Product Name: Vitamin C Immunopolysaccharide Develop Immunity From Disease Type: Vitamin Function: Vitamin Additives Shape: Powder Certification: ISO Trademark: Tianyuan Transport Package: 500g /Bag*20/Bucket Specification: 500g /bag Origin: Hebei China HS Code: 2309901000 Product Description Immunopolysaccharides can activate T lymphocyte to release cytokines and bind to B lymphocyte and macrophage receptors, make B lymphocyte differentiate and increase to form antibodies, and promote macrophage phagocytosis. At the same time, special proteins were produced in differentiated and incremental B lymphocytes, which significantly enhanced the immunity of aquatic animals.Main ingredients:dextran, mannan oligosaccharide, fructooligosaccharide, lipopolysaccharide, alkaloids, active polypeptide.Appearance odor: Light yellow or yellow brown powder, with yeast-specific fragrance.The main functions of immune polysaccharides are as follows:1. Enhance the immune function of aquatic animals and enhance their resistance to pathogenic microorganisms such as bacteria, viruses and protozoa.2. It can protect the liver of aquatic animals and enhance the ability of detoxification and nutritional transformation of the liver.3. To regulate the intestinal micro-ecological environment, improve the body's disease resistance, emergency response function, high temperature resistance and low temperature resistance.4. Promote the growth of bifidobacteria in the intestinal tract of aquatic animals, thereby promoting growth and weight gain.5. Value-added anaerobic beneficial bacteria can improve water quality and stabilize PH value.Usage and dosage: It is widely used in freshwater and marine aquaculture, such as fish, shrimp, crab, shellfish, turtle, eel, sea cucumber, abalone and turtle.1. Nursery seedlings: After seawater immersion, add to the bait, mix and feed. When sea cucumber, scallop and other seafood are industrialized seedlings, 1.0-1.5g is added to each cubic water body, and the amount used in vivo transportation is increased to 100-200 G.2. Adult culture: feed in fish and shrimp feed evenly. Routine dosage was 0.1%, stress dosage was 0.15-0.25%, and morbidity dosage was 0.3-0.4%. It is directly mixed with feed.Notes: Use it as soon as possible after opening, seal the packing bag after using, and pay attention to moisture-proof.
