Hi Everyone,

I have been on these boards for years, but mostly as a lurker! I sometimes have something to contribute to the dairy goat forum, as that is my area of expertise ;~)

We now have 2, 6 month old Lincoln Longwool ewes that I want to de-worm. I always use a little bit of the horse wormer for my goats. Can I do this for sheep? Does anyone have a dosage for using horse Ivermectin in sheep?

Thanks,
Chris

Equine Ivomec paste is 1.87% ivermectin, while the Ivomec Sheep Drench is .08% ivermectin. Ivomet Sheep Drench has a recommended dose of 3 ml to 26 pounds, therefore 12 ml for a 100# sheep would have a concentration of 0.0096ml of ivermectin. If I calculate the concentration in the 1.87% that would equate to 0.5 ml?

That would be about 1/2 the equine dosage....somewhere I thought I read it was to be doubled?

I'm sorry I'm still trying to wrap my mind around this. For simplicity. I have a 100lb sheep that needs to be wormed. I have the 1.87 apple Ivermectin with lb. notches on the plunger, goes up to 1250lb for a horse. So for a sheep give how much? Hope I didn't give to much.:oops:

For those who used the horse paste, how do you measure it? Mine has notches of 250# increments so I put it into a syringe-250# =1.5 ml. I ended up dosing .5 ml per sheep (or trying to anyhow). It didn't seem a very effective way of measuring as I'd have 1.5 ml in a syringe and then need to put .5 ml in the mouth -some got more some got less.

sheep stupid goat smart person here, us goat folks always take and squirt the meds out and mix them up better then pull them up in a syringe so that a more accurate dose can be given.

I used to (and my dairy goat friend still does) the ivomec paste and dose by weight. I had big suffolk girls so I would just divide the 250 squirts into two. I figured the little bit extra would compensate for the bit they always managed to spit out. Worked very well for us. If I had smaller sheep I would use cannon farms method but I would cut the tip off of a catheter needle so you're not trying to squeeze that thick paste through a needle hole.
