The One Health approach, which encompasses human, animal and environmental health, is well-suited to address a disease issue such as HPAI, according to Meghan Davis, DVM, PhD, associate professor at John Hopkins Bloomberg School of Public Health and Engineering.

Gut health is often discussed in poultry production. But according to immunologist Michael Kogut, PhD, lead research microbiologist at the USDA-ARS, College Station, Texas, the term is really about gut homeostasis, which enables birds to maximize performance and reach their full potential.

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.
Amino acid requirements for laying hens are not well understood, primarily because data are lacking for the pullet stage. This gap is increasingly important as the table-egg industry wants to extend the hen’s life cycle to 100 weeks or more. Jo Ann Chew, graduate research assistant, University of Alberta, investigated how amino acid levels during rearing might impact body fat and the onset of lay.
At the 2025 Poultry Science Association annual meeting, Michael Carroll, graduate assistant at Iowa State University, presented his research investigating whether dietary changes can produce a useful immune response to combat necrotic enteritis.
Woody breast, sometimes called wooden breast, has become a familiar and costly problem for today’s broiler industry, according to Cirenio Hisasaga, doctoral student at the University of California– Davis.
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.
Nearly 800 poultry health professionals from more than 25 countries will gather in Orlando, Florida, from July 28 to 30 for the 2026 conference of the American Association of Avian Pathologists (AAAP).

Research on broilers is often applied to commercial turkeys, as is the case with many studies on photoperiod lengths. At the 2025 Poultry Science Association annual meeting, Karen Schwean-Lardner, PhD, University of Saskatchewan, presented results of her study that were specific to turkeys.
