Embodiment 1

[0027] Preparation of prawn Chinese herbal compound polysaccharide immune-enhancing feed additive and breeding feed

[0028] Firstly, the immune polysaccharide of Chinese herbal medicine is prepared, and the water extraction method is adopted for extraction. After the pieces of astragalus, atractylodes, and windproof are evenly crushed, mix uniformly according to the mass volume ratio of 1:12 with distilled water, and cook 2 times each time. Ethanol to make the final ethanol content to 70%, let it stand overnight, and suction filter to obtain the crude extract of astragalus polysaccharide, the crude extract of Atractylodes macrocephala polysaccharide and the crude extract of Fangfeng polysaccharide;

[0029] Then extract Astragalus polysaccharide, Atractylodes macrocephala polysaccharide and Fangfeng polysaccharide respectively from the crude extract of Astragalus polysaccharide, crude extract of Atractylodes macrocephala polysaccharide and crude extract of Fangfeng polysaccha...

Embodiment 2

[0033] Effects of a Chinese herbal compound polysaccharide immunoenhancing feed additive for shrimp on the non-specific immunity of Litopenaeus vannamei.

[0034] In this experiment, the inventor fed the prawn Chinese herbal medicine compound polysaccharide immune-enhancing feed additive prepared in Example 1 to Litopenaeus vannamei, and studied the effect of the present invention on improving the immunity of Litopenaeus vannamei by analyzing the non-specific immune indicators of Litopenaeus vannamei. Effect.

Abstract

A Chinese herbal medicine compound polysaccharide immunity-enhanced feed additive for prawns has the characteristic of enhancing immunity and disease resistance of the prawns. The additive is preparedfrom active ingredients of Chinese herbal medicines in percentage by mass as follows: 40%-70% of astragalus polysaccharide, 10%-20% of rhizoma atractylodis macrocephalae polysaccharide and 10%-40% ofsaposhnikovia divaricata polysaccharide. The additive is simple to prepare, lower in cost and convenient to use. After being produced and applied, the preparation can effectively improve the immune defense capacity of the prawns, prevent and treat diseases of the prawns and reduce use of antibiotics and chemical drugs, meanwhile, the problems of effective component uncertainty, multiple impurities, poor palatability and the like caused by addition of original powder of Chinese herbal medicines are solved, and technical support is provided for green and healthy culture of the prawns.

Description

technical field [0001] The invention relates to an immune enhancer for aquaculture, in particular to a prawn Chinese herbal medicine compound polysaccharide immune enhancer feed additive, which belongs to the technical field of aquaculture compound feed additives. Background technique [0002] According to statistics from the Food and Agriculture Organization of the United Nations (FAO), the world's shrimp farming output was 5.18 million tons in 2016, accounting for about 6.5% of the world's total aquaculture output. In recent years, the shrimp aquaculture industry mainly has problems such as the degradation of germplasm and the deterioration of the aquaculture environment, resulting in the decline of the immune function of the shrimp, large-scale disease outbreaks, and a sharp drop in the success rate of aquaculture, which has greatly hindered the healthy and sustainable development of the shrimp aquaculture industry. At present, traditional chemical drugs and antibiotics a...
