Best practices for liner transition
- Always monitor cow comfort and check for signs of teat discoloration during the transition.
- Allow several days for cows to adjust to the new liner, as the transition may not be immediate.
- Only adjust vacuum or pulsation settings after cows have fully transitioned to the new liner.
