For instance, animal-mounted sensors can automatically and continuously monitor health indicators, allowing for the early detection of diseases before they spread widely within a herd (Yazdanbakhsh et al., 2017). These systems can forecast illnesses up to seven days in advance, significantly reducing morbidity and mortality rates. Wearable sensors and IoT-based systems enable the monitoring of individual animal health trends by tracking vital signs such as temperature, heart rate, and activity levels in real-time (Arshad et al., 2022). This continuous data collection allows for the detection of deviations from normal health patterns, facilitating timely interventions. Smart sensors can also track the effectiveness of vaccinations and treatments by monitoring physiological responses and health improvements over time. This data-driven approach helps in assessing the success of medical interventions and adjusting treatment plans as necessary (Džermeikaitė et al., 2023). 3.2 Improving animal welfare and productivity Smart sensors contribute to reducing stress in livestock by managing environmental conditions such as temperature and humidity. Intelligent systems can regulate these parameters automatically, ensuring optimal living conditions and minimizing stress-related health issues (Rajendran et al., 2023). Reproductive health monitoring is enhanced through the use of biosensors that track physiological indicators related to fertility and pregnancy. These sensors provide valuable insights into reproductive cycles, enabling better management of breeding programs (Halachmi et al., 2019). Smart sensors help optimize feeding schedules and nutrition plans by monitoring eating behaviors and nutritional intake. This data allows for the adjustment of feeding strategies to improve growth rates and overall health (Ronald and Raman, 2024). 3.3 Precision livestock farming Precision livestock farming leverages data from smart sensors to allocate resources more efficiently. By analyzing health and environmental data, farmers can make informed decisions about resource distribution, enhancing productivity and sustainability (Iwasaki et al., 2019). Automation of health-related tasks is facilitated by smart sensors, which reduce the need for manual labor in monitoring and managing livestock health. This automation leads to cost savings and increased efficiency in farm operations. Smart sensors integrate with precision breeding programs by providing detailed health and genetic data. This integration supports the selection of optimal breeding pairs, improving the genetic quality and productivity of livestock (Go et al., 2022; Rahmawati et al., 2023) 4 Advantages of Using Smart Sensors 4.1 enhanced real-time monitoring capabilities Smart sensors enable continuous data collection, providing a constant stream of information about livestock health. This capability allows for the monitoring of vital signs such as heart rate, temperature, and activity levels, which are crucial for early detection of health issues. The integration of IoT and wireless sensor networks facilitates the seamless collection and transmission of data, ensuring that farmers have access to real-time health insights (Rahmawati et al., 2023). The use of smart sensors allows for remote health management, enabling farmers to monitor livestock from distant locations. This is particularly beneficial for large-scale operations where physical presence is not always feasible. IoT platforms and cloud-based systems provide the infrastructure for remote monitoring, allowing data to be accessed and analyzed from anywhere. This reduces the need for frequent on-site visits and allows for more efficient farm management (Rajendran et al., 2023). Smart sensors are equipped with the capability to send immediate alerts when anomalies are detected in the health data of livestock. This feature is critical for prompt intervention, potentially preventing the escalation of health issues (Yazdanbakhsh et al., 2017). Automated notification systems integrated with smart collars or other wearable devices ensure that farmers and veterinarians are quickly informed of any irregularities.
