Good business decision-making in dairy farming depends on the availability of high quality and current data about the profitability of the business production unit: the cow. Every day producers are faced with important decisions related to culling or keeping, breeding, grouping, treating, and feeding cows, among many others. Unfortunately, despite the many technologies and data available today, dairy producers continue to lack tools that provide an accurate and detailed account of individual cow profitability, with minimal effort, and in real time. Thus, most of the individual cow decision-making continues to be done based on averages for the herd or groups, parameters that do not truly reflect cow profitability, and in some cases perception or "gut feeling". To help dairy managers overcome this barrier to good business decision-making, our research group developed the "MyCow$", a software tool that leverages dairy data to automatically calculate the profitability of individual cows in real time.
