Abstract

This research aimed to compare the morphology and carbohydrate content of parotid and mandibular glands of goat, cat and pig (herbivore, carnivore and omnivore). The microscopic observation was done using histochemical method with hematoksilin eosin (HE), alcian blue (AB) pH 2.5 and periodic acid Schiff (PAS) staining methods.The results showed that the parotid and mandibular glands consist of acinar cells and ducts. The parotid gland of goat and pig were serous while mixed in the cat. The mandibular gland of goat, cat and pig were mixed type. The acinar of mandibular gland is composed of serous and mucous cells in which the mucous cell predominates. The AB and PAS stain showed weak to high concentration of acid and neutral carbohydrates found in the mucous cells of mandibular gland. However, these carbohydrates were not found in the serous cells of both glands, while acid carbohydrate was found in the parotid gland of cat. The present result suggested that the carbohydrates in the saliva of the goat, cat and pig might be produced mainly by the mucous cells. Keywords: parotid gland, mandibular gland, PAS, AB pH 2.5
