  • Total of 38 buffalo fetuses were used in the present study and their CRL ranged from 0.9 cm to 80.0 cm CRL. In buffalo five pharyngeal pouches were noted at 0.9 cm CRL (26 days). The third pharyngeal pouch showed a common primordium for parathyroid III and thymus at 1.2 cm CRL (28 days). At 2.5 cm CRL (40 days) parathyroid and thymic primordia lost their connection with the pharynx. Thyroid primordium noted as a median diverticulum of the floor of the pharynx at 1.2 cm CRL (28 days). At 2.5 cm CRL (40 days) thyroid primordium showed two distinct lobes and they were connected by unpaired isthmus. At 19.5 cm CRL (115 days) formation of thyroid follicles as well as follicular epithelium was began and thyroid was highly vascular at this stage. At 31.0 cm CRL (143 days) thyroid follicles and follicular epithelium were distinct. At this stage colloid substance was characteristically seen in thyroid glands of buffalo. Many reticular fibers were also reported between the follicles at this stage.
