“C’mon girls. C’mon,” Mike Vieira calls out his evening invitation to the ladies in black and white at Spokane’s Family Farm. “C’mon,” he repeats, walking into the pasture, “C’mon. Let’s go.” Visitors make the “girls” hesitate slightly, but they eventually oblige and line up behind the barn door for the evening milking. It’s a ritual repeated twice daily at the farm 13 miles west of Spokane where Mike and Trish Vieira bottle up to 2,000 gallons of milk each week. “This is what everyone thinks of when they think of a dairy,” Mike Vieira says. The couple began milking cows a little over a month ago, after spending the winter retrofitting the 100-year-old barn with modern milking and pasteurizing equipment and preparing for the arrival of the Holstein cows. It’s a small operation, with just 30 animals in a state where the average dairy had 480 cows in 2007. Many of the state’s large dairy operations have more than 2,000 animals.
