** AWARDS ISSUED PRIOR TO JANUARY 20, 2025, WERE FUNDED UNDER PREVIOUS ADMINISTRATIONS AND MAY NOT REFLECT THE PRIORITIES AND POLICIES OF THE CURRENT ADMINISTRATION.** THE NUMBER OF SKILLED LABORERS FOR MONITORING AND MOVING UNCONFINED ANIMALS IS DWINDLING WITHIN THE US LIVESTOCK INDUSTRY. NEW TECHNOLOGY UTILIZING SMALL DRONES (UNMANNED AIRCRAFT SYSTEMS OR UAS) AND ADVANCED PHOTOGRAPHY METHODS (PHOTOGRAMMETRY) NOW ALLOWS FOR AN ALTERNATIVE MEANS FOR MONITORING AND MOVING CATTLE. THE COST OF THESE NEW TECHNOLOGIES AND THE COMPLEXITY OF IMPLEMENTATION ARE A CHALLENGE TO ADOPTION AS MARGINS ARE SMALL AND PRODUCERS HAVE LIMITED TIME TO LEARN COMPLEX SYSTEMS.THUS, THE OVERARCHING GOAL OF THIS WORK IS ADVANCING THE UNDERSTANDING OF THE UAS AND BEEF CATTLE INTERACTION IN PASTURE AND COLLECTING PHYSIOLOGICAL MEASUREMENTS REMOTELY. WE PROPOSE FOUR SPECIFIC OBJECTIVES: 1) DEVELOP A NOVEL MULTI-AGENT UAS CONTROL TECHNIQUE FOR SEMI-AUTONOMOUS INTERACTION WITH LIVESTOCK; 2) ESTABLISH UAS BEEF CATTLE REACTION RESPONSE; 3) QUANTIFY THE ACCURACY OF UAS BASED CATTLE VOLUME MEASUREMENTS FROM THE UAS; AND 4) DEVELOP UAS ECONOMIC MODELS FOR THE LIVESTOCK INDUSTRY. THE OUTCOMES OF THE PROJECT WILL OFFER A SIMPLIFIED APPROACH FOR HERDING AND MONITORING LIVESTOCK, PROVIDE FLIGHT RECOMMENDATIONS CONCERNING ANIMAL PROXIMITY, PRESENT MODELS FOR COW WEIGHT ESTIMATION, AND OFFER INSIGHTS INTO THE OPTIMUM NUMBER OF DRONES REQUIRED.THE ANTICIPATED IMPACT FOR PRODUCERS WOULD BE A STREAMLINED APPROACH TO UTILIZING UAS FOR THE MONITORING AND MOVEMENT OF CATTLE. THE UTILIZATION OF UAS ON LIVESTOCK OPERATIONS WILL FACILITATE A WORKLOAD REDUCTION FOR PRODUCERS.
