伪狂犬病病毒（PRV）在日本的一些地区流行。我们调查了PRV感染状况对猪群生产力的影响。从日本的48个猪群中获得血清样品。在每个猪群中，从四个不同年龄的生长猪以及低产次和高产次组的母猪中获得三份血清样品。通过竞争性ELISA测试血清中针对野生型PRY的抗体。根据血清学结果将猪群分为PRV阳性组和阴性组。感染PRY的猪群断奶后死亡率（6.84%）显著高于未感染猪群（4.73%）（P=0.0018）。由于PRY阳性畜群的生产力降低，必须加强目前的PRY根除计划。
Pseudorabies virus (PRV) is endemic in some regions of Japan. We investigated the effects of PRV infection status on herd productivity. Serum samples were obtained from 48 swine herds in Japan. Within each herd, three serum samples were obtained from growing pigs at four different ages, as well as from sows in low and high parity groups. Sera were tested for antibodies against wild-type PRY via competitive ELISA. Herds were classified into PRV positive and negative groups based on serological results. Herds infected with PRY exhibited postweaning mortalities (6.84%) that were significantly (P=0.0018) higher than those in unaffected herds (4.73%). Because of the reduced productivity in PRY positive herds, the current PRY eradication program must be strengthened.
