Vaccine Roulette: Why NDV Strain Selection Could Be Costing You

Newcastle disease is largely under control in the United States, yet vaccination choices still shape flock health and performance. In this episode, host Andy Vance talks with Dr. Brian Jordan of Zoetis about why not all Newcastle vaccines behave the same inside the bird and how a data-first approach can reveal hidden gaps in protection.
 
Dr. Jordan explains the concept of vaccine take, how routine PCR monitoring shows whether birds actually received and replicated a live vaccine, and why low take rates can set up a rolling reaction that chips away at growth, feed conversion, and overall flock immunity. He compares popular live strains and clarifies where recombinant options fit, then walks through a simple plan for spot-checking hatchery applications, reading CT distributions, and deciding whether the problem is process or product. The conversation closes with questions veterinarians should ask suppliers, how to layer Newcastle programs with other respiratory vaccines, and why quarterly monitoring can keep protocols honest without adding constant lab costs.

Pathogen Pursuit: Campylobacter

Campylobacter is not your typical poultry pathogen. In this episode of Unplucked, host Andy Vance talks with Dr. Issmat Kassem of the University of Georgia Center for Food Safety about why this bug survives where others do not, and what that means for food safety from farm to processing plant. Dr. Kassem explains how Campylobacter thrives in the chicken gut, why its biology and genetics break some of the rules we apply to Salmonella and E. coli, and how the diversity of strains on farm narrows to a persistent few that make it through processing. The conversation traces how those processing tolerant strains complicate detection and control, and why a single intervention is rarely enough.
Listeners get a clear view of where the science is headed. Dr. Kassem outlines work to speed up detection and quantification, including modified media and approaches that target the microbe’s unique metabolism. He shares experimental results on antimicrobial light and new phytochemicals that can be layered with established interventions to improve reductions without sacrificing product quality. The discussion also zooms out to a practical message for the entire chain. Keep improving the system that already works, add smart hurdles where they fit, and invest in consumer education so safe handling keeps pace with scientific progress. Above all, remember that pathogens evolve, so our playbook must evolve too.

Inside Perdue Farms: Reinventing Poultry Feed

In this episode of Unplucked, host Andy Vance sits down with Dr. Randy Mitchell, VP of Nutrition at Perdue Farms and a newly named Fellow of the Poultry Science Association, to examine how one of America’s most recognized poultry brands turns values into daily practice. Dr. Mitchell traces his path from a North Georgia farm to corporate leadership and explains how Perdue’s family-owned culture shapes decisions that reach from feed mills to grower barns. The conversation looks closely at two defining shifts for the company, the move to all-vegetarian feed and the transition to no antibiotics ever, and unpacks the research, cross-functional coordination, and grower engagement needed to make those commitments work at scale.
Listeners get a practical view of formulation under new constraints, including how broader access to plant proteins, synthetic amino acids, and feed-grade vegetable oils helped close performance and cost gaps. Dr. Mitchell discusses why the hardest work was not removing in-feed antibiotics but redesigning hatchery and farm programs to protect chick quality, litter condition, and overall flock health. He shares how Perdue evaluates tradeoffs, from bird welfare to customer expectations, and how the company weighs the real "cost of being Perdue" while staying competitive on throughput and efficiency.

How are AI & Robotics different?

Artificial intelligence and robotics are not the same tool, and understanding the difference changes how you plan, budget, and deploy technology in poultry science. In this episode, host Andy Vance talks with Georgia Tech’s Walker Bynes about where fixed automation ends and flexible robotics begins, and how AI fits in as the decision layer rather than the machine itself. Walker explains why most plants still rely on purpose-built machines for single tasks, and how the next wave aims for adaptable systems that can be reprogrammed to handle new jobs as conditions change in the house, the lab, or the plant.
 
The conversation breaks down embodied AI in plain language. Listeners hear how vision and language models help robots perceive space, generate action plans, and learn from complex sensor data, and why the quality of inputs, clear guardrails, and human oversight are essential for safety and reliability. In the lab, AI and automation act as a force multiplier by removing repetitive work and surfacing better experiment plans, while researchers stay in control of the science. Looking ahead, Walker sketches a practical roadmap that includes domain-specific models trained on poultry data, flexible robots that can be upskilled with software, and interdisciplinary teams that pair engineers with poultry experts to turn promising ideas into daily routines that save time and improve outcomes.

Broiler House Management

Moisture control sits at the center of good broiler management. In this episode of Unplucked, host Andy Vance talks with Dr. Brian Fairchild of the University of Georgia about the house as a living system and how small environmental choices cascade into flock health, welfare, and costs. Dr. Fairchild explains why design and day-to-day execution both matter, how ventilation strategies should change with the season, and why chasing ammonia with more fan time often backfires by driving energy use without fixing the root problem. He walks through practical ways to keep a steady moisture balance, from programming controllers against real outdoor and indoor conditions to avoiding early morning evaporative cooling that only saturates the air.
The conversation expands into the decisions producers face on lighting, energy, and water. Dr. Fairchild outlines how LED technology lowered power bills and why aging bulbs with uneven spectra can undermine dimming programs if replacements are not chosen carefully. He shares a simple framework for water management that starts with peak flow capacity, then looks at quality through the lens of equipment reliability, because leaky or worn drinkers can create wet floors long before bird performance suffers. Listeners also get an inside look at innovations with staying power, including variable-speed fans that move the right amount of air at lower cost and newer plastic evaporative pads that tolerate poor water quality and can be cleaned effectively. Throughout, Dr. Fairchild ties research to the barn, showing how field trials, extension newsletters, and producer feedback turn ideas into routines that protect margins and keep birds comfortable.

