Illinois officials are hosting visitors from nearly 20 countries which are potential milk buyers. Representatives from the Dominican Republic, Ecuador, Mexico, Nepal and Thailand are among those participating in this year's Illinois Dairy Tour. The event began Monday at Rolling Lawns Farms in Greenville. It was there that in 1915 one of the state's first Holstein cows was registered. Warren Goetsch is acting director of the Department of Agriculture. He says Illinois is 22nd in the nation in producing milk, and the Dairy Tour is a key part of the state's marketing plan. The tour will also stop at Trouw Nutrition USA in Highland, the University of Illinois Dairy Research Facility in Urbana, GEA in Naperville and the Chicago Mercantile Exchange.
