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.

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.

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.

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 fermentation
• Push undigested nutrients “down the river” into the hindgut, leading to undesired hindgut fermentation
• Create signs that look like acidosis, when the real issue may be hindgut acidosis driven by poor rumen breakdown
• Weaken gut barrier integrity, increasing permeability and contributing to leaky gut
• Trigger immune activation and force nutrient reallocation, pulling glucose and energy away from milk and reproduction to support inflammation control
• Compound 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.

This is the final episode of the year for Ruminate This, and we’re closing it out with a “best of” reflection on five episodes that continue to matter on dairy farms today.

In this year-end episode, Scott Zehr revisits some of the most impactful conversations on dairy nutrition, calf health, transition cow management, gut health, and mycotoxin control, and explains why these topics continue to influence herd performance and profitability long after the episode airs.

Whether you’re revisiting these discussions or hearing them for the first time, this recap highlights practical, on-farm insights that help producers and nutritionists reduce risk, improve efficiency, and make better decisions across every stage of production.

Featured topics include:

• Gut health and digestive integrity and why protecting the rumen and liver is foundational to performance
• Calf health from day one and winning the battle of the gut during the milk-feeding phase
• Colostrum management, including quality, quantity, and why management matters more than band-aid solutions
• Transition cow nutrition and why preventing milk fever alone is not enough
• Proactive mycotoxin testing and how DON, zearalenone, and fumonisin quietly impact herd health

If you’re focused on raising healthier calves, supporting smoother transitions, protecting reproduction, and improving long-term dairy profitability, this episode brings together the conversations worth revisiting.

Everyone talks about “culture” on dairies, but for calves, culture quietly determines which calves grow into healthy, high-performing cows and which struggle.

In this episode, Scott explores how Agrarian Solutions’ RISE core values, Relational, Integrity, Strategic, and Excellence, shape real-world calf management, not just posters in the office.

Through examples from three dairy farms, Scott demonstrates why the same facilities, nutrition, and SOPs can produce drastically different results:

• Farm A: Two shifts, same protocols, with wildly different outcomes because attention to calves matters.
• Farm B: Intentional hiring and team alignment drives uniform, resilient dairy calves that more than double birth weight.
• Farm C: No new equipment or formulas. They focused on people, and calf health problems disappeared.

Explore how to apply RISE on your dairy farm by seeing quiet signals, sticking to protocols, and refusing mediocrity. Plus, learn why pre-weaning growth predicts lifetime milk production and how excellence spreads through dairy farm culture.

What do you do when the cows look perfectly fine but performance keeps drifting? In this episode of Ruminate This, Scott Zehr breaks down the quiet, hard-to-detect issue plaguing many dairy herds: subtle biological stress, especially from low-level mycotoxins that rarely show up on a single feed test but can dramatically impact herd performance.

Scott explains how cows can look visually healthy while quietly battling stress that affects reproduction, rumination, immune function, intakes, components, manure consistency, and overall milk production.

In this episode, you’ll learn:

• Why cows “whisper” their symptoms instead of crashing.
• How low/medium DON, Zearalenone, T-2, and Fumonisin levels still cause major damage.
• Why mycotoxin tests often mislead (uneven distribution + sample variability).
• The real signs of toxin pressure: weak heats, cysts, SCC drift, soft milk, inconsistent manure, fluctuating intakes.
• Why patterns matter more than single data points.
• How to use Agrarian’s DTX Decision Chart to identify immune suppression.
• A real case where cows looked totally fine until toxin correction turned the herd around.
• Exactly what to review in your last 90 days of herd data to spot hidden stress before it becomes costly.

If your cows look “fine” but your numbers don’t, this episode will give you the clarity you’ve been searching for.

Today’s dairy herds are facing a new class of mycotoxin challenges that traditional binders weren’t designed to address. In this episode, Scott Zehr explains why today’s most common mycotoxins (DON, Zearalenone, T2/HT2, Fumonisin) don’t respond to the same binder strategies developed for aflatoxin.

Instead of being bound in the gut, these toxins are absorbed into the bloodstream and suppress the cow’s immune system. The result: cows that look fine, but fall short on milk, heats, and conception.

Scott outlines how biological solutions like DTX™ support immune function, gut integrity, and nutrient allocation, including a +2.5 lb milk response in a large commercial trial. If you’ve ever walked pens and thought, “The cows look okay… but something feels off,” this episode connects the dots.
