Abstract

The present study was conducted on five healthy indigenous male turkeys at the first year of their age and live weight was (4715 ± 43.3 gm) collected from the center of Diwanyia city, our need to have a base line data on the respiratory system of this abundant species of bird in Iraq. It is expected that this work will provide a pivot for future research and subsequent clinical application as regards the biology of the turkey.After birds preparation the trachea dissected out and washing by normal saline solution (0.9% Nacl), then were fixed immediately in 10% formalin, then get ready for routine histological processing.Trachea was lined by respiratory epithelium (ciliated, pseudostratified columnar epithelium) with simple branched tubular mucous glands and goblet cells. Laminapropria-submucosa of the trachea was supported by hyaline cartilages and comprised of loose connective tissue, with large bundles of collagen fibers.
