Jose Linares, DVM, a diagnostician and technical services veterinarian at Ceva Animal Health, said pre-winter surveillance – including reverse transcription quantitative polymerase chain reaction (RT-qPCR) testing, sequencing and processing-age serology – can help veterinarians and producers validate current IBV immunization strategies and ensure they are relevant and effective.
Salmonella exposure to consumers from eggs has been a decades-long concern. Richard Gast, poultry research microbiologist at USDA’s US National Poultry Research Center in Athens, Georgia, has developed two research projects to gain more perspective on Salmonella Enteritidis in cage-free layer housing.
In the poultry sector, avian metapneumovirus (aMPV) infections can lead to severe economic repercussions, manifesting as drops in egg production and increased mortality, which lead to costly veterinary interventions and biosecurity measures. Researchers described the development of an assay, which was found to be capable of concurrently detecting and distinguishing among aMPV-A, aMPV-B and aMPV-C.
Bone and leg health issues are among the top five common concerns for broilers, noted Gigi Lin, DVM, DACPV, adding that “Lameness can indicate not only a potential disease issue but is a welfare and economic concern.” Lin, a veterinary consultant with Canadian Poultry Consultants, Ltd, was featured in the 2025 Canadian Poultry’s Broiler School Series webinar presentation, “Understanding and Managing Lameness in Broilers.”
Alternatives to antibiotic growth promoters can maintain broiler performance. But replacing antibiotics is not a simple matter of like-for-like replacements, according to Doug Korver, PhD, professor of poultry nutrition at the University of Alberta.

Post-mortem exams help determine mortality causes and which health challenges birds are encountering. But conducting necropsies on healthy birds can also provide the perspective needed to distinguish between what’s normal and abnormal for a particular flock.
Pathogenic Enterococcus cecorum is proving to be a growing problem on broiler farms, and infection extends beyond bird-to-bird contact to the farm environment, according to a study led by Martine Boulianne, DMV, PhD, DACPV, at the University of Montreal.
