Sound's funny, but it works!
Back in the early 80's I was raising cattle for a high school FFA project and get money to start college. About 40 miles away we had an alcohol plant that made alcohol for gasohol. They sold the grain after it hand been used in the alcohol process for feed. It still had some alcohol content and the cows loved it.
That all stopped when the plant got a load of seed corn by accident. The chemical on the out side of the corn produced something in the milk that caused cancer in people. A lot of dairy farms were feeding the grain. The plant had to stop selling the grain all together.
