SDSU researchers to present at American Society of Animal Science meeting

South Dakota State University researchers, undergraduate and graduate students, and SDSU Extension experts will present a variety of research results at the virtual meeting of the American Society of Animal Science Midwest Section on March 8 - 10.

“I am very proud of the work of our faculty and students,” says Joseph Cassady, head of SDSU’s Department of Animal Science and interim head of the Department of Dairy and Food Science. “Research productivity has greatly increased over the past five years. This is a reflection of our outstanding faculty and recent investments in infrastructure which have enabled their success.”

SDSU researchers will be presenting 29 research abstracts, with 18 being shared as presentations and 11 as posters.
