Utilizing wearables to track vital signs and activity levels is a key advancement in monitoring livestock health because these devices can provide real-time data on various health indicators. Wearables, such as smart collars or sensors, can monitor parameters like heart rate, body temperature, and movement patterns. This continuous stream of information allows farmers and veterinarians to detect potential health issues early, enabling timely interventions and improving overall herd management.

In contrast, the other options do not provide the same level of precision or efficiency. Aerial surveillance with drones can offer visual insights but lacks the specific health-related data that wearables provide. Traditional farming tools do not have the technological capabilities to monitor health parameters, and relying solely on manual checks can be time-consuming and prone to human error, making it less effective in maintaining optimal livestock health.
