    Jeffers makes a great quality product. The de-wormers are top quality along with the other products and items they make! As goes with any medicine or health product - follow your vets instructions and use common sense.

    Works just as well as more expensive brands. Please check stool samples Before using any deworming products. Two of my seven didn't need anything! Rotate products!

    "Great Quality at a Great Price"

    I use this brand in lieu of the pricier brands that contain the exact same ingredients. The results are just as good as the big name brands.

    "Super farm worker!"

    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.

    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!
