They took turns minding each other’s piglets so that each sow could forage. All of this natural behavior is inexpressible in confinement.
Domestics pigs, usually raised in confinement, were let loose in this facility and their behavior observed.
In this environment, the sows covered almost a mile a day in foraging, and, in keeping with their reputation as clean animals, they built carefully constructed nests on a hillside so that urine and feces ran downhill.
Under normal conditions, pigs reveal that they are highly intelligent and behaviorally complex animals.
Researchers at the University of Edinburgh created a ‘pig park’ that approximates the habits of wild swine.
