母猪同期分娩存在的问题及对策

Problems and Strategies for Synchronous Parturition in Sows

同期分娩是实现生猪批次化生产的关键技术之一,实施同期分娩可使母猪在预定时间内集中产仔,不仅可对仔猪和母猪进行集中护理,还可及时对仔猪进行寄养,降低仔猪死亡率,同时提高工作效率。但诱导母猪同期分娩存在一定风险,包括过早使用前列腺素可能会降低仔猪活力,使用缩宫素可能增加母猪难产等。因此,本文将实施同期分娩对仔猪和母猪的影响及过程中存在的问题进行探讨,以期规范同期分娩技术操作,为进一步推进集约化生产管理提供理论依据。

Synchronous parturition is a key technology for sow batch farrowing production practices. Synchronous parturition is practically beneficial for increasing the synchronous farrowing, intensive farrowing supervision for newborn and postpartum sows, fosterage of newborn piglets, thereby reducing the neonatal mortality, and improving employee efficiency. However, there remain some risk factors associated with the synchronous parturition, e.g., decreased piglet viability when prostaglandins are administrated too early, as well as increased dystocia due to the use of oxytocin. In this review, by focusing on the problems in the procedures of synchronous parturition and the adverse effect on piglets and sows, we provide a reference for standardizing the technical operation of synchronous parturition and thus promoting the intensive farrowing management.
