Endoparasites of Pigs

Large roundworms (Ascaris suum) are the most common and economically important parasite found in pigs1. With over 70% of farms in the UK positive for Ascaris suum2, all types of pig farms are at significant risk.

Prevention and control of worms

  • Contaminated pens are the most common source of infection so adopting an ‘all-in all-out’ strategy is important for infection control.
  • Using a licensed broad spectrum anthelmintic effective against mature and immature stages of large roundworms, threadworms, red stomach worms, lung worms, whip worms and nodular worms will help reduce productivity losses.
  • For lungworm control, prevent access to earthworms.
