Robotic milking and other precision dairy technologies improve profitability

U.S. dairy farmers profit from adopting robotic milking and other precision dairy technologies, according to research from USDA, Economic Research Service (ERS). Precision dairy farming involves using technology to help manage cows more efficiently. Some tools have been around for years, such as cow production records, artificial insemination, and nutritionist-formulated diets. Others, like robotic milking systems—in which a dairy cow enters a box-like stall, is milked automatically without manual labor, and then exits—are still emerging. To see how using various precision dairy technologies side by side can affect profit, ERS economists analyzed U.S. dairy operations using data from the Agricultural Resource Management Survey (ARMS). After accounting for farm attributes and operator characteristics, they found that robotic milking increased dairy net returns by $3.15 per hundredweight (cwt), on average, relative to nonadopters. Farms using more than one type of precision dairy technology (data support, breeding, and/or non-robotic milking) increased net returns by $3.18 per cwt, relative to nonadopters. Net returns are a measure of profitability that subtract the dairy farm’s operating costs and overhead expenses from milk and cattle sales and other dairy-related income. This information is drawn from Precision Dairy Farming, Robotic Milking, and Profitability in the United States, published in January 2026.
