This study was conducted to investigate the normal maturation process of erythriod lineage in bone marrow of adult Iraqi goat. Five healthy adult male goats aged 26-34 months were chosen for this study. A simple technique used for obtaining marrow from goats, employs sedation  xylazine hydrochloride 0.1 mg/kg body weight. Skin incision was made over the iliac crest. Marrow was aspirated with a syringe and smears were made directly.  Erythropoiesis in the bone marrow of an adult goat included a successive morphological alteration resulting in production of erythrocytes. The lineage of erythroid of bone marrow of adult goat comprises; Rubriblast , Prorubricytes, Rubricytes, Metarubricytes, and Reticulocyte. The final cellular lineage of the erythropoiesis bone marrow of the goat was the formation of non-nucleated erythrocytes.
