ABSTRACT

Rostami A, Goli M, Karami H., Effect of vitamin E and selenium with oxytocin and/or PGF2α on incidence of retained fetal membranes in Holstein cows, Onl J Vet Res.,  21(1):33-39, 2017. Effect of supplementing unassisted-calved Holstein cows with intramuscular injection of vitamin E and selenium (Se) with or without oxytocin (OT) and/or a PGF2α analog cloprostenol minutes after calving, on incidence of retained fetal membranes (RFM), and parity of cows is described. Groups of 22 cows each were injected intramuscularly (IM) 20 ml VitE + Se, 20ml VitE + Se with 50 IU OT, 20ml VitE + Se with 500µg  cloprostenol, 20ml VitE + Se, with 50 IU OT and 500 µg of cloprostenol. Controls were injected IM with 5ml sterile saline. All injections were given IM by the same person within a few minutes after calf delivery. Cows were observed for 12 h after calf delivery and those that retained their fetal membranes for more than 12 h after calving were considered to suffer from RFM. We find that intramuscular administration of OT and/or PGF2α in combination with VitE and Se in a few minutes after unassisted calving did not reduce the incidence of RFM within 12h in Holstein dairy cows: Supplementing unassisted-calved Holstein cows with intramuscular injection of VitE and Se in combination with OT and/or a PGF2α analog (cloprostenol) a few minutes after calving is not affected by parity of dam or incidence of RFM (P ≥ 0.05). Also no significant decrease in the incidence of RFM was found in treated cows compared with non-treated controls (P ≥ 0.05).

Key-Words: Retained Fetal membranes, Vitamin E, Selenium, Cloprostenol, Holstein Cows.
