Respiratory diseases of turkeys - part one

摘要

Respiratory conditions are one of the most serious groups of diseases affecting turkeys and are continuing to cause heavy economic losses by increased mortality rates, increased medication costs, increased condemnation rates, drops in egg production,reduction of egg shell quality, and decreased hatchability. Several pathogens are incriminated as the possible cause of respiratory diseases either alone (mono-causal) or in synergy with different other micro-organisms (multi-causal) or accompanied by non-infectious factors such as climatic conditions and management related problems (Table.1).
