Although Influenza A virus diversity has been well documented, there is limited information on how farm management practices influence the diversity of IAV. A study presented at the 2025 Leman Swine Conference evaluated the association between herd-level management practices and the genetic diversity of IAV in weaning piglets.
This study provides field-based evidence that herd-level management practices can influence the genetic diversity of IAV in pig populations. Practices such as vaccination, gilt management and co-infection with other diseases appear to shape the evolutionary landscape of IAV by modulating opportunities for co-infection and reassortment.

Integrating IAV surveillance with specific management practices may be essential to design effective IAV control strategies in pigs.”
