In dairy cattle, endometritis is one of the conditions of highest impact on dairy cows. It reduces fertility and increases the production costs. The aim of this study was to observe the effect of endometritis in crossbred cows at 32 ± 2 days postpartum on the reproductive performance of crossbred dairy cows. In this study 24 cows were selected based on polymorphnuclear cells (PMN) scoring by cytobrush and divided into 2 groups. In group I- the 12 cows positive for endometritis were included, whereas in group- II, the cows which were found negative on cytosmear or showing lower than 5 % PMN cells in uterine cytology were included and kept as control group. Statistically significant difference was found (p<0.05) between all reproductive parameters of endometritis affected and healthy cows. It was found that the mean days required for exhibition of first postpartum estrus, number services per conception, first service conception rate and days open for first group were 76.67 ± 5.16, 4.16 ± 0.42, 8.33 % and 162.67 ± 8.07 days, respectively. The corresponding values for group II, were 57.83 ± 3.38 days, 2.17 ± 0.34, 33.33 % and 100.67 ± 8.42 days, respectively. In conclusion, we determined the effect of endometritis average measured in days, affecting the reproductive parameter and increases the cost of raising the cows. Therefore efforts should be made in prevention, early identification and control programs to prevent the losses to dairy industry.
