Department of Animal Sciences, University of Illinois at Urbana-Champaign
In the Stein Monogastric Nutrition Laboratory, Dr. Hans Stein and his graduate students and employees conduct research with monogastric animals to evaluate feed ingredients, nutrient requirements, and feeding strategies. A number of research techniques are used in the laboratory and in particular, Dr. Stein's group has expertise in the area of measuring ileal and total tract energy and nutrient digestibility, and in measuring energy and nutrient balances.

This week we celebrated that Drs. Ibagon, Jaramillo, and Fanelli (previously known as Jimena, Bibiana, and Natalia) received their diplomas, were hooded, and celebrated before they continue on their life journey, which undoubtedly will lead them to great achievements. We have been privileged to have Jimena, Bibiana, and Natalia in our team and wish them the very best in the future. Thank you for all your contributions to our team.

We invite you to read our April Newsletter 2026:
Stein Nutrition Newsletter, April 2026 Diego Guerrero, Ph D. student in the Stein Monogastric Nutrition Lab, discusses about differences in digestible calcium among 14 sources of calcium carbonate sourced from Latin America when fed to growing pigs. Adapted from a presentation at the 2026 ASAS Midwest Section meeting, March 9-11, 2026.

Bibiana Jaramillo successfully defended her doctoral dissertation today. Her seminar focused on the potential for improving the digestibility of minerals, energy, and amino acids by using 25OHD3 or phytase in diets for pigs. Bibiana will soon return to her native Colombia to continue her career. Best of luck Bibiana. We are very proud of you.

Today Jimena Ibagon successfully defended her PhD dissertation about the use of soybean meal in diets for pigs. Jimena has been very productive during her time as a Graduate student in our team and completed 8 experiments towards her dissertation. She hope to continue her career as a nutritionist in a commercial feed company in the US or somewhere in Latin America. Big congratulations to Jimena and best of luck in the future.

Natalia Fanelli successfully defended her PhD dissertation yesterday. She gave a seminar discussing her research investigating selected proteins from the salmon, seaweed, and egg industries as potential amino acid sources for pigs, humans, or dogs. She then had a chance to defend her dissertation in front of her committee. Soon-to-be Dr. Fanelli is looking for a job in the food or feed industry or in regulatory agencies. Wishing you the best of Luck Natalia.
