The Histological Structure Of The Crop (Ingluvies) In Poultry

Abstract

This research aims to see the histological structure of the crop in poultry. Animals used were chicken (Gallus domesticus), duck (Anser anser
domesticus), and pigeon (Columba domesticus) each group consists of three animals. Crop tissue of each animal were taken and processed in
microtechnic and stained with Hematoxilin and Eosin (HE), then observed with digital microscope. The results showed that there were the
similarity of the general structures of crop from the three types of these poultry. which consists of the tunica mucosa, tuni ca submucosa, tunica
muscularis and tunica serosa. Lamina muscularis in duck is more obvious than chicken and pigeon. Mucosal gland of duck shaped oval, chicken
shaped rounded, and the pigeons are not found. Tunica muscularis duck arranged longitudinally in the outside dan ci rcular in the inside. Tunica
muscularis duck arranged longitudinally in the inside, and circular in the outside, and tunica muscularis in pigeon just arranged longitudinally.
