Questions remain as search continues for solutions to emerging bacterial threat

Enterococcus cecorum was first reported in the US in 2009. Disease caused by this pathogen poses considerable welfare and economic challenges for broiler producers and currently has no effective antibiotic-free treatment. For the past 15 years, Mitsu Suyemoto, research specialist at North Carolina State University, has conducting pioneering research on this emerging pathogen with Luke Borst, DVM, PhD. Of note, their team developed many of the key assays used to study E. cecorum today.

NC State researcher: Autofluorescence accurately evaluates Eimeria oocyst viability

Research led by Phillip Yeboah, PhD candidate at North Carolina State University examined autofluorescence as a method for determining whether Eimeria oocysts are viable and capable of causing infection.

Organic acids have little effect as a Salmonella intervention in broiler study

Adding organic acids to poultry drinking water has been suggested as a potential intervention in managing Salmonella, but research by Auburn University scientists showed otherwise.

AAAP panelists discuss challenges, promises of serotyping techniques for IBV

Brian Jordan, PhD, associate professor at the University of Georgia joined T.J. Gaydos, DVM, and Rodrigo Gallardo, DVM, PhD, as panelists in a webinar from the AAAP. They discussed the challenges and promises of IBV serotyping with qPCR and sequencing.

Infectious coryza expands its geography, complicates diagnosis

Infectious coryza, a bacterial upper respiratory disease, is on the rise in the US. Avibacterium paragallinarum, which is a primary pathogen of chickens causing coryza, spread from southern states to Pennsylvania in 2018, followed by Ohio, Iowa and other northern states.

Fast-growing broilers perform well in silvopasture and indoor production facilities

A North Carolina State University study, led by graduate student Athena He-DeMontaron, compared the growth performance and mortalities of fast- and slow-growing strains of broilers reared in silvopastures, which provide a natural habitat with trees, shrubbery and vegetation and indoor facilities. How did these systems impact the different bird strains?

Virginia Tech researchers report varying benefits of emulsifiers in layer hens

Feed additives, which facilitate nutrient transport in birds, can help producers counter the rising costs of energy sources in poultry diets and loss of resources resulting from the competition for these ingredients. Emulsifiers could be a promising option here.

Potential in ovo sexing options could end male-chick culling

A new in ovo sexing technique with a modified genetic trait to hatch only female chicks may someday help eliminate the culling of day-old male chicks. According to developer and embryologist Yuval Cinnamon, PhD, the genetically based solution offers many benefits over the other technologies currently on the market.
