AB  - The syndrome of retained placenta is an important problem that affects cows in the farms of Iran and other countries. In a study on the cows with retained placenta, the effect of prostaglandin injections on the mean time of placental expulsion was studied. Cows with retained placenta (n = 150) were divided randomly to the three groups of A, B and C (n = 50). In the group of A, 25 mg PGF<SUB>2 </SUB>, (Lutalyse, Upjohn Ltd) were injected to the cows at the 5, 6 and 7th days of postpartum. In the group of B, the same dosage of PGF<SUB>2 </SUB>, were injected to the cows at 8, 9 and 10th days of postpartum. In the group of C, PGF<SUB>2 </SUB>, were not injected to cows and the natural time of placental expulsion in this group recorded as the control time. Mean±SD days of placental expulsion was calculated in each group and statistically compared with control group. Significant statistical differences were not observed between groups of A (13.2±3) and C (13.6±3). But significant statistical differences were observed between groups B (10.3±1) and C (13.6±3) (p&lt;0.05). These results indicated that PGF<SUB>2 </SUB> injection to the RFM cows could reduce the expulsion period of the retained placenta at least 3 days, when administered at day 8 onwards, but had no significant effect before day 8.
