SPENT GRAIN BASED ANIMAL FEED MATERIAL AND A METHOD FOR ITS PRODUCTION

摘要

A process for the preparation of animal feed material comprises the treatment of spent grains containing water- insoluble carbohydrate with one or more carbohydrate lyase enzymes to increase the content of available carbohydrate therein, said grains containing or being subsequently contacted with lactic acid producing microorganisms. An animal feed material may comprise spent grains having an overall dry-matter content of 23-30% by weight and containing at least one carbohydrate lyase enzyme.
