Factors such as labor availability, achieving excellent reproductive performance, and maintaining fresh cow health are some of the most pressing challenges for dairy farms. The increasing trend of larger herds and farm consolidation leaves small dairy farms in a vulnerable situation, continuously at risk, and in need of making changes or adopting new technologies to remain viable. Thus, it is essential for small farms to make informed decisions accounting for economic impacts when considering changes to management or capital investments. A Partial Budget is a financial management tool that can estimate the effect on returns and costs of a potential change in a business. This case study aimed to help a hypothetical small dairy farm make an informed decision about adopting Automated Health Monitoring Technology by accounting for changes in returns and costs of adopting this technology.
