Distillers Grains are a cereal byproduct of the distillation process.I got a response to my email query from Blue Seal/Kent Nutrition Group...
So that's encouraging. now I just want to know more about these distiller grain shipments..
There are two main sources of these grains. The traditional sources were from brewers. More recently, ethanol plants are a growing source. It is created in distilleries by drying mash, and is subsequently sold for a variety of purposes, usually as fodder for livestock (especially ruminants). Corn based distillers grains from the ethanol industry are commonly sold as a high protein livestock feed that increases efficiency and lowers the risk of subacute acidosis in beef cattle.
