Dr. Todd Callaway: Ruminant Microbiology in Management | Ep. 48
Feeding ruminants goes beyond just nourishing the animal itself. It heavily revolves around supporting the ruminal microbiota. The role of microorganisms in ruminants is crucial for obtaining the necessary nutrients and ensuring optimal performance. Dr. Todd Callaway, an expert from the University of Georgia, delves into the intricate microbial environment present in cattle's digestive system in this episode. His research journey focuses on understanding the functionalities of the gut microbiota in cattle nutrition. Here, he explores the complexities of the cattle gastrointestinal tract and its implications for food safety and production efficiency.
“Over the years, we have invested significant effort in studying the typical carriage of pathogens, distinguishing what is considered normal from what isn't.” - Dr. Todd Callaway
