DDGS - Nutritional Value for Poultry

摘要

No other grain has been developed and used to produce so many other co-products than has occurred with corn (Corn tech book). Com can be processed to concentrate starch and sugars, oils, and protein for human or animal consumption. As a result there is a large variety of corn co-products are available for use as ingredients in animal feeds depending on the type of milling process used. The wet milling process is used primarily for the production of starch and will produce four different feed ingredients - condensed corn fermented extractives (corn steep liquor), corn germ meal, corn gluten feed (wet or dried), and corn gluten meal. Corn gluten meal will be used primarily for protein and as a source of xanthophylls for providing pigmentation in poultry carcasses and egg yolks. Dry milling is used for production of ethanol after fermentation of the com or other grains. The two co-products produced are corn distillers condensed solubles (liquid), distillers grains (wet or dry) or dried distillers grains with solubles.
