We installed CowKühlerZ™ over the freestalls of one of our high groups in the summer 2013. The high group directly across the feed aisle had no cooling over the freestalls. Both pens had bunkline soakers. We observed that the pen with CowKühlerZ™ over the stalls had stronger feed intake consistently throughout the summer and during several heat events. You could see the difference each morning with more feed disappearance compared to the pen directly across the aisle.
