Traditional Chinese medicine fermentation preparation for improving growth performance and immunity of litopenaeus vannamei, and preparing method and application thereof

Abstract

The invention discloses a traditional Chinese medicine fermentation preparation for improving growth performance and immunity of litopenaeus vannamei, and a preparing method and application thereof, and belongs to the technical field of traditional Chinese medicine fermentation preparations. The traditional Chinese medicine fermentation preparation is prepared by fermenting of a mixture of traditional Chinese medicine components and pediococcus acidilactici bacteria liquid. The traditional Chinese medicine components comprise, by weight, 1.2-2.0 parts of pulsatilla extract, 0.5-1.0 part of coptis chinensis extract, 0.8-1.2 parts of cortex phellodendri extract, 0.8-1.5 parts of cortex fraxini extract, 0.4-0.7 part of nutmeg extract, 0.5-1.0 part of hawthorn extract, 0.1-0.3 part of costusroot extract and 1.0-2.0 parts of liquorice extract. According to the traditional Chinese medicine fermentation preparation for improving growth performance and immunity of litopenaeus vannamei, the preparing method and the application thereof, selected traditional Chinese medicine extracts are reasonable in structure and proper in proportion; selected pediococcus acidilactici is high in activity and stress resistance, and the efficacy of an original medicine is improved remarkably; and the growth performance and immunity of the litopenaeus vannamei can be improved significantly.

Description

technical field [0001] The invention belongs to the technical field of traditional Chinese medicine fermented preparations, and in particular relates to a traditional Chinese medicine fermented preparation for improving the growth performance and immunity of Litopenaeus vannamei, its preparation method and application. Background technique [0002] In recent years, my country's shrimp farming industry has developed rapidly. Although the breeding area and scale of Litopenaeus vannamei in my country are expanding year by year, the degradation of seed resources, the low survival rate of prawns caused by infectious diseases, the high cost of breeding, and the deterioration of the breeding environment have brought huge losses to shrimp farmers. Economic loss has seriously affected the healthy and sustainable development of Litopenaeus vannamei aquaculture. Although the application of antibiotics has achieved certain results, the resulting drug resistance and harm to the environme...
