NIFA awards five-year grant to animal science faculty
KNOXVILLE, Tenn. – Beef production depends heavily on how efficiently cattle convert feed into energy. By winning a federal award, University of Tennessee Institute of Agriculture researchers are studying this process at the genetic, cellular and microbial levels.
The team, led by Phillip Myer, associate professor of animal science and UT AgResearch Faculty Fellow, includes department colleagues Jonathan Beever, professor, and Troy Rowan, assistant professor and Extension specialist. They secured a five-year $650,000 grant from the USDA National Institute of Food and Agriculture, which awarded $10 million to 19 projects to improve animal nutrition, growth and lactation.
The researchers are focusing on specific microbes in the rumen, the stomach of cattle, and how they interact with the animal’s tissue to influence how nutrients are absorbed and used. The study will identify cell types in the rumen wall, characterize the microbes and their functions, and determine the genetic factors that influence how this system works.
“Our previous research showed that microbes in the rumen are influenced by the animal’s genetics and play an important role in how efficiently cattle use feed. This project is about connecting those pieces—genes, cells and microbes—to uncover the biology behind efficiency, which is essential for developing practical, meaningful improvements that benefit both producers and the future of beef production,” Myer said.
Myer’s research focuses on gut microbiology of beef cattle while Beever is director of the UTIA Genomics Center for the Advancement of Agriculture and Rowan studies genetic improvement of traits such as metabolic efficiency.
As a result of this study, the researchers will provide new knowledge that will be used to improve breeding strategies and develop microbial interventions to increase feed efficiency in beef cattle. Results will be shared through educational programming and with industry partners and stakeholder groups.
