Cargill120The American Meat Science Association (AMSA) has announced Dr. Bradley Johnson as the recipient of the 2020 Distinguished Research Award.  The award was established in 1965 to recognize members with outstanding research contributions to the meat industry and is sponsored by Conagra Brands, Inc. Dr. Johnson will be honored on Thursday, August 6, 2020 at 3:30 p.m. (CST), during the Virtual 66th International Congress of Meat Science and Technology (ICoMST) and the AMSA 73rd Reciprocal Meat Conference (RMC) awards presentation.

Bradley JohnsonDr. Bradley J. Johnson, a native of Milbank, S.D., earned a bachelor’s degree in animal science from South Dakota State University. His master’s degree in animal science and doctorate in animal science are from the University of Minnesota. Johnson is currently the Gordon W. Davis Regent’s Chair in Meat Science and Muscle Biology and a professor in the College of Agricultural Sciences and Natural Resources’ Department of Animal and Food Sciences at Texas Tech University. Johnson has been in this position since June 1, 2008. Prior to coming to Texas Tech, he was a muscle growth and development assistant and associate professor with the Department of Animal Sciences & Industry at Kansas State University from October 2000 to June 2008. Additionally, Johnson worked as an Extension Ruminant Nutrition and Beef Feedlot Specialist and was an assistant professor with the Department of Animal and Range Sciences at South Dakota State University August 1997 to October 2000. Johnson is internationally known as an outstanding researcher and has served and represented AMSA on many occasions in the scientific community. In 2018, Dr. Johnson was recognized by the University of Minnesota as an outstanding alumnus for his contributions to science and education.

Johnson has over 25 years of research experience working with veterinary drugs used for global meat-animal production. He has published 116 peer-reviewed journal articles, 12 invited reviews or book chapters, and has advised more than 70 graduate and postdoctoral students. The majority of Johnson’s research over this time has involved evaluating the mechanism of action and physiology of two classes of veterinary drugs approved for meat production, steroidal implants and β-adrenergic agonists. Many models have been used by Johnson to evaluate the mode of action of both of these veterinary drugs including cell culture, tissue explant and in vivo experiments. Johnson was the first to evaluate the combined trenbolone acetate/estradiol 17β steroidal implant for beef cattle in the United States. Results from these experiments defined the mechanism of these compounds on postnatal muscle growth, and subsequently, the metabolism of the parent compounds as they were excreted from the target animal. In addition, his laboratory also has worked extensively on the mechanism of action of β-adrenergic agonists at both the skeletal muscle and adipose tissue level. More recently, he has been asked to address the proposed metabolism of these compounds as it relates to potential residues in edible tissues.  Specifically, he has played a pivotal role in anti-doping cases involving meat consumption.

International audiences and governments have sought Johnson’s expertise in this area. In 2010, Johnson worked with the feedlot industry in Indonesia to address the use of growth promotants in beef cattle production. The following year, Johnson was engaged in β- adrenergic agonist research in South Korea with their native Hanwoo cattle. Johnson was involved in the introduction of β-adrenergic agonists to the Brazilian feedlot industry in August 2012. Additionally, Johnson has worked with Egyptian scientists (2015-current) to increase their knowledge of the mechanism of action and metabolism of veterinary drugs such as steroidal implants and β-adrenergic agonists. In 2017 Johnson was appointed to the Joint (FAO/WHO) Expert Committee of Food Additives (JECFA) with expertise on the veterinary drug residue platform. This committee serves as scientific advisors for the establishment of the global food safety standards of Codex Alimentarius and other global groups.

Johnson has been involved in research in the area of marbling development of beef cattle.  He has collaborated for many years with Dr. Stephen Smith at Texas A&M University in College Station.  They have interest in understanding the role of GPR41 and 43 receptors and oleic acid in adipose tissue development of beef cattle.

Outside of his research, Johnson enjoys spending time with his family.  His wife, Jolene, and he have been married 30 years and have three children, Kaitlin, Nathan and Evan.  They all reside in Lubbock, Texas
