Subject Areas : Journal of Large Animal Clinical Science Research(JLACSR)

Abstract :
Lingual salivary glands in domestic birds are located in the connective tissue under lingual epithelium with separated acinar forms. These glands are tubulo-alveolar type that including acidic sulfate carbohydrates and neutral compounds in broiler chicken. For this study, the specimens prepared of various lingual regions of 4 mature and healthy domestic goose and then fixed in 10% buffered formalin and performed various preparation tissue process on the specimens, investigated preparation serial sections with 5 µ thickness by hematoxylin and eosin (H&E), periodic acid Schiff (P.A.S) and alcian blue (AB) (PH=2.5) staining methods. The results of this research indicated that these glands were composed of mucous and serous acinars and tubulo- alveolar type. The most of this acinar were mucous type, P.A.S and AB positive. The results showed that mucous cells of this acinar were composed of natural and acidic sulfate carbohydrates that this acidity being due to the presence of carboxyl group. The results of this study did not show difference in type and structure of salivary gland in male and female sex.
