System and method for detecting enteric diseases, in particular in animals, based on odour emissions

The invention relates to a detection system of enteric diseases in animals, comprising: a sensor device comprising suction means for suctioning air from an environment with said animals, sensor means configured to determine information about the type and concentration of a plurality of smelling molecules in said air and further configured to emit a signal representative of said information of smelling molecules; a transmission device configured to convey said signal representative of smelling molecules; a processing device of the self-learning type configured to receive and process said signal representative of smelling molecules, detecting a risk of enteric diseases in said animals associated with said information about the type and concentration of said smelling molecules; a signaling device configured to report to a user said risk of enteric diseases in said animals, before said enteric diseases arise. The invention also relates to a relative detection method of enteric diseases in animals.
