Abstract

The study was conducted on the hypophysis cerebri of 19 buffalo (bubalus bubalis) foetii ranging from 30mm to 630mm in crown-rump length (CRL). The immnoreactive follicle stimulating hormone producing (FSH) cells were observed first time at 190mm CRL and were distributed throughout the lobe except in the lateral regions where the cells were rare. At 240mm CRL the cells were more in the rostro-dorsal region of the lobe. The cells were relatively more in number and were distributed throughout the lobe at 482mm stage. However, the density of the cells was relatively more near the cleft and cells were also seen along the blood vessels at this stage. At 630mm CRL strongly positive immunoreactive FSH cells were mostly observed singly and rarely in small groups of 2-3 cells. The immunoreactive luteinizing hormone producing (LH) cells were first time noticed at 190mm CRL and were distributed singly throughout the lobe. The cells were mainly seen in the rostral region at 240 mm CRL. At 482mm CRL the LH cells were quite clear with strong immunoreactivity.
