Recently, the importance of the impact of mental health on animal welfare has become evident, and animal welfare is now assessed through both physical and mental health. However, tools to scientifically and easily measure the affective lives of animals are still lacking. One promising tool to assess animal emotions is through vocalisations. Our project proposes to develop a robust system for identifying emotions in fattening pigs (from birth to slaughter), using vocalisations, which could be used to obtain welfare outcome indicators on-farm. This will be done by gathering European groups experts on vocal indicators of mental states in pigs (FR, DE, CH, NO, CZ). The project includes three main tasks. The first task aims at identifying vocal indicators of emotions in pigs. This will be done with a meta-analysis on existing and new data recorded within the project. Indeed, the groups already own a large number of audio data recorded in situations associated with different emotions, ranging from stressful husbandry procedures (e.g. castration and handling) to positive situations (e.g. social reunion and post-nursing interactions). Because the recordings vary in terms of pig breed, sex, age and recording technics, we will also carry out more recordings in standardised conditions, in order to obtain a baseline for the recognition system, and in missing situations (positive states and slaughter). The second task aims at developing a recognition tool able to identify emotions using vocalisations. It will consist in testing different classification methods/models, in order to choose the more appropriate to develop a system that could reliably identify pig emotions. Then, the recognition software will be built. The third and last task will consist in testing and validating the system. To this aim, the teams will test it in various situations at their own research stations and on-farm (from birth to slaughter).
