Eric Shepherd, DVM, and Brian Fairchild, DVM, recently offered practical advice for reducing disease risk in poultry environments. They spoke in a webinar sponsored by the Poultry Science Association and American Association of Avian Pathologists and presented six tips they gathered while working with poultry farms.
When it comes to drinking water for poultry, Susan Watkins, PhD, has a lot to say. Most important: Don’t neglect it. At the Devenish Symposium held during the 2025 PEAK conference, Watkins, a consultant and distinguished professor emeritus at the University of Arkansas, offered practical advice for keeping poultry water clean.
The shift to cage-free layer housing opened the door to poultry diseases that disappeared during the years of cage housing. At the Devenish Symposium held during the 2025 PEAK conference, Dan Wilson, DVM, Wilson Vet Co., discussed the return of several diseases from the past that affect today’s egg layers.
Abstracts & Posters, a new editorial section on Modern Poultry featuring research presented by industry scientists at major poultry conferences, is now available to readers.
Layer hens in cage-free housing systems have freedom of movement, but they also encounter high levels of dust and airborne bacteria. Feed, litter, manure and bodily shedding all contribute to dust within the rooms, which challenges the hens’ health and well-being. Could spraying acidic electrolyte water on the litter floor be a solution?

Abstract: A field study of Clostridium perfringens enumeration methods in the broiler house environment
Abstract: Comparative effects of ionophore anticoccidials with or without the addition of a QY phytogenic on performance and coccidia lesion scores in broilers challenged with contemporary coccidia strains.
Faced with the emerging disease threat posed by avian metapneumovirus (aMPV), the USDA is allowing the importation of three vaccines from Boehringer Ingelheim: the live virus products NEMOVAC™ for use in chickens and AVIFFA RTI for use in turkeys and chickens, as well as the TUR-3 inactivated vaccine for primary vaccination of both turkey and chicken flocks against aMPV subtype B.
Bird health and production are significantly impacted by air quality, humidity and temperature. Mechanical ventilation systems play a crucial role in maintaining indoor air quality and disease control, but the current systems have limitations, particularly in caged-layer facilities. Researchers from The Ohio State University have designed an innovative ventilation system that addresses health and heat concerns.
