The Dairy Podcast Show Dr. Antonio Faciola: Rumen Microbiology Insights | Ep. 10
The rumen is probably the most important machinery that drives cows’ production and health, yet there remains a lot that is unknown of how the rumen actually works. Mimicking the rumen environment in in vitro systems has been an important tool to understand rumen microbiology. Dr. Antonio Faciola, our guest on today’s episode, replicates the rumen environment in systems called fermenters. He and his group strive for a better understanding of how rumen microbiology works. He talks about the rumen microbes’ effects on methane production and possible effects in immune response in dairy cows.
“We know very little of the microorganisms that are present in the rumen; there are several that we simply don't know” - Dr. Antonio Faciola

Dr. Antonio Faciola started his career in Brazil and received his Ph.D from the University of Wisconsin. Further, he received his Post-doctorate at Cornell University and ARS – USDA. Currently, he is an Associate Professor of Livestock Nutrition in the Department of Animal Sciences at the University of Florida. His overall research goal is to further our understanding of ruminant nutrition, to improve the efficiency of nutrient use as a means to enhance animal production and minimize negative environmental impacts.
