Saulo Menegatti Zoca is an Assistant Professor and Extension Beef Cattle Specialist in the Department of Animal Science at the University of Tennessee. His program focuses on advancing reproductive efficiency in beef cattle by integrating applied and translational research with producer-driven Extension. Dr. Zoca’s work has examined bull fertility from multiple angles, including the identification of sperm proteins and metabolites associated with fertility, the use of proteomics and flow cytometry to predict reproductive outcomes, and the impacts of nutrition, management, and herd health on pregnancy establishment and loss. Through the coordination of statewide bull and heifer development programs, applied field studies, and educational efforts, his work delivers practical strategies to improve breeding management, enhance herd fertility, and support the long-term sustainability of beef production systems.
