Nick Gabler

Dr Nick Gabler

Associate Professor, Iowa State University

Dr Nicholas Gabler obtained his Bachelors of Agricultural Science from La Trobe University, Melbourne, Australia. In 2005, he received his Ph.D. degree in Animal nutrition and physiology also from La Trobe University. Upon completion of his Ph.D., he conducted postdoctoral research in the USA at both Purdue and Iowa State Universities. Here he worked on evaluating sources of n-3 fatty acids (docosahexaenoic acid and eicosapentaenoic acid) in nursery-finisher pig production and using the pig as a biomedical model. In 2008 he joined the Animal Science Department at ISU as an assistant professor in fundamental swine nutrition and metabolism. Presently, Dr Gabler has an active and diverse research program that focuses on understanding and improving swine feed efficiency, nutrition by health, and intestinal physiology of pigs. He utilized both basic and applied, cellular and whole animal approaches. His research program can be divided into four areas: (1) Understanding the physiology and molecular pathways that define feed efficiency differences in swine; (2) Gastrointestinal physiology (integrity and function) of swine; (3) Using the pig as a biomedical model or dual purpose research (livestock and human application); and (4) Understanding the impact of disease and poor health on metabolism, nutrient requirements and tissue accretion. This later research has been using enteric and respiratory pathogen challenge models to study how health challenges alter pig productivity and nutrition. He is also working on finding alternatives to sub-therapeutic antibiotic growth promotants. Over the last eight years, Dr Gabler has graduated six M.S. students and five Ph.D. students from his program. He has been active as an author and co-author and has published over 60 peer-reviewed journal articles and review papers. Further, he has published over 70 meeting abstracts at regional, national and international meetings since joining the faculty. His research is making important scientific contributions to swine production and science.

Anna Johnson

Dr Anna Johnson

Professor, Iowa State University

Dr Anna Johnson is a Professor in the Department of Animal Science at Iowa State University with a 50% research, 25% teaching and 25% extension appointment. Johnson earned her doctorate degree in animal welfare from Texas Tech University in Lubbock, Texas, her bachelor’s degree in animal science from Reading University and a master’s degree in applied animal behavior and animal welfare from University of Edinburgh. Dr. Johnson teaches both undergraduate and graduate level animal behavior and welfare classes. Johnson’s research interests include pig health, pain and euthanization, caretaker-pig interactions, on-farm assessments and audits and sow productive lifetime. Johnson serves as a resource for livestock industries’ by creating and delivering educational livestock welfare material for example Pork Quality Assurance Plus and the Common Swine Industry Audit. Johnson serves on numerous state, national and international committees. She is a professional reviewer for several leading welfare journals (Applied Animal Behaviour Science, Animal Welfare and Journal of Applied Animal Welfare Science). Prior to joining ISU, Dr. Johnson was the Director of Animal Welfare for the National Pork Board. Johnson developed and implemented Checkoff-funded swine welfare and welfare-related research within the Science & Technology Department. Johnson was instrumental in the formulation and launch of the Swine Welfare Assurance Program. Dr Johnson is active in the International Society for Applied Ethology and is a reviewer for international journals in the field of livestock behavior and welfare.

Billy Flowers

Dr Billy Flowers

Distinguished Professor, North Carolina State University

In 1987, he joined the faculty in the Animal Science Department at North Carolina State University where he currently is a William Neal Reynolds and Alumni Distinguished Professor with a teaching and research appointment. He teaches undergraduate, graduate, and veterinary classes in reproduction and swine management. His research program focuses on improving male and female fertility. Dr Flowers has published over 170 peer-reviewed journal articles and book chapters and more than 450 popular press / extension articles dealing with swine reproductive physiology and artificial insemination.

Christy Bratcher

Dr Christy Bratcher

Professor, Auburn University

Dr Christy Bratcher is a professor of meat science in the Department of Animal Sciences in the College of Agriculture at Auburn University. Bratcher investigates the safety of processed meats, pre- and post-harvest meat animal food safety, and consumer acceptance of niche market products. She is currently leading a USDA-funded project to identify gaps in food safety and security procedures among local and regional animal producers and processors who sell directly to consumers and farmers markets. The end goal is a certification program designed to give local and regional operators added credibility in the hopes of stimulating rural economies. Bratcher is also investigating novel ways to introduce both natural and synthetic antimicrobials as pre-processing technologies to reduce microbial load on the surface of meat. She teaches and mentors both undergraduate and graduate students, and has won several awards related to education. In 2018, she received the Leischuck Endowed Presidential Award for Excellence in Teaching, the highest teaching honor given by Auburn University. On the outreach side, her activities include helping processors throughout the state address issues related to food safety, processing, and business opportunities in meat as well as working with the Alabama Cattlemen’s Association and the Alabama Cooperative Extension System to deliver educational programs to chefs, students, and meat industry representatives. Bratcher is also director of the Auburn University Food Systems Institute, which provides an infrastructure for promoting interdisciplinary research, outreach, teaching, and training opportunities relating to food systems. The institute works with everyone from faculty in academia to food industry personnel and consumers in the general public. Prior to Auburn, Bratcher worked in the meat industry as food safety and quality assurance director at a meat company. She received both her bachelor’s and master’s degrees in animal science from the University of Florida before going on to earn her doctorate in animal science from the University of Missouri.
