The present study was conducted to study histogenesis of thyroid gland in buffalo fetuses (n=11) ranging from 5.2 cm (52 days) to 65.0 cm (220 days) curved crown rump length (CVRL). The parenchyma of thyroid gland comprised randomly arranged undifferentiated mesenchymal cells with large number of blood vessels up to 13.7 cm CVRL (90 days). Initiation of follicular arrangement was observed in some of the developing follicles at 20 cm CVRL (119 days). The resorption vacuoles appeared in the colloid at 28.0 cm CVRL (137 days) and invasion of connective tissue in the parenchyma of gland was observed. Ultimo-bronchial follicles were observed at 25 to 28 cm CVRL (130137 days) and C-cells at 65 cm CVRL (220 days).
