The animals were served at the time of oestrous observed by the owner. Progesterone levels at day 24 after AI was used to predict the conception. Ten out of nineteen animals were pregnant which was indicated by progesterone levels above 1.0 ng/ml. Six animals were non-pregnant that progesterone levels were below 0.5 ng/ml. Three animals showed progesterone levels between 0.5-1.0 ng/ml which were indicated as doubtful cases. Five out of ten pregnant buffaloes were calved and one animal was not pregnant while the others were aborted at days 58, 86, 93 and 100 after AI. Progesterone levels in five pregnant animals were consistently high with the average value ranging from 1.07+-0.18 to 2.31+-0.47 ng/ml. Those abortive animals showed progesterone levels kept high before the day of abortion and consequently cycling change after abortion. Oestrone sulphate levels of pregnant and abortive buffaloes at day 20 after AI were 149.24+-97.03 and 55.30+-12.12 pg/ml, respectively. The levels in pregnant group were significantly higher than the abortive group at day 114 after AI, with the value of 155.58+-28.77 and 49.31+-16.76 pg/ml, respectively. Oestrone sulphate levels in pregnant group was gradually increased and reach to 1,232.00+-249.46 pg/ml by day of 205 after AI. The use of progesterone levels to oestrous confirmation and early pregnancy diagnosis was applicable. Consequent pregnancy confirmation by oestrone sulphate levels at day 100 after AI was feasible.
