FEED FOR EGG-LAYING HEN CAPABLE OF INCREASING THE CONTENT OF AN IMMUNOPROTEIN AND METHOD FOR EGGS CONTAINING A LARGE AMOUNT OF IMMUNOPROTEINS USING THE SAME

摘要

PURPOSE: A feed for an egg-laying hen capable of increasing the content of an immunoprotein and a method for eggs containing a large amount of immunoproteins using the same feed are provided, thereby effectively producing the eggs containing a large amount of IgY immunoproteins. CONSTITUTION: The feed for an egg-laying hen contains 0.3 to 0.5 wt.% of cinnamon and 2 to 4 wt.% of peppermint. The eggs containing a large amount of immunoproteins are produced by feeding the feed containing cinnamon and peppermint to with administration of a Streptococcus mutans strain into an egg-laying hen, in which the cinnamon is added in the amount of 0.1 to 2 wt.%; and the peppermint is added in the amount of 0.5 to 4 wt.%. When an egg-laying hen is fed with the feed containing cinnamon and peppermint along with administration of a Streptococcus mutans strain, an egg contains a larger amount of IgY immunoproteins than that of the prior egg-laying hen.
