A photo from the 2023 World Dairy Expo. World Dairy Expo, through Oct. 4, Alliant Energy Center: If you’ve never been to the World Dairy Expo, it’s definitely worth attending at least once, and Thursday is your last chance. The exhibits will be more beneficial if you are a dairy farmer, but if you want to understand that dairy farming is both a science and a business, this is a good way to do it. Prize dairy cows in an array of breeds (Ayrshires, Jersey, Brown Swiss, Guernsey, Holstein) are shown like beauty queens in the center ring of the Coliseum. The Purple Cow gift shop features cow-themed clothes, art, and other doodads. And don’t miss the food concessions, with UW-Madison ag school’s specialty grilled cheese stand (also serving chocolate shakes) always a favorite. Find the schedule and tickets at worlddairyexpo.com.
