Embodiment 1

[0012] An immune enhancer for adult Portunus trituberculatus, weighed according to the following parts by weight: levamisole 5, astaxanthin 15, inosine nucleotide (IMP) 20, β-1,3-glucan 30. Seaweed polysaccharide 30. The above raw materials are uniformly mixed to prepare an immune enhancer.

[0013] In the formula of the above immune enhancer, β-1,3-glucan is the extract of brewer’s yeast cell wall, which is obtained by extracting the yeast cell wall after ultrasonic wave breaking, and the β-1,3-glucan in the yeast extract The concentration is 20%.

Embodiment 2

[0015] An immune enhancer for Portunus trituberculatus, which is basically the same as Example 1, except that in the raw material formula: levamisole 8, astaxanthin 17, inosine nucleotide (IMP) 15, β- 1,3-glucan 25, seaweed polysaccharide 35, the above-mentioned raw materials are uniformly mixed to prepare an immune enhancer.

Embodiment 3

[0017] An immune enhancer for Portunus trituberculatus, which is basically the same as Example 1, except that in the raw material formula: levamisole 10, astaxanthin 20, inosine nucleotide (IMP) 10, β- 1,3-glucan 20, seaweed polysaccharide 40, the above-mentioned raw materials are uniformly mixed to prepare an immune enhancer.

Abstract

The invention discloses an immunopotentiator for an adult portunus trituberculatus and an application thereof. The immunopotentiator is characterized by being prepared by evenly mixing the following raw materials in parts by weight: 5-10 parts of levamisole, 15-20 parts of astaxanthin, 10-20 parts of hypoxanthine nucleotide, 20-30 parts of beta-1,3-glucan, and 30-40 parts of seaweed polysaccharides. The mass percentage content of the immunopotentiator in a feeding feed is 0.06-0.08%. The immunopotentiator has the advantages that: the addition amount of the immunopotentiator in the feed is only 0.06-0.08%, thus the immunity and the disease resistance of the adult portunus trituberculatus are significantly improved, so as to improve the survival rate of breeding portunus trituberculatus, wherein the survival rate can be increased by 26% or more, and the immune protection rate can reach 59% or more; and the immunopotentiator has no toxic or side effect, no residue and no drug resistance, also has no adverse effect on the feed palatability, has less addition amount, and can significantly improve the efficacy of the immunity and the disease resistance of the adult portunus trituberculatus.

Description

technical field [0001] The invention relates to an immunomodulator of crabs, in particular to an immune enhancer for adult crabs of Portunus trituberculatus. Background technique [0002] In recent years, with the popularization of crab intensive farming technology, the incidence of crab farming has increased greatly; in order to reduce the loss of farming, a large number of antibiotics have been used, which has led to increased resistance to bacterial diseases; in addition, due to the use of antibiotics in the breeding process And the food safety problem that causes cultured crab has caused people's widespread concern. In order to improve the disease resistance of cultured crabs, it is necessary to develop additives to improve the immunity of crabs. Currently, the widely used immune enhancers mainly include Chinese herbal medicine preparations, polysaccharide preparations, small peptide preparations and nutritional preparations. The curative effect of Chinese herbal prepar...
