In the last 2 decades, strides in poultry nutrition helped build profitability for poultry producers in the US and around the world. Average US feed-conversion rates (FCR) have improved by 23 points (0.23) since 2000, according to Michael Kidd, PhD, professor in the Department of Poultry Science at the University of Arkansas.
Poultry genetics has evolved rapidly in the last 2 decades and continues to advance steadily, but research from Cargill Animal Nutrition suggests that birds’ diets need to be updated alongside genetic progress to maximize performance.

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.
Ceva Animal Health has started antigen production for an experimental autogenous vaccine to fight the emerging avian metapneumovirus (aMPV) disease.
The message is clear and one that Daral Jackwood, PhD, The Ohio State University, has delivered for years: Young chickens need maternal immunity to protect them from immunosuppression and secondary diseases caused by infectious bursal disease.
With a price tag of over $1 billion for indemnity payments, the current outbreak of highly pathogenic avian influenza (HPAI) is expensive. Is premise depopulation still the way to manage HPAI?
A dual case of Mycoplasma gallisepticum and Mycoplasma synoviae in a broiler breeder flock in northeast Georgia exposed expensive biosecurity shortfalls of which producers should take heed.
It’s no secret that the fertility and egg hatchability of a broiler breeder flock decrease as birds age. But in recent years, there has been a broader, overall decline.
Hens can positively influence the skin and respiratory tract microbiota of newly hatched chicks, according to a study published in Poultry Science.
Despite the industry’s best efforts to control colibacillosis in layers, broilers and breeders, the bacterial disease caused by avian pathogenic Escherichia coli (APEC) continues to challenge producers and researchers.
Most poultry producers today use vaccines to help manage coccidiosis. Live coccidial vaccines are designed to uniformly infect birds with a controlled number of Eimeria oocysts to stimulate a protective immune response, but not all vaccines are the same.
