Developing a thorough vaccination strategy for fowl cholera — one that includes selecting the right vaccine strain for the field challenge that the birds are facing and proper vaccine administration — is critical when managing this bacterial disease.
Levels of copper in broiler diets may be contributing to an increased incidence of gizzard lesions in the southeastern US.
Pathogenic Enterococcus cecorum continues to plague the broiler industry, causing mortality from pericarditis and sepsis early in the growing period and lameness and paralysis late in the growing period.
Selecting broilers for water-conversion ratio has no effect on other economically important traits, potentially paving the way for a route to greater sustainability in production.
Broiler chicks can be provided between 1 to 4 hours of darkness a day without negative consequences, according to a recent study.
Help may be on the way for broiler flocks suffering from lameness caused by bacterial disease, with a new vaccine being developed and tested at the University of Arkansas as part of a project led by Adnan Alrubaye, PhD.
Abrupt rises in mortality from highly pathogenic avian influenza (HPAI) can set off alarms at any poultry farm. Such was the case last year with an outbreak in a layer flock in Iowa.

Even with the best flock-management and vaccination protocols, fowl cholera can occasionally find a crack in the system. Chronic, low-grade cholera problems can materialize, or occasional breaks in breeder flocks can suddenly appear.
A drop in USDA’s broiler chicken hatchability rates from 85% to less than 80% in the past decade runs counter to the poultry industry’s improvements in production efficiency, but making just a small improvement in hatchability can create significant economic benefits.
Years of painstaking research to discover how Salmonella metabolically survive is yielding unusual insights into these resourceful bacteria.
Researchers from Spain and the Netherlands performed a study to determine if adding a mineral and vitamin mix (AHS and Vitamin C) would have an effect on broiler performance in heat-stressed conditions.
