Phylogenetic Analysis of Porcine Circovirus 3 Circulating in Canadian Pigs

Abstract: Phylogenetic analysis of porcine circovirus 3 circulating in Canadian pigs

Introduction: Porcine circovirus 3 (PCV3) has been detected in pigs worldwide and associated with several clinical signs.
Methods: To investigate the genetic diversity of PCV3 strains circulating in Canada, 44 PCV3 positive samples from Saskatchewan (2/44), Manitoba (2/44), Quebec (4/44), Alberta (11/44) and Ontario (25/44) submitted to diagnostic laboratories in Canada between 2019 and 2021 were sequenced and analyzed.
Results: Phylogenetic analysis of capsid genes showed that all of the 44 Canadian strains classified into PCV3a and segregated into seven lineages with common amino acid changes observed at A24V, R27K, N56D, T77S, Q98R, L150I (F) and R168K positions.

Video: Exploring Precision Data in Swine Production - Dr. Janice Siegford


In this episode of The Swine it Podcast Show, Dr. Janice Siegford from Michigan State University discusses how precision livestock farming data can support pig health, welfare, transparency, and decision making. She explains why data ownership, privacy, consumer perception, and cost sharing must be addressed as technology becomes more common on farms. Listen now on all major platforms.

“Precision livestock farming data can support producers, veterinarians, certifiers, and consumers by enabling improved monitoring, prediction, and decision-making across the entire production system.”

Meet the guest: Dr. Janice Siegford / janice-siegford-24318839 is a Professor and Associate Chair in the Department of Animal Science at Michigan State University. Her expertise in animal welfare, neuroscience, and zoology supports research on pig behavior, stress resilience, and precision livestock farming. Her work explores early weaning, genetics, and stakeholder perspectives on technology adoption to improve pig care, health, and productivity.
