Is corn regularly fed to horses? Funny, mine have never had corn and I don't know a soul that feeds corn to horses.
All grains (and feed) rose in price due to the ethanol fraud. A dairy farmer told me tonight his feed corn went from $2 to $5 (Bu.) mostly from the ethanol fraud.
Dry C.O.B (Corn, Oats & Barley) is a reccomended basic horse feed. Wet COB has molasses added. You can buy all kinds of prepared fancy horse grains but the basic is COB.
