Immunopotentiator for large yellow croaker adults

Abstract

The invention discloses an immunopotentiator for large yellow croaker adults, which are prepared by uniformly mixing raw materials including fructooligosaccharides, mannan oligosaccharides, polysaccharide sulfates, yeast extract, vitamin C-2-phosphate and vitamin E-acetate. When added in feed in an amount of only 0.1 to 0.2 percent, the immunopotentiator can obviously improve the immunity and disease resistance in the large yellow croaker adults, so the survival rate of cultured large yellow croakers is improved by over 8 percent, and the immunoprotection rate is over 50 percent; and the immunopotentiator is free from toxic and side effects, residue and medicament resistance and avoids influencing the palatability of the feed. Therefore, with a small added amount, the immunopotentiator can obviously improve the immunity and disease resistance in the large yellow croaker adults, so that the culture survival rate is improved by over 8 percent and the immunoprotection rate is over 50 percent.

AI Technical Summary

Benefits of technology

The present invent describes a new type of nutrients called flavonoids that are found naturally occurring throughout nature (Flavones). These compounds have various benefits such as being able to fight off diseases caused by harmful bacteria or other microorganisms, reducing inflammations associated therewith, increasing body weight gain during pregnancy, prevention against cancer growths, promoting healthier fishes through antioxidant activity, protective collagen from UV ray damage, stimulating cellular metabolism, regulation of blood sugar levels, etc., making them useful ingredients used in food products like yogurt without causing any negative reactions over time.

Problems solved by technology

This patents discusses improving the growth performance or reducing harmful effects caused by various types of microorganisms that may cause illness on cultured fish during long periods of time. Current methods involve administering chemical agents like chloramine gas (C12) which kill off certain organism causing these symptoms. However, some researchers found that even low levels were associated with high mortality rates from tuna poisonings compared to healthier ones who had higher concentrated dosages. Therefore, finding new ways to enhance the defense mechanisms against pathogenic strains without affecting beneficial components within them could be useful for maintaining good food production efficiency while minimizing environmental impact.
