Administering a dewormer does not guarantee that animal has been dewormed, therefore it is important to periodically check and see if the drug you are using is working in your horse. Faultless Fecal Egg Counts does this by conducting two separate FECs. The first sample (pre test) is analyzed prior to administering dewormer and the second sample (post test) is analyzed  after dewormer is given. The results are then calculated, a fecal egg count reduction of less than 90-95% indicates a resistance. It is recommended this test is conducted every spring prior to an annual visit from the veterinarian.

You will receive;

  1. Your horses shedding rate (low, medium, high) and the eggs per grams of feces for each sample (pre/post)

  2. A personalized yearly deworming plan for each sample (pre/post)

  3. A list of dewormers and the recommended wait time between the pre and post test (7-14 days)

  4. Your horses fecal egg reduction rate and suggestions to improve any dewormer resistance


If you can only afford one fecal egg count per year, run it right before deworming your horse for the first time in the spring. If the number is low (less than 200 eggs per gram), that particular horse has good natural immunity to strongyles and may not need dewormed as frequently. However, if the number is more than 200 eggs per gram, that horse may be a “high shedder.” This is a horse who may not show signs of parasitism, but is carrying lots of adult worms that are laying lots of eggs, spreading them all over your pasture to the other horses. High shedders need dewormed more often than other horses. It is recommended that FEC be conducted every spring and fall.
