US poultry producers have a new, FDA-approved weapon in the fight against Northern fowl mite (NFM) with Exzolt™ (fluralaner oral solution), a pioneering treatment from Merck Animal Health.
Merck Animal Health announced the US Food and Drug Administration (FDA) approval of EXZOLT™ (fluralaner oral solution), a parasiticide for chickens that treats and controls northern fowl mites (Ornithinyssus sylviarum) in production houses.
Data is playing a growing role in helping producers manage risk, optimize health and justify production decisions. From digitizing information to store it securely to using it to guide real-time decision-making, for Dan Wilson, DVM, founder of Wilson Veterinary Co., it has become integral to the way he works with producers to improve flock performance.
Faced with the emerging disease threat posed by avian metapneumovirus (aMPV), the USDA is allowing the importation of three vaccines from Boehringer Ingelheim: the live virus products NEMOVAC™ for use in chickens and AVIFFA RTI for use in turkeys and chickens, as well as the TUR-3 inactivated vaccine for primary vaccination of both turkey and chicken flocks against aMPV subtype B.
Low crude-protein diets are a well-proven practice to reduce diet cost and minimize excess nitrogen and excreta, thereby benefiting profitability, health and welfare in broilers and swine. However, the laying-hen industry is far behind in understanding the interaction and requirement of lower amino acids.
Regular monitoring of broiler drinking-water consumption helps track flock health and performance. A sudden dip or downward trend can alert the producer to potentially serious health or production problems.
As animal welfare science has evolved, the importance of using animal-based measures to study welfare has become apparent. Birds may have needs and feelings that aren’t immediately obvious to humans, and their priorities are influenced by an evolutionary history that is vastly different than our own.
The poultry gut is more than just a digestive organ — it’s a dynamic ecosystem that plays a critical role in bird health, disease resistance and overall performance. As the industry continues moving beyond blanket antibiotic use, producers and researchers alike are zooming in on the gut microbiome and how to manage it more effectively.
For every laying hen that is hatched, approximately one male counterpart also hatches. However, as roosters do not produce eggs, they are typically culled, or euthanized, at hatch. However, the culling of these day-old male chicks raises ethical concerns.
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.
The emergence of aMPV subtypes A and B has left US poultry producers seeking new tools to reduce the economic impact of this disease. In an interview, Silke Rautenschlein, PhD, professor at the University of Veterinary Medicine in Hannover, Germany, covers the past, present and future of the virus and its control.
