What dewormer is best for horses2007-11-24 21:21:25

I just bought my first horse, a 2 year old American Warmblood gelding, and I was wondering what dewormer would be best for him. He's had no prior colic problems and is in a somewhere around 20 acer pasture with 10 or so other geldings in southwest virginia.

Answers:

I just wanted to point out that rotating deworms, is yes the best way to go, but you need to switch classes of dewormers not just brands.

Ivermectin and Zimectrin are the same product. (1.89% Ivermectin paste). You want to rotate with Fenbendazoles, Ivermectins, moxidectin/ praziquantel ,pyrantel pamoate etc.

You should use a rotation so that immunity isn't built up. I use Ivermiectin, Strongid, and Panacure.

Rotating your wormers is best..Using the same one all the time causes the horse to become immune to them...Anything with ivermetin works well...Have your horse on a good worming schedule...Every 6-8 weeks is sufficiant.

You should have your horse on a rotation schedule. Some feed stores have a chart so you can put it up in your tack room as a reminder of when to get various wormers. There is no wormer (that I have found) that is better than the others. Just recently we tried a wormer that you poured on the feed. It was a lot easier than the tube, and the horses didn't mind it.

Back to the point though. If you are tight with money, then go for the generic named products with the same ingredients...they work just as well. If you have the money to spend, Ivermectin, Panicure, etc. are great to buy. One thing I would recomend is getting the Panicure Power Pack for your horse if he hasn't been wrmed in a while. This is about a week of worming tubes that will flush out anything that might be in your horse's system. My trainer uses it on all her horses once a year, but I just used it on a horse I didn't know the worming history of. Hope this helps!

What to use and when to use it might vary in your part of the country. For instance, I know in the south we have to deworm more often than up north (due to the fact that we have milder winters). The best thing to do is to ask either your vet or whoever you keep your horse with what schedule they use. It is always best to rotate dewormers as this will keep the parasites from building up immunity. I am sure if you call your vet and ask them the recommended deworming schedule for your area, they would be more than willing to give it to you.

We usually don't stick with just one dewormer, on the off chance that the nasties can become immune to it. Every few wormings we switch brands. Hope this helped a little.

Rotating wormers is the best thing. I tend to use Ivermectin in the winter, switching to Zimmetrin in the spring and summer (something that will take care of certain tape worms and bots) and then switching back to the Ivermectin in the fall.

Rotating your wormers keeps him less-immune to one type of solution, so I would rotate wormers every three or four wormings. Ivermectin, I must personally say, is a great option. There's more about wormer at http://www.horse.com/default.aspx...
