Minimizing the concentration of mycotoxins in feed is key to preventing necrosis of the oral mucosa and esophagus, which decreases the ability of the digestive tract to digest and absorb nutrients.

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?
Sustainability issues demand significant attention today. And while it can be challenging to identify and implement strategies, sustainability will continue to drive decisions within the food-animal sector.
Egg-drop syndrome 1976 (EDS 76) was diagnosed in US broiler breeders — possibly the first incidence of its kind in the country.
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?
US consumers have misconceptions about how poultry is raised, including a widely held but erroneous belief that there are added hormones or steroids in chicken meat, a national survey suggests.
After a decade studying how to reduce losses from necrotic enteritis and gangrenous dermatitis on broiler farms, Don Ritter, DVM, an independent consultant who heads Poultry Business Solutions, Norfolk, Virginia, believes the industry is finally making progress against these two clostridial diseases.
A University of Minnesota research team is exploring options for moving uninfected eggs from farms where highly pathogenic avian influenza (HPAI) has been diagnosed and making them available to consumers.
Reality is sinking in. HPAI in the US is likely here to stay, and vaccination may be an option for long-term control, reported David Suarez, DVM, PhD, US National Poultry Research Center.
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.
