This study was performed on 64 Iraqi female buffaloes suffered from Retained fetal membranes in-Karbala province on the period from December 2012 until December 2013 with different ages.

These animals were divided randomly into two groups.

While the other “control group” (28) buffaloes were injected with (5 ml) distilled water also on day (14) postpartum.

The response in the (GnRh) treated group (decrease of the first postpartum estrus and decreased open days) records 52.3 ± 16.4 days for the first postpartum period compared with 74.7 ± 21.8days of control group.

While service per conception showed1.9 ± 1.2 to the GnRh treated group compared to 2.4 ± 1.6 of the control group.

The days open in the GnRh treated group was 88.6 % ± 12.5 compared to 123.2 ± 25.4 in the control group.

The statistical analysis showed that GnRh treated group showed significant shorter postpartum period than control group, in case of first postpartum period and open days.
