Mark Wagner Wagner Dairies Middleton, Wisconsin Chatting with Mark Wagner or Wagner Dairy in Middleton, Wisconsin. This is one conversation I could have again. Mark has some interesting and innovative ideas that he brings to agriculture and dairy farming in general. He tells us about new milking machines that give a gentler massage on the animals as well as being more effective and efficient making the entire process easier on the cows. Mark told me about his interest in using brush waste and water waste from cities to compost in his fields, a new corn for the US dairy industry that obtains more easily digestible starches for cows, and how he uses O3, a free radical, in the cooling and shipping process so that his milk is never exposed to oxygen until bottling.
