Quote: I mean this in the nicest way possible...
I did a quick search and could not find any information on the efficacy of oak leaves for treating parasites in livestock. What I'm afraid of is that @chicken hawk 33 will take what you said and believe it works... heck people already think this about pumpkin seeds, garlic, ACV, etc. Of course what CH should do is have routine fecals done, but I doubt that will happen, so it might be best for him to invest in the best wormer he can afford.
Chicken hawk 33, call some livestock vets and ask them for information on what people in your area are using to de-worm with. Also call some well known goat breeders and ask them. Goats get *tons* of worms, and some of those are resistant to certain wormers. You might want to go to a vets office and ask if they have a copy of the "Veterinary Parasitology Reference Manual" that you could look at. In it is very detailed information on the types of goat worms and the medications used to treat them.

It would be a great help to rotate pastures as much as possible, too, to lessen re-infestation.
