The Countryfile team visits the rural county of Wiltshire. Matt Baker looks at the pig industry. The county has a long and proud history with the animal, and Matt visits a farm containing the oldest pedigree herd of pigs in the country. They are Tamworths, and Matt helps out with the piglets who are just a few days old. He also sees how the meat from the pigs is cured and smoked. Jules Hudson is at one of Help for Heroes' recovery centres at Tedworth House, meeting some of the servicemen who have suffered life-changing injuries or illnesses whilst serving their country. He sees how working in the countryside helps in their recovery and also helps set them up with skills for a career outside the forces. Julia Bradbury is in Cambridgeshire looking at the birds that call the UK home in the winter months. She heads to Ely with urban birder David Lindo to see what they can find in the city, before heading to Welney Wetland Centre to feed the swans who have made the long journey from colder climes. With huge swathes of our countryside under water, Tom Heap asks whether rural areas are being sacrificed so our towns and cities can keep dry. Down on the farm, Adam finds out about a parasite that is affecting cattle, including some of his own.
