摘要: The aims of the present study were to further examine efficacy different doses and routes R-cloprostenol administration on parturition response in sows. Fifty crossbred multiparous sows (Landrace x Yorkshire) with an average parity number 4.7 +/- 2.4 allocated induce farrowing by one following treatments: Group I (control, n = 10) injection normal saline 2 ml administered intramuscularly (i.m.); II (n 75 microg i.m. (at 7 AM); III AM) together 10 IU oxytocin (24 h after R-cloprostenol) i.m.; IV 37.5 into perivulva region; V region parameters: pre-farrowing maternal behaviour, restless or interval, expulsion intervals, duration farrowing, total piglets born, litter birthweight, umbilical cord morphology degree meconium staining record. There no significant differences among groups for behaviours. In all sows, behaviour was not observed. effect (10 IU, i.m.) percentage groups. route dose piglet born alive, stillbirth, mummy birthweight. No effects found interval duration. conclusion, results demonstrated that a half (37.5 microg) effective inducing as full recommended (75 neck (i.m.) behaviour.
