What is distiller's corn? How is it different than whole corn?

Question

Some people were talking this weekend about feeding distiller's corn. What nutritional difference is there compared to whole corn?

Thanks!

Answer 1

It differs from whole corn in much of the starch has been converted into alcohol so is missing from distillers grain. It still makes a good feed but is not nearly the quality of whole corn.

Answer 2

Distiller's corn is the spent corn from the fermentation process of making whiskey.   It is not alcoholic. It is easier for a horse to digest since the sour mash process breaks down nutrients.

Years ago FALSTAFF Brewery, marketed their spent brewers grains in horse feeds.  Have no idea if they still are.

Answer 3

Distillers grains are the residue after conversion of the starch in the grain to alcohol which is subsequently distilled and collected.  This residue is much higher in protein 26-28% as compared to the original grain.  Corn starts at about 9% dry Matter basis.

the bulk of the starches and sugars have been removed.  The mineral content and the Fiber content have also been concentrated in the residue.  

As a protein supplement it is far superior to corn but as an energy feed it is deficient.

Answer 4

It is what's left of the corn after it has been used to produce booze or ethanol to put in gas to make E85.  The cattle thrive on it, but stay upwind of it.

Answer 5

derno im sorry i need points spam me or something lol but dont report me!!!!!

Answer 6

DDGS- (Distiller Dried Grain with Soluble) is another term for this product... roughly 1 bushel of yellow corn will produce 18 lbs of DDGS. It is a common bi product coming from the  production of Ethanol.  Its a great feed that cattle farms are beginning to use.  Its cheap and readily available.

Answer 7

What the other guys said is pretty much true except for the part about not being as good as whole corn for feed.  That depends upon what you need the feed for.  After the yeast has done it's job of converting starch to alcohol, the DDG (dried distillers grain) is about 10% starch and 15% protein (whole corn is 60-65% starch and 5-7% protein).  Being low in starch, it's a good source of protein to feed to ruminants of forage diets.  The low starch doesn't mess up the rumen pH and the microbes responsible for ustilizing forages.
