Top Ten Worming and Wormer Misinformations - Graphic Pictures!

[casportpony]

So many to list, but I'll start with:

• 3cc Safeguard per gallon. This is a huge pet peeve of mine! Who started this and why do so many people still think it's an effective way to worm? This is a chick that had been treated with 3cc Safeguard per gallon.

• Wazine is a good wormer. Nope, it only gets roundworms.
• DE, ACV, pumkin seeds prevent/treat worms. Nope, they don't dont.
• Ivermectin is a good wormer for poultry. Nope, many studies show otherwise.
• My bird doesn't have worms because I don't see them in it's poop.

Good information!

If I may add another misconception, here's one that seems to be pretty common:

• Diatamaceous Earth works as a dewormer. Not true! Diatamaceous Earth, though sometimes effective against external parasites, is pretty useless when wet, such as when it travels through a chicken's digestive tract. It will not treat your birds if they have worms, and may not work well as a preventative, either.

Yes, lol, that should definitely be on the list!

Common belief: Ivermectin is an effective dewormer, especially nematodes (roundworms).

The truth is: * The pharyngeal muscle of avr-15 mutants does not respond to ivermectin (Dent, Davis and Avery, 1997; Pemberton et al., 2001) clearly indicating an involvement of GluClα2. An important point to note in terms of the site of anthelmintic action of ivermectin is that although the pharynxes of avr-15 mutants are not inhibited by ivermectin, populations of avr-15 mutants exposed to ivermectin are still paralyzed.

This will also be on the list!

Following this thread. Is there a thread listing correct info on what to give and dosages for different ailments?

With all the varying percentages of ingredients in medications among different manufacturers, the different medications targeting the same disease, that could be a long intensive list. Some medications are more effective than others, some are safer than others, some are for broad spectrum use, and others meant to target specific diseases most effectively. Contacting the manufacturer of the medication is always the best first step since there is so much misinformation on the web, even among sellers of certain products..

Quote: So true, but if one is looking for a good starting point I think poultry pedia has the best list available. It's not perfect, but it's much better than most.

With the Benzamidazole class of dewormers, it is clear that their anthelmintic effectiveness upon Helminths (intestinal worms) is due to their ability to compromise the cytoskeleton through a selective interaction with the Helminth.
http://www.wormbook.org/chapters/www_anthelminticdrugs/anthelminticdrugs.html

This is important to know since anthelmintics such as Piperazine (Wazine) and Levamisole cause paralysis in intestinal worms rather than destruction of the worm itself. A high number of worms paralyzed in the intestinal tract of a chicken could cause impaction if the intestinal tract is irritated/inflamed.

"Benzimidazoles represent the only class of truly broad-spectrum anthelmintics, however, they also show activity against fungi and mammalian cells. This raises the question as to why benzimidazoles can selectively kill helminths and yet exhibit little or no mammalian toxicity."
http://www.sciencedirect.com/science/article/pii/016947589090227U

Examples of Benzamidazole classes of anthelmintics would be Albendazole (Valbazen) and Fenbendazole (Safe-guard). Both are safely used in the removal of Helminths in chickens.

One example of a study with Albendazole:
