Clinical techniques for monitoring live stock health are insufficient, as they provide only sporadic information and require too much resource investment in terms of time and veterinary expertise. A sophisticated system capable of continuously assessing the health of individual animals, aggregating these data, and reporting the results to owners and regional authorities could provide tremendous benefit to the livestock industry. Such a system would not only improve individual animal health, but it would help to identify and pre vent widespread disease, whether it originated from natural causes or from biological attacks. This paper presents results from a prototype telemonitoring system that utilizes wearable technology to provide continuous animal health data. The infrastructure, hardware, software, and representative physiological measurements are presented.
