The overall least squares means for open period, service period, calving interval, number of service per conception as affected by reproductive disorders were 97.67 ± 3.04 (days), 173.06±5.63 (days), 442.47 ± 8.48 (days), 3.90 ± 0.25 (days), respectively. The lactation order had significant effect on open period and non-significant effect on service period, calving interval, number of service per conception. The effect of reproductive disorders was significant on open period, service period, calving interval, number of service per conception. The per cent increase in open period, service period, calving interval due to reproductive disorders were 15.92 to 91.68, 56.60 to 94.62 and 10.36 to 39.33 per cent, respectively.
