PICKETT, Wis. (AP) — Each of the 9,000 cows at Rosendale Dairy has a microchip. Workers can scan the cows’ ears with smartphones for real-time information on nutrition, health history and productivity. Feed is calibrated to deliver a precise diet. Machines handle the milking. An unmanned-aerial vehicle gathers data from nearby farm fields. That data is then analyzed to improve the yields of crops grown for feed. Technology has long played an important role in agriculture. But it has become critical with dairy farmers seeking every possible efficiency.
