New research suggests that pigs — like many humans — are smart enough to recognize a conflict between others and defuse the situation.
, the hoofed mammals appear to have the cognitive ability to watch and empathize when two other pigs fight — and then intervene afterward to reduce the levels of aggression or anxiety — a form of social regulation that can benefit the wider group.
When a victim is contacted after a fight, its anxiety levels drop, while aggressors that are approached are less likely to attack the victim — or other members of the group — again. The Italian researchers spent six months in 2018 observing 104 pigs on a farm near Turin, in northern Italy. The pigs were free to forage throughout a 13-hectare woodland area — an environment that let them move and behave naturally. Researchers collected hours of video data to analyze.
“The nose is very important for pigs, not just for communication and exploration, but for social interaction,” Cordoni said.
