Stomach Worms

Stomach worms that affect goats all have similar life cycles and are treated in a similar way. Routine worming with annual alternation between clear and cloudy anthelminthics should control stomach worms. One of particular concern is Haemonchus contortus because its life cycle includes a dormant larval form that resides in the host months after effective worming has taken place to eliminate mature worms in the gut. It is not possible to detect the larval forms with common laboratory techniques. As the larvae get ready to mature, they migrate through the tissue into the sinus cavities and are swallowed, ready to take up residence in the stomach. Some larvae may get lost however and end up in the brain, causing neurological symptoms that are not treatable.
