The development of omasum in fetuses between 60, 90, 120 days of gestation and neonates of Korean native goats was investigated by fight; scanning electron microscopy. The results were summarized as follows : 1. In the 60-day-old fetuses, the stomach was developed and differentiated into four compartments of rumen, reticulum, omasum, and abomasum. The mucosa of the omasum was thrown into folds which appeared to be three or four different orders of large, medium, small, and smallest laminae. 2. In the 90-day-old fetuses, the omasal laminae had increased greatly in length and cores of omasal laminae were invaginated laterally. 3. In the 120-day-old fetuses, the wall of the omasal laminae had increased in length and the lamina epithelialisis had slightly increased in thickness. The lateral invaginations at the dark zone had increased in length and depth. The tunica muscularis increased only slightly in thickness particularly within its inner circular layer. 4. In the neonate, the muscularis and the omasal laminae had increased in thickness. The lateral invaginations of the dark zone were observed in the first, second and third order of omasal laminae. 5. Scanning electron microscopic studies : In the 90-day-old fetuses, numerous microvilli and microridges were observed on the luminar surface of the omasal mucosa. The omasal papillae were already formed at 120 days of gestation. In the I20-day-old fetuses omasal papillae liked nipple shape. In the neonate, the omasal papillae liked the thumb.

The development of reticulum in fetuses between 60, 90, 120 days of gestation and neonates of Korean native goats was investigated by light, scanning electron microscopy. The results were summarized as follows; 1. In the 60-day-old fetuses, the stomach was developed and differentiated into four compartments of rumen, reticulum, omasum, and abomasum. The reticular epithelial layers were differentiated into two zones; a small dark basal and a large light luminar zones. The wall of reticulum resembled that of the rumen except that the mucosa was in the cranio-dorsal region of the reticulum. 2. In the 90-day-old fetuses, the light luminar zone of the reticulum was about 10-16 times thicker than the dark zone. The outlines of the reticular ribs were visible. 3. In the 120-day-old fetuses, the wall of the reticlum had also increased in thickness. The reticular mucosa exhibited an irregular luminar surface and the invaginations had differentiated into large regularly arranged ones separated by 3-5 and small irregularly arranged ones. 4. In the neonate, the luminar surface of the reticular mucosa demonstrated clear furrows, at which the superficial cells of the light zone had undergone degenerative changes. 5. Scanning electron microscopic studies; In the 60-day-old fetuse, numerous microvilli were observed on the superficial epithelial layer of shape or dome like at 120 days. In the neonate, the reticular papillae liked the little finger.

The development of rumen in fetuses between 60, 90, 120 days of gestation and neonates of Korean native goats was investigated by light, scanning electron microscopy. The results were summarized as follows; 1. In the 60-day-old fetuses, the stomach was developed and differentiated into four compartments of rumen, reticulum, omasum, and abomasum. The ruminal epithelial layers were differentiated into two zones; a small dark basal and a large light luminar zones. 2. In the 90-day-old fetuses, the light luminar zone of the rumen was 6-12 times thicker than the dark zone. 3. In the 120-day-old fetuses, the wall of the rumen had increased in thickness, and its the mucosa was still smooth. Several undulations of various depths involving the basal zone, basement membrane and lamina propria were observed at irregular within the light zone. 4. In the neonate, the wall of the rumen had increased in thickness and the luminar surface had become wavy due to the appearance of several shallow furrows in the luminar surface of the epithelium especially between the tips of the relatively more developed undulations. 5. Scanning electron microscopic studies: In the 90-day-old fetuses, numerous microvilli and microridges were observed on the superficial epithelial layer of the rumen. The ruminal papillae were already formed at 120 days of gestation. In the 120-day-old fetuses, the ruminal papillae formed short dome-shape. In the neonate, the ruminal papillae formed pebble-shape or short finger like.

The development of abomasum in fetuses between 60, 90, 120 days of gestation and neonates of Korean native goats was investigated by light, scanning and transmission electron microscopy. The results obtained were summarized as follows ; 1. The abomasum wall appeared to be differentiated into the epithelium, lamina propria, muscle layer, and serosa at 60 days of gestation. The epithelium was stratified columnar and these nuclei were located near the apical two thirds portion of the cell at 60 days of gestation, and then transformed into simple columnar epithelium with the flat basal nuclei. 2. The inner circular and outer longitudinal muscle layers were observed at 90 days of gestation and the blood vessels had become quite well developed as various arterioles, venules and capillaries of different size during this age. 3. Gastric pits were seen at 90 days of gestation and continued gradually to increase depth during gestation. 4. The mucous, parietal and chief cells appeared in epithelium at 90 days of gestation and continued gradually to increase in number during gestation. In 120 days fetuses and neonates, muscle layer had become very thickeness. 5. Scanning electron microscopically, the inner surface of the abomasum already consisted of wavy spiral folds which had many fine wrinkles at 60 days of gestation. In 90 day old fetuses, each spiral fold was enlarged and its surface was tended to be split into many straight longitudinal ridges and among these ridge were found shallow grooves, At 120 days, the subdivided swellings of ridges were progressively complicated in shape. In the neonates, the inner surface was flat and holed with many gastric pits. 6. Transmission electron microscopically, the epithelium was straified columnar and these nuclei were irregular shape at 60 days fetus. The parietal, chief and mucous cells were observed in 90 day old fetuses and continued gradually to increase in number during gestation. 7. The development of the abomasum was relatively slow at early stages, it was accelerated greatly in the last of gestation.

The development of esophagus in fetuses between 60, 90, 120 days of gestation and neonates of Korean native goats was investigated by light, scanning electron microscopy. The results were summarized as follows; 1. The esophageal wall appeared to be differentiated into the epithelium, lamina propria, tunica muscularis and tunica adventitia at 60 days of gestation. The esophageal epithelium was stratified cuboidal at 60 days, being transformed into stratified squamous epithelium at 90 days, and completely transformed into squamous epithelium an 120 days. 2. In scanning electron microscopy, the longitudinal furrows and ridges appeared on the epithelium of the esophagus of the fetuses at 60 days of gestation. The longitudinal furrow became deeper and microplicae appeared in 90-day-old fetuses. The transverse and longitudinal folds appeared on the epithelial surface of esophagus and the esophageal epithelium started to be keratinized in the neonates.
