The effects of vaccination of a porcine parvovirus (PPV) in gilts and the first four litters were studied in a pig-breeding herd. In addition to determination of the technical results, PPV and influenza (H1N1) titres were measured. From the serological findings it was apparent that PPV and influenza (H1N1) virus circulated during the trial. The number of total-born and live-born piglets was significantly higher in the first litter when PPV-vaccinated and non-vaccinated gilts were compared. On the basis of these results, it is recommended to vaccinate sows and gilts after the first litter.
在一个养猪场中研究了后备母猪接种猪细小病毒（PPV）及其头四胎的效果。除了确定技术结果外，还检测了PPV和甲型流感（H1N1）抗体滴度。从血清学结果来看，在试验期间PPV和甲型流感（H1N1）病毒都在传播。比较接种PPV和未接种PPV的后备母猪时，头胎的总产仔数和活产仔数显著更高。基于这些结果，建议在母猪和后备母猪第一胎产仔后进行疫苗接种。
