Embodiment 1

[0022] Get 30 parts by weight of rhubarb, 30 parts by weight of epimedium, 20 parts by weight of astragalus, and 20 parts by weight of Radix Radix Radix; the above-mentioned components are first coarsely pulverized, then pulverized by an ultrafine pulverizer, and passed through a 120-mesh sieve. Mix well to make immune enhancer.

Embodiment 2

[0024] Growth test: Procambarus clarkii was provided by Lukou base of Jiangsu Freshwater Fisheries Research Institute. Shrimp that are healthy, of the same size and weight are selected for the test, and the initial average weight of each individual is about 7.5g. Randomly divided into groups, there are control group A (feeding basal ration), control group B (adding 1.0% rhubarb to basal ration), and control group C (adding 0.5% rhubarb and 0.5% epimedium to basal ration ) and the test group (adding 1.0% of the Chinese herbal medicine immune enhancer prepared in Example 1 to the basal diet), 3 parallel experiments were set up in each group, 50 test shrimps in each parallel group, and a total of 6 cement ponds (2.50m×2.5 m×0.8m). After 7 days of domestication, the shrimps were fed with the basic diet of the control group and 1.0% Chinese herbal immune enhancer for 60 days, and their growth and immunity indicators were measured.

Embodiment 3

[0037] Get 30 parts by weight of rhubarb, 25 parts by weight of epimedium, 15 parts by weight of astragalus, and 15 parts by weight of Radix Radix; the above-mentioned components are first coarsely pulverized, then pulverized by an ultrafine pulverizer, and passed through a 120-mesh sieve. Mix well to make immune enhancer.

Abstract

The invention discloses a Chinese herbal medicine immunopotentiator for resisting white spot syndrome virus (WSSV) of procambarus clarkia, as well as a preparation method and an application thereof. The preparation method comprises the following steps: milling rheum officinale, epimedium, astragalus membranaceus and isatis root and fully mixing the ingredients in proportion to prepare the powdery immunopotentiator. The Chinese herbal medicine immunopotentiator disclosed by the invention is stable and wide in raw material resources, simple to prepare, and low in cost, is based on the immunomechanism of shellfish to provide Chinese herbal medicines for the shellfish, and can be used for improving the immunity and oxidation resistance of a body during application, improving the capacity of the procambarus clarkia for resisting WSSV infection, and promoting the growth of the procambarus clarkia.

Description

technical field [0001] The invention belongs to the field of aquaculture, and relates to a procambarus clarkii anti-white spot syndrome virus Chinese herbal medicine immune enhancer and a preparation method and application thereof.
