Secret Life of Farm Animals: Pigs

SINOPSE

It's harvest season. We follow a litter of piglets from birth as they grow up in the Brecon Beacons. We test the theory that every piglet always returns to the same teat to suckle, show that pigs love mud to keep cool because they have practically no sweat glands and we show how intelligent they are with a series of puzzles. We also reveal that they are masters at the art of deception.
