Morphological comparison of proventricular and gizzard in starling birds Sturnus vulgaris and pigeon Columba livia

Author(s): Suhaib AH AL-Taai
Abstract: The current study aimed to investigate the stomach of two species starling Sturnus vulgaris and pigeons Columba livia. The experiment was included 10 birds, it is distributed in two equal groups. Ages of birds were average range 6-9 months (adult age). The observations was appeared the stomach in both the species, divided into 2 chambers. The results were showed the first stomach is called proventriculus. It's characterized elongated in shape and expansion of the esophagus, located forward the gizzard to posterior at the esophagus in both species. Our study was included some gross findings differentiates in two kinds. However, the proventriculus in starling S. vulgaris was characterized a cylindrical-like and had gastric papillae which it's appeared from external surface of proventriculus with long isthmus. Whereas our results in pigeon C. livia, the glandular stomach was tubular in shape and no protrudes of gastric papillae during outer wall of it with short isthmus. Either gizzard was spherical in shape of starling and fusiform-like in pigeons, but it was thin muscular wall and clear at fatty tissue with pale color comparatively with pigeon, because the starling birds were represented at omnivores depend on the nutrition adding to the grains. In the pigeons, the gizzard had amount of adipose tissue it's covered most the external wall of it. The situation of gizzard in pigeon was situated posterior toward proventriculus and had thick muscular wall with dark-red in color according to nature of diet, facilities of the grinding grain for indigestion, therefore the pigeons were considered from granivorous. Also the study was included anatomical statics measurements, length, weight and volume in addition to weights of the birds. Where the study was recorded no significant data mean between species of birds proventriculus and gizzard (table 1).
