BROOKINGS, S.D. – South Dakota State University Department of Animal Science students and faculty will present their latest research and Extension projects at the 2024 Midwest Section meeting of the American Society of Animal Science.
This year’s meeting is March 10-13 in Madison, Wisconsin, and will include student competitions, symposiums and presentations highlighting the research students and faculty are conducting.
During the annual conference, graduate and undergraduate students share research results via oral and poster presentations, and gain access to other national and international animal science research work.
Among those attending this year’s conference are three graduating student research assistants presenting the results of multi-year projects focused on various aspects of swine health.
Lauren Olson and her advisers studied the effects of feeding more soy protein and the amino acid methionine on sow health around the time they give birth. Garrin Shipman will present he and his advisers’ research into the effects of post-MSC DDGS (dried distiller’s grains used for feed after they have gone through a patented stillage, or protein separation, process) on nutrition and digestibility compared to other sources of fiber.
Another graduate research assistant, Katlyn McClellan, and undergraduate Sydney Sheffield researched how hemoglobin concentration impacts sow farrowing duration. McClellan will also present her research into the effects of hemoglobin changes in sows and their piglets over two reproductive cycles.
The conference includes a full slate of research presentations spanning different livestock operations. In addition to the graduate student presentations, SDSU Department of Animal Science researchers and SDSU Extension specialists will present their latest findings on breeding, nutrition and growth performance of swine, beef cattle, sheep and bison.
“The Midwest ASAS annual meeting provides a platform to share new information, learn and discuss research updates, and address animal production industry challenges,” said Ryan Samuel, assistant professor and SDSU Extension Swine Specialist.
The American Society of Animal Science Midwest section comprises South Dakota, Wisconsin, Illinois, Indiana, Iowa, Kansas, Michigan, Minnesota, Nebraska, North Dakota and Ohio from the U.S., along with the Canadian provinces of Manitoba and part of Ontario.
