An innovation taking the broiler/breeder industry by storm is Comfort Nest™, a mechanical egg-laying system from VAL-CO that more than doubles the nest size to accommodate high-yield broiler-strain hens.
Hatchery day-of-age vaccination has been a cornerstone of broiler health for decades, but new research is shedding light on the mechanisms that help it protect chicks despite the immaturity of their immune systems. The findings are significant because it is widely used throughout the poultry industry, yet relatively little is known about how newly hatched chicks develop protection following vaccination.
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.
The poultry industry has spent decades chasing infectious bronchitis virus, adjusting vaccination programs and developing new vaccines as new variants emerge. Yet despite those efforts, the cycle continues. However, Mark Jackwood, PhD, one of the world’s leading IBV researchers, says that’s not a sign that vaccination has failed. It’s simply the nature of the virus.
In the second installment of Phibro Academy’s three-part webinar series, “Coccidiosis Tools and Strategies,” Greg Mathis, PhD, president of Southern Poultry Research, Inc., made it clear that effective coccidiosis control today depends less on new product development and more on how well existing strategies are combined.
The Turkey Industry Annual Report, which gathers perspectives from producers and veterinarians working in the US industry, ranked aMPV, lack of efficacious drugs and HPAI as the top three management concerns among 39 reported issues. Report author Steven Clark, DVM, said he was not surprised by the trends.
Eric Shepherd, DVM, Zoetis, takes a look at potential IBD vaccination programs that may disrupt field virus pressure, restore disease control and support overall flock health.
In the opening session of Phibro Academy’s three-part webinar series, “Coccidiosis Tools and Strategies,” Greg Mathis, PhD, president of Southern Poultry Research, Inc., focused squarely on anticoccidials and the importance of long-term planning with rotation and shuttle programs.

Industry experts, Steven Clark, DVM, Huvepharma’s veterinary technical services manager and Elizabeth Beilke, DVM, West Liberty Foods’ corporate veterinarian, were featured on the Iowa Turkey Federation’s Turkey Talkshow podcast to discuss the role of vaccines in coccidiosis management.
According to Steven Clark, DVM, Huvepharma’s veterinary technical services manager, paying attention to changes in turkey barns is key to successfully using ionophores, which remain the industry’s most common option for controlling coccidiosis.
