Resumen

Estrus detection is key to optimizing conception in cows and improving livestock reproductive efficiency. The conventional method requires continuous observation, demanding labor and time. We developed an IoT-based system that automates estrus monitoring using a multisensor device mounted on the cow’s neck. It collects data and transmits it via LoRaWAN to a Gateway, which forwards it to The Things Stack and then to TagoIO for visualization and storage. In field tests, after synchronizing estrus in a cow in the Peruvian Amazon, data was collected and analyzed. The system recorded physiological and behavioral information, showing that within 72 hours, movement and body temperature increased, indicating estrus. © The authors.
