68: Why Multiple Mycotoxins in the TMR Increase Dairy Herd Risk

Multiple mycotoxins in the TMR do not just add up. They multiply damage in dairy cows.In this episode of Ruminate This, Scott Zehr and Vice President of Nutrition Dr. Larry Roth connect their previous episode discussions and explain why multiple mycotoxins in the TMR create a multiplying negative effect in dairy cows rather than a simple additive one.They discuss how common toxins such as DON, fumonisin, T-2/HT-2, and zearalenone each remove a critical layer of biological protection. Even when individual toxin levels appear “safe,” combinations can lower the cow’s ability to defend herself, regulate intake, maintain rumen integrity, and support reproduction.The episode explores high-risk toxin pairings, early warning signs such as inconsistent intake, erratic manure, milk production plateaus, and reproductive challenges, and why multiple low-level mycotoxins are often more dangerous than a single high-level exposure.📈 Get the Guide for Mycotoxins Free🎧 Listen now on Apple Podcasts, Spotify or your favorite podcast platform 💬 Have thoughts or a story to share?
