Biological fermented feed for crayfishes and preparation method thereof

Abstract

The invention discloses a biological fermented feed for crayfishes and a preparation method thereof. The biological fermented feed for crayfishes comprises fermentation raw materials and a microbial strain accounting for 0.1-0.5% of the mass of the fermentation raw materials; and the fermentation raw materials comprise the following materials in parts by mass: 40-50 parts of wheat, 30-40 parts of corns and 20-30 parts of soybeans. The biological fermented feed disclosed by the invention is prepared by fermenting the wheat, corns and soybeans, the pH value of the feed is relatively low, and the feed contains more lactic acid and acetic acid, and has characteristics of an acidifying agent and a microbial ecological agent and functions of similar antibiotic growth factors at the same time, so that the feed can significantly enhance animal immunity and improve breeding quality of aquatic animals, thereby promoting healthy development of the modern aquaculture industry.

Description

technical field [0001] The invention relates to the technical field of feed, in particular to a crayfish biologically fermented feed and a preparation method thereof. Background technique [0002] During the development of the breeding industry, additives represented by antibiotics have solved the problems of "fast" and "quantity" of livestock, poultry and aquatic products, and met the needs of human beings. However, with the progress and development of society, antibiotics have brought A series of hazards: First, with the abuse of antibiotics in feed and treatment, animals have developed drug resistance. As a result, the use of antibiotics is increasing, and livestock, poultry and aquatic products are becoming more and more difficult to raise, which directly affects the breeding Second, antibiotic residues in livestock, poultry and aquatic products are becoming more and more serious, directly threatening and affecting human health; third, antibiotics used by animals are mai...

AI Technical Summary

Problems solved by technology

[0002] During the development of the breeding industry, additives represented by antibiotics have solved the problems of "fast" and "quantity" of livestock, poultry and aquatic products, and met the needs of human beings. However, with the progress and development of society, antibiotics have brought A series of hazards: First, with the abuse of antibiotics in feed and treatment, animals have developed drug resistance. As a result, the use of antibiotics is increasing, and livestock, poultry and aquatic products are becoming more and more difficult to raise, which directly affects the breeding Second, antibiotic residues in livestock, poultry and aquatic products are becoming more and more serious, directly threatening and affecting human health; third, antibiotics used by animals are mainly in the form of prototype or metabolites with feces, urine, etc. The excrement is discharged and remains in the environment, which has adverse effects on the ecological environment such as soil and surface water, and has a toxic effect on the ecological environment through the food chain.

[0003] With the rapid development of the crayfish industry in recent years, a farming model based on feeding pellets and full-price feeds has begun to appear in the market. Since the addition of antibiotics is allowed in my country’s feed regulations, this will affect the product quality and brand image of Hubei crayfish. It will cause great hidden dangers and even affect the healthy development of the entire crayfish industry.
