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.

UGA case study: Chlorine demonstrates mixed results in spotty liver disease outbreak

Campylobacter hepaticus has been identified as the causative agent in spotty liver disease, so when Roel Becerra, DVM, received a phone call from a producer that had free-range, antibiotic-free, brown layer hens with SLD, he and fellow investigators decided to study chlorine as a possible treatment.

Stocking density variably affects broiler activity, welfare

Providing the proper stocking density to maximize broiler productivity, welfare and profitability is a balancing act. Because the birds grow dramatically in just a few weeks, space and environmental demands continuously evolve.

Caution needed when adjusting broiler calcium concentration, limestone particle size

Reducing dietary calcium concentrations in broiler diets can increase calcium and phosphorus digestibility, but deviating from recommended levels can come with costs, according to the results of an Auburn University study.
