本研究的目的是调查伯克希尔母猪在PED爆发后断奶时的卵巢状况和随后的繁殖性能。本研究在一个从2014年1月6日开始发生PED爆发的从产仔到出栏的农场进行。从2013年7月至2014年7月，每月从19至20头母猪断奶时采集血液样品，以调查卵巢状况。2014年1月的平均孕酮浓度在数值上高于其他月份，但这种差异并不显著。2014年1月的平均雌二醇-17 β浓度高于2013年7月和10月（P < 0.05）。此外，在PED爆发之前（2013年）和之后（2014年）的1月，2月和3月期间比较了生殖性能。1月份分娩的母猪2014年的断奶前死亡率高于2013年（P < 0.05），但2月和3月分娩的母猪2013年和2014年的断奶前死亡率相似（P > 0.10）。2014年1月至3月分娩的母猪的分娩率比2013年同期分娩的母猪低15%（P < 0.05）。总之，我们的研究结果表明，与爆发前相比，PED爆发后伯克希尔母猪的繁殖性能较差。
The purpose of this study was to investigate the ovarian condition at weaning and subsequent reproductive performance of Berkshire sows following an outbreak of PED. This study was conducted on a farrow-to-finish farm that experienced a PED outbreak beginning on January 6, 2014. Blood samples were collected at weaning from 19 to 20 sows every month from July 2013 until July 2014 to investigate the ovarian condition. The mean progesterone concentration was numerically higher during January 2014 than the other months, but this difference was not significant. The mean estradiol-17β concentration was higher during January 2014 than during July and October 2013 (P < 0.05). In addition, reproductive performance was compared during January, February, and March before (2013) and after (2014) the PED outbreak. Sows that farrowed in January had higher preweaning mortality in 2014 than in 2013 (P < 0.05), but sows that farrowed in February and March had similar preweaning mortality in 2013 and 2014 (P > 0.10). Sows that farrowed between January and March 2014 had 15% lower farrowing rate than those that farrowed during the same months in 2013 (P < 0.05). In conclusion, our results demonstrate poorer reproductive performance of Berkshire sows after a PED outbreak compared with before the outbreak.
