forfismum, I don't know what the ration of grain in to the process is compared to byproduct feed. I don't expect that much of what comes out after the ethanol has been extracted is wasted but I can see that there would be quite a bit of the energy gone from the feed.
It may be high quality in protiens, vitamins, or minerals, but there wouldn't be as much feed value as in what was used. The other thing to consider is that livestock producers, at least over here are stuck with low prices for the first time in years, all things being relative, compared to grain prices.l
