Dr. Wickersham teaches graduate level courses and laboratories in animal nutrition. He also directs research in ruminant nutrition with an interest in forage utilization and nitrogen metabolism. His previous research has focused on protein supplementation to cattle consuming low-quality forage and nitrogen metabolism in cattle consuming diets that are deficient in nitrogen. Future research goals include determining optimum supplementation strategies for ruminants consuming forages of divergent nutritive values and furthering our understanding of nitrogen metabolism in ruminants.
