No easy answers for preventing gangrenous dermatitis outbreaks

Known for high mortality and low morbidity, gangrenous dermatitis (GD) continues to evade answers as researchers investigate potential stressors that trigger an outbreak. Matthew Jones, DVM, Southern Poultry Research Group led a panel of poultry professionals that included Don Ritter, DVM, Chuck Hofacre, DVM, Mark Burleson, DVM, and Carrie Cremers, DVM, to discuss field experiences that helped control GD.

Six practical ways to safeguard flock health

Eric Shepherd, DVM, MS, MAM, DACPV, poultry veterinarian, and Brian Fairchild, PhD, Extension Poultry Scientist and Professor, University of Georgia Department of Poultry Science, recently offered practical advice for reducing disease risk in poultry environments. Both spoke in a webinar sponsored by the Poultry Science Association and American Association of Avian Pathologists.

Watkins: Six tips to conduct water assessments for poultry

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.

Wilson: Old diseases are back with cage-free production

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.

New ventilation system design holds promise for heat and air quality concerns in manure-belt layer houses

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.

Zhao: Novel ammonia-capturing technology provides a win-win scenario

Maintaining indoor air quality is a constant concern for poultry producers. In particular, ammonia levels within houses are a health concern for poultry and workers. But what about the ammonia in exhausted air? Researchers from the University of Georgia are using a novel approach to remove and recover ammonia from large layer-poultry facilities.

Technologies can help producers reduce risks of dust-borne avian influenza

Dust particles in poultry houses can exacerbate the spread of highly pathogenic avian influenza (HPAI), with the virus on dust particles remaining infectious for up to 17 hours. By the birds’ activity, it can easily be aerosolized into the environment and, by the ventilation system’s airflow, can be transmitted within the barn and from barn to barn.
