Signs of Intestinal parasites

The signs of worm infestation in horses can vary widely: some horses may show barely any signs; others will have severe disease and sometimes die as a result.

Signs of worms include:

  • loss of appetite1
  • poor growth2
  • weight loss2
  • anaemia, caused by redworms, which damage the blood vessels and the gut1
  • tail rubbing, due to irritation as pin worms crawl out to lay their eggs in the tail area1,2
  • coughing in young foals2
  • colic2
