In some regions, the threat of infectious bronchitis virus flare-ups has shaped a long-held industry mindset: when bronchitis pressure rises, it may be safer to pull back on live Newcastle disease vaccination to avoid “stacking” respiratory vaccines. However, Roy Jacob, DVM, PhD, senior key account veterinarian at Boehringer Ingelheim, says this need not be the case.
By researching the impact of ectoparasite infestations in laying hens through a behavioral lens, Purdue University doctoral student Haley Sutherland aims to identify characteristics or heritable traits that help hens resist mite infestations.
Manuel Da Costa, DVM, PhD, Director of strategy and innovation, Cargill, takes an interesting look at coccidiosis programs and how the company’s feed additive, Biostrong™ Dual, can impact broilers’ gut health to defend against this disease.
Research from Ceva Animal Health suggests that eggshell rinses may be a viable, accessible way to detect infectious bronchitis virus infection in layer flocks experiencing egg quality abnormalities.
One Newcastle vaccine strain drawing renewed attention is VG/GA. Long valued for being gentle on young chicks, VG/GA works differently from traditional respiratory Newcastle vaccines. And according to Chuck Hofacre, DVM, PhD president of the Southern Poultry Research Group and a longtime consultant to the broiler industry, that difference is worth a closer look.

The composition and functionality of the gut microbiota are increasingly recognized as critical determinants of poultry performance. The Galleon™ microbiome intelligence platform was developed to help identify the most important gut biomarkers linked to performance and health.
New research suggests that probiotics can help protect broilers against gut diseases, such as necrotic enteritis. Increasingly, probiotics serve as a substitute for antibiotic growth promotants, which are no longer used.
The latest technology providing access to feed and water in hatcheries could change how vaccinations and other general practices are conducted. Katherine Schaefbauer, Jennie-O Turkey Store, led a research trial with a coccidiosis vaccine administered to fed and non-fed turkey poults in the hatchery, and presented the results at the 2025 AAAP Meeting.
A new rapid testing method is helping poultry producers detect Salmonella faster and more efficiently than ever before. The method, developed by Ceva Animal Health, dramatically shortens turnaround time while reducing testing costs by nearly two-thirds, according to James Mills, scientist at Ceva Animal Health.
Commercial trials have demonstrated the efficacy of Avert® NE from Huvepharma against necrotic enteritis in commercial broiler facilities. David Smith, DVM, MS, director of poultry technical services at Huvepharma discussed these trials, which evaluated livability and zootechnical performance of birds given the vaccine, pointing to improvements in vaccinated flocks compared to unvaccinated birds.
