Histological and Immunohistochemistry Studies of Trachea Calcification in the Laying Hens (Gallus gallusdomesticus)

Ahmed Mahdi Al- badri, Asawer Abdul- Jabbar Al-Salman

Abstract: The aim of this study is to detect calcification of trachea and determination its appearance in different age of groups of laying hens.
