Hours earlier, the farm's owner and his brother, both Amish, worked methodically from cow to cow, scraping off the dirt and loose black and white hairs from the Holsteins with a curry comb. They dipped brushes into a bucket of coat shine and slathered it on the cows in anticipation of the crowds to come. Each cow had a numbered sticker slapped onto her backside that corresponded with a resumé of sorts, details about her lineage and the percentage of butterfat she made, and when her calves were due.
