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.

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.
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.
Eric Shepherd, DVM, Zoetis, takes a look at potential IBD vaccination programs that may disrupt field virus pressure, restore disease control and support overall flock health.
In the United States, the majority of laying hens are housed in conventional cages. However, there has been a shift towards cage-free systems. Cage-free systems can benefit laying hen welfare. Birds have opportunities to perform a full range of species-specific behaviors, including foraging, dustbathing, perching, and walking, which are restricted in conventional cages.
Gut inflammation is common throughout poultry production, but its effects are not always visible. Birds deal with stress every day through changes in environment, feed adjustments, handling and exposure to coccidiosis and other intestinal diseases. All of these changes trigger the immune system to send a response to manage the inflammation.
Industry experts, Steven Clark, DVM, Huvepharma’s veterinary technical services manager and Elizabeth Beilke, DVM, West Liberty Foods’ corporate veterinarian, were featured on the Iowa Turkey Federation’s Turkey Talkshow podcast to discuss the role of vaccines in coccidiosis management.
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.
