Evaluating the piglet grimace scale

197

Animal Science master’s degree student Maria Lou and her Advisor Yuzhi Li are conducting research on the piglet grimace scale. The grimace scale identifies and assesses changes in facial expression when an animal is experiencing acute pain. This non-invasive method, along with the application of photogrammetry technology, provides a more detailed, 3D image of piglets. The goal of this project is to identify and recognize pain in pigs in order to help improve pain management and welfare.
