Drug Resistant “Super Worms” Pose New Threat to Horses

Intestinal parasites can wreak havoc with horses of all ages, causing weight loss and damaging not only the gut, but other organs. Typically, the best ways to keep worms at bay include rotating pastures and keeping pastures harrowed regularly. It was also long believed that regular bi-monthly deworming of horses was the best way to keep the animals parasite issues managed, but science now suggests that is not the case.

In fact, studies show that 20% of the horses in a paddock will carry 80% of the parasites. Therefore uniform deworming protocols is not only unnecessary, but can create resistance in parasites, or super worms.

Taking a fecal egg count in horses twice a year (spring and autumn) to determine if and what type of de-worming protocol they need is the recommended approach to parasites.
