Abstract
Levels of colostrum-derived antibodies in piglets born to sows naturally infected with Aujeszhy's disease virus were determined, and isolation of the virus from the unweaned piglets with the antibodies was carried out. The antibodies were diminished at constant rates approximatelly similar among different litters and reached negative levels at 45- to 60-day-old. The viruses were isolated from kidneys and brains of the neonatal piglets at 2-day-old. These results indicate that piglets with colostrum-derived antibodies undergo subclinical Aujeszky's disease virus infection.Keywords
