The observations on oestrus symptoms and fertility were recorded on 71 Murrah buffaloes. Standing to mount, restlessness and bellowing in order were the characteristic oestrous symptoms. The type of oestrus was weak in 73.24%, moderate in 25.35% and intense in 1.41% of the buffaloes. The 45 days non-return rate was 50.78% but the conception rate was only 29.58%. The parity, onset of oestrus and oestrus signs had no significant association with conception. The conception was directly proportional to the degree of tonicity of uterus.
