Measuring the national economic benefits of reducing livestock mortality

A simple model for calculating the macroeconomic impact of improving livestock efficiency through better herd health is presented. Using economic surplus analysis with preweaning mortality in swine as the example, the model demonstrates the importance of improving livestock production efficiency in the face of international competition and how consumers gain from improved animal health. The model can be used to examine the appropriateness of expenditures on animal disease control programs and animal health research.
