We used to want horses to be parasite free. In order to prevent resistant worms, the new goal is to maintain a low level of parasites.

Spring Recommendations:
Fecal: To know your horse’s parasite load If fecal egg count is low and the horse is healthy, do 2 fecals per year and deworm in the fall. If fecal count is high, deworm in spring and run another fecal 2-3 weeks after deworming to check effectiveness of dewormer.

Fall Recommendations:
All horses should be dewormed with an Ivermectin/praziquantal product after the first hard frost to kill bots and tapeworms along with other intestinal parasites. There are a few horses who will need to be dewormed every 8 weeks but this is the minority.

Foals under 1 year of age should be dewormed every 4-8 weeks with a rotational dewormer. After 1 year of age, the adult strategic deworming protocol should be adopted.

We will be happy to discuss your horse’s specific needs.
