Personnel changes

Kelly Peper, who earned her Ph. D. last month, started her new job as Technical Support and Research Nutritionist with Ralco Nutrition in Minnesota. Kelly's husband, Mark Peper, is now working at Ducks Unlimited. We wish them all the best.

Matheus Philip Santos Amorim joined us as a visiting scholar. Matheus is studying animal science at the Universidade Federal dos Vales do Jequitinhonha e Mucuri (Federal University of the Jequitinhonha and Mucuri Valleys) in Jequitinhonha, Minas Gerais, Brazil. He will be here until August.

Diego Rodríguez returned for another stint as a visiting scholar. Diego did an internship in the Stein lab from August 2010 to August 2011, and was a visiting scholar from October 2011 to April 2012. He just can't stay away!

Lab activities

Laura finished farm work on an experiment to determine if there are differences in growth performance of pigs fed diets containing calcium carbonate ground to different particle sizes.

Trine began studying the effects of dietary energy level and an exogenous enzyme on growth performance of weanling pigs fed diets containing high protein or conventional canola meal.

Caroline finished farm work on an experiment to determine digestible calcium requirements for 25 to 50 kg pigs.

Diego N. started a study of the effects of physicochemical characteristics of feed ingredients on the in vivo total tract digestibility of dry matter, energy, and nutrients.

Travel

Trine, Jeru, Diego, John, Neil, Maryane attended the Alltech REBELation meeting May 16-20 in Lexington, Kentucky.

Dr. Stein traveled to Poland to attend the 13th International Symposium on Digestive Physiology of Pigs in Kliczków. On May 19, he was presented with the DSM Nutritional Sciences Award "for his impressive career in the field of sustainable swine nutrition research and for nurturing future talent in animal nutrition."
