NFU, dairy forum, flooding, future foods

The World Dairy forum is meeting in Edinburgh. Dr Judith Bryans is the chief executive of Dairy UK. She says it's more important than ever to find new ways of adding value to milk, and that increasing exports is key to the dairy industry surviving. Meanwhile, business analyst Geoff Burch says dairy farmers need to find out their real cost of production - it's estimated that 60% of farmers don't know that figure. He thinks that attitude makes margins tight and extremely perilous.
