Research Summary

Major objectives of my research have been to quantify the environmental, management and biological (including animal’s genotype) factors on health and welfare of farm animals for a variety of herd environments and production practices. In my research I have used mathematical modeling to describe the behavior of the biological systems and evaluate the impact of various management practices, epidemiological tools to quantify risk factors for health and welfare of animals, decision analysis to rank management interventions. I have adopted a system approach that integrates animal health with welfare and production throughout my research career. This approach generates the type of information needed to develop decision support systems, to prioritize the emphasis to be placed on health, welfare, fertility and longevity in the management programs of the dairy cows or other livestock at the farm level. This approach to research also provides additional support to the ongoing transition from the classical animal health program with emphasis on clinical diagnosis and therapy to a more preventive animal health program based on risk assessment.
