Hookworms in pigs

Hookworms are a minor player in pigs compared with the large roundworm — but they're part of the parasite picture, especially in pasture-raised herds.

The species involved

The swine hookworm is Globocephalus urosubulatus, found in the small intestine. In most herds the dominant intestinal worm is the large roundworm Ascaris suum, with hookworms more likely where pigs have outdoor soil access.

How pigs get infected

  • Swallowing or skin-penetration of larvae from soil
  • More common in outdoor or deep-litter systems
  • Favoured by warm, moist ground

Signs to watch for

Poor growth, rough coat, anemia and diarrhea in heavier infections. Often subclinical, showing up mainly as reduced thrift and feed efficiency.

Treatment & control

Fenbendazole and other broad-spectrum dewormers control hookworms along with the more significant roundworms. Combine treatment with clean, dry housing and good manure management.

Confirm with your vet. Species, age and weight all change the right product and dose. Use this guide to understand the problem, then let your veterinarian tailor the plan.
