Personnel changes
Two new students started their graduate work in the Stein lab this semester. Molly McGhee is originally from West Chicago. She worked with us for two years as an undergraduate while earning her degree in Animal Sciences. Hannah Bailey is from Eden Prairie, Minnesota. She earned her bachelor's degree from Iowa State University in 2016 with a major in Animal Science and a minor in Nutritional Science. She then went to work for Cargill Provimi before deciding to continue her education. Both Molly and Hannah will be pursuing Master's degrees.
Guillermo Fondevila Lobera is a visiting scholar from Spain. He will be here for two months before returning to finish his Ph. D. in monogastric nutrition at the Universidad Politécnica de Madrid.
Welcome to Molly, Hannah, and Guillermo!
New experiments
Vanessa started a study to determine the requirements for STTD calcium phosphorus to maximize growth performance and bone mineralization in 11 to 25 kg pigs.
Carly started an experiment on the effects of Sangrovit Extra on ATTD of energy and on concentration of DE and ME in diets fed to weanling pigs.
Von started a study of the effects of microbial phytase on degradation of phytate along the gastro-intestinal tract of growing pigs.
Travel
On August 10, Dr. Stein was in Gramado, Brazil, where he gave a talk titled "Requirements for digestible Ca by growing pigs." On August 22, he gave two talks in Santiago, Chile: "Nutritional value of soybean meal fed to pigs" and "Enhanced soybean meal in diets for weanling pigs." He then gave the same two talks in Quito, Ecuador on August 24.
Woongbi visited Korea for 2 weeks.
Diego Navarro traveled to the Philippines to visit family. Then, he went to Estonia to present at the 68th Annual Meeting of the European Federation of Animal Science (EAAP), where he gave a presentation on "Effects of physicochemical characteristics on in vitro and in vivo nutrient digestibility in pigs."
