Voluntary milking systems (robotic milking) allow cows to be milked at self-selected times, potentially improving welfare through increased autonomy, but require careful management to avoid welfare problems.
Robotic milking systems offer genuine welfare benefits through increased cow autonomy over timing and reduced crowding at milking times. However, poor transition management, inadequate fetch protocols and failure to act on early lameness or mastitis alerts can result in welfare deterioration. Technology is an enabler rather than a substitute for good stockmanship.
