502			_aIn this project the main objective was to determine the oestrus activity of buffaloes during low breeding season. Out of six buffaloes 3 showed oestrus and out of these 2 repeated oestrus cycle. Both the primary and secondary symptoms of oestrus were clearly visible at oestrus. Length of the oestrus cycle was observed as 21.5 days with the average oestrus period 30.8 hours. The mean progesterone concentration in cyclic buffaloes on the day of the oestrus cycle (d=0)was 0.09 ng/ml and the highest serum progesterone concentration were observed on 16th day of oestrus cycle. In the non cyclic buffaloes the progesterone concentration remained around 1 ng/ml throughout the study. At the onset and the end of the oestrus the concentration of luteiningzing hormone was 3.9 ng/ml. Whereas at the beginning of standing heat average luteinizing hormone (LH) concentration 3.8 ng/ml. The surge of luteinizing hormone (LH) was 14.4 ng/ml observed. The average time of LH surge was 17.6 hours after the onset of the oestrus. End of oestrus time of following LH surge was 17.2 hours.
