Identifying when animals are in pain is good for moral reasons, of course, but also for maximizing their productivity.
Detecting pain in animals isn’t exactly as easy as asking them how they’re feeling; they can’t talk, after all. There are ways of identifying signs of pain, however—animals may vocalize pain through unpleasant shrieks, or may not eat as much as expected. Measuring whether they’re in pain isn’t always straightforward though, and can be subjective, requiring decades of experience to make a judgement call about whether an animal is in distress.
Scientists believe the same idea can be applied to recognizing pain in the faces of animals. Decades of experience from veterinarians identifying pained faces could be ingested by AI algorithms to automate this process for farmers. The technology could eventually be applied to other non-verbal patients, particularly young children.this week on the work coming out of the University of Florida’s College of Veterinary Medicine.
“It’s not just an animal-welfare issue,” said Ludovica Chiavaccini, a clinical associate professor of anesthesiology at the University of Florida’s College of Veterinary Medicine. “We also know animals that are in pain don’t gain weight and are less productive.
