Acoustic description of the soundscape of a real-life intensive farm and its impact on animal welfare: a preliminary analysis of farm sounds and bird vocalizations

| Sumario: | Poultry meat is the world’s primary source of animal protein due to the low cost andit is widely eaten at global level. However, intensive production is required to sup-ply the demand although it generates stress to animals and welfare problems whichhave to be reduced or eradicated for better birds health. In this study, bird wel-fare is measured by some indicators:CO2, temperature, humidity, weight, deaths,food and water intake. Additionally, we approach the acoustic analysis of the bird’svocalisations as a possible metric to add to the aforementioned parameters. Forthis purpose, an acoustic recording and analysis of an entire production cycle ofan intensive broiler Ross 308 poultry farm in the Mediterranean area has been per-formed. The acoustic dataset generated has been processed to obtain the EquivalentLevel (Leq), the mean Peak Frequency (PF) and the PF variation, every 30 minutes.This acoustical analysis aims to evaluate the relation between traditional indicators(death, weight andCO2) and acoustical metrics (equivalent level impact -Leq-, PeakFrequency - PF- ) of a complete intensive production cycle. As a results relationbetweenCO2and humidity versusLeqhas been found, as well as decrease in thevocalisation when the intake of food and water is large. |
