Abstract

The invention discloses seaweed meal with an adhesive effect for an aquatic feed. The seaweed meal comprises the following raw materials in parts by weight: 5-15 parts of enteromorpha, 0-15 parts of ulva, 25-45 parts of kelp, 15-30 parts of undaria pinnatifida, 5-15 parts of gulfweed, 5-20 parts of laver, and 15-20 parts of gracilaria. A preparation method of the seaweed meal comprises the following steps of mixing seaweed in proportion; performing grinding and enzymolysis to obtain processed seaweed; adding the processed seaweed in a carrier; mixing the processed seaweed with the carrier to obtain a mixture; drying the mixture; and crushing the dried mixture. The seaweed meal is prepared from natural algae, so that the seaweed meal is high in adhesive effect, the stability of bait in water can be enhanced, and the powder yielding rate during processing can be reduced; compared with terrestrial plants, the seaweed meal contains mineral elements of iodine, calcium, phosphorus and the like, and contains various vitamins, algal polysaccharides, mannitol and the like, and after enzymolysis, the seaweed meal is easy to absorb and utilize by animals, so that the feed efficiency can be effectively improved, the growth and the development of animals can be promoted, and the disease resisting ability of animal bodies is increased; and the seaweed meal contains unique fishy smell substances and pigment of the seaweed, so that the food-calling properties of the feed can be increased, the body color of cultured fish can be close to natural body color, and the economic benefits of cultivation products are increased.

Description

technical field [0001] The invention relates to a seaweed powder for feed, in particular to a seaweed powder for aquatic feed with binding function, and belongs to the field of biological feed. Background technique [0002] In recent years, the scale of aquaculture in my country has continued to expand, the degree of intensification and industrialization has become higher and higher, the pollution of aquaculture waters has become increasingly serious, and diseases have occurred frequently, which seriously plagued the rapid development of aquaculture. Feed additives are the key technical control points for the intensive development of aquaculture. Some of the existing feed additives have single functions and cannot overcome the problems of low survival rate, high incidence of disease, and slow growth of fish at the same time. Artificially synthesized additives can Effectively solve some problems in aquaculture, but there may be harmful ingredients to the human body, which doe...
