Abstract

The invention relates to a method for preparing an immunostimulant for fish, which belongs to the technical field of aquatic formula feeds. The method is characterized in that the method comprises the steps of taking rhubarb extract, humifuse euphorbia herb, hairyvein agrimonia herb and bud, red-knees herb, glutamine, potassium dihydrogen phosphate and the like, as well as a carrier; fully mixing all components, then smashing and preparing into dry powder. The method has the advantages of stable sources of raw materials, simple preparation, extensive material obtainment and low cost; the immunostimulant is prepared from the fish immunization mechanical and can not only supplement Chinese herbal medicine, but also supplement western medicine of glutamine dipeptide; and the immunostimulant conditions stress of the fish through the combination of Chinese and western medicines and appropriately supplements the loss of Na+, K+ caused by the stress for controlling the stress of the fish. When in use, the immunostimulant can improve the fish immune and the antioxidant capacity, improve the high density resistance of the fish and the resistance to aeromonase hydrophila infection and promote the growth of the fish.

Description

technical field [0001] The invention relates to a preparation method of an immune enhancer for fish, belonging to the technical field of aquatic compound feed. Background technique [0002] In recent years, with the rapid development of my country's aquaculture industry, the disease problem of aquaculture has become more and more serious. Common diseases are still very common, new diseases continue to occur, the diagnosis and monitoring technology is lacking, the ecological environment of aquaculture waters has deteriorated seriously, and drug abuse The problems are prominent, and the hidden dangers of aquatic product quality and safety are prominent. According to statistics, diseases of aquaculture species occur frequently. The annual incidence of aquaculture diseases in the country is over 50%, and the loss rate is about 20%. Direct economic losses caused by aquaculture diseases every year It reached tens of billions of dollars. In order to prevent and control pathogens, th...
