Abstract:
The study was conducted on 36 developing abomasum of healthy and normal embryos/ foeti of goat. Embryos/foeti were assigned into three group viz. group I (0-50 days of gestation), group II (51-100 days of gestation) and group III (101-150 days of gestation). The wall of glandular stomach, the pyloric part, was composed of epithelium, pleuripotent blastemic tissue and serosa upto 44 days of gestation. Tunica muscularis became separable at 46 days of gestation. The epithelium was stratified type up to 50 days and gradually changed to pseudostratified columnar to simple columnar type from 76 days of gestation. However, stratification of the epithelium was noticed at few places till term. Thin strands of muscularis mucosae were observed at 82 days of gestation. Gastric pit, the fore runner of gastric gland was reported first at 70 days. The body of the gastric glands were very short. Process of proliferation, coiling and lumen formation were faster in pyloric gland. The cells of pyloric gland contained undifferentiating, mucous secreting and sporadic parietal cells. Well differentiated mucous secreting cells were noticed at 121 days of gestation. Reticular, collagen and elastic fibers came into sight at 38, 100 and 100 days of gestation, respectively. Combined thickness of lamina propria, muscularis mucosae and submucosa and tunica muscularis was more in pyloric gland region than other region of the abomasum.
