| Abstract | ||||
| The histological development oi the goat stomach during the ioetal dhd early neonatal period was studied. At B cm CVR length the ruminal and reticular mucosae were smooth and covered with stratified columnar pithelium, how- ever the omasal mucosa was thrown into various folds. The abomasum beared a longitudinally folded mucosa and was lined with pseudostratified columnar epithelium. The prlmordie oi the reticular folds were observed as early as 22 cm CVR length. However. the primary elements oi the omasal laminae were pronounced at 25 cm CVR length. The gastric glands started to develop at 25 cm CVR length. The parietal, chief, and mucous neck cells could be recognized in foetuses of 33 cm CVR length. The gastric epithelium domonstrated abund- ant mocopolysaccharids during the early periods oi intrauterine liie. However, at the end of gestation and in newborn goats the gastric epithelium contained much fewer amount oi these materials. In 3 day-old gbats, the gastric mucosae simulated that oi afult animals. | ||||
