Ten abomasal specimens were taken from male awasi sheep as well as from the male black bucks slaughtered at Mosul
slaughter house. Comparative histological and morphometrical studies were carried out on the mucosa of pyloric region of
both animals. The depth of gastric pits, the extension of pyloric glands and the thickness of muscularis mucosa were
progressively increased distally in both animals, the results is a steady increase in the total thickness of the mucosa proximo –
distally in both of studied species. It was noticed that the average heights of surface epithelial cells, the pits lining cells and the
pyloric glandular cells o f the goat were more than their counterpart cells of sheep. It was also observed that the number of
glands were relatively higher than the number of gastric pits in the definite surface area which indicates that some pits may
receive more than one gland in both of the studied species.
