Abstract

The present research was elucidated on the morphogenesis of mammary gland of buffalo during prenatal development. Total of 16 foetuses ranging from 1.2 cm (34 days) to 108 cm CVRL (curved crown rump length) (317 days) were used for study. The study revealed that mammary line was first observed at 1.2 cm CVRL (34 days), mammary hillock at 1.7 cm (37 days), and mammary bud at 2.6 cm CVRL (41 days) foetuses. Epidermal cone was found at 6.7 cm CVRL (58 days) whereas primary and secondary ducts were observed at 7.4 cm CVRL (62 days) and 15 cm CVRL (96 days), respectively. Connective tissue whorls were reported at 18.2 cm CVRL (110 days) and internal elastic lamina and muscle layers at 24.1 cm CVRL (129 days). Lobules were observed at 29.3 cm CVRL (140 days), rosette of furstenberg at 39.5 cm CVRL (163 days), and keratin plug at 45.5 cm CVRL (176 days) foetus. Primordia of sweat and sebaceous glands around hair follicle were seen at 21.2 cm CVRL (122 days) of foetal life. Differentiation of all the skin layers along with cornification was observed at 69 cm (229 days) in group III foetuses.
