Major Responsibilities/Research Interests
Doug’s research program has a strong applied research focus; relevance to the poultry industry remains an important consideration in his approach to research. In addition to practical research on feedstuff quality and dietary supplement evaluation in poultry diets, Doug’s work focuses on nutrition-immune function interactions and bone biology in meat- and egg-type poultry. In addition, he has conducted field research trials in commercial poultry facilities in Canada, Colombia and Ecuador. In 2016, he spent a 6-month sabbatical in Colombia, working with a major broiler integrator. He is currently part of the National Research Council’s committee to revise and update the 1994 Nutrient Requirements of Poultry.
Doug currently teaches introductory animal nutrition (ANSC 260 Fundamentals of Animal Nutrition) and monogastric nutrition (ANSC 462 Mongastric Nutrition) courses at the undergraduate level, and is a co-instructor for a graduate-level course in advanced animal nutrition and metabolism (AFNS 569 Advanced Nutrition and Metabolism). In addition, he periodically supervises independent study courses at the undergraduate (ANSC 400) and graduate (AFNS 500) levels.
