This NebGuide discusses the most common respiratory infections in poultry, and includes steps to diagnose, prevent, and treat each.

Small poultry flocks are susceptible to a number of respiratory infections. Some of these produce extremely mild illness while others may result in a high number of deaths.

Regardless of whether birds are raised for meat, eggs, breeding or show purposes, respiratory infections result in decreased performance. They may also disqualify a bird for show, and pose disease hazards for other poultry on the same premises.
