That's going to be hard to do. Feedstuff prices respond to the laws of supply and demand very nicely.
That's how the National Cheap Food Policy became to be so successful. The USDA carefully crafted programs to stimulate large crops, which drove down food prices due to large supplies. However, they were careful not to generate such large crops as to drive too many farmers out of business in one crop cycle. As a result, farmers have been held captive for decades. And we've had cheap food.
With the advent of ethonal, farmers are now more free of the USDA farm programs. It is going to cost a lot of money to get the farmers to cooperate with the USDA again. That, or huge over production, always a problem for farmers.
