    Jeffers Ivermectin horse wormer has been a staple at our farm for years - for goats, donkeys, and occasionally dogs. Never lets us down.

    "Great price!"

    I bought this when it was on sale. Great product at a great price. Did have a strong apple odor that the horses seem to appreciate.

  4. 3.0 out of 5 stars


    I have used this product for many years and loved it's affordability. However, I have NOT rotated dewormers often enough and didn't realize this until very recently. ALL of my horses are infested with roundworms and I am SHOCKED! I will not be using ivermectin for a while... I will be rotating between Quest Plus and Exodus or Safeguard until I get my pastures cleaned up. Lost a super nice filly to the roundworms this week.... what an expensive lesson to learn! ROTATE YOUR DEWORMERS OFTEN! I never thought we'd develop a resistance to ivermectin but we did!

    "Effective Dewormer"

    We have used Jeffers Ivermectin for years. The price is right and it works. Our vet does fecal counts for us and there is never a problem if we have used the product on schedule.
