Phillip R Myer
Specialization: Rumen Microbiology
The nutritional status of beef cattle and other ruminants is influenced by many factors, including diet, management, host genetics, and the diverse symbiotic microbiota colonizing the gastrointestinal tract (GIT). Overall, nutrition is determined by a complex interplay of these factors. For example, host genetics may influence the diversity and content of the GIT microbiome, which in turn may affect the efficiency of feed utilization. Additionally, the type and volume of feedstuffs consumed play a significant role in supplying nutrients to these GIT microbes, affecting the compounds they produce and, ultimately, the nutrients absorbed by the animal. By examining each of these key factors, from diet to microbiota, we gain a more comprehensive understanding of ruminant nutrition. This understanding has broad implications, influencing livestock production methods, resource consumption, and the overall sustainability of agricultural operations.
Dr. Myer's research program is primarily focused on the 1) microbiological and molecular mechanisms explaining differences in feed efficiency, enteric emissions, and overall nutrition of grazing beef cattle, and 2) development of the rumen microbiome and how it impacts the growth of beef cattle. These research objectives are pursued through a range of strategies that investigate the connections among microbial communities within the GIT and factors such as diet, management, and the genetics of the host animals.
