Short Bio

Dr. Wilmer J. Pacheco is originally from Honduras and earned his Bachelor of Science degree in Food Science from the Pan-American School of Agriculture (Zamorano) in 2005. Following graduation, he joined Murphy Brown, LLC, as part of a feed mill manager training program, where he oversaw the production of approximately 10,000 tons of pelleted feed per week. This early industry experience shaped his long-term focus on the integration of feed manufacturing and animal nutrition. In 2009, Dr. Pacheco was awarded a competitive scholarship to pursue graduate studies at North Carolina State University’s Department of Poultry Science. He earned both a Master of Science in Poultry Science and a Ph.D. in Physiology and Nutrition, developing expertise in digestive physiology, nutrient utilization, and feed processing. Dr. Pacheco currently serves as Associate Professor and Extension Specialist in the Department of Poultry Science at Auburn University. His research program focuses on the interrelationships between feed processing and nutrition and their combined effects on broiler performance, feed efficiency, pellet quality, and production economics. His work bridges fundamental physiology with applied feed mill management to generate science-based, industry-relevant solutions. He is the lead or co-author of 54 peer-reviewed scientific publications and more than 100 industry articles, primarily published in Feedstuffs, one of the leading animal agriculture news sources in the United States. Dr. Pacheco has delivered more than 300 invited presentations in 27 countries and has served as chair or committee member on 38 graduate student committees. He has also mentored 31 visiting scholars representing 12 countries. In collaboration with the U.S. Soybean Export Council (USSEC), Dr. Pacheco has developed and delivered both online and in-person training programs in feed manufacturing and poultry production. These programs have benefited nearly 20,000 professionals across more than 20 countries in Latin America, the Middle East, North Africa, and Southeast Asia, contributing to global workforce development and improved feed production efficiency.

Professional Experience

Dr. Wilmer J. Pacheco serves as Associate Professor and Extension Specialist in the Department of Poultry Science at Auburn University. His program integrates applied research, extension, and teaching with a strong emphasis on feed manufacturing, poultry nutrition, and digestive physiology. His work focuses on the interrelationship between feed processing and nutrient utilization and their combined effects on broiler performance, feed efficiency, and industry sustainability.

Prior to entering academia, Dr. Pacheco participated in a feed mill management training program overseeing the production of approximately 10,000 tons of pelleted feed per week. This experience provided foundational expertise in commercial feed manufacturing operations, quality assurance, and plant efficiency, which continues to inform his applied research and extension programming.

Research

In the last 5 years, Dr. Pacheco has published more than 40 peer-reviewed research articles in leading journals, including Journal of Applied Poultry Research and Poultry Science, addressing critical feed processing variables that directly influence poultry performance and manufacturing efficiency. Other research areas include conditioning temperature retention time effects on pellet quality and nutrient stability, feed form interactions and their impact on broiler performance, particle size and its influence on nutrient digestibility and broiler performance, thermal processing strategies for pathogen mitigation, among others. 

These studies provide the scientific foundation for his extension programing and industry recommendations. Findings from this research have been translated into workshop content and published extension materials, ensuring that commercial feed manufacturing decisions are grounded in validated data rather than anecdotal practice. By maintaining a strong research-to-extension pipeline, Dr. Pacheco enhances adoption rate of his recommendations, strengthening industry confidence in process modifications and performance optimization strategies.

Extension Experience

Dr. Wilmer J. Pacheco leads a nationally and internationally recognized extension program focused on strengthening feed manufacturing systems to enhance poultry production efficiency, regulatory compliance, product quality, and economic sustainability. His work operates at the critical intersection of feed processing, nutrition, and applied physiology where manufacturing decisions directly influence animal performance and financial outcomes.

Feed represents approximately 65 to 70% of live production cost in broiler operations. In integrated poultry systems producing millions of birds annually, even modest improvements in feed conversion ratio (FCR), pellet quality, particle size uniformity, or shrink control translate into substantial economic returns. Recognizing this leverage point, Dr. Pacheco’s extension program targets feed manufacturing as a high-impact control node within the poultry production chain.

Dr. Pacheco’s approach integrates applied research, regulatory leadership, and hands-on mill diagnostics to produce measurable and durable improvements in commercial operations. His extension programming emphasizes implementation and operational validation not simply knowledge dissemination. By combining scientific rigor with commercial feed mill experience, he delivers recommendations that are technically sound, economically realistic, and sustainable in high-throughput environments.
