and in particular relates to an aquaculture feed additive. Background technique [0002] At present, due to the unreasonable design of feed formula, the deterioration of the aquaculture water environment, the long-term use of chemicals, and the stimulation of strong stress such as artificial fishing and pulling nets, the livers of aquatic animals, especially grass carp and crucian carp, etc., have caused great damage. damage and induce hepatobiliary syndrome in fish. For example, grass carp is a kind of aquatic animals, and it is also one of the aquatic species widely cultivated in my country. With the development of grass carp farming towards high density and intensification, and with the extensive use of antibiotics, etc., there has been a high incidence in recent years. Sexual hepatobiliary syndrome disease, the mortality rate is generally high. The commercially available feed additives f...
