As September’s National Honey Month ends tomorrow, Wisconsin — the land of milk — hosts the opening of the World Dairy Expo, running through Saturday. The exposition in Madison is expected to draw about 77,000 attendees. Farmers, producers and visitors will see some of the best dairy cattle, learn about genetics, profit margins, and even cow comfort — while mingling with some thousands of dairy men and women from dozens of different countries. America’s dairy product manufacturing employs about 130,000 people in over 1,600 establishments. The annual value of all this milk, cheese, butter and more is nearly $112 billion.
