Pigs are highly sociable creatures and prosper when living in small, stable groups. They thrive on contact with each other and have a complex language of grunts and squeaks, which scientists say they can interpret. Scientists have even detected regional variations in pigs’ grunts. They sleep together huddled in nests and greet other pigs by rubbing noses much in the way we would shake hands. Pigs are highly co-operative in social groups and show affection by grooming each other. Pigs are the most intelligent of farm animals, and tests have been carried out that prove that pigs can be trained to do more than dogs.
