Abstract
The study aimed to describe the histological features of Pancreas and Duodenum in Common Moorhen (Galinula choropus), Barn Owl (Tyto alba) and common Budgie (Melopsittacus undulatus). Compare histological parameters of Pancreas and Duodenum among these birds. In the current study, Histochemistry of Pancreas showed that the use of Masson trichrome staining in Owl’s pancreas shows presence of collagen fibers in the septa between lobes and also within the capsule surrounded the organ. while this stain shows positive reaction only in capsule in Moorhen and Budgie bird pancreas. Owl bird and budgerigar bird pancreas show positive reaction to Alcian blue stain. Alcian blue –PAS mixture in Owl pancreas shows the presence of mucin around the interlober ducts and in the exocrine portions. Moorhen bird pancreas has more mucin in the interlober ducts and exocrine portion than that of Owl’s pancreas. Histochemistry of the duodenum by the use of Masson Trichrom staining in Budgie bird showed the presence of collagen fibers in the serosa and the core of the villi and in the submucosa, moorhen bird duodenum shows the presence of collagen fibers in submucosa as well as in serosa and within muscularis layer. While Alcian blue in Budgie bird show that presence of acidic sulphated mucin within submucosa and muscularis and serosa. Alcian blue –PAS mixture stain showed the duodenum of the three birds expresses the goblet cells positively reacted to this stain due to the presence of acid mucine within.
