A joint research study conducted by the USDA and North Carolina State University researchers demonstrated that the type of housing system used for laying hens can influence levels of human pathogenic Salmonella in their organs.

Mobility and leg problems are common in modern-day broilers, which are bred for high breast-muscle yield. Extra activity can help the birds support the extra bodyweight and prevent skeletal disorders. Could colored lighting encourage broilers to be more active and less prone to leg problems?
Coccidiosis doesn’t just lurk in poultry houses — it thrives there. For decades, producers have relied on synthetic anticoccidials and ionophores to keep it in check. But with growing resistance and increasing pressure to reduce antibiotic use, more operations are turning to vaccination as a sustainable, effective alternative.
In a recent Poultry Science publication, researchers in Egypt and Saudi Arabia reported that prebiotic and probiotic supplementation in flocks vaccinated for coccidiosis did not alter vaccine effectiveness or improve short-term, vaccine-induced declines in growth performance.
As poultry companies weigh cost and efficiency with higher animal welfare standards, research comparing conventional and slow-growing broiler breeds showed that the slow-growing chickens displayed behaviors more closely associated with positive welfare.
Adding fishmeal into the diets of broiler breeder roosters could improve egg hatchability, North Carolina State University research suggests.

Avian metapneumovirus (aMPV) is now the leading health issue facing the US turkey industry, according to a recent survey of turkey industry professionals and veterinarians representing 73% of the 218 million birds raised in the US over 12 months ending August 2024.
