Abstract: The present invention relates to a process for the preparation of a "self-degrading" composition suitable for use in feeding and/or feed-conversing purposes and if desired for the conversion thereof into a self-degrading fodder mixture which comprises pre-degrading the starch being present in cereal fodder and/or maize fodder to an extent that the degradation index of the crop should be from 0.12 to 0.27, and thereafter admixing the so-called "available starch" thus obtained in finely ground form in optional order of succession with .alpha.-amylase and optionally with further additives and--if "self-degrading" fodder mixture is to be prepared--with fodder.The composition of the present invention provides carbohydrates utilizable by the digestive organs of animals. The process of the invention provides products equivalent with the very expensive maltodextrins using cheap and readily available starting materials.
