Studies on oestrous symptoms of buffalo heifers

Studies based on frequent daily observations for nine months, encompassing 92 oestrous periods in 31 Murrah buffalo heifers, revealed that the vulval discharge of clear mucus in varying quantities in a recumbent animal, even in silent heat, was the most reliable single sign of heat in buffalo heifers. Of the other signs observed, wall walking (segregation) and bellowing confirmed oestrus in 83.69% and 80.43%, respectively, while placid response of the animal to the placing of palm of hand on the rump ano response to light massage of vulval lips were seen in 86.95% and 83.69%, respectively. Based upon the degree of manifestation of oestrous symptoms, intensity of oestrus was divided into four categories. Four daily observations of the animal for important symptoms of heat a few days before the expected oestrus could make oestrous detection a sure success.
