Neil Jaworski was selected to receive the David H. and Noraine A. Baker Graduate Fellowship for the 2015-2016 academic year. The Baker Fellowship in Animal Sciences annually recognizes an outstanding doctoral student in the Department of Animal Sciences at the University of Illinois at Urbana-Champaign.

Mary Dickerson, an undergraduate who works in the Stein Lab, is the first student to be accepted into the ACES in the Netherlands Summer Internship program. Mary will be working for a dairy farm in the Netherlands.

Personnel changes

Oscar Rojas left to take a position as Swine Nutritionist at Devenish Nutrition USA. It will be strange not having Oscar in the lab -- he's been here a long time! We wish him the very best, and know that he will be successful in his new career.

Trine Pedersen joined the lab as a visiting scholar. Trine finished her Master's degree last month at Aarhus University in Denmark, where she studied nutrition for lactating sows. At Illinois, she will study growth performance of weanling pigs fed canola meal. She will be here for about a year.

Lab activities

Laura started an experiment to determine if there are differences in growth performance of pigs fed diets containing calcium carbonate ground to different particle sizes. She also started an investigation of the digestibility of calcium in diets containing different sources of fat.
