BOISE, Idaho (AP) — Faced with an increasing shortage of workers, Idaho dairies are investing in robotic milkers. John Paetz, regional manager of Lely North America, headquartered in Pella, Iowa, says “The interest in robotic milking in Idaho is growing quite rapidly.” The company has robots installed in three Idaho dairies now, with two more scheduled to come online in July and two more scheduled for later in the year or early next.

In robotic milking, the cow decides when she wants to be milked and goes to the robotic milker. While she enjoys a snack such as a high-energy pellet, a laser-controlled device finds her teats, cleans them and dries them, then attaches and milks. When she’s done, the robot detaches and the cow wanders off. All without human intervention.

Paetz says “Larger dairies, where they’re employing 20 people, can see a big benefit initially. We’re not in the business of displacing labor, but you can do the same job with less labor.” Idaho has been behind the curve in implementing robotic milking, partly because Lely, one of the major vendors, has been migrating its marketing across the country after starting in western Europe and then heading to Canada and the East Coast. “We just started looking at the western region in the last five or six years,” Paetz said. “We don’t want our infantry to outrun our lines of support.” Across the U.S., robots are now being used in 5 percent or fewer of the dairies, he said. “But it’s accelerating.”
