79: Why Does a Clay Binder Firm Up Manure? The Science Behind Mycotoxin Binders

A dairy producer asked a simple question: "Every time I feed a clay binder, my cows' manure firms up. If it isn't binding the mycotoxins, why does that happen?" In this Letters from the Field episode, Scott Zehr and Dr. Larry Roth explore the science behind clay-based mycotoxin binders, manure consistency, gut health, and nutrient bioavailability. They explain why firmer manure doesn't always mean the underlying mycotoxin challenge has been addressed, review the research on how clay binders perform against common mycotoxins like DON (vomitoxin), aflatoxin, fumonisin, and zearalenone, and discuss an alternative strategy focused on protecting intestinal integrity rather than simply binding toxins. If you're looking to better understand what manure consistency is really telling you, this episode delivers practical, research-backed information for managing mycotoxin challenges. 🎧 Listen now on Apple Podcasts , Spotify or your favorite podcast platform 💬 Have thoughts or a story to share?

78: Rethinking Transition Cow Health

When dairy producers think about improving profitability, they often focus on the cow. But what if the biggest opportunity starts much earlier? We're excited to share this episode of The Dairy Podcast Show , where host Dr. Barry Bradford sits down with John Lawlor , dairy industry consultant, to discuss why forage quality, feed management, and system-wide thinking have a greater impact on profitability than many producers realize. From harvest decisions to feed efficiency and long-term herd performance, this conversation explores how seemingly small management choices can influence milk production, feed costs, and overall business success. In this episode: Why profitability begins before feed reaches the ration How forage quality drives feed efficiency The hidden costs of poor feed management Why system thinking improves dairy performance The importance of measuring what matters Common management decisions that quietly reduce profitability Building a more resilient dairy operation Practical ways to improve long-term return 💬 Have thoughts or a story to share?

76: Where Did the Protein Go?

A simple question from a nutritionist sparked one of the most thought-provoking conversations we've had on Ruminate This . If DON mycotoxins interfere with protein synthesis, how much milk protein could dairy cows be losing before clinical signs ever appear? In this Letters from the Field episode, Dr. Larry Roth explores the hidden cost of nutrient chaos. How mycotoxins can redirect nutrients away from production and toward defense, affecting rumen function, liver health, reproduction, immune function, and overall performance. If nutrients are being diverted from production to defense, what could that be costing your herd? 🎧 Listen now on Apple Podcasts , Spotify or your favorite podcast platform 💬 Have thoughts or a story to share?
