I thought that roundworm and tapeworm were the same thing, but I learned today that they aren't.
This convinces me that Wazine 17 (kills only roundworms) should be given before any other worm medicine, i.e., clear the roundworms out first so the chicken's system won't be overloaded with dead worms to dispose of; then wait ten days before giving Valbazen.
ROUNDWORMS (Nematodes) include the families of HOOKWORMS, PINWORMS, WHIPWORMS, THREADWORMS, etc. These can range in size from as small as 1 mm. to as large as several inches/mms. They are most commonly found in the intestines of the host. They are often contracted through the skin. By migrating throughout the body, they can cause a wide variety of symptoms of disease.
TAPEWORMS (Cestodes) are generally the largest of all of the parasites. They are very mobile, and can change location within the host daily. They are segmented worms. They have 3,000 to 4,000 segments in their bodies. Each segment can contain up to 50,000 eggs! They are able to release up to 1,000,000 eggs into the host's body EVERY DAY! Some tapeworms can live up to 25 years within a host. They have been known to grow as large as 33 feet in length (10 meters) within the gastrointestinal tract. However, their larvae can be found in almost any organ.
