Natural materials derived from yeast cell wall and its use as an immunity enhancer

摘要

The present invention relates to a novel use of glucan and mannoprotein isolated from a yeast cell wall as an animal enhancer for enhancing an immune function of an animal by feeding the glucan and mannoprotein isolated from a yeast cell wall to an animal feed and destroying the cell wall of yeast, The effect of the yeast preparation on the growth ability of mice and rats was investigated by measuring the weight gain, daily gain, feed intake and feed efficiency while feeding the yeast preparations separated and isolated from the rats, As a result of measuring the activity of natural killer cells in the spleen cells after the spleen was collected from the rats fed with the preparation, mannoprotein and glucan isolated from the cell wall of the yeast activated the animal's immune system, It has an effect of improving resistance.
