This study was conducted to evaluate the influence of various postpartum disorders on subsequent reproductive performance in Iraqi cow buffaloes. The data were collected from 172 buffaloes within private dairy buffaloes herd. In this study, the diagnosis and treatment of the affected cases with postpartum disorders (Retained placenta, puerperal metritis, uterine prolapse and vaginal prolapse) contributed in the data collection based on the parity, calving time and reproductive parameters (days to first estrus, open days, service per conception, intervals between estrus and calving interval). Cow buffaloes were divided according to their postpartum disorders into 5 groups: first group (healthy), second group (retained placenta), third group (puerperal metritis), forth group (uterine prolapse) and fifth (vaginal prolapse). The results of this study showed that a total of 74.42% of the cow buffaloes had normal post-partum and open days 121.9 days with resumed ovarian cyclic activity within 77.41 days, increased incidence of G2, G3, G4 and G5 were 9.88, 6.97, 6.97, 5.23 and 3.48%, respectively. Open days were significantly longer in buffaloes in groups 2, 3, 4 and 5 compared to healthy group. In conclusions, early postpartum disorders manifested by increased days to first estrus, calving interval, days open and service per conception were longer than healthy cases in the Iraqi cow-buffaloes.
