Broilers use vocalization as a form of expression to communicate in various situations, such as warnings, alarms, territoriality, stress, fear, satisfaction, and hunger, among others. The analysis of variations in the frequency and patterns of these vocalizations allows us to make an accurate assessment of the animals’ health and welfare. This innovative practice uses bioacoustics to obtain quantitative measurements of broiler stress in a non-invasive manner, avoiding any human intervention. The system consists of a microphone installed above the broilers’ heads to capture their vocalizations and send the data to a processor mounted on a wall. This processor eliminates background noise that does not originate from the animals, ensuring a clean and accurate capture of their sound emissions.
