Feed prices go up whenever corn prices go up, as most feeds have corn as their main ingredient. In 2010, feed prices tripled and I had to double my goat milk prices just to break even. My cheese makers (who I sold my milk to) couldn't afford my milk at double the price and they stopped making goat cheese, putting my goat milk operation out of business. I was part of a 75 farm, goat and sheep milk cooperative. 74 out of the 75 farms stopped producing goat and sheep milk in 2010.
Part of the problem is that corn is used for so many other things other than feed, such as methanol for gas. I don't know what the solution is, but it's a bad situation. Dairy farms (cow, goat and sheep) in my area are going out of business at an alarming rate because of this, and this has been going on for over 10 years.
