    Hi Casie,

    I recently read about someone and their herd of horses and the DE worked for them as for as getting rid of parasites, Food Grade quality of corse.

    So I did a fecal exam for both my horses and they tested positive for Strongless egg counts, one has 1000 and the other 500. It’s been a week and I plan to retest the fecal again within 6 weeks to see results, I really hope this helps.

    Chemical deworming, although works if you do it right, but I also read why deworm a horse if they don’t have worms. So, I never followed what the general public do which is deworm a horse every 3 months or so, that’s barbaric. So when my horses fecal egg count gets to about 1000, that’s when I do a chemical deworm, but this time I’m trying the DE to see if that helps. I would only chemically deworm them twice a year, one in winter and one end of Spring.

    My Mare who is only 5 years old is much healthier then my Gelding who is 13 years old. I have been feeding my Mare since she was 1.5 years old with Garlic and she never contracted worms, was always the eggs, and it’s taken her 6 month to reach only at 500 egg count. My Gelding is doing allot better as this year will be two years that I have had him. His egg counts are becoming less each year with me feeding him Garlic on a daily basis.

    How much are you feeding per horse per day ?

    • Casie says:

      I feed approximately 1/2 cup a day per horse, but you can feed more. I remember Joe Camp saying he fed a cup or possibly more to certain horses with higher FEC’s.

      • Rebekah says:

        I’m feeding both my horses 1 cup a day and will do this for 4-6 weeks, then will do a fecal count, and if eggs are less than 200 counts, than I will continue but only giving them half cup a day until all egg counts are next to none. For maintenance I will be feeding them 1 cups a week or maybe 2 cups a week.

  3. Is it harmful for the horse’s resporatory system if breathed in?

  4. Holly McKay says:

    I feed DE to my mare, and I feel like it has made a difference to her joint health and overall condition. I wet her feed and mix the DE in with my hand to prevent any DE from getting in her lungs.

  5. Rebekah says:

    Anything with a powder consistency I always add some water but not to much my Mare don’t like mush, as I am feeding them Garlic which is a powder consistency.

    Hi Cassie,

    Hi, Casie! I have been feeding my 28 yr old mare, Cassie, DE as a dewormer for the last 5+ years and I can attest that it works! I have her fecal tested every 3-4 months and since using the DE she has NEVER tested positive for worms! I am a staunch proponent of natural products for my horse. I have had her for 6+ yrs, she was my first….a senior horse for a senior me!! We are proud to be metal free (no shoes, no bits) & her only health problems were caused by tick bites (Lyme Disease & Anaplasmosis). But she survived both & I strongly believe it’s because her immune system is strong due to natural care. Thank you for your site, I just discovered it & will be visiting it regularly!

    We have fed our horses DE for about 4-5 years now. It works. We haven’t used any chemical dewormers since starting DE. We just add it to their grain/supplements rations almost daily.

    • Casie says:

      That’s great to hear. Thanks for sharing!

    • brittany says:

      how much do you feed daily?

      • Casie says:

        It depends on the size of the horse and the reason for feeding (feed more for higher worm counts), but I feed around 1/4 to 1/2 cup to my 1000 lb. horses.

          Hi I hope this conversation is still ongoing. I have been researching products to help my horse with sweet itch and amongst the ingredients on a couple of these products was DE. Has anyone used it specifically for sweet itch or has it just been used for worming?
