Avian Metapneumovirus (aMPV) in Chickens and Turkeys

Avian Metapneumovirus (aMPV) infections may cause disease in turkeys and chickens of all ages. The disease is found in most countries in the world.

Disease overview

AMPV targets not only the respiratory tract but also the reproductive tract, causing mainly a respiratory disease in the infected birds and also drops in egg production in layers and breeders.

The economic impact of aMPV is mainly due to:

• Poor performance and mortality due to respiratory disease in meat turkeys and broilers
• Egg production losses in layers and breeders

The negative effects of an aMPV infection can be successfully controlled by vaccination and implementing sound biosecurity principles.
