Embodiment example 1

[0048]In the outbreak season of viral grass carp hemorrhagic disease, choose tea polyphenols with an EGCG content of more than 60%, and spray the whole pond at the mouth of the grass carp breeding pond at around 9 am on a sunny day for two consecutive days. Do the same for the situation.

[0049] Various crude drugs that the present invention adopts are commercially available products.

Embodiment example 2

[0051] During the transportation of grass carp seedlings, tea polyphenols with an EGCG content of more than 60% are selected for high-concentration soaking.

[0052] Various crude drugs that the present invention adopts are commercially available products.

Embodiment example 3

[0054] In the feeding process of grass carp, choose tea polyphenols containing EGCG, and feed them with mixing materials.

[0055] Various crude drugs that the present invention adopts are commercially available products.

[0056] Practical operations show that epigallic acid epigallocatechin gallate (EGCG for short) is used as the medicine for preventing and treating viral grass carp hemorrhagic disease or the medicine for preventing and treating viral grass carp hemorrhagic disease in the embodiment one, two and three, which can be well Prevent the death of grass carp due to viral grass carp hemorrhage disease, and greatly improve the survival rate of grass carp.

Abstract

The invention relates to a medicine for preventing hemorrhagic disease of grass carps. The invention provides a medicine for preventing the hemorrhagic disease of grass carps. The medicine is characterized by comprising epigallocatechin gallate. The medicine can be used for well preventing the death of the grass carps caused by the virus hemorrhagic disease of the grass carps, thus greatly improving the aquaculture of the grass carps, and increasing the survival rate in the transportation process.

Description

technical field [0001] The invention relates to a medicine for preventing and treating grass carp hemorrhagic disease, in particular to the application of epigallic acid epigallocatechin gallate (abbreviated as EGCG) as a medicine for preventing and treating viral grass carp hemorrhagic disease. Background technique [0002] Grass carp (Grass carp, Ctenopharyngodon idellus) is an important freshwater aquaculture species in my country, and its aquaculture volume is about 23% of the total aquaculture volume, and the annual production reduction due to diseases will account for more than 30% of the annual grass carp total aquaculture volume. Among all the pathogens of grass carp, Grass carp reovirus (GCRV) is the most harmful and causes the largest reduction in production. Grass carp hemorrhagic disease caused by its infection is a highly contagious and highly lethal viral disease , is one of the most prominent problems in freshwater aquaculture in my country. [0003] The main ...
