猪流行性腹泻（PED）是一种在许多国家出现的猪的新疾病。在本研究中，比较了在生产的不同阶段暴露于PED病毒的伯克希尔母猪的个体母猪生产力。在日本鹿儿岛县的一个商业化产仔至终末农场中，2014年1月6日在分娩畜棚中观察到PED的临床存在，1月9日对所有后备母猪和经产母猪进行免疫接种，分娩畜棚中的后备母猪和经产母猪除外。根据暴露于PED病毒的时间将母猪分为6组：0-30天（G1）、31-60天（G2）、61-90天（G3）或妊娠91天后（G4）、哺乳期（L）和断奶后（W）。对照组在PED爆发期间未暴露于PED。该研究基于574份生产记录。G4组和L组母猪的断奶仔猪最少（分别为4.8 ± 0.4头和4.0 ± 0.3头; P < 0.05），断奶前死亡率最高（分别为33.1 ± 4.8%和39.7 ± 4.1%; P < 0.05）。然而，G1、G2、G3和未感染组的断奶仔猪数量和断奶前死亡率没有差异。G4组和W组的产仔率略低于未感染组（P < 0.05），但随后的仔猪产仔性能与未感染组相似。总之，PED对个体母猪生产力的影响因母猪暴露于PED病毒的生产阶段而异。
Porcine epidemic diarrhea (PED) is an emerging disease of pigs in several countries. In the present study, individual sow productivity of Berkshire sows exposed to PED virus at different stages of production was compared. On a commercial farrow-to-finish farm in Kagoshima Prefecture, Japan, the clinical presence of PED was observed in the farrowing barn on January 6, 2014, and all gilts and sows were immunized on January 9, except those in the farrowing barn. The sows were categorized into six groups based on the period in which they were exposed to PED virus: between days 0–30 (G1), 31–60 (G2), 61–90 (G3), or after 91 days of pregnancy (G4), during lactation (L), and after weaning (W). The control group was not exposed to PED during the period of PED outbreak. The study was based on 574 production records. The sows of the G4 and L groups had the fewest piglets weaned (4.8 ± 0.4, and 4.0 ± 0.3 pigs, respectively; P < 0.05) and the greatest pre-weaning mortality (33.1 ± 4.8%, and 39.7 ± 4.1%, respectively; P < 0.05). The number of piglets weaned and pre-weaning mortality, however, did not differ among the G1, G2, G3, and uninfected groups. The G4 and W groups had slightly lesser farrowing rates than the uninfected group (P < 0.05), however, similar subsequent piglet litter performance as the uninfected group. In conclusion, the effect of PED on individual sow productivity differed with the production stage in which sows were exposed to PED virus.
