I was under the impression that GA Wright was an experienced dairy farmer, but he says he never really worked on a farm ("Understanding farm life", Mailbox, August 25). Mr Wright admits he doesn't "understand the current trend" and accuses me of using "second-hand information".

My information may be second-hand, but it is from reliable sources including Defra, Compassion in World Farming (CIWF), veterinary scientists, and up-to-date reports. Anyone wishing further information on dairy farming should visit the website at:
