Golia M, Abdolmohammadib AR., Effect of oxytocin on incidence of retained fetal membranes in Holstein cows with dystocia, Onl J Vet Res., 19(8): 530-538, 2015. Effect of oxytocin on the incidence of retained fetal membranes in Holstein cows with dystocia, parity and season are described. 149 primiparous and multiparous Holstein cows with dystocia received a single intramuscular injection of 50 IU, 5 ml immediately after calf delivery. Controls received no oxytocin. Cows were monitored 24 h after delivery for fetal membrane retention. There was no significant difference in incidence of fetal membrane retention between treated and controls. Cows were classified by parity of 1, 2 and > 3 and 4 according to season. There was no significant effect of parity or season on the incidence of retained fetal membranes or of oxytocin treatment x parity, x season, parity x season or oxytocin treatment x parity x season on incidence of retained fetal membranes. Results suggest that an intramuscular injection of oxytocin immediately after calf delivery in any parity or season does not affect incidence of retained fetal membranes in Holstein cows with dystocia.
