ADM mills our custom pellet that is 20 percent, and the cost varies from 450 to 650 depending on the commodities market. We like what they have done for us and they will alter the formula on a moments notice. Add a little garlic, add a little vanilla for taste, increase the fat or whatever. No questions asked, and a fairly quick turnaround time. We buy bulk and a minimum order for us is three tons. At times we get a load that has more fines than I would like, but I have tried most of the major companies and they all put out a bad load from time to time.
