• Avian Influenza's Leap from Poultry to Cattle

  On this episode of Unplucked, host Andy Vance sits down with Dr. Scott Kenney of The Ohio State University to unpack how highly pathogenic avian influenza appeared in dairy cattle and what that means for poultry producers. Dr. Kenney explains the virology in plain language, from receptor binding and reassortment to why certain tissues act like virus factories. He shares results from high-containment studies showing that intranasal exposure produced limited disease in cows, while direct exposure of the mammary gland led to severe illness and extremely high virus levels in milk, and he connects those findings to practical risks in milking parlors and waste-milk handling.   The conversation moves from lab to barn with clear takeaways on biosecurity and surveillance, including why pasteurizing waste milk and tightening traffic in and out of milking areas can reduce cross-species transmission risk. Dr. Kenney also frames the situation through a One Health lens, discussing how to monitor for mammalian adaptation, what producers should watch as migration season approaches, and how vaccines and antivirals fit into preparedness for animals and people.   Legal: The information provided in this episode of Unplucked is for informational and educational purposes only and should not be considered professional advice.

• Can We Remove Inorganic Phosphorus? The Future of Poultry Diets with Phytase Innovation

  In this episode of Unplucked, host Andy Vance explores the cutting edge of poultry nutrition and feed innovation, live from the Poultry Science Association’s annual meeting. Andy talks with Dr. Emma Song, Global Technical Director at Sunhy Biology, about her latest research into phytase and its potential to completely replace inorganic phosphorus in poultry diets. Dr. Song shares insights from her presentations at the conference, detailing how advanced phytase enzymes are making more phosphorus available to birds, improving feed efficiency, and significantly reducing feed costs without sacrificing animal health or performance.   The discussion moves beyond broilers, as Dr. Song outlines the next steps in researching phytase application in turkeys and layers, and what it could mean for the broader industry. Andy is also joined by Matt Einarson, Vice President of Sales and Business Development at SAM Nutrition and Nexus powered by SAM. Matt discusses the company’s sustainability-driven approach to novel feed additives and the importance of scientific partnerships with universities and researchers to drive true innovation. Together, they talk about the challenges and opportunities facing poultry producers today, from global supply pressures to the need for more sustainable, efficient, and cost-effective nutrition strategies.   Whether you are interested in new enzyme technologies, removing inorganic phosphorus, or the future of sustainable poultry production, this episode delivers a thought-provoking look at the science and strategy shaping tomorrow’s poultry diets.   Legal: The information provided in this episode of Unplucked is for informational and educational purposes only and should not be considered professional advice.

• Unlocking Better Hatchability: The Impact of Micronutrients in Poultry Breeder Diets

  On this episode of Unplucked, host Andy Vance speaks with Dr. Mercedes Vazquez-Añon, Novus Senior Director of Strategic Initiatives and Accounts, to explore a challenge facing poultry producers worldwide: declining broiler hatchability rates. Recorded at the Poultry Science Association’s annual meeting, this conversation dives into how nutrition, especially micronutrients and trace minerals, plays a critical role in breeder fertility, embryonic development, and the quality of day-old chicks.   Dr. Vazquez-Añon explains how decades of genetic progress have improved feed efficiency and growth rates in broilers, but sometimes at the expense of fertility and reproductive health in breeders. The discussion highlights the often-overlooked importance of micronutrients like zinc, copper, and manganese, and why a more precise, science-based approach to mineral nutrition can help optimize skeletal and reproductive development from the pullet phase onward. Listeners will learn why a “more is better” approach to minerals can backfire, and how rethinking mineral balance is key to supporting better eggshell quality, chick health, and overall hatchability.   The episode also explores how evolving genetic lines and industry challenges, from avian influenza to rising economic pressures, make every fertile egg count more than ever. Dr. Vazquez-Añon offers actionable insights for nutritionists and producers, emphasizing the value of early intervention, precision feeding, and maternal nutrition strategies that give chicks the best possible start.   If you’re involved in poultry production, animal nutrition, or just curious about the science behind food production, this episode offers practical information and forward-thinking perspectives on how nutrition can help reverse the hatchability decline and drive sustainable success in the poultry industry.   Legal: The information provided in this episode of Unplucked is for informational and educational purposes only and should not be considered professional advice.

• Strong Animals, Strong Systems: Exploring Sustainability and Storytelling in Animal Agriculture

  On this episode of Unplucked, host Andy Vance sits down with Dr. Mark Lyons, president and CEO of Alltech, for an in-depth conversation about the future of food, the realities of animal agriculture, and the importance of connecting scientific progress with compelling storytelling. Recorded live at the Poultry Science Association’s annual meeting, their discussion takes listeners beyond the world of poultry to examine how cattle, culture, and the next generation of scientists are all part of creating a more sustainable food system.   Dr. Lyons shares the inspiration and vision behind A World Without Cows, a documentary film that explores the essential role of cattle in food security, nutrition, and environmental sustainability. The film was screened at the annual meeting and takes viewers around the world, sharing stories from farmers and communities whose lives are intricately connected to livestock. If you want to see more, you can watch the documentary and explore additional stories at https://worldwithoutcows.com.   The conversation also touches on the launch of Planet of Plenty, a company created by Dr. Lyons to further support initiatives that highlight innovation and optimism in agriculture. Andy and Mark dive into the challenges of communicating complex science to a broad audience and discuss why emotion and narrative are just as important as facts and data. They reflect on how food production and sustainability look very different depending on geography, culture, and local resources, and why it is so important to tell authentic, diverse stories from around the globe. The episode highlights the optimism and curiosity needed to lead in a rapidly changing agricultural landscape, and how true collaboration across disciplines, industries, and continents will shape the future of animal agriculture for years to come.   If you’re interested in how science, leadership, and storytelling intersect to shape our global food system, this episode offers insights, inspiration, and a fresh perspective on the stories that matter most in agriculture today.   Legal: The information provided in this episode of Unplucked is for informational and educational purposes only and should not be considered professional advice.
