The modern, fuel ethanol industry is growing at an explosive rate in the USA. This growth is resulting in a concomitant increase in availability of “new” Dried Distillers Grains with Solubles (DDG/S). Even though many industrial applications are being pursued, for the foreseeable future, this product will be fed to animals. This “new DDG/S” is quite different than product described by “old book values.” It is high in available energy, available amino acids (AA’s), and available phosphorus (P). Further, feeding trials support fairly high inclusion rates in virtually all production animal species. Despite the advances in new technology, consumers are cautioned that even the product can be highly variable in nutrient profile and quality. Further, new technologies, unheard of just a few months ago, are rapidly being implemented which will change the nutrient profile of DDG/S and will introduce other, new ingredients. One must take care to know exactly what product is being purchased and limitations for its use.
