Problems solved by technology

The prevention and treatment of diseases with rice medicine and lobster culture is a major problem in rice field shrimp farming. Feeding Procambarus clarkii with natural bait will cause unbalanced nutrient intake during the breeding process, resulting in slow growth, low disease resistance, and poor quality. The decline of water quality and the deterioration of water quality are not conducive to the development of intensive and efficient artificial culture of Procambarus clarkii

Abstract

The invention provides an additive capable of improving the immunity of crayfish bred in a rice field and a preparation method thereof. The additive comprises the following raw materials: wheat flour, corn flour, fish meal, fish oil, soya bean lecithin, L-lactic acid, choline, betaine, composite vitamin, composite trace elements, cellulose and dextrin. The preparation method comprises the following steps: mixing the wheat flour, corn flour and fish meal and carrying out drying and crushing so as to obtain mixed powder; adding L-lactic acid, choline, betaine, composite vitamin and composite trace elements into a sodium alginate solution and carrying out heating and heat preservation so as to obtain mixed liquor; and mixing the mixed powder and the mixed liquor with the fish meal, fish oil, soya bean lecithin, cellulose and dextrin and carrying out spray drying so as to obtain the additive. The additive provided by the invention can improve the body-weight increase rate of the crayfish and reduce the content of MDA and the activity of SOD in the hepatopancreas of the crayfish.

Description

technical field [0001] The invention belongs to the technical field of lobster feed, and in particular relates to an additive for improving the immunity of paddy field cultured crayfish and a preparation method thereof. Background technique [0002] Procambarus clarkii (Procambarus clarkii) belongs to Crustacea, Molluscilla, Decapod, Reptilia, Crawfishidae, Procambarus genus, is a lobster-like crustacean that lives in fresh water, so it is commonly known as crayfish. Procambarus clarkii is native to North America, and it has an absolute competitive advantage in the ecological environment because of its omnivorous, fast growth, and strong adaptability. It is the most widely distributed alien invasive species of crustaceans. Because of its fresh and tender meat and rich nutrition, it has become an important economic variety in my country. [0003] Breeding freshwater crayfish in paddy fields is a production method to improve the efficiency per unit area of ​​paddy fields, ...
