Good fencing - electric preferably! Hilary's right about Andy Case, but it's the best book of its kind by far - the others are gathering dust on our bookshelves. Give the pigs enough food to keep them occupied for 20 minutes twice a day and you can't go far wrong - along with the occasional veggie snack! Find someone nearby who has been keeping pigs for years (try looking up the various breed societies' websites), make friends - their experience will be invaluable. And maintain a sense of humour at all time. Good luck!
