The heat period of buffalo is Correct Answer 12 - 36 h

The heat period of buffalo is 12 - 36 h.
The heat cycle of the female lasts from 18 to 21 days. The first stage is called proestrus. It begins with mild swelling of the vulva and a bloody discharge.
The mean length of the oestrous cycle is 21 days, with greater variation than observed in cattle. The signs of oestrus in buffalo are less overt than in cattle and homosexual behaviour between females is rare. The duration of oestrus is 5 - 27 h, with ovulation occurring 24 - 48 h (mean 34 h) after the onset of oestrus.
