The feed additive is added into feed according to a weight percent of 3-8% for laying hen feeding; when the laying hens are compared with laying hens which are fed with feed without the feed additive of the invention, results show that after feeding for half a month, yolks of the laid eggs become red, and are bigger, and the egg white is viscous, and has obviously different taste; after feeding for one month, yolks of the laid eggs become redder and bigger, and the egg white is more viscous, and has better taste.
