Barber pole worm (Haemonchus contortus) is the most serious parasite problem on pasture-based Northeast goat and sheep farms. Copper oxide wire particles (COWP) have effectively reduced infection of barber pole worm in studies in the Southeast US, but it is not clear how safe and effective they are in the Northeast. Therefore, Cornell University has embarked on a three-year study to look at methods for incorporating COWP into Northeast parasite control programs.
Copper oxide wire particles were developed to treat copper deficiencies in livestock in regions where copper is not readily available in soil and forages. Because of this important role, they are already approved for organic farming and may prove to be an important new tool for both organic and conventional farms. They are administered to livestock in the form of gel capsules with a dosing syringe (Figure 1). Continue reading
