OUR GOAL IS TO HELP THE DAIRY SECTOR SOLVE THE PROBLEM OF ANIMAL REPLACEMENT AND INSEMINATION DECISIONS THROUGH THE APPLICATION OF DATA SCIENCE METHODS ON BIG FARM DATA, COUPLED WITH THE DEVELOPMENT OF AN ECONOMIC OPTIMIZATION TOOL ON A CYBER PLATFORM. THERE IS AN INCREASINGLY LARGE AMOUNT OF DATA COLLECTED ON MANY DAIRY FARMS, SUCH AS THROUGH SENSORS AND GENETIC TESTING, BUT THESE DATA ARE NOT WELL INTEGRATED INTO ACTIONABLE DECISION-SUPPORT THAT HELP SOLVE CURRENT PROBLEMS EXPERIENCED BY DAIRY FARMERS. TWO MORE PROMINENT PROBLEMS ARE THE ANIMAL REPLACEMENT PROBLEM (WHEN TO REPLACE A COW BY ANOTHER COW) AND THE HOW TO ACT UPON A BREEDING OPPORTUNITY (GETTING THE FEMALE PREGNANT, INCLUDING THE QUALITY OF THE CALF). USING DATA SCIENCE WITH EXISTING AND NEW SENSORS DATA, WE HELP SOLVE THESE PROBLEMS THROUGH 4 OBJECTIVES: 1) IMPROVE AND FURTHER DEVELOP A TOOL THAT SUPPORTS OPTIMAL DECISIONS REGARDING REPLACEMENT AND INSEMINATION CHOICES FOR HEIFERS AND COWS. THIS TOOL PROVIDES BETTER SUGGESTIONS WHEN IT USES MORE ACCURATE PHENOTYPIC PREDICTIONS; 2) IMPROVE THE PREDICTION OF PHENOTYPIC FUTURE FERTILITY AND MILK PRODUCTION OF A DAIRY HEIFERS AND COWS BY INCORPORATING GENETIC INFORMATION, HEALTH EVENTS AND SENSOR INFORMATION THROUGH DATA SCIENCE METHODS; 3) WORK WITH THE DAIRY INDUSTRY TO DEVELOP, TEST AND IMPROVE THE TOOL, AS WELL AS MEASURE IMPACT ON DECISION-MAKING, AND 4) SECURE LONG-TERM IMPACT OF OUR APPROACH AND CYBER PLATFORM THROUGH LICENSING WITH COMMERCIAL PARTNERS. OUR PROJECT WILL PRODUCE AN INTEGRATED DECISION SUPPORT SYSTEM USING DATA SCIENCE THAT RESULTS IN DECISION MAKING ON FARMS THAT RESULTS IN MORE EFFICIENT, PROFITABLE, AND SUSTAINABLE MILK PRODUCTION.
