The first-ever wearable device for cows, designed to maximize production output with enhanced efficiency, monitors eight vital signals: heart rate, respiration, feed intake (RFI), rumination, estrus, activity levels, lameness, and weight gain. This easy-latch device addresses the growing challenges of large-scale farming by providing early detection of infections and optimizing farm management. It also supports national disease control efforts and enables feed companies to enhance brand loyalty and sales by bundling this advanced technology with their products.
