Ph.D. Dissertation: Standardized amino acid digestibility determination in poultry

MS Thesis: Metabolizable energy value of meat and bone meal

Dr. Adedokun obtained his B.S. from the Department of Animal Science, Obafemi Awolowo University, Ile-Ife, Nigeria. He then came to Purdue university in 2002 to pursue an MS degree in non-ruminant nutrition and continued towards a PhD in 2004. His PhD research focused exclusively on endogenous amino acid (EAA) and standardized amino acid determination in poultry. He was also involved in across species comparison of EAA losses determination. Currently, he is a postdoctoral research associate in the department of animal sciences at Purdue University.

As a postdoctoral research associate, he has taken a comprehensive look at the role of some feed components, feed supplements/additives, and mild coccidial vaccine challenge (stress, in broilers) on nutrient digestibility/utilization and their effect on intestinal nutrient transporters (especially sodium dependent phosphate transporters, NaPi-IIb), markers of intestinal inflammation (interleukin-1b and toll-like receptor-4, TLR-4), and gut integrity (mucin, MUC2). Additionally, he has been involved in studies that look at the role of different treatments and growth (development) on the development of NaPi-IIb in broilers. Furthermore, he is also involved in digestible amino acids determination in different feed ingredients in poultry. My interest also includes determining the effect of different feed supplements (individually or in combination) on digesta passage rate and intestinal microbial shift (using the denaturing gradient gel electrophoresis, DDGE method). Taken together, his current research is focused on the use of both the applied and basic tools to address some of the nutritional questions in non-ruminant animals; with a specific goal of determining the mechanisms through which feed additive/supplement (e.g. phytase, direct fed microbial, enzymes, etc) affect gut health and integrity as well as nutrient use.
