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.

Feeder management: A vital part of broiler welfare

Feed is a vital part of the poultry industry, representing around 60-70% of the total costs. However, even the best feed formulation cannot deliver results if the birds cannot access it readily. Anusha Gautam and Bethany Baker-Cook, PhD, Auburn University, discuss the right type of feeders to select for each of the production phases, appropriate feeder spacing, proper feeder height, and the overall feeder arrangement.

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?
