VIPPEROD, Denmark — European scientists have developed an artificial intelligence algorithm capable of interpreting pig sounds, aiming to create a tool that can help farmers improve animal welfare. The algorithm could potentially alert farmers to negative emotions in pigs, thereby improving their well-being, according to Elodie Mandel-Briefer, a behavioral biologist at University of Copenhagen who is co-leading the study. The scientists, from universities in Denmark, Germany, Switzerland, France, Norway and the Czech Republic, used thousands of recorded pig sounds in different scenarios, including play, isolation and competition for food, to find that grunts, oinks, and squeals reveal positive or negative emotions.more
