FOND DU LAC, Wis. (AP) — Developers say construction of a dairy operation that could eventually milk 9,000 goats a day should begin in a couple months in Calumet County. Drumlin Dairy is buying 35 acres in Brothertown, just northeast of Fond du Lac. One of Drumlin’s owners, Kenn Buelow, says Wisconsin has the country’s most milk goats, with 44,000, but more are needed to meet the needs of goat cheese makers. Drumlin’s operation near the eastern shore of Lake Winnebago is near the state’s largest cow dairy operation, owned by Milk Source. That company also milks about 700 goats. Brothertown has its own zoning laws, so Drumlin won’t need a conditional use permit.
