Automatic milking systems change dairy cow behavior and welfare in ways that require specific management attention.
Automatic milking systems give cows control over milking frequency that motivated animals use well. However, low-ranking or lame cows may not visit the robot adequately, causing udder engorgement, mastitis, and welfare decline. Robot fetching programs that identify cows with insufficient visits and bring them to the robot prevent these problems. Lameness reduces robot visitation creating a welfare cycle requiring proactive monitoring.
