The grooving of our yard has made a huge difference to the confidence of our cows when approaching the platform. We have quite a steep flood wash yard and before the grooving the cows would hesitate as the surface was too "Glassy" and slippery.
Cows would often slip over.
These days are over and i can certainly recommend grooving to anyone else who has a slippery surface problem.
