概要
In this episode of The Dairy Health Blackbelt Podcast, Dr. Dave Renaud, Associate Professor at the University of Guelph and veterinary epidemiologist, discusses antibiotic use in treating calf diarrhea. He shares research showing that blanket antibiotic therapy at the onset of diarrhea can reduce performance and increase health risks. Dr. Renaud also explains selective treatment, supportive care, and practical strategies to improve calf health outcomes. Listen now on all major platforms!
"Disruption of the gut microbiota during diarrhea, followed by antibiotic administration, may worsen dysbiosis and delay recovery."
Meet the guest: Dr. Dave Renaud earned a PhD in Epidemiology and a DVM from the University of Guelph. As an Associate Professor in dairy cattle health and veterinary epidemiology, his research focuses on disease prevention, calf welfare, and antimicrobial stewardship. He works closely with producers to apply data-driven solutions that improve herd health and productivity.
