We cannot figure the cost of production into BOTH ethanol and feed.

Starches are feed as well. It may not be the most needed component, but to remove it from the feed would require something to replace the caloric input. (I think)

[Mr. Lucky]

Some of the caloric value of corn is used for heat, the need for which can be controlled by herd management. Most of the caloric value of corn, especially for ruminants, is left in the feed lot. In the good old days, we let our hogs "follow" our cattle and our chickens "follow" or hogs. Contract buyers kinda frown on that nowadays.

But most of the protein value of raw corn is also wasted (it's simply not digested). DDG's or gluten meal is much more efficiently digested, so the distillation process actually increases the efficiency of the corn.
