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.

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.
