Edward Addo-Chidie
Adekunle Adebiyi
Kunle Adebiyi spent six months in 2013 in the Adeola Lab conducting studies on standardized ileal digestibility of amino acids in feed ingredients, including co-products of bioethanol production, for swine.
He visited from the Scottish Rural University College in the United Kingdom, where he conducted research on the nutritional value of bioethanol co-products for broilers and turkeys. His work provided data and practical recommendations for poultry producers on energy value, nutrient digestibility and optimal inclusion rates of wheat and corn distillers dried grains with solubles (wheat DDGS and corn DDGS) produced in bioethanol plants in the U.K.
The studies conducted at Purdue were designed to provide him with experience in swine nutrition.
Sunday Adetayo "Tayo" Adedokun
Sunday Adetayo “Tayo” Adedokun, PhD, earned his bachelor's in animal sciences from Obafemi Awolowo University in Ile-Ife, Nigeria. He came to Purdue University in 2002 to pursue a master's degree in nonruminant nutrition and continued toward a PhD, which he completed in 2007. His doctoral research focused on endogenous amino acid losses and standardized ileal amino acid determination in poultry. He also was involved in cross-species comparisons of endogenous amino acid loss determination.
He was a senior research associate in the Department of Animal Sciences at Purdue University.
As a postdoctoral research associate, he examined the role of feed components, supplements and mild coccidial vaccine challenge on nutrient and energy digestibility and utilization, as well as their effects on intestinal nutrient transporters, particularly sodium-dependent phosphate transporters (NaPi-IIb), markers of intestinal inflammation (interleukin-1b and toll-like receptor-4) and gut integrity (mucin, MUC2).
He also studied the role of different dietary treatments on the expression of NaPi-IIb in broilers and conducted digestible amino acid determinations in various poultry feed ingredients. His research interests included evaluating the effects of feed supplements, individually or in combination, on digesta passage rate.
Taken together, his research integrated applied and basic approaches to address nutritional questions in nonruminant animals, with a focus on understanding how feed additives and supplements — such as phytase, direct-fed microbials and enzymes — affected gut health, integrity and nutrient utilization.

Visiting Scholar in 2006
Adebisi (Bisi) Agboola
Adebisi Agboola worked in the lab from November 2009 to January 2010. She earned her MS in animal science from the University of Ibadan in Nigeria and pursued her PhD at the same university. Her research centered on the use of locally available feedstuffs in poultry production. She evaluated the digestible amino acid content of feedstuffs native to southwestern Nigeria and developed a model to incorporate that information into diet formulation on a digestible amino acid basis.

Changsu Kong
After earning his BS and MS in animal science and biotechnology from Seoul National University in 2002 and 2004, respectively, Changsu Kong joined the monogastric animal nutrition laboratory of Layi Adeola, PhD. As a PhD student, his work focused on amino acid nutrition.
In mixed diets, the proportional quantities of digestible amino acids from each feed ingredient are added together, and the sum represents the total digestible amino acids in the diet. This calculation assumes additivity of the digestible amino acid content of individual feed ingredients when they are combined.
Apparent and standardized ileal digestibility of amino acids (AID and SID) have commonly been used for diet formulation. However, the assumption of additivity for AID has been questioned because of underestimation of AID for most amino acids in cereal grains. His research focused on understanding the additivity and associative effects of amino acid digestibility in diets for swine and poultry.

Hengxiao Zhai
Hengxiao joined the Adeola Lab in 2008 to pursue his PhD. His research focused on the application of commercial enzymes in grower and finisher pigs. Exogenous enzymes were designed to target anti-nutritional components in high-fiber ingredients, potentially increasing the nutritional value of those ingredients for the animals.
Later in his doctoral work, he conducted research on determining the phosphorus requirements of pigs. This work was especially timely because phosphorus was expensive and environmental concerns were associated with its use in animal nutrition. Precisely measuring phosphorus requirements in pigs was both challenging and meaningful.
