Consumer interest in poultry welfare has led to the expansion of unconventional poultry-rearing systems, such as silvopasture. Justin Lowery, MS, and a team of researchers from North Carolina State University conducted a broiler research trial comparing the impact of conventional and silvopasture production systems on the cecal microbiota of slow- and fast-growing broilers.

The Turkey Industry Annual Report, which gathers perspectives from producers and veterinarians working in the US industry, ranked aMPV, lack of efficacious drugs and HPAI as the top three management concerns among 39 reported issues. Report author Steven Clark, DVM, said he was not surprised by the trends.

When it comes to resisting bird flu, chickens on poultry farms are like sitting ducks. Last year, a highly pathogenic avian influenza virus, H5N1, ripped through poultry farms across the US, prompting farmers to cull tens of millions of chickens to contain the outbreaks. But far-UVC light may offer a safe and practical way to inactivate any type of virus in the air, reducing the chance of transmission.
Poultry researchers use ‘affective valence’ — a positive or negative emotional response — as a measure of animal welfare. Tom Smulders, PhD, an evolutionary neurobiology researcher from Newcastle University, has studied whether hippocampal neurogenesis can be a marker of affective valence in poultry.

Raised to maximize meat production, commercial turkey toms are bred to grow quickly and gain weight in a short time. This begs the question whether the bird’s skeletal system meets that developmental challenge.
By researching the impact of ectoparasite infestations in laying hens through a behavioral lens, Purdue University doctoral student Haley Sutherland aims to identify characteristics or heritable traits that help hens resist mite infestations.

New research suggests that probiotics can help protect broilers against gut diseases, such as necrotic enteritis. Increasingly, probiotics serve as a substitute for antibiotic growth promotants, which are no longer used.
In a Poultry Science Association webinar, Todd Applegate, PhD, assistant dean for international programs and department head of poultry science at the University of Georgia, shared his findings of a literature review on mycotoxins and discussed future research needs.
