A new vaccine-application approach shows advantages to help make on-farm, day-of-age vaccination easier to perform while increasing effectiveness.
Gangrenous dermatitis is a major commercial turkey-production disease, causing significant economic losses annually from increased bird deaths and condemnations at the processing plant. Can a litter amendment impact the spread of this bacteria?
The pathogen that caused spotty liver disease (SLD) in chickens from the 1950s to 1980s is re-emerging as a threat to poultry. Since 2018, Campylobacter hepaticus has been identified in laying birds in Iowa, Florida, Georgia and worldwide.
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.
In cage-free systems, it’s not only the birds that are moving around more freely. Bacterial transmission is also quicker and more efficient when birds roam uninhibited in large groups, underlining the importance of effective disease management.
Controlling foodborne pathogens in poultry requires nearly identical approaches whether production is conventional or antibiotic-free, according to Chuck Hofacre, DVM, PhD, president of the Southern Poultry Research Group, Inc.
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?
Novel disinfection strategies — electrostatic disinfection (ED) and cold fog (CF) disinfection — could help improve hatchability, reduce chronic respiratory disease (CRD) incidence and improve overall health outcomes for poultry, according to a recent Poultry Science report.
Ceva Animal Health has started antigen production for an experimental autogenous vaccine to fight the emerging avian metapneumovirus (aMPV) disease.
The global poultry industry spends billions of dollars annually to help ensure flock health, welfare, efficiency and performance. Faced with rising costs, a major US poultry company recently partnered with Ancera to monitor the effectiveness of its program for controlling coccidiosis.
Merck Animal Health reports that the USDA has approved the manufacturing and sale of Cambridge Technologies’ experimental autogenous vaccine in the US for the emerging and deadly avian metapneumovirus type B, impacting broilers, broiler breeders, layers and turkey breeders.
When weekly mortality rates in layer flocks older than 50 weeks start creeping up over 0.3%, producers and veterinarians should be suspicious. According to Eric Gingerich, DVM, Cargill’s Diamond V, these numbers could indicate the presence of Escherichia coli.
