AI-powered devices have boosted efficiency of the farm, making animal monitoring and management more accurate. A monitoring necklace attached to each cow collects multiple data of the animal such as breath, rumination frequency, feeding situation and number of steps. These data are transmitted in real-time to veterinarians who can monitor the cows' milking and health conditions. Additionally, electronic ear tags provide a convenient method for identifying and managing individual cows, similar to giving each cow an ID. (Xinhua/Ma Xiping)
