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.
