Course Taught

Fall and Spring Semesters:

  • APSC 4004: Contemporary Issues in Animal and Poultry Sciences. Provides guest lectures focused on Contemporary Issues facing the Pork Industry.

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 the impact of nutrition and management on sow reproductive performance, enhancing growth and animal well-being in suckling and nursery pigs, and novel strategies for mitigating the effects of pork production on environmental quality.

Swine Physiology, Reproduction and Management Program

I have the responsibility to develop and implement extension education programs for producers in the diverse swine industry of Virginia, that Includes large corporate farms and contract growers, small-scale and niche market pig farmers, as well as 4-H and FFA Youth swine exhibitors.  I serve as an ex officio member of the Virginia Pork Council Board of Directors and as an Editor for the United States Pork Center of Excellence's Pig Information Gateway.
