Haemonchus contortus is a primary concern for goat producers. An infestation of H. contortus, known as haemonchosis, can cause poor development, poor performance, and death. Due to the development of anthelmintic resistance, alternative ways to monitor and control haemonchus have been researched. Alternatives treatments to chemical anthelmintics are copper oxide wire particles (COWP) and copper sulfate (CuSO4). These have been found to be effective at controlling H. contortus populations in goats with a lessened resistance development, and are beginning to be used alongside chemical anthelmintics to combat resistance development in H. contortus. This study was performed to compare the effectiveness of COWP vs CuSO4 vs Levamisole.
