Pat Jaynes
Lab Manager

Pat Jaynes is a laboratory technician at Purdue University, West Lafayette. Born in Lafayette, Indiana, Pat received a Bachelor degree in Biology at Purdue in 1986. Mrs. Jaynes earned a Master degree in Early Childhood Education in 1995. In 2000, she accepted her current position in Animal Sciences as lab manager of a monogastric nutrition lab with Dr. Todd Applegate and Dr. Layi Adeola. Previously, she worked with Dr. Bill Muir and Dr. John Patterson, both in Animal Sciences.

One of Mrs. Jaynes' greatest rewards in research is sharing joys and tribulations of animal research with graduate and undergraduate students. Mrs. Jaynes hopes to be a valuable resource in student's academic careers.

Mrs. Jaynes and her husband, Blair are blessed with one daughter, Madison.

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 M.S. degree in non-ruminant nutrition and continued towards a Ph.D. which he completed in 2007. His Ph.D. research focused exclusively on endogenous amino acid (EAA) losses and standardized ileal amino acid determination in poultry. He was also involved in across species comparison of EAA losses determination. Currently, he is a senior research associate in the department of animal sciences at Purdue University.

As a postdoctoral research associate, he took a comprehensive look at the role of some feed components, feed supplements/additives, and mild coccidial vaccine challenge on nutrient and energy 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 dietary treatments on the expression of NaPi-IIb in broilers. Furthermore, he is involved in digestible amino acids determination in different feed ingredients in poultry. His interest also includes evaluating the effect of different feed supplements (individually or in combination) on digesta passage rate. 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.

Adekunle Adebiyi
Visiting Scholar

Kunle is spending 6 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.

Kunle is visiting from the Scottish Rural University College, United Kingdom, where he is conducting research on the nutritional value of the co-products of bioethanol production for broilers and turkeys. Specifically, his research is providing data and practical recommendations for poultry about the energy value, nutrient digestibility and optimal inclusion rates for wheat- and corn-Distillers Dried Grains with Solubles (wheat-DDGS and corn-DDGS) produced in bioethanol plants in the United Kingdom.

The studies he is conducting here are designed for him to gain experience in Swine Nutrition.

Nathan Horn
Graduate Student (Ph.D.)
E-mail: nhorn@purdue.edu

Nathan received his B.S. and M.S. degrees from Purdue University in 2005 and 2008, respectively. His M.S. research focus was investigating the impact of dietary threonine on mucin production in broiler chicks and Pekin ducklings. Following his M.S. degree, Nathan was employed at JBS United (Sheridan, IN) for approximately four years. His responsibilities while at JBS United included management of nursery and mycotoxin research, nursery diet formulation, research intern management, and technical service. The focus of his Ph.D. will involve investigation of the impact of prebiotics and phytochemicals on monogastric species nutrient absorption and digestive physiology.

After receiving his B.S. and M.S. in Animal Science and Biotechnology from Seoul National University in 2002 and 2004, respectively, Changsu joined the monogastric animal nutrition laboratory of Dr. Adeola. For his Ph.D., his work is on amino acid nutrition. In mixed diets, the proportional quantities of digestible AA from each feed ingredient are added, and the sum represents the quantity of digestible AA in the diet because additivity of the digestible contents of each AA in individual feed ingredients is assumed when these ingredients are mixed together. Apparent and standardized ileal digestibility (AID and SID) of amino acids has been commonly used for diet formulation. However, assumption of additivity for AID has been questioned because of underestimation of AID for most AA in cereal grains. So, his research focus is on understanding the additivity and associative effect of digestibility of AA in diets for swine and poultry.

Ahmet Pekel
Visiting Scholar

Dr.Pekel received a veterinary degree from Ankara University, Turkey and a Ph.D. degree in Animal Nutrition from Istanbul University, Turkey. His research interests include evaluation of alternative feedstuffs for broiler chickens and laying hens.

Dr. Pekel will conduct research here until November 30, 2013 on energy, phosphorus, and amino acid values of camelina meal for broiler chickens.

Pengcheng 'Alan' Xue
Graduate Student (Ph.D.)

Pengcheng Xue joined Dr. Adeola's lab in the fall of 2011 as a Ph.D. student. He has already received his B.S. and M.S. degrees from China Agricultural University. His work is mainly about non-ruminant animal nutrition (swine and poultry), especially amino acid and phosphorus digestibility of feedstuffs.


Hengxiao Zhai

Hengxiao Zhai
Graduate Student (Ph.D.)

Hengxiao joined Dr. Adeola's lab in 2008 to pursue his Ph.D. His current research focuses on the application of commercial enzymes in grower and finisher pigs. Exogenous enzymes are designed to target the anti-nutritional components in high-fiber ingredients, potentially making those ingredients more valuable to the animals. Further down his Ph.D. work, he plans to further research work on the determination of the phosphorus requirement of the pigs. This is especially timely not only because of phosphorus is expensive but also because of the environmental concerns associated with phosphorus use in animal nutrition. To precisely measure the phosphorus requirement of the pig is both challenging and meaningful.
