75: Dairy Reproduction & Mycotoxins: Hidden Threats to Pregnancy Success

How much are mycotoxins costing your dairy operation? Our own Dr. Larry Roth, Vice President of Nutrition at Agrarian Solutions and frequent guest of the Ruminate This podcast recently presented at the Wisenetix Dairy Feed Additive Summit. In the webinar, Dr. Larry Roth and host Dr. Todd Callaway discuss how the impact of mycotoxins extends far beyond feed quality concerns. From gut integrity and immune function to nutrient allocation, follicle development, and conception rates, they examine the biological and economic consequences mycotoxins can have on dairy operations. Key topics covered include: • What mycotoxins are and how they develop in feedstuffs • The most common mycotoxins affecting North American dairies, including DON, Zearalenone, T-2, Fumonisin, and Aflatoxin • Why multiple mycotoxins are increasingly common in modern dairy production • How mycotoxins damage gut integrity and increase nutrient demands on the immune system • The relationship between nutrient allocation, follicular development, and reproductive success • Research evaluating traditional mycotoxin binders and their limitations • Independent field trial results demonstrating improved pregnancy rates when using DTX™ technology from Agrarian Solutions • Practical recommendations for mycotoxin testing and mitigation strategies Dr. Roth also reviews data from a large commercial dairy trial involving more than 900 cows, highlighting significant improvements in pregnancies per service for both artificial insemination and embryo transfer programs. Whether you're a dairy producer, nutritionist, veterinarian, or consultant, this presentation provides valuable insights into protecting herd performance and maximizing reproductive efficiency in the face of mycotoxin challenges. 💬 Have thoughts or a story to share?

73: Heat Stress and Inflammation in Dairy Cows

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.  🎧 Listen now on Apple Podcasts [https://bit.ly/RuminateThisApplePodcasts], Spotify [https://spoti.fi/4jUM87g]or your favorite podcast platform [https://bit.ly/RuminateThisPodcast]  💬 Have thoughts or a story to share?
