Dr. Scott Carter

Dr. Carter is an associate professor who teaches principles of nutrition, swine science, special problems in advance swine nutrition, and protein nutrition.  He was the associate editor of American Society of Animal Science from 2008-2010. Dr. Carter is an Ex- Officio board member of the Oklahoma Pork Council.  His research interests are in the impact of diet on nutrient excretion and gaseous emissions, effect of alternative feedstuffs on growth performance and carcass traits, effects of feed additives in on growth performance, and carcass traits.

Dr. Adel Pezeshki

An understanding of energy balance regulation is critical for developing novel strategies to improve the metabolic health and growth in both animals and humans. The energy balance regulation and changes in body weight and body composition are dependent on controls operating on food intake, energy expenditure and metabolism. There is substantial evidence that both quality and quantity of dietary protein and amino acids profile alter the food intake, energy expenditure and metabolism. However, the physiological mechanisms by which dietary proteins or individual amino acids regulate energy balance and metabolism are largely unknown. Using pigs as experimental units, the goal of Dr. Pezeshki’s research is to investigate the potential of dietary protein and amino acids in modulating the energy balance, identify key molecules that regulate these changes and characterize the pathways for their action. Dr. Pezeshki’s group approaches the above aims by assessing various physiological parameters and mechanisms using variety of technologies and tools (e.g. indirect calorimetery, dual-energy X-ray absorptiometry and etc.).

Dr. Glenn Zhang

Now with the use of medically important antibiotics being banned for growth promotion in livestock animals in the U.S., more effective alternatives to antibiotics are urgently needed to ensure animal health and productivity.  Dr. Zhang’s group is in pursuit of two different approaches to the development of novel antibiotic alternatives by employing a series of the state-of-the-art technologies in molecular immunology, functional genomics, metagenomics, and bioinformatics.  One approach is to modulate the synthesis of endogenous host defense peptides (HDPs) with the goal to develop HDP-inducing dietary compounds for disease control and prevention ("Modulating Innate Host Defense").  The second approach is to manipulate the structure and function of intestinal microbiota for optimal health and production efficiency.
