Method for preparing grass carp feed additive containing traditional Chinese medicine active probiotics

Abstract

The invention discloses a method for preparing a grass carp feed additive containing traditional Chinese medicine active probiotics, comprising the following steps: respectively carrying out amplification culture of the strain number of a single bacterial specie on original strains of active probiotics for grass carps; mixing primary seed liquors of active probiotics for grass carps with same weight, inoculating the mixture in a seed tank medium to carry out multiple-strain mixed culture, then inoculating in a traditional Chinese medicine liquid medium to carry out a primary traditional Chinese medicine fermentation; and mixing the multiple-strain mixed traditional Chinese medicine fermentation liquor with isometric cob powder to obtain solid fermentation seeds, and then inoculating in a traditional Chinese medicine solid medium to carry out a secondary traditional Chinese medicine fermentation. According to the invention, the strain activity and colonization performance in the intestinal tracts of active probiotics in the grass carp feed additive are improved greatly, the prepared grass carp feed additive is rich in traditional Chinese medicine components, the active components with pharmacological effects in the traditional Chinese medicine components fully play the role, thus the performances of strengthening the body, treating diseases and promoting growth of the grass carp feed additive are improved, and the grass carp feed additive can effectively treat and prevent four diseases of grass carps, and furthermore completely displace antibiotics.

Description

Technical field [0001] The invention relates to the field of aquaculture, and in particular to a method for manufacturing a grass carp feed additive containing active probiotics of traditional Chinese medicine. Background technique [0002] Grass carp is one of many freshwater fish in our country. It is loved by consumers for its tender meat, large individual and few intermuscular spines. However, grass carp has poor disease resistance and low survival rate. It is extremely vulnerable to the "four diseases of grass carp (grass carp, red skin disease, gill rot disease, enteritis disease and hemorrhagic disease)" during the breeding process. Therefore, the scale of grass carp Chemical breeding has been greatly restricted. Long-term production practices have proved that injecting antibiotics into grass carp can prevent the "four diseases of grass carp"; however, these antibiotics will enter the human body as people eat various fish and meat products, which indirectly leads to the a...

AI Technical Summary

Problems solved by technology

In the existing production process of microecological feed additives for fish, most of them only use protein substances and / or sugar substances as the culture medium for active probiotics. Although the number of strains can meet the demand, the activity of most strains is not high , the colonization performance in the intestinal tract is weak, so the role of active probiotics as livestock and poultry feed is greatly limited; at the same time, active probiotics can only enhance the physique of grass carp to a certain extent, and cannot effectively treat and prevent "Four diseases of grass carp", therefore, the existing grass carp microecological feed additives cannot completely replace the use of antibiotics
