High-quality vaccine application is essential for infectious bronchitis (IB) control, but it's only one part of the picture. Jose Linares, DVM, diagnostician and technical services veterinarian with Ceva Animal Health, discusses why successful IB control requires more than simply administering vaccine.
Most poultry companies invest significant resources in infectious bronchitis vaccination programs. But according to one of the poultry industry's leading infectious bronchitis virus researchers, Mark Jackwood, PhD, Ceva Animal Health, one critical question often receives less attention than it should: How do you know the program worked?
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.
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.
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.
What does it mean when Newcastle disease virus appears in diagnostic testing during respiratory disease investigations? According to Mark Jackwood, PhD, and Jose Linares, DVM, of Ceva Animal Health, the answer often has less to do with Newcastle itself and more to do with the complex mix of pathogens affecting commercial flocks.
As resistance continues to erode the effectiveness of traditional anticoccidial programs in turkeys, veterinarians are increasingly focused on strategies that protect birds while preserving available tools. A multi-year field experience with a US heavy tom producer suggests that coccidiosis vaccines can play a practical role in conventional rotation programs.
Abstract: Sample to vaccine via an integrated cross-functional NGS network
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.
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.
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.
Controlling IBV through vaccination requires knowledge of the circulating field strains. For this reason, surveillance is critical. Mark W. Jackwood, PhD, and Jose Linares, DVM, describe Ceva’s Scientific Support and Investigation Unit that uses real-time quantitative RT-PCR panels to rapidly detect multiple IBV types.
A broiler-immunization program centered on a live monovalent vaccine containing the Georgia 08 (GA08) serotype of infectious bronchitis virus (IBV) is showing benefits to protect broilers against the Delmarva/1639 (DMV/1639) serotype of IBV.
Turkey veterinarians and producers are increasingly turning to coccidiosis vaccines and using them in a rotation with anticoccidials in the feed as a standard component in their prevention programs. Kelli Jones, DVM, MAM, Ceva Animal Health, shares tips for successfully using coccidiosis vaccination.
Day-old birds immunized with vaccines for Georgia (GA) and Massachusetts (Mass) serotypes of infectious bronchitis virus (IBV) were shown to be protected against four other circulating IBV variants in a recent study.
A new vaccine-application approach shows advantages to help make on-farm, day-of-age vaccination easier to perform while increasing effectiveness.
Ceva Animal Health has started antigen production for an experimental autogenous vaccine to fight the emerging avian metapneumovirus (aMPV) disease.
