February 2020 Lab News


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.



On February 12, Dr. Hans H. Stein participated in a meeting with FDA about regulations related to testing of baby formulas, this meeting was in Washington DC.


Personnel changes

We have a new visiting scholar, Jimena Ibagon is from the National University in Bogota Colombia. Jimena will be with us for the next 6 month. She will assist with the work in our calorimeter unit where she will do research to determine net energy values in diets fed to pigs.
