Hans-Henrik Stein

Hans-Henrik Stein is a Professor in both Animal Sciences and Nutritional Sciences at the University of Illinois. His research focuses on animal nutrition, particularly digestibility studies in pigs and other livestock, with emphasis on mineral and amino acid metabolism, feed additives, and regional variability in feed composition. He has authored 392 publications and holds three major awards in nonruminant nutrition research and extension.

Key research topics include calcium and phosphorus digestibility, microbial phytase effects, thermal stress in sows, and repeatability of nutritional measurements. His work frequently addresses practical applications in livestock feed formulation and mineral utilization efficiency.

• Awards: AFIA-ASAS Award (2010), ASAS Extension Award (2019), Gary L. Cromwell Award (2018)
• Collaborations: Global research networks in agricultural and biological sciences

Dr. Stein’s lab evaluates nutritional strategies to optimize animal growth performance while reducing environmental impacts through efficient feed utilization. Recent studies emphasize regional feedstuff variations and their implications for standardized nutritional guidelines.
