Abstract
Detection and Investigation of Atypical Porcine Pestivirus within a Breed-to-Finish Farm and Off-Site Nursery and Finisher Locations
Highlights
Atypical porcine pestivirus (APPV) is part of the Flaviviridae family and has recently been associated with clinical signs of congenital tremor (CT) and splay leg (SL) in piglets during the lactation phase
A commercial farrow-to-finish farm with replacement gilts coming from an off-site genetic multiplier farm, and semen delivery from a commercial boar stud began to see an increase of congenital tremors (CT) and SL in the farrowing room in early 2020
The objectives of this investigation were to determine the prevalence of clinical APPV cases at the farrow-to-finish farm, understand the route of introduction of APPV into the farrowto-finish farm, and understand the prevalence of APPV viremia within a population of offspring from a gilt multiplication farm through an off-site nursery and finisher barn
Summary
Atypical porcine pestivirus (APPV) is part of the Flaviviridae family and has recently been associated with clinical signs of congenital tremor (CT) and splay leg (SL) in piglets during the lactation phase. Clinical signs occur in piglets exposed to the virus during gestation when the dam is viremic for APPV prior to day 70 of gestation.[4] The major cost associated with APPV is pre-weaning mortality due to inability to nurse or move about the farrowing stall.[5] These clinical signs are usually most prominent during lactation, while clinical signs become less common after weaning. This study’s objective was to determine the prevalence of clinical cases of APPV in a naïve farrow to finish swine farm, understand the route of introduction, and assess the prevalence of APPV within a population of nursery and finishing pigs
