Project summary:

With global warming, heat waves are becoming more frequent. In order to develop practices that limit the impact of heat stress, it is first necessary to describe in detail the synchronisation of the physiological and behavioural mechanisms that enable or prevent the animal from adapting. The amplitude of variations in physiological parameters and the latency before returning to equilibrium vary greatly from one pig to another. The successful candidate will be required to correlate high-frequency data provided by new digital sensors with temperature variations, food intake and the behaviour of each pig. This will involve setting up an experiment, taking biological samples from animals and analysing the multiple and heterogeneous data collected by developing and mobilising methods for analysing temporal data.
