The thermal and humidity environment in livestock housing (air temperature, humidity, and airflow) is a key factor affecting pig’s comfort, physiology, and production performance. Our previous research found that pigs exhibit a sensitive biological response mechanism to changes in the thermal and humidity conditions inside the housing. Therefore, the physiological parameters such as respiratory rate, body temperature, and heart rate, as well as behavioral states like lying and clustering of pigs under different thermal and humidity conditions were monitored in this study. By using the pigs’ physiological parameters as biosensors and integrating the indoor environment data monitored by physical sensors, an evaluation method for assessing the comfortable level of the pig housing environment was developed. The results show that the comprehensive evaluation method established in this study has higher sensitivity and can more objectively assess the comfort level of the thermal and humidity environment in the housing, providing a scientific basis for environmental regulation.
