Embodiment 1

[0021] A kind of chitosan oligosaccharide parenteral bait for improving the immunity of sturgeons comprises a base material and an auxiliary material, the auxiliary material is chitosan oligosaccharide, and the addition amount of the auxiliary material is 1% of the weight of the base material. The adding method of the chitosan oligosaccharide is dry powder.

[0022] The base material is made of puffed feed for broodstock sturgeon, compound feed for adult eels, fish oil, cotton meal powder, plant leaves, soybean lecithin and microbial fermentation culture. The parts by weight are as follows: 30 parts of extruded feed for broodstock sturgeon, 15 parts of compound feed for adult eel, 3 parts of fish oil, 3 parts of cotton meal powder, 2 parts of bamboo leaves, 4 parts of soybean lecithin and microbial fermentation culture 15 servings.

[0023] The microbial fermentation culture is prepared by mixing the basic culture medium with a complex microbial liquid in a weight ratio of 3:...

Abstract

The invention relates to chitosan-oligosaccharide parent fish bait capable of improving immunity of sturgeons. The chitosan-oligosaccharide parent fish bait capable of improving immunity of sturgeonscomprises a base material and an auxiliary material, wherein the auxiliary material is chitosan oligosaccharides; and the addition amount of the auxiliary material accounts for 1-1.5% of the weight ofthe base material. By using a chitosan oligosaccharide solution or a chitosan oligosaccharide feed in fish culture, influence on early-stage immunity of the aquaculture species is achieved within a short period of time; moreover, the chitosan oligosaccharide solution or the chitosan oligosaccharide feed is also capable of effectively up-regulating concentration and activity of immune related proteins, as well as improving bacteriostatic and bactericidal abilities so as to enhance tolerance to concentration of pathogens in the environment. For fishes, bacteriostatic and bactericidal functionsof nonspecific immunity play important roles in the immune system, and thus, disease resistance of fishes can be effectively improved by enhancing the bacteriostatic and bactericidal functions; and the chitosan oligosaccharides, as very small molecules, are capable of effectively preserving characteristics of primitive substances when passing through the digestive tract, and thus, the primitive substances rapidly enter body of organisms, and directly act on cell levels so as to participate in various life activities of fishes.

Description

technical field [0001] The invention belongs to the field of aquaculture, and particularly relates to a method of adding chitosan oligosaccharides as an immune additive to feed to improve animal growth performance, regulate animal intestinal microorganisms, improve animal immune function, replace part of antibiotics and reduce drug residues. Chitooligosaccharide parent fish bait for fish immunity and its preparation method. Background technique [0002] In the past ten years, my country's fish aquaculture industry has achieved rapid development, and the aquaculture output has increased year by year, with high economic benefits. my country has also become the world's largest breeding country. However, a variety of reasons for the frequent occurrence of farmed fish diseases. It is impossible to alleviate the serious disease situation of fish quickly by improving the disease resistance mechanism of fish itself. Studies have found that there are various immune regulatory fact...
