The present study was performed on six healthy early neonatal buffalo calves. The age of buffalo calves was estimated by their dentition. In early neonates, the lymphoid tissue was observed to be present as diffuse lymphoid tissue mostly below tunica mucosa. Later, with increasing age, solitary lymphoid nodules were observed at some places along with diffuse lymphoid tissue at anti-mesenteric circumference. However, the diffuse lymphoid tissue was also found to invade the epithelium forming dome like structure. With subsequent advancement of age (in four weeks old neonates), the mucosal glands were clearly observed to enter the submucosal region surrounded by the diffuse lymphoid tissue, forming lymphoglandular complexes (LGCs).

The present study was conducted on 15 buffalo foetuses, from 11.5 cm curved crown rump length (CVRL) to 100 cm CVRL (full term) and were divided into three groups based on their CVRL.On 80 days, villous epithelium was devoid of acidic mucopolysaccharides. However, at 148 days, connective tissue framework around developing accumulations of few lymphocytes was moderately alcianophillic. At 231 days, lymphoid follicles and capsule were moderately positive for neutral mucopolysaccharides and glandular epithelium showed increased activity for presence of both acidic and neutral mucopolysaccharides. At 299 days, the Follicle associated epithelium (FAE) over dome of lymphoid follicle was devoid of goblet cells. [ABSTRACT FROM AUTHOR]
