Cow comfort is an important aspect of any dairy operation. One part of cow comfort at Pagel’s Ponderosa in Kewaunee, Wis., is to provide cows with scratching posts. The dairy installed used street sweeper brushes in each of the dairy’s cow pens. There are four brushes in each pen and they spin on a pole. The cows use the brushes a lot, says dairy owner John Pagel.
