We can now decode pigs’ emotions. Using thousands of acoustic recordings gathered throughout the lives of pigs, from their births to deaths, an international team of researchers is the first in the world to translate pig grunts into actual emotions across an extended number of conditions and life stages. The research is led by the University of Copenhagen, the ETH Zurich and the France’s National Research Institute for Agriculture, Food and Environment (INRAE), and can be used to improve animal welfare in the future.
