[The synchronization of sow parturition using a combined treatment regimen of cloprostenol Jenapharm and depotocin Spofa].
The trials were conducted on a pig farm (German Landrace) over a period of about two years. This farm worked in 7-day cycles using artificial insemination. In trial 1, 209 sows were treated with the prostaglandin F2 alpha analog Cloprostenol (Cloprostenol Jenapharm, 87.5 micrograms i.m.). In trial 2, 646 sows were divided into two groups. Both groups were treated with 100 micrograms Cloprostenol Jenapharm not earlier than on the 113th day of gestation (day 1 of gestation = the day after the first insemination). 24 h later, 119 sows received an additional injection of 1 ml of an oxytocin analog (Depotocin inj. Spofa, 1 ml contains 0.2 mg Carbetocin). In the other group, 120 sows received 2 ml Depotocin. This additional treatment with Depotocin resulted in a mean interval from the injection to the onset of farrowing of 125 minutes (gilts) and 49 minutes (sows). In trial 2, 97.9% of the sows farrowed within 30 hours after Cloprostenol injection (= partus rate 30). The additional treatment with Depotocin resulted in a shortening of farrowing periods, a reduction in mean expulsion time and effected an increase in farrowing during the day time. All these effects were significant (p < or = 0.05).
