Controlling Parasites in Sheep and Goats
When it comes to wormers there are a lot of choices. Ivermectin drench and injectable, Cydectin drench, Valbazen, Safe-guard, Dectomax, levamisole and a feed product, Goat Dewormer Concentrate containing Morantel Tartrate. They are all effective in the right situation. Basically, it boils down to:
- White wormers such as Valbazen and Safe-guard.
- Ivermectins such as Cydectin, Ivomec, Dectomax and levamisole, which is marketed as Prohibit or LevaMed.
- The outliers are goat dewormer and Livamol® with BioWorma®.
So which should you choose?
There is little benefit to using a white dewormer unless you are in an area with liver flukes. If so, we recommend Valbazen. When using white wormers the dosage can be increased without a problem.
As for the ivermectins, we prefer Dectomax. An added benefit is that it’s effective against heel mites. Dosage is 1cc per 110 lbs. Overdosing ivermectin products isn’t necessary, but even so it’s not usually a problem.

Tapeworms are the only worms that can be seen without the aid of a microscope. Tapeworms are nonpathogenic, so we generally ignore them. You can get rid of tapeworms, but they will return until the animal develops an immunity. There is no economic significance to treating for them.
Goat Dewormer Concentrate is an interesting alternative to drenching or injection and is very effective. But how do you feed it accurately to each animal?
Livamol® with BioWorma® has been used successfully to eliminate larvae from the pasture in Europe and Australia, but is new to the USA. It does not eliminate parasites present in the animal. Animals need to be treated with a dewormer/anthelmintic to first to rid the animals of worms.
