Problems solved by technology

At present, a large number of antibiotics and chemical drugs are used in artificially cultured sea cucumbers for disease prevention. However, with the increase of drug resistance of pathogenic bacteria, the dosage of antibiotics and chemical drugs is also increasing. It affects the quality of sea cucumber products and the health of consumers, and pollutes water bodies and the environment
The residual bait of japonicus is rich in nutrients, and after being deposited on the bottom of the pond, it is easy to rot and produce toxic gas under the action of anaerobic bacteria, which seriously threatens the health of japonicus

Embodiment 1

[0014] 30 grams of astragalus, 20 grams of hawthorn, 20 grams of Radix Isatidis, 15 grams of Angelica sinensis, and 15 grams of Schisandra chinensis are mixed uniformly in a mixer in proportion through ultrafine grinding (over 300 meshes) (required coefficient of variation ≤ 5%), and then press 3% The dose is added to the sea cucumber compound feed, and the pellet machine is used to make 3 mm diameter particles. The experiment shows that the weight gain rate increases by 1% after 20 days in the sea cucumber culture; the blood cell phagocytosis rate increases by 66.67%; the superoxide anion production increases 55%; the heat stress survival rate increased by 10%; the bacterial challenge survival rate increased by 50%; after the feed was fed into the water for 12 hours according to the normal feeding amount, the ammonia nitrogen concentration in the experimental group was reduced by 25% compared with the control group.

Embodiment 2

[0016] 35 grams of Radix Astragali, 20 grams of Hawthorn, 15 grams of Radix Radix, 20 grams of Chinese Angelica, and 10 grams of Schisandra Fructus are superfinely pulverized (over 300 mesh) and mixed uniformly in a mixer in proportion (required coefficient of variation ≤ 5%), and then press 3% Dosage is added to the sea cucumber compound feed, and the granulator is used to make 3 mm diameter particles. Experiments show that the weight gain rate increases by 0.8%; the blood cell phagocytosis rate increases by 59%; the production of superoxide anions increases. 45%; the heat stress survival rate increased by 5%; the bacterial challenge survival rate increased by 30%; after the feed was fed into the water for 12 hours according to the normal feeding amount, the ammonia nitrogen concentration in the experimental group was reduced by 15% compared with the control group.

Embodiment 3

[0018] 25 grams of astragalus, 25 grams of hawthorn, 20 grams of Radix Radix, 10 grams of angelica, and 20 grams of schisandra are mixed uniformly in a mixer in proportion (required coefficient of variation ≤ 5%) through ultrafine grinding (over 300 mesh), and then press 3% The dose is added to the sea cucumber compound feed, and the granulator is used to make 3 mm diameter particles. The experiment shows that the use of 20 large in the sea cucumber cultivation can increase the weight gain rate by 0.5%; the blood cell phagocytosis rate increases by 35.33%; the superoxide anion production increases 30%; the heat stress survival rate increased by 6%; the bacterial challenge survival rate increased by 10%; after the feed was put into the water for 12 hours according to the normal feeding amount, the ammonia nitrogen concentration in the experimental group was reduced by 10% compared with the control group.

Abstract

The present invention discloses a plant-type compound schlepper for stichopus japonicus. It is characterized by that its raw material composition includes (by wt%) 25%-35% of astragalus root, 20%-25% of crataegus fruit, 15%-20% of isatis root, 10%-20% of Chinese angelica root and 10%-20% of schisandra berry. The invented compound schlepper can be used as additive and can be added into the feed of stichopus japonicus for raising immunity of stichopus japonicus body, resistance to bacteria and heat resistance.

Description

technical field [0001] The invention belongs to the technical field of feed additives, and relates to a compound immune enhancer for plant-type sea cucumbers. technical background [0002] Sea cucumber is the most important aquaculture species in northern my country, and it is also the pillar industry of aquaculture in Dalian. In recent years, the excessive development and non-standard operation of sea cucumber farming have caused large-scale frequent outbreaks of sea cucumber epidemic diseases and the deterioration of the breeding water environment. Since there is no specific drug to treat the sea cucumber infection, prevention and treatment is particularly important. At present, a large number of antibiotics and chemical drugs are used for disease prevention in artificially cultured sea cucumbers. However, with the increase of drug resistance of pathogenic bacteria, the dosage of antibiotics and chemical drugs is also increasing, which makes the excessive amount of antibi...
