Depends on what the grain is: field corn, field peas, feed barley, wheat, etc. If you're just referring to the word "grain" there really is no special name for such grain that is fed to livestock like cattle...just "grain."
Grain.
It was around the 1950's that feeding grain to cattle became popular. Prior to post war times no one had heard of 'grain feed cattle'. They were all raised on pastures. After the war a higher consumer demand forced farmers to find a way to fatten their cattle faster to get them ready for market. Pasture raised cattle take as long as three years to get ready for market. Grain fed cattle takes as little time as fifteen months.

No. If grass-fed cattle got any grain, they wouldn't be grass-fed then. Grass-fed beef comes from cattle that are finished on grass only, with absolutely NO grain.

Corn, barley, oats, etc., same grain fed to cattle.
Why not? It's a cheaper source of feed for cattle than grain itself. All distillers grain is the left over stuff that was not needed after the grain was distilled. It's a good source of feed for cattle.

Finisher cattle are range-raised, i.e. - grass fed, yearling or older beef cattle that are ready to be "finished" on grain to increase marbling prior to slaughter.
