The South Dakota State University Dairy Science Department welcomes three new professionals; David Casper, Assistant Professor in Dairy Science, Tracey Renelt, SDSU Extension Field Specialist in Dairy and Melissa Schmitt, Assistant Manager for the Dairy Research and Training Facility.
David Casper will focus on production in his new position as Assistant Professor in Dairy Science.

After completing his Ph.D. at SDSU, Casper was a Research Dairy Scientist with the Agriculture Research Service of USDA at Beltsville, MD where he researched the energy metabolism of dairy cows fed diets containing high fat feed ingredients, nonstructural carbohydrates, or different forage sources using the respiration chambers at the Energy Metabolism Unit.
He later joined Cargill, Inc., as Dairy Innovation Development Manager researching and designing new feeding programs and products. He moved to Agri-King, Inc. in 1997 as Consulting Dairy Nutritionist and was eventually promoted to Vice President of Nutrition.
