Chinese herbal medicine hepatopancreas protective agent as well as preparation method and application thereof

Abstract

The invention provides a Chinese herbal medicine hepatopancreas protective agent for crayfish, which comprises the following parts in parts by weight: 0.1-0.3 part of bile acid, 1-5 parts of choline chloride, 10-15 parts of glucan, 3-7 parts of taurine, 5-10 parts of astragalus polysaccharide, 0.6-1.0 part of eucommia ulmoides leaf extract, 5-10 parts of dandelion extract, 5-10 parts of honeysuckle extract, 7-13 parts of cassia seed extract, 8-15 parts of galangal extract and 5-10 parts of chrysanthemum extract. The procambarus clarkii hepatopancreas protective agent provided by the invention can improve the hepatopancreas protection capacity of procambarus clarkii in a stress state, ensure the survival rate after transportation, and promote the quick development of the procambarus clarkii breeding industry in Hainan procambarus clarkii.
