Sixty-six dairy cattle were induced to calve with dexamethasone treatment at 5 d prior to expected time of calving. Each animal was assigned randomly to one of two treatments, saline (2 ml) or PGF2a (10 mg), which were administered within 1 h postpartum. With the saline treatment, 90.5 % of the animals had placental retention, whereas only 8.8 % of the PGF2a-treated animals had placental retention. The PGF2a-treated cows released the fetal membranes in 7.4 t 1.35 h postpartum, whereas the saline-treated cows released the membranes in 98.3 2 10.93 h postpartum. These data demonstrate that treatment with PGF2a within the immediate postpartum period is effective (P
