Flocks vaccinated in ovo with HVT and CVI-LTR Marek’s vaccine show more immunity at hatch

Faced with the emerging disease threat posed by avian metapneumovirus (aMPV), the USDA is allowing the importation of three vaccines from Boehringer Ingelheim: the live virus products NEMOVAC™ for use in chickens and AVIFFA RTI for use in turkeys and chickens, as well as the TUR-3 inactivated vaccine for primary vaccination of both turkey and chicken flocks against aMPV subtype B.
The emergence of aMPV subtypes A and B has left US poultry producers seeking new tools to reduce the economic impact of this disease. In an interview, Silke Rautenschlein, PhD, professor at the University of Veterinary Medicine in Hannover, Germany, covers the past, present and future of the virus and its control.
An innovative vaccine designed to protect broilers against increasingly virulent forms of Marek’s Disease is helping producers rethink how they approach immune health, and how they use data to diagnose problems before they’re visible in the flock.
Coccidiosis doesn’t just lurk in poultry houses — it thrives there. For decades, producers have relied on synthetic anticoccidials and ionophores to keep it in check. But with growing resistance and increasing pressure to reduce antibiotic use, more operations are turning to vaccination as a sustainable, effective alternative.
What is the best way to safeguard poultry health across a wide range of production systems and management teams? That’s a question Rick Phillips, DVM, MAM, director of poultry professional services veterinarians at Boehringer Ingelheim, has explored for more than 25 years while working with live-production teams across the US.
USDA has authorized Boehringer Ingelheim to import two of the company’s live-virus vaccines for emergency use to help protect US poultry against avian metapneumovirus (aMPV) — a highly contagious respiratory viral infection that can result in severe respiratory symptoms and increased mortality in poultry.
Vaccines are essential tools for managing diseases in poultry and ensuring flock welfare. Taking shortcuts with them is never a good idea, however, and there’s plenty of research to prove it. In the second of a two-part series, Bill Stanley, DVM, and Isabel Gimeno, DVM, PhD, talked about their experiences managing vaccines and ensuring optimum performance.
Immunosuppression is a costly yet often misunderstood problem in the poultry industry. But what exactly is immunosuppression, and how can it be detected, diagnosed and measured? In the first of a two-part series, Isabel Gimeno, DVM, PhD, and Bill Stanley, DVM, share their expertise on this topic.
USDA has given Boehringer Ingelheim the green light to import TUR-3, a killed vaccine currently licensed for use throughout Europe for Newcastle disease, avian paramyxovirosis type 3 and turkey rhinotracheitis.
Is diet the rising X factor for optimizing immunity in poultry? Researchers at the Southern Poultry Research Group (SPRG) in Athens, Georgia, are building a strong case, via a growing body of research shedding new light on how diet influences the traditional pathogen-host-environment triangle for assessing disease risk.
Post-mortem examinations are essential for maintaining a comprehensive, targeted flock-health program. But when it comes to managing viral diseases, is it enough to look at the bursa?
