Our small herd of Nigerian Dwarfs in hot an humid climate is becoming increasingly resistant to dewormers commonly used in goats. We use FAMACHA, and fecals to determine worm load and species so we can target only the animals with high load. We also try to cut browse from Brazilian Pepper trees and pine, which are said to have anthelminthic properties. I am wondering if there are tinctures fit to use in goats, specifically against Barberpole worm?
