Research Interests

Dr. Applegate’s translational research program explores mechanisms of nutrient interaction with and within the gastro-intestinal tract to ultimately improve nutrient absorption and retention. A primary research focus Dr. Applegate’s lab explores methods for reducing phosphorus, nitrogen and ammonia excretion including determination of amino acid digestibility of feed ingredients, ingredient selection, formulation level, use of supplemental amino acids and use of acidulants. A second major research focus explores contributions of diet, pathogens, toxins, and stressors to endogenous nutrient and energy losses from the gastro-intestinal tract and dietary strategies to minimize them.
