Since it was first isolated in broiler flocks on the Delmarva Peninsula, the latest mutation of infectious bronchitis virus (IBV), DMV/1639, has spread through the eastern seaboard of the US and west toward Mississippi and Texas.
Commercial egg-laying operations can benefit from more effective and economical ways to depopulate flocks at the end-of-lay while improving worker performance and maintaining or improving animal welfare.
Researchers from Egypt and Saudi Arabia conducted a study to determine if adding eucalyptus (EL) powder as a dietary supplementation would have an effect on productive performance and immune response in two varieties of Japanese quail.
The US Environmental Protection Agency (EPA) wants to use updated computerized models to guide regulation of air pollution by animal feeding operations, including broiler chicken farms.
Preventing disease transmission between flocks is a major goal of the poultry industry. One threat to bird health is the protozoan Histomonas meleagridis, which causes a disease called histomoniasis.
When humans domesticate and breed an animal, they tend to select for a very specific trait. In laying hens, artificial selection for high egg production has led to hens that can produce 320 eggs a year. But could artificial selection have unintentionally altered hen brain morphology?
There are many pests and pathogens to monitor on poultry farms, but bed bugs typically aren’t top of mind. Nevertheless, bed bug infestations have been resurfacing in US poultry farms. Does that present a health, performance or welfare problem for flocks?
Light intensity has been shown to affect the activity of birds, but most studies have focused on constant light intensities to determine their effect on welfare.
Colibacillosis resulting from E. coli is arguably one of the major causes of morbidity, mortality and carcass loss to the poultry production industry worldwide, putting at risk one of the cheapest and most valuable sources of protein.
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.
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.
Broiler chicks can be provided between 1 to 4 hours of darkness a day without negative consequences, according to a recent study.
