Drawing on more than 70,000 hatchery vaccination audits conducted through Ceva Animal Health’s C.H.I.C.K Program, Alba Pfaff, MS, the company’s senior technical marketing manager, discusses what helps hatcheries maintain high vaccination standards, the details that matter most and how better use of data could support even greater consistency.
Modern commercial chicks hatch into a very different world than they would under natural conditions. According to Ivan Rychlik, DVM, researcher at the Czech Republic’s Veterinary Research Institute, that difference has major consequences for gut health, disease resistance and antibiotic use.
Ivan Alvarado, DVM, PhD, Merck Animal Health, discusses the research which has highlighted the health and production benefits of using recombinant HVT vaccines at the hatchery alongside live vaccines against infectious laryngotracheitis and Newcastle disease.

When vaccine decisions are grounded in sound diagnostics and veterinary guidance, but flock performance does not improve as expected, the vaccine itself may not be the problem. It may be time to review how the product was stored, prepared and applied. Abigail Graham, DVM, MAM, DACPV, Zoetis, explains how.
For poultry companies, a successful infectious bronchitis vaccination program depends on more than choosing the right vaccine for the challenge at hand. According to Jose Linares, DVM, Ceva Animal Health, consistently high vaccine takes depend just as much on the quality of vaccine application.
In the third installment of Phibro Academy’s three-part webinar series, “Coccidiosis Tools and Strategies,” Greg Mathis, PhD, president of Southern Poultry Research, Inc., discusses anticoccidial sensitivity testing and how best to interpret results and apply them in the field.

Hatchery day-of-age vaccination has been a cornerstone of broiler health for decades, but new research led by Rodrigo Gallardo, DVM, PhD, UC Davis School of Veterinary Medicine, is shedding light on the mechanisms that help it protect chicks despite the immaturity of their immune systems.
When faced with these emerging IBDV variant strains, it’s important to provide every chick the strongest possible immune start while keeping pace with a changing virus. Kalen Cookson, DVM, MAM, DAPVC, director of clinical research, Zoetis, provides vaccination strategies for poultry vets to consider.
A university challenge study has examined how recombinant HVT-ILT vaccines used at the hatchery affect the response to live, chicken-embryo-origin ILT vaccines applied later as part of a dual infectious laryngotracheitis vaccination program.
Researchers at North Carolina State University evaluated the effects of housing systems and genetic strains on broiler mobility in slow-growing strains vs fast-growing strains in both indoor and outdoor environments.
