Abstract:
Present study was conducted on the exocrine part of pancreas of twenty four apparently healthy chabro chickens irrespective of sex. The birds were divided into 0 day, 30 days, 60 days and 150 days age groups. The pancreas of chabro chicken was covered by very thin fibrous connective tissue capsule. The reticular and collagen fibers became coarser in the capsule with the advancement of the age of the birds. Very fine to fine reticular fibers generally encircled one third to two third part of the individual acini at the age of 0 day group but as the age advanced most of the acini were completely encircled by relatively coarser reticular fibers. The lymphatic aggregations were frequently observed in the stromal tissue and their occurrence was relatively more in the splenic lobe. The bipolar staining character became prominent and as age of the birds advanced the basophilic staining zone increased in cell cytoplasm. One to two centroacinar cell were found in the central part of acini. The intercalated ducts were lined by the simple squamous epithelium, intralobular ducts with squamous to low columnar and interlobular duct with simple cuboidal or simple columnar epithelium. The lumen of most of ducts was filled with eosinophilic secretory products.
