1results about How to "Enhance cellular immunity" patented technology

This invention relates to the application of microalgae polysaccharides in enhancing intestinal immunity in dairy cows, belonging to the field of feed technology. The microalgae polysaccharides prepared by this invention are used to increase the secretion of IgA, IgG, and IgM by the intestinal mucosa. This invention uses a specific ratio of kelp buds, Dunaliella salina, and Haematococcus pluvialis for pre-enzymatic hydrolysis using trypsin and nattokinase for a certain period of time, followed by enzymatic hydrolysis using hemicellulase and pectinase for a certain period of time. The resulting microalgae polysaccharide product has excellent effects in promoting the secretion of immunoglobulins in the dairy cow intestine, significantly increasing the content of IgA, IgG, and IgM in the dairy cow intestine, thereby enhancing intestinal immunity. It can serve as a highly effective alternative component for improving the intestinal immune function of dairy cows.
