How do you treat haemonchosis in cattle?
Treatment against H. contortus using chemical and natural anthelmintics and dewormers is one approach to managing haemonchosis. Another common practice is selective treatment. Some organizations are educating farmers to use the FAMACHA method to identify and treat only those with high haemonchosis levels using their eye color.
