AMSA Announces Symposium Speakers on Pre-Harvest Factors Influencing the Biology of Skeletal Muscle as Food 

Kearney, MO. May 24, 2021 – The American Meat Science Association (AMSA) is pleased to announce, Dr. Bradley Johnson, Dr. Gale Strasburg, and Dr. Amanda Blair will be the featured speakers in the symposium entitled “Pre-Harvest Factors Influencing the Biology of Skeletal Muscle as Food” on Monday, August 16, 2021, during the 74th AMSA Reciprocal Meat Conference (RMC) at the Grand Sierra Resort and Casino in Reno, Nevada, USA. This session will be sponsored by Texas Tech University. 

Gordon W. Davis, Regent’s Chair in Meat Science and Muscle Biology and Professor at Texas Tech University, Dr. Bradley Johnson will start this technical session off with an overview of the “Impact of Growth Promotion on Meat Quality Characteristics.” During this talk Dr. Johnson will discuss the impact of various growth promotion techniques on factors affecting meat quality traits such as tenderness, juiciness, and flavor. Specifically, a discussion on the mode of action of specific growth promotants on skeletal muscle fiber hypertrophy and marbling development will be shared.

Various studies suggest that early exposure of hatchlings to heat or cold stress has significant long-term consequences for bird growth and meat quality. In the second presentation of this technical session Dr. Gale Strasburg, Professor of Food Science and Human Nutrition at Michigan State University will review our current understanding of how thermal challenge affects poultry muscle development in a talk titled “Effects of Early Thermal Challenge on Poultry Muscle Growth, Development, and Meat Quality.” Dr. Strasburg will cover the importance of timing of the stress, and possible strategies for mitigation to maintain consistent, efficient, and high-quality meat products.        

A presentation from Dr. Amanda Blair, Professor of Animal Science and Meat Science Extension Specialist at South Dakota State University over “Maternal Nutrition and Meat Quality of Progeny” will close out this technical session.  Dr. Blair will share with attendees how the concept of fetal programming is based on the idea that nutritional status and environmental conditions encountered by the dam during pregnancy can have lifetime impacts on her offspring.  These changes in the gestational environment have been shown to influence fetal development and subsequent growth performance, carcass composition, and meat quality characteristics. In her presentation, Dr. Blair will explore the concept of fetal programming, provide an overview of research in beef cattle, and discuss the influence of maternal nutrition on offspring carcass composition and meat quality.

AMSA is an organization recognized for its unmatched competence and commitment to attracting and developing meat industry leaders and providing science-based meat research and information. For more information, please visit www.meatscience.org/rmc or contact Deidrea Mabry 1-800-517-AMSA ext. 12.
