True dat, TB.
Local ethanol plant here removes most of the oil from their product, as they sell ethanol, corn oil, C02, and distiller's grain products & 'syrup'.
Have a friend about a mile up the road who's got a small (~300 hd) calf feedlot... he buys his DDG from a plant 85 miles away, that doesn't take out the oil... he says performance is enough better that it's worth paying the freight... but he's buying it by the semi-load, whereas we're buying 3 tons or so every couple of weeks, and don't have a place to store or feed out a semi load at a time.
