Abstract

The invention relates to a compound Chinese herbal medicine immunopotentiator for prawns. The immunopotentiator is prepared from Chinese herbal medicine active ingredients in percentage by mass as follows: 20%-50% of astragalus polysaccharides, 20%-50% of chlorogenic acid and 20%-50% of berberine. The immunopotentiator can substitute for antibiotics and chemicals after being produced and applied and can significantly enhance the immunity and disease resistance of the prawns. Three Chinese herbal medicine active ingredients of astragalus, eucommia bark and golden thread are extracted and applied to feed, so that adverse effects caused by multiple medicines are avoided; the immunopotentiator is simple to prepare, lower in cost and capable of increasing the economic benefit of the prawn culture industry.

Description

technical field [0001] The invention relates to an immune enhancer for aquatic animal breeding, in particular to a compound Chinese herbal medicine immune enhancer for prawns, belonging to the field of aquaculture. Background technique [0002] In recent years, the shrimp farming industry has developed rapidly. According to the FAO report, the output of shrimp farming in 2012 accounted for about 12.8% of the world's fish farming output, occupying a pivotal position in the aquaculture industry. However, due to the degradation of germplasm resources and the deterioration of the breeding environment, frequent outbreaks of shrimp farming diseases severely restrict the further development of the shrimp farming industry. The traditional way to prevent and control shrimp diseases is to use antibiotics. However, the abuse of antibiotics will lead to serious problems such as drug residues, drug-resistant strains, and environmental pollution. Therefore, looking for alternatives to an...
