Morphometric and Morphologic Studies of The Stomach During Prenatal Development in White Fulani Cattle (Bosindicus).
Abstract
The gross morphologic and histomorphometric changes of the stomach compartments: (rumen, reticulum, omasum and abomasum) were studied by gross and light microscopic methods. The fetuses were obtained from the White Fulani cows slaughtered at the abattoir in Ikpa Community market, Nsukka, Enugu State. The age of fetuses were determined by crown rump length method, while the total volume of the compartments was determined by displacement and flotation method. Grossly, the rumen and reticulum (ruminoreticulum) had smooth mucosal surface and beige in colour. Microscopically, the wall comprised; mucosa, submucosa, tunica muscularis and serosa. The mucosa was lined by stratified squamous epithelium which was divided into larger light staining luminal and smaller dark basal zones in 96-day-old fetus.Finger-like profiles of the basal zone with lamina propria extended into the luminal zone in GD 194 fetus.Theproprial papillae approached the luminal surface in GD 242 fetus. The omasum on the other hand,had a smooth gross mucosal surface, which exhibited longitudinally oriented primary, secondary, tertiary and quaternary laminae microscopically. It was also lined by stratified squamous epithelium which was divided into larger lighter luminal and smaller darker basal zones in GD 96 fetus. The basal zone developed lateral evaginations (proprial papillae) into the lighter zone of the laminae in GD 194 and GD 242 fetuses.The core of the laminae contained inner circular and outer longitudinal layers of the muscular tunic. Grossly,the abomasum, had a mucosal surface covered by slimy mucous material. The abomasal wall displayed primitive folds and by GD 96 fetus, abomasal peak areas were observed on the fold surface. At GD 194, the abomasal mucosal was lined by simple columnar epthelium and gastric pits were present. At the bottom of these pits, outline of glands could be observed. The abomasum was histodifferentiated into lamina propria-submucosa, tunica muscularis and serosa. The luminal mucosal surface was lined by simple columna epithelium. The gross and histomorphomnetric measurements of GD 96-242 fetuses were determined.
