Abstract

This study aimed to maximize the acquaintance on the morphology of the gizzard of the Laughing Dove (LD) and Rock Pigeon (RP). Gizzards of ten birds of each species were used for gross anatomy, scanning electron microscope and light microscope. The gizzard was biconvex lens in shape with rhomboidal circumference in both birds and with more oval in LD. The gizzard length constituted 55.41% in LD and 53.60% in RP of the total length of the stomach. The gizzard extended from the level of the 5th intercostal space to terminat12.25±1.18, 17.27±0.88mm behind the last rib and 10.90±0.70, 19.48±0.49 mm infront of the vent in LD and RP respectively. The midway section through the thick muscles in the dorsoventral plane parallel to the tendinous center showed that the gizzard lumen appeared nearly S-shaped at both birds with 2 invaginations at caudal end of the lumen toward the caudoventral blind sac of RP. Another midway section through the thick muscles and tendinous center in the dorsoventral plane explained that the gizzard lumen was nearly elliptical in RP and rectangular in LD surrounded in both sides by semi ellipsoid thick muscles. By SEM, the cutical folds of the gizzard resembled bundles of rods in LD and appeared as group of blunt projections in RP. The epithelial lining of the tubular glands was columnar with large rounded or oval nuclei and deeply stained basophilic cytoplasm.
