    70: Forage Quality Decisions That Drive Dairy Profitability

    In this episode of Ruminate This with Agrarian Solutions, host Scott Zehr sits down with Joe Lawrence of Cornell Pro-Dairy to discuss one of the most critical and often underestimated drivers of dairy profitability: forage quality. As first cutting approaches, this conversation focuses on the real-world decisions dairy producers are making right now that will impact milk production, feed efficiency, and herd performance for the entire year. From harvest timing and equipment readiness to storage management and crop strategy, Scott and Joe go beyond theory and into practical application. In this episode, you’ll learn: Why first cutting can account for 40–50% of total forage yieldHow harvest timing, not hybrid or variety, drives forage qualityThe hidden cost of shrink and poor storage management on milk productionWhy small grains and cover crops should be strategic tools, not backup plansThe difference between maximizing tons harvested vs. tons fedThey also challenge assumptions around continuous corn systems, double cropping, and aligning agronomic decisions with labor and logistics on today’s dairy farms. Whether you're a dairy producer, nutritionist, agronomist, or industry professional, this episode delivers value to help you get more from your forage program. Because what goes into the bunk today determines what ends up in the tank tomorrow. 🎧 Listen now on Apple Podcasts, Spotify or your favorite podcast platform  💬 Have thoughts or a story to share?

    69: Cow Reproduction Is Improving… So Why Aren’t Heifers?

    Dairy cow reproduction has improved significantly over the past decade, but virgin heifer reproduction has remained relatively flat. Why? In this episode of Ruminate This, Scott Zehr explores whether mycotoxins in virgin heifer TMRs could be quietly influencing heifer conception rates and dairy fertility. While dairies have made major advances in reproductive protocols, genetics, and technology, heifers may represent one of the biggest remaining opportunities for improvement. Scott explores why heifer diets are often among the least-tested rations on the farm, how multiple mycotoxins can affect immune function and hormone signaling, and why young animals may actually have less margin for error than many assume. If heifer fertility has plateaued, maybe it isn’t a protocol problem at all, maybe it’s a fundamentals problem. 🎧 Listen now on Apple Podcasts, Spotify or your favorite podcast platform  💬 Have thoughts or a story to share?

    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?

    67: T-2 Exposure and Hemorrhagic Bowel Syndrome in Dairy

    T-2 mycotoxin, often called the assassin toxin, is one of the most aggressive and overlooked feed risks in dairy production. In this episode of Ruminate This, Dr. Larry Roth explains how T-2 disrupts protein synthesis, damages the rumen and intestines, and creates serious health challenges at levels as low as 75 ppb. They connect T-2 exposure to Hemorrhagic Bowel Syndrome (HBS), gut integrity breakdown, and increased risk from Clostridium perfringens. The discussion also covers feed risks, including refusal management, TMR variability, and why passing down feed can increase mycotoxin exposure. 🎧 Listen now on Apple Podcasts, Spotify or your favorite podcast platform  💬 Have thoughts or a story to share?

    66: Inconsistent Herd Performance? Take A Closer Look at Fumonisin

    Fumonisin is one of the most overlooked mycotoxins in dairy production, and its impact goes beyond immune suppression. In this episode, Dr. Larry Roth explains how fumonisin disrupts cell-to-cell communication in the gut (often called quorum sensing), which plays a critical role in gut integrity, immune function, liver health, and respiratory resilience. Learn why this mycotoxin is increasingly more common, why many binders fall short, and how targeted testing and smarter mitigation can help explain inconsistent herd performance. 🎧 Listen now on Apple Podcasts, Spotify or your favorite podcast platform  💬 Have thoughts or a story to share?

    65: Beyond Fertility | Zearalenone’s Impact on Herd Health

    Zeralanone is often labeled a reproductive mycotoxin, but that barely scratches the surface. This reproductive mycotoxin, is an estrogen imposter that disrupts fertility, immunity, liver function, and overall metabolic stability. In this episode, Dr. Larry Roth explains why zearalenone is fat-soluble, how it can be stored and released during post-calving fat mobilization, and why its metabolites may be even more damaging than the parent toxin. Learn how it contributes to cystic ovaries, early embryonic loss, cows showing heat signs while pregnant, and inconsistent reproduction, as well as why some traditional binders can make things worse. If pregnancy rates aren’t matching expectations, this episode shows why zearalenone could be the hidden disruptor and how targeted protection like DTX helps prevent absorption before damage occurs. 🎧 Listen now on Apple Podcasts, Spotify or your favorite podcast platform  💬 Have thoughts or a story to share?

    64: How DON Mycotoxin Slows the Rumen and Erodes Dairy Performance

    In this episode of Ruminate This, Scott Zehr is joined by Dr. Larry Roth (VP of Nutrition, Agrarian Solutions) for a discussion about DON (deoxynivalenol/vomitoxin)—one of the most common and most misunderstood mycotoxins in dairy rations. Rather than causing an obvious crash every time, DON often works like a “pause button” on rumen microbes. It doesn’t necessarily kill bacteria, it slows microbial function and disrupts fermentation, reducing the cow’s ability to convert the TMR into energy and microbial protein. The result can be a quiet, cascading problem: lower feed efficiency, reduced intake, erratic manure, and performance erosion that shows up long after the damage begins. Scott and Larry discuss how DON can: Disrupt rumen microbial balance by interfering with protein synthesis and slowing fermentationPush undigested nutrients “down the river” into the hindgut, leading to undesired hindgut fermentationCreate signs that look like acidosis, when the real issue may be hindgut acidosis driven by poor rumen breakdownWeaken gut barrier integrity, increasing permeability and contributing to leaky gutTrigger immune activation and force nutrient reallocation, pulling glucose and energy away from milk and reproduction to support inflammation controlCompound other stressors, making DON a major player in stacked inflammation They also discuss why the same DON ppm level can hit two herds very differently, and why ongoing mycotoxin testing can help connect the dots before a slow decline turns into a full-blown crisis. If you’ve ever wondered, “Is this really rumen acidosis… or something else?” This episode will change how you diagnose digestive, immune, and performance problems in high-producing dairy cows. 🎧 Listen now on Apple Podcasts, Spotify or your favorite podcast platform  💬 Have thoughts or a story to share?
