The principle objective of my work at the Tidewater Agricultural Research and Extension Center (TAREC) is to provide the Commonwealth with a high quality research program in reproductive physiology that is directed at solving problems in the Virginia and U.S. swine industries. I adhere to the philosophy that a mix of applied and basic research is the most effective approach toward solving swine industry problems. Applied research addresses acute challenges in the industry while a basic component in agricultural research is necessary for long-term advances and because scientists cannot effectively control what they do not completely understand. Specific research interests include enhancing semen quality and libido in boars used for artificial insemination, hormonal control of the gilt estrous cycle, and the impact of nutrition and management on sow reproductive performance.
I have the responsibility to develop and implement extension education programs for swine producers in the area of breeding herd management. My partial extension appointment allows me to keep abreast of the swine industry. Moreover, I can deliver, first hand, results of my research not only to the scientific community but to the end users as well. Finally, I provide leadership and management oversight of the TAREC swine research facilities. This includes supervision of two classified technicians in the operation of the Research Boar Stud (40-boar capacity) and the farrow-to-finish herd and facilities (96-sow capacity).
