Preparation method of traditional Chinese medicinal feed additive for prawns

Abstract

The invention discloses a preparation method of a traditional Chinese medicinal feed additive for prawns. The traditional Chinese medicinal feed additive consists of common traditional Chinese medicines in parts by weight: 17-24 parts of polygonatum kingianum, 15-19 parts of ajuga ciliate, 15-19 parts of radix codonopsis, 13-18 parts of astragalus, 8-14 parts of rhizoma atractylodis, 8-13 parts of isatis roots and 8-13 parts of herba andrographitis. The preparation method comprises the steps of mixing all medicinal materials according to a ratio, processing the medicinal materials into medicine powder of 50-70 meshes, adding 30% pure water and a proper amount of red sugar into the medicine powder for natural fermentation to form ferments, extracting residual medicine slag of ferment liquid, and performing high-speed slurrying machine to obtain paste; fully mixing the paste with purified high-quality bacillus and high-quality yeast for further fermentation for 36 hours to obtain the traditional Chinese medicinal feed additive for the prawns.

Description

technical field [0001] The invention relates to the technical field of feed production, in particular to the technical field of production of traditional Chinese medicine feed additives for aquaculture. Background technique [0002] The aquaculture industry has become an important pillar industry in my country, and the shrimp aquaculture industry occupies a very important proportion in aquaculture. With the continuous development and expansion of the scale of prawn farming, more and more problems are exposed in the process of farming, such as low survival rate, high incidence rate, slow growth rate and so on. At present, in response to these problems, farmers often add feed additives containing chemical drugs, antibiotic drugs and hormones to the compound feed for prevention and treatment, which will not only cause drug residues in the prawn meat, but also pollute the water quality and affect the environment. . Moreover, if the consumer eats such prawns, it will also bring...

AI Technical Summary

Problems solved by technology

At present, in response to these problems, farmers often add feed additives containing chemical drugs, antibiotic drugs and hormones to the compound feed for prevention and treatment, which will not only cause drug residues in the prawn meat, but also pollute the water quality and affect the environment.

Moreover, if consumers eat such prawns, it will also bring harm to consumers' health.

Even in this way, the situation of the existing prawn farming industry has not been improved, and problems such as low survival rate, high morbidity rate, and slow growth rate of prawns cannot be overcome.
