Validation of a Sound Recording Device for Swine Cough Detection.
Cough, nursery, swine, technology, prevention.
In the nursery phase, where a warmer environment is required, often the ventilation in the pig farms is reduced to maintain the warmth, which leads to an increase in the concentrations of unwanted gases resulting in respiratory tract pathologies in pigs, which is the most frequent clinical sign. Monitoring for the early identification of this sign becomes essential to prevent the health and performance of the herd from being compromised, by providing treatment at the right time and reducing the indiscriminate use of antimicrobials. As an alternative to assist in the diagnosis of coughing, this work aims to validate a device that identifies coughing. It will send real-time alerts to a mobile phone, and the readings can be extracted to computer spreadsheets for the necessary statistical analysis. This device also includes sensors that will measure gases (CO2), temperature, and humidity. The experiment will be conducted in three pig nurseries in the municipality of Concórdia, Santa Catarina, Brazil. One device will be installed approximately every twenty meters along the length of each barn, at a height of about one and a half meters. Every three days, a veterinarian will count the instances of coughing to compare the information with the device. If the herd shows signs of coughing with pathological characteristics, euthanasia of piglets will be performed, and samples will be collected for diagnosis and identification of the involved agents.
