Astronaut A4 Grazing

For dairy farmers using grazing-based systems, how do you balance pasture management and cow nutrition while integrating robotic milking systems like the Lely Astronaut? Have any of you experienced challenges similar to those cited in the Lely A4 class-action lawsuit, and how have you adapted your grazing or robotic milking practices to maintain milk production and cow health?

  • We run Lely Astronauts on pasture too, and yeah, it’s a bit of a balancing act. The biggest thing is getting cows to the robot often enough. We keep paddocks close — no more than about 500 m from the robot — and use a Grazeway gate so cows have to walk past the robot to get back out. We feed a good hit of concentrate in the robot. That’s what keeps them coming in, even when the grass is sweet. If visits start dropping, we tweak the feed or open a fresh strip of grass a little later so they have a reason to come up. As for the A4 problems — yeah, we had some headaches early on. Pinch sleeves wore out faster than we liked, a few missed quarter attachments, and SCC crept up. We learned to keep spare sleeves on the shelf and swap them before they fail. We also stay on top of maintenance — vacuum checks, teat cup alignment, all of it — and we watch the Horizon data like a hawk. If we see cows skipping visits or a sudden SCC jump, we act quick. Bottom line: the robots work fine with grazing, but you have to manage traffic, feed, and maintenance every day. Don’t just “set and forget” — treat it like another herd chore. Since we tightened up those routines, milk yield’s been steady and cows are healthy.
