Fall & Winter 2017 Deworming Protocol

What is the latest in parasite research? How do we apply it? 

Research shows that parasites are becoming resistant to our deworming agents, but many horses, about 60 – 70% in Colorado, have a good immune system, thus only need to be dewormed two times per year. Because each horse is different, we recommend having a fecal test done on your horse.

Fecal tests accomplish many good things: 

  • Determines if your horse has parasites in his intestines. Parasites cause colic, weight loss, anemia, and poor hair coats.
  • Indicates how often to deworm to keep your horse healthy.
  • Decreases resistance of the parasite to the present deworming medications on the market.
  • Reduces costs by not over-deworming. 

Fecal tests needs to be done when the weather is 40° or warmer throughout the day and night, and after two months or more from the last deworming. 

This Fall, we recommend deworming at the end of November or early December using a medication which will kill bots in the stomach and tapeworms in the large intestine. These medications are respectively: moxidectin or ivermectin + praziquantel. Quest Plus combines both, as does Equimax. You can purchase these medications through Colorado Equine Clinic or a store like Murdoch’s. 

In conclusion, we suggest the following:

  • All horses have a fecal test in accordance with the guidelines above
  • If fecal test is negative, deworm in late November/early December
  • If fecal test shows a high egg count, deworm now (in September/October) and again in late November/early December
