Effects of different induction protocols on the synchronization of daytime farrowing in sows
摘要
Abstract
This experiment was conducted to investigate the effects of different induced parturition synchronization protocols on daytime farrowing in sows.A total of 984 Landrace×Yorkshire crossbred sows were selected and divided into three groups according to practical farrowing-intervention protocols applied on the farm.Sows in the cloprostenol group were intramuscularly injected with 0.2 mL per head of DL-cloprostenol sodium at 08:00 one day before the expected farrowing date.Sows in the carbetocin group received an intramuscular injection of 1 mL per head of carbetocin at 08:00 on the expected farrowing date.For the combined cloprostenol-carbetocin group,sows were intramuscularly injected with 0.2 mL per head of DL-cloprostenol sodium in the neck at 08:00 one day before the expected farrowing date;24 h later,1 mL per head of carbetocin was injected behind the ear at 08:00 on the expected farrowing date.The daytime farrowing rate and litter performance of sows were determined.The results showed that the daytime farrowing rate in the combined group was significantly higher than that in the cloprostenol group and carbetocin group(96.24%vs.86.84%vs.86.67%,P<0.05),and the farrowing duration in the combined group was extremely significantly shorter than that in the cloprostenol group(P<0.01).In primiparous sows,the daytime farrowing rate of the combined group was significantly higher than that of the cloprostenol group(100.00%vs.87.64%,P<0.05).For multiparous sows,the combined treatment significantly shortened farrowing duration(P<0.01)and increased the number of live-born piglets per litter(P<0.05).In conclusion,combined administration of DL-cloprostenol sodium and carbetocin could effectively increase the proportion of concentrated daytime farrowing,which helps improve piglet uniformity during batch production on large-scale pig farms.关键词
