Biosecurity & One Health

In this episode of Unplucked, host Andy Vance talks with Dr. Rocio Crespo of North Carolina State University about what it really means to manage poultry health through a One Health lens. Dr. Crespo explains why many flock problems that appear to be infectious diseases often begin with nutrition and metabolism, and how delayed diagnosis keeps veterinarians chasing symptoms rather than causes. The conversation reframes production data as only part of the picture and makes a case for measuring what is happening inside the bird, from ionized calcium and mineral balance to early markers that flag risk before performance drops.   They explore the promise of precision livestock management and noninvasive monitoring that meets barns where they are. Dr. Crespo shares practical research on tools that can work at flock scale, including environmental gas sensing, sound analysis to detect changes in vocal behavior, and overhead camera systems that quantify eating, drinking, and movement without handling birds. She also walks through a realistic path to adoption, starting with randomized sampling and pilot measurements, then building toward smarter routines that fit labor, budgets, and equipment already on the farm.   If you want a grounded roadmap for moving from flock health to true animal health, this episode connects early diagnostics, precision monitoring, and economic biosecurity into a single, workable approach for modern poultry systems.   CREDITS Host - Andy Vance Producer - Lyndsey Johnson Audio Editor & Engineer - Michael Lunt   LEGAL The information provided in this episode of Unplucked is for informational and educational purposes only and should not be considered professional advice.
