A feed for domestic fowls which comprises an indigestible dextrin prepared by roasting a starch in the presence of a mineral acid to give a pyrodextrin and treating the pyrodextrin with alpha -amylase or an indigestible dextrin prepared by further treating the alpha -amylase-treated product with glucoamylase, followed by filtration, purification and separation and removal of digestible fractions of the product through chromatography using an ion exchange resin. The feed serves to inhibit the formation of fatty liver, to improve the meat quality and the rate of egg laying, to improve the eggshell strength and to reduce the cholesterol content in the egg. |
