Letting Cows Set Their Own Milking Schedule

MADISON Wis. - For generations, Wisconsin's family dairy farmers have milked their cows twice a day on a strict schedule. But it appears when cows can give milk when they want to instead of when farmers decide to, they're happier and healthier. Voluntary robotic milking systems are popping up at farms in Iowa, especially in smaller operations such as Blue Knoll farms in Wilton where Laura Jones is dairy manager. She said the cows can walk right in and be milked by a robot when they feel the need.

"It kind of just looks like an elbow," she said. "It bends at the center, just like our elbows. It's a little camera laser screen that finds each one and that's how it gets the milking accomplished."

She said smaller dairy farms, such as Blue Knoll, which has about 50 cows, are ideal for voluntary robotic systems, but larger operations have been installing them, too. Wisconsin is home to more family dairy farms than any other state.

Jones said the systems also are convenient for farmers because they require far less labor, and their cows are happier.

"It reduces their stress," she added. "Even this summer, I've noticed their heat stress isn't as bad as it has been in the previous years. They just don't seem as hot."

She said after about three months, most cows learn to manage the robotic milkers on their own.

The high-tech system also helps detect diseases such as mastitis, an inflammation of the udder, the most common disease in dairy cattle. Jones said the robotic milkers do it by recording the cows' vital signs.

"I can tell if they get sick because they'll drop lower than average and it records every milking, how much grain they eat, anything you can really even imagine how much it's recording," she said.
