BROOKINGS, S.D. – South Dakota State University Extension highlights that the SDSU Department of Animal Science students and faculty will present their latest research and Extension projects at this year’s Midwest Section meeting of the American Society of Animal Science.
The annual meeting will be March 12-15 in Madison, Wisconsin, and will include competitions for undergraduate and graduate students, symposiums, and research presentations from faculty and students.
Graduate and undergraduates compete in oral and poster presentations of their research work. The annual conference also offers a chance to see national and international research work in the animal science industry.
SDSU Department of Animal Science researchers and SDSU Extension specialists will present their latest findings on breeding, nutrition and production efficiency in livestock operations. The conference includes a full slate of research project presentations from other universities as well, spanning beef cattle, dairy cattle, swine and sheep.
Some of the topics SDSU Extension and Animal Science faculty will talk about include the effect different hybrid rye processing methods can have on steers’ growth, and how ramped piglet housing in the nursery phase can improve loading times during transportation to market.
