Dr. Patience’s area of research is nutrition of the pig. His specific focus is on 1) energy metabolism, 2) ingredient evaluation, and 3) feeding and management in the nursery and finishing barns. Further details are available on the Applied Swine Nutrition Research Program website.

Dr. Patience provides extension support to the Iowa pork industry in the area of swine nutrition.
