Abstract: The effects of using different management methods on the farrowing performance of parturient sows were studied. 160 sows of 4 pig houses in a ecological farm were divided into 8 groups to make comparative test. Group 1, 2, 5 and 6 were used as experimental groups and group 3, 4, 7 and 8 were used as control groups. Based on the normal feeding and management, sows in group 1 and 2 were driven into the delivery room a week in advance and sows were injected with 0.1 mg cloprostenol per sow by intramuscular injection. The sows in group 3 and 4 were driven into the delivery room a week in advance, but cloprostenol was administrated. The sows in group 5 and 6 were driven into the delivery room after lactating and sows were injected with O. 1 mg cloprostenol per sow by intramuscular injection. The sows in group 7 and 8 were driven into the delivery room after lactating and sows weren＇t injected with cloprostenol. The results showed that the live litter size of sows with prenatal administration of cloprostenol was significantly higher than that without prenatal administration of cloprostenol （P〈O.05）, the proportion of stillbirth and mummy was significantly decreased （P〈O.O5）and the farrowing time was obviously concentrated. The live litter size of sows that were driven into the delivery room after lactating was significantly increased than that a week in advance （P〈O.05） and the proportion of stillbirth and mummy was significantly decreased （P〈O.05）. The average live litter size of sows that were injected with cloprostenol and driven into the delivery room after lactating could be increased and the proportion of stillbirth was decreased. The farrowing performance of sows in group 5 and 6 was the best, followed by group 7 and 8.
