Jimmy Doherty's Farming Heroes - Wales

Five years ago, Jimmy Doherty gave up life in the city to start his own farm. Now he wants to see what other farmers are achieving. As the world food crisis grows, what happens to farming will affect us all. So in this new series, Jimmy travels the country to meet the people shaping the future of British farming. From hi-tech agri-business, to organics, to remote family farms, he's on the search for those striking out in new and original ways. This week he's in Wales where farmers have turned farming on its head. They use daffodils to tackle Alzheimer's, garlic to combat the deadly side effects of cows and Kiwi science to create super sheep.
