On Tuesday, Oct. 11 at 6:30 a.m., frost hung on the grass field surrounding Johanna Jalbert’s home near Isanti, Minnesota. Her baby cooed and the sun leaked light over the rural horizon as she pulled on her farm boots. It was time to milk the cows.

“Here, heifers! Here, heifers!” she yelled to a herd of dairy cows that were quietly meandering over the property. Nellie, a deep brown heifer with a white tuft of hair on her huge head, sauntered towards the shed — her milk-filled udder swaying as she stepped up to the milking stand.