Hatchability

Hatchability has quietly slipped in the United States over the last decade, and the cost shows up everywhere from breeder houses to the balance sheet. In this episode of Unplucked, host Andy Vance talks with industry veteran Doug Ward about why there is no single fix and why the biggest wins often come from getting the basics right. The discussion explores how older hatchery infrastructure, changing genetics, and uneven incubation can cloud what looks like a fertility problem. It also explains why male management matters just as much as hen nutrition, how litter quality and ventilation drive foot health and mating behavior, and where shell quality and egg handling intersect with new, high-throughput collection systems to make or break a hatch.
Listeners will come away with a practical checklist for improving results. Focus on feed quality on breeders rather than shaving pennies, keep a rigorous biosecurity program, ventilate for dry litter, invest in hatchery QA and breakouts so teams can manage what they measure, and maintain equipment so it performs to design. The episode also looks ahead at tools that could shift the curve, from precision sorting and pullet uniformity to AI-assisted chick sexing and targeted microbial strategies that support both performance and food safety.

The Coccidiosis Conundrum: Progress or Plateau?

In this episode of Unplucked, host Andy Vance talks with Dr. Kayla Price of Alltech Canada about what it really takes to make progress against coccidiosis, one of poultry’s most persistent and costly challenges. The conversation cuts through the assumption that a tidy parasite life cycle leads to tidy control. In the barn, multiple pressures collide, from bird behavior to management realities, and the simple model gives way to a complex gut ecosystem that demands better prevention, smarter diagnostics, and tighter collaboration between researchers and producers.
Dr. Price explains how a deeper understanding of the microbiome can reshape control strategies, why host and species specificity matter when moving from lab results to farm decisions, and where genomics, metagenomics, and artificial intelligence can turn fecal samples into practical, point-of-care insights. She offers a clear case for rethinking diagnostics so that earlier detection does not always require opening birds, and for designing tools that fit the pace and constraints of commercial houses.
The episode also explores how to speed innovation without losing rigor. Dr. Price shares lessons on closing communication gaps between academia and industry, aligning projects with funder goals without compromising scientific questions, and writing for journals in ways that help readers understand the why and the how. Her advice is simple and powerful: Invite field perspectives earlier, value negative results as much as positive ones, and build a pipeline that carries ideas from bench to broiler house through honest feedback and continuous iteration.

The Science Behind Modern Broilers

In this episode of Unplucked, host Andy Vance sits down with Dr. Doug Korver to unpack what decades of genetics and nutrition have really done to modern broilers, and what it means for the next decade of poultry production. Dr. Korver explains why visual storytelling matters just as much as data, reflects on the iconic side-by-side comparisons of broilers across eras, and lays out the simple truth that biology has limits. The conversation explores the trade-offs behind faster growth and improved feed efficiency, the consequences for bone health and meat quality, and why issues like myopathy and breeder restrictions require fresh thinking about selection goals, management, and maternal nutrition.
They move from the bench to the barn, discussing why tightly controlled research does not always translate cleanly to 60,000-bird houses, and how to bridge that gap through practical trial design and collaboration. Dr. Korver shares insights from his work on the National Academies committee updating poultry nutrient requirements, including the push for models that keep pace with changing genetics and the reality that many vitamins and minerals are still fed with wide safety margins. This episode also looks at forces beyond the farm, from consumer perception to policy, and why true sustainability must include economics, welfare, environmental impact, and a product people still want to buy.

A Gut Feeling: Turning Gut Science into On Farm Results

In this episode of Unplucked, host Andy Vance talks with Dr. Lisa Bielke of NC State about what gut health really means in poultry and why bacteria in the gut are not just along for the ride. Dr. Bielke traces her path from early probiotic work to today’s omics era, explains how data is reshaping what we know about the microbiome, and shares why selecting probiotics for specific functions can deliver benefits that go well beyond food safety.
The conversation covers emerging challenges in turkeys, including Eimeria and Histomoniasis, and unpacks how behavior, production systems, and regional disease pressure make turkeys a distinct scientific and management puzzle compared to broilers.
Together, Andy and Lisa dig into vertical transmission from breeders to chicks, why this early microbial handoff may explain inconsistent probiotic results, and how Salmonella can quietly impair performance through inflammation even when birds look healthy.
Dr. Bielke discusses practical ways to measure inflammation, the push to translate lab insights to on-farm decisions, and why the future of microbiome work is not only about disease control but also about improving nutrition and longevity. This episode is packed with great insights and advice for current and future poultry scientists out there.

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.
