MSC 9418Building/Office: Agriculture (AGR) 117 Slot Number: 9
Dr. Oscar Tejeda is originally from Comayagua, Honduras. He received his Bachelor’s in agriculture with an emphasis in animal science from Zamorano University, Honduras in 2016. Additionally, he completed an internship at NC State University in 2016 where he worked with different poultry species including turkeys, broiler breeders, broilers chickens, and laying hens. After completing his Bachelor’s degree, he started his Master’s degree in poultry physiology at Auburn University which he completed in 2018. His Master’s was focused on the effects of management and nutritional practices on the modulation of myogenic stem cell populations, and muscle accretion. He obtained a Doctor of Philosophy (Ph.D.) in poultry nutrition from the University of Georgia (in 2021) that was focused on the effect of dietary fibrous components, dietary metabolites, and feed additives (i.e. enzymes, probiotics) on the modulation of intestinal morphology, nutrient metabolism, and gene expression of nutrient transporters.
