Wisconsin Cows Weather Heat Wave

7/25/11 – Moderating temperatures are good news for Wisconsin dairy farmers. Dairy cows prefer cooler temperatures. When temperatures top the 90s, as they did this past week, dairy cows don’t produce as much milk. The intense heat can also make cows susceptible to bacterial infections. No deaths of dairy cows have been tied to the heat wave, though some livestock farmers have reported losses to the USDA.
