The tissues from the small intestine containing jejunum were collected from six young goats and processed for scanning and transmission electron microscopic studies. The jejunum villi were of different heights having a broad base with tapering to blunt ends. The surface of the villi showed slight corrugation in the initial part of the jejunum. These corrugations were very faint in this region and also showed orifices for goblet cells. The caudal segments of the jejunum showed some structural changes in the form of more prominent corrugations on the villi surface. The villi surface showed orifices with irregular boundaries for openings of goblet cells in between the dense areas of the microvilli. Whereas the transmission electron microscopy revealed that the epithelium of the jejunum was of a columnar type having goblet cells and no Paneth cells were observed in the villous part of the jejunum. A very few goblet cells were interspersed in between the columnar cells. The glandular epithelium consisted of different cell populations consisted of columnar, Paneth, endocrine and goblet cells.
