A new approach to teaching welfare assessment is described and has been used with two cohorts of first-year veterinary undergraduates (totaling 515 students). The welfare assessment protocol was devised and trialed using pigs as an exemplar, but its principles are applicable to other species. A robust learning scheme was created, comprising didactic teaching, interactive seminars, practical hands-on training, and computer-based learning. Practical training included a formative virtual assessment of clinical signs of health and welfare using Questionmark Perception, which improved the students' performance significantly. Validation studies are being carried out to establish if acceptable levels of inter-observer variability can be achieved by students conducting on-farm assessments of pig welfare during their extramural studies program. The resulting assessments of welfare will be analyzed in a cross-sectional epidemiological study to identify risk factors for good and poor welfare, and the results will be fed back to participating farmers. This new approach enables veterinary students to learn key transferable skills in the early stages of their education and provides a strong grounding in a holistic approach to animal welfare.
