HPAI is a significant threat to the poultry industry, and vaccination alone is not enough to combat this virus, said David Swayne, DVM, PhD, DACVP, a former USDA scientist who has spent more than 30 years studying this disease. Swayne discussed HPAI vaccination programs, addressing four misconceptions about the vaccines.

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.
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.
In nature, fear protects animals from danger. In commercial settings, domestic laying hens are shielded from most fear-inducing stimuli, such as predators and unfamiliar situations. Therefore, fear serves as an aversive experience for the hens themselves and leads to undesired behaviors for producers.
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.
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.
