Worms or Shed Intestinal Lining - Yucky Pics!!

[subhanalah]

The dosage of fenbendazole (SafeGuard, Panacur) for capillaria is 10 to 50 mg per each 2.2 lbs of weight daily for 5 days.  If I were worried, I would use the 50mg dosage which is 1/2 ml per 2.2 lb (or 25mg or 1/4 ml per lb) to treat.  Many of the studies will show differing amounts and a higher percentage of success with the higher dosage.  With chicks I might use the lower end of dosage.  Plumb's is the best vet drug handbook out there for dosages.

Okay, so with the eggs becoming ineffective after 8 days without a host, does this 5 day worming take care of the entire infestation? I guess the question is, does it kill eggs that are ingested?

The articles I have found don't give a whole lot of information. Maybe someone here would like to contact MSU about it. Here is the article from Mississippi State University about capillaria:

Capillaria (Capillary or Thread Worms)
There are several species of Capillaria that occur in poultry. Capillaria annulata andCapillaria contorta occur in the crop and esophagus. These may cause thickening and inflammation of the mucosa, and occasionally severe losses are sustained in turkeys and game birds.
In the lower intestinal tract there may be several different species but usuallyCapillaria obsignata is the most prevalent. The life cycle of this parasite is direct. The adult worms may be embedded in the lining of the intestine. The eggs are laid and passed in the droppings. Following embryonation that takes six to eight days, the eggs are infective to any other poultry that may eat them. The most severe damage occurs within two weeks of infection. The parasites frequently produce severe inflammation and sometimes cause hemorrhage. Erosion of the intestinal lining may be extensive and result in death. These parasites may become a severe problem in deep litter houses. Reduced growth, egg production and fertility may result from heavy infections.
If present in large numbers, these parasites are usually easy to find at necropsy. Eggs may be difficult to find in droppings, due to the small size and time of infection.
Since treatment for capillaria is often lacking, control is best achieved by preventive measures. Some drugs, fed at low levels, may be of value in reducing the level of infection on problem farms. Game birds should be raised on wire to remove the threat of infection. As some species of capillaria have an indirect life cycle, control measures may have to be directed toward the intermediate host. Hygromycin and meldane may be used for control. Additional vitamin A may be of value. Effective treatments that are not approved by the Food and Drug Administration are fenbendazole and leviamisole.

Yeah, I posted that up there ^^
Hahaha.
maybe @casportpony has more infirmation?

Here's some very good info from Janssen:
http://www.nutritech.co.nz/vdb/document/243

It refers to the pre-patent period for one of the species of capillary worms as up to 26 days. Also, it suggests treating for 7 days. As with everything there is lots of information and sometimes the info isn't always in agreement. As responsible poultry owners we need to do the best we can. Whether or not the 5-7 day treatment gets the eggs within the chickens may not be as important as knowing that the chickens can and will get reinfected from their environment. If you're fighting capillary worms, then according to this you'll want to do the second treatment before 26 days pass.

This link suggests it does kill the eggs (under "Uses"):

Okay, thank you so much!
So the 7 day treatment takes out the infestation, and 3 weeks later, again.
This is for a not mg/kg dosage based on weight though.

Okay, it also says you can eat the eggs...is that true?

Flubenvet can't be purchased in the US unless you order it from an England company and pay $$$. From what I have read about it, you mix the powder in the feed, and feed it for 7 days, so theoretically they take the correct dosage they need. Not as accurate as giving fenbendazole. And yes you can eat the eggs.

There's no wormer that can kill worm eggs as far as I know. As a matter of fact, they can survive in soil for years if conditions permit.
The reason for a second worming in the 10-14 day range is to kill worm larva hatched from eggs that the initial dosing missed, before they become adults to reproduce again completing their lifecycle. Capillary worms require worming sooner due to the different types of capillary worms with different lifecycles for reproducing. This is one reason I worm every three months, sometimes sooner depending on soil conditions. Warm moist/wet soil is worm soup. It has been raining here every afternoon. My new birds are currently 18 weeks old and I've wormed them 3 times starting at 8 weeks, 12 weeks, and earlier this week 3 days in a row with safeguard liquid goat wormer.

According to a previous post, the eggs are no longer infective after 6-8 days of embryonation. Can you explain exactly what that means? To me it says once deposited as fecal droppings, the (capillary worm) eggs are no longer infective that have not already been picked up by the poultry after 6-8 days?
