Retention of the fetal membranes (RFM) is still a considerable problem in bovine re-production. Forty normally calved buffalo-cows aged 4-7 years did not expeled fetal membrane more than 6 hours was used in this trials. Out of their forty buffalo-cows (n=20) were given 4 ml of synthetic oxytocin intramuscular (1 m = 10 i.u. synthetic oxytocin). This was repeated every 30 minuts for up to six treatment or until the membranes did come away . The remain cows (n=20) received 4 ml. saline used as controls. In the analysis of the herd over about one year period. There was a recorded awerage 12.42% RFM (40/322), moreover the incidence of postpartum metritis was less in the treated group (10% vs 30% in the controls). The majority of treated buffalo-cows need four injection of synthetic oxytocin, but there was a range from two to six injection.
It could be concluded that the incidence of RFM could be minimizes by using i/m injection a synthetic octapeptide at six hours on-words.
