I accept the concerns that have been raised, but I am reluctant to pass judgment on farmers who are delivering high standards of animal health and welfare in some intensive farming systems, including those involving continuously housed dairy cows. We need to get the results of the study we are undertaking with our Scottish partners, so that we can understand the impact of the trend on the health of animals. Intuitively, I agree with the hon. Gentleman, but we need some evidence before we perhaps bring about regulatory changes that might impact on an industry already wrestling with difficult challenges.
