A total of 1434 inter-insemination lengths from 767 buffaloes (241 heifers and 526 buffaloes) pertaining to the period of 1975-76 and 1976-77, were calculated and analysed. The inter-insemination lengths were 36.74 and 37.74, 35.17 and 25.96, 12.37 and 15.62, 6.38 and 7.93, 4.03 and 3.85, 2.36 and 3.37, 1.37 and 3.37 and 1.08 and 2.16 per cent in the ranges of 1-20, 21-40, 41-60, 61-80, 81-100, 101-125, 126-150 and 151 & above days range in buffaloes and heifers, respectively. The aberrations in the oestrous cycle observed in buffaloes and heifers were 17.61 and 18.31 long oestrus/delayed ovulation (1-4 days); 10.42 and 11.74% very abort oestrous cycles (5-8 days); 11.17 and 10.33% mid cycle oestrus (9.12 days); 11.74 and 7.04% short oestrous cycles (13-17 days); 38.26 and 45.07% normal oestrous cycles (18-24 days) and 10.80 and 7.51% long oestrus cycles (25-28 days).enOBSTETRICS AND GYNAECOLOGYA STUDYThesis
