around here alot of cattlemen feed 1/2 corn stalk bales, 1/2 poor hay, and #4 per head of distillers for a cattle maintainance ration, with a high cal mineral. I have heard that when used in a finishing diet it reduces the marbeling? Good feed for a good price. Keeps for at least a month in the cold. Summer you'll want to tarp it or the sun and heat causes it to mold in about 2 weeks. Start them slow or don't stand behind them when they cough!
