Summer heat stress in dairy cattle is about far more than fans and sprinklers. In this episode of Ruminate This, Scott Zehr and Dr. Larry Roth discuss the hidden biological effects of heat stress in dairy cows, including inflammation, leaky gut, oxidative stress, altered blood flow, and immune disruption. They also explain why heat stress should be viewed as an inflammation challenge rather than simply a temperature problem.

The episode also explores how DTX™ with Livox uses probiotic technology and plant actives like curcumin, naringen, and carnosic acid to support dairy cows during periods of heat stress. Learn how internal biological support may help cows better withstand the stacked environmental insults of summer while supporting health, performance, and resilience.

Most dairy conversations treat heat stress in dairy cows as the primary problem.
But what if it is not the root cause. What if it is the multiplier?

In episode 72 of Ruminate This, Scott and Dr. Larry Roth explore a different way to think about dairy heat stress. Not as an isolated challenge, but as something that amplifies underlying issues like mycotoxins, reduced dry matter intake, and marginal nutrition.

They walk through how stacked stress impacts gut health, liver function, and milk production, often long before you see changes in the tank.

If you are a dairy producer, nutritionist, or consultant, this episode will help you better understand how to manage heat stress and protect cow performance during high-risk periods.

In this episode of Ruminate This with Agrarian Solutions, host Scott Zehr continues the conversation with Joe Lawrence of Cornell Pro-Dairy, shifting from forage strategy to what matters most right now: return on investment.

With milk prices under pressure and input costs still elevated, the margin for error is slim. This episode explores the real economics behind forage decisions—and how small missteps can erode profitability.

Scott and Joe discuss:

• Why short-term decisions often come at a long-term cost
• The difference between growing tons and feeding usable tons
• How forage shrink can act like someone stealing 25% of your bank account if left unmanaged
• Why securing high-quality forage for lactating cows beats scrambling to replace it later
• The risk of “busy” decisions that don’t deliver financial returns

This conversation redefines forage management as one of the most controllable and impactful financial levers on a dairy operation.

If you're looking to navigate tight margins, reduce purchased feed, and make more confident decisions under pressure, this is a must-listen.

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 yield
• How harvest timing, not hybrid or variety, drives forage quality
• The hidden cost of shrink and poor storage management on milk production
• Why small grains and cover crops should be strategic tools, not backup plans
• The difference between maximizing tons harvested vs. tons fed

They 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.

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.

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.

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.
