Introduction: DDGS is a concentrated feed in powder or in granularity which is produced through advanced technologies of centrifugation, vacuum suction filter, evaporation concentration, combination drying, granulation packing. Properties : Appearance: powder Colour: yellow or brown Nutrient component: Starch is converted into alcohol and CO2 and other nutrient component such as protein, fat, fiber etc all stay in the vinasse in the process of ethanol production from corn. Content of protein, B vitamins and amino acid is increased compared with those in corn because of function of microorganism. Moreover, it contains UGF in the process of fermentation. Main effects: It is used as raw materials for compound feed or feeding for animals. It has good palatability and can increase intake of protein, all kinds of amino acid, vitamin, microelement etc for feed animals. It contains bioactive substance and growth factor to stimulate digestive juice production of poultry, livestock and fish. It can restrain harmful bacterium in enteric canal to prevent disease and promote growth. It is the best substitute for bean pulp and other protein raw materials. Its protein sources is extracted from corn and it is a perfect raw materials for compound feed. Packing: In plastic woven bags of 40kgs Storage: Do not transport or store with poisonous, harmful and off-flavor substances. It should be stored at a ventilate and dry place.
