    Can you deworm sheep with horse ivermectin paste. If so what dosage.

    You can always contact the maker of the wormer and ask them. There is usually contact information somewhere in the packaging or on the label.
  3. A LOT of anthelmintics & medications used in goats & sheep are used "off label". Many times the manufacturer cannot recommend a dosage because the medication is not approved for that species.

    You can try to call a local large animal vet, but many times, those vets do not have a lot of experience with goats & sheep, especially with dewormers and antibiotics.

    If you are on Facebook, there is a group called Goat Vet Corner that is an AMAZING resource for questions like what dewormer is safe and what dosage. It is run by a long list of vets from around the world, so you are getting educated veterinarian advice vs. a layman's advice. Not saying that all advice from goat and sheep owners is wrong, but a lot of it is...

    Ivermectin DOES make a sheep drench, so ivermectin IS safe for sheep. But!!! The dosage of the drench is likely NOT the same for equine ivermectin paste. You have to pay attention to the concentration of ivermectin in the product!

    You can, and I think the dose is 0.2 mg/kg, and with 1.87% ivermectin paste that works out to ~0.05 cc (ml) per 10 pounds.

    10 / 2.2 x 0.2 /18.7 = ~0.05 cc (ml)

    Very good point! One must always double check the number of mg per ml or mg per gram. I think the sheep drench product is only 0.8 mg/ml, the injectable is 10 mg/ml, the pour on is 5 mg/ml, and the horse paste sold in the US is 18.7 mg/g.

    FYI, one ml (cc) of the paste weighs one gram.
