On this week's livestock special edition of Countryfile, Adam is on his farm in the Cotwolds looking back through the archives at some of the team's favourite encounters with farm animals big and small. In County Durham, Matt Baker is being helped by the whole family at lambing time. Julia Bradbury is in North Kent meeting the goats as they make their regular visit to the dentist. Ellie Harrison is in Lincolnshire finding out about the county's proud tradition of pork production and Jules Hudson is in Hampshire with some rather large buffalo who make rather delicious cheese. Meanwhile, on his own farm, it's time for the first of Adam's lambs to be weaned from their mothers and sent to market, his White Park cattle need protecting against flies and his donkeys and goats get a pedicure.
