Abstract: Provided is a method for producing hen's egg improved in quality includes feeding a solid-cultured product of filamentous fungi blended with feedstuff of a hen or the solid-cultured product of the filamentous fungi alone to a hen to improve quality of the hen's egg, in which at least one quality among improvement in yolk color, improvement in eggshell strength, increase in an egg white height, increase in an eggshell thickness, increase in an egg weight, increase in a Haugh unit, increase in an egg production ratio, and reduction in a generation ratio of an abnormal egg is improved for hen's egg that the hen ingesting the solid-cultured product of the filamentous fungi produce.
