The main effect of synchroniz ation of parturitions in gilts and sows in group after PGF(2 alpha). (Clopr ostenol((R))) can get a higher perfection after an additionally injection o f long-time Oxytocin analogue Depotocin((R)). After Depotocin((R)) the onse t of parturition is more concentrated than without them or with only a sing le injection of natural Oxytocin. In the average the length of parturition is reduced about 50%. In sows there is no dependence to their body weight a nd their number of litter. Following treatment is recommendable for gilts a nd sows: 1 ml Depotocin((R)) (0,4 mg Carbetocin) must be given 22 hours pos t PGF 2 alpha Cloprostenol((R)) in gilts and sows without parturition until this time (115.-116. day of pregnancy).
