Abstract

The invention relates to a Chinese herbal medicine feed additive, in particular to a Chinese herbal medicine feed additive for penaeus vannamei and a preparation method and application thereof. The Chinese herbal medicine feed additive is prepared from the following components in percentage by weight: 25%-35% of radix scutellariae, 25%-35% of the fruit of Chinese magnoliavine, 15%-25% of sappan lignum, 5%-15% of rough gentian, and 5%-15% of cassia seed. Compared with the prior art, the Chinese herbal medicine feed additive has the following beneficial effects that on the basis of reviewing antibacterial experiments in vitro, drugs having antibacterial ability in vitro are added to a feed for further verification, and the number of vibrio in penaeus vannamei and the physical conditions thereof are evaluated to obtain a combination of drugs, and the experiments prove that the Chinese herbal medicine feed additive can directly inhibit and exterminate bacteria and better improve the anti-stress ability of penaeus vannamei.

Description

technical field [0001] The invention relates to a Chinese herbal medicine feed additive, in particular to a Chinese herbal medicine feed additive for Penaeus vannamei and its preparation method and application. Background technique [0002] Penaeus vannamei is currently the crustacean species with the highest aquaculture output in the world. It is suitable for a wide range of salinity and can be cultured in brackish and fresh water areas. In addition, it grows rapidly and has a high meat yield, and has rapidly developed in coastal and inland areas. [0003] However, in recent years, the incidence of Penaeus vannamei has been very serious, and for a long time, the loss has been heavy. Especially since 2009, the disease began to develop soon after the seedlings were released, and the pond discharge rate was very high. At the beginning of 2013, researchers basically confirmed that a special Vibrio parahaemolyticus was the main cause of the disease. The unique plasmid contained...
