Worms or Shed Intestinal Lining - Yucky Pics!!

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?
They are then larva and will grow to adults in the digestive tract. Once adults, they will reproduce and worm eggs are then excreted in feces.

Of the 4 main species of capillary worms in chickens, it looks like they reach maturity inside the chicken in 1-2 months. In an infected flock there will be eggs and adults in all stages. The levamisole directions say to repeat after 2 weeks. Chicknmania you said the advice to you was to repeat in 5 days? Subhanalah, probably anytime between 5 days and 2 weeks is fine. The different species do have slightly different maturation rates, so without knowing exactly which species is infecting the chickens it's probably moot.

The Rooster Booster may be a good choice. Since it goes in the feed surely the dosing sorts itself out; smaller chickens eat less food. I figure that feed- or water-based medication can't have a very high risk of overdose, since the exact amount the chicken is ingesting can never be accurately measured.

Yes, five days. And then a month later.

Okay, and once they are larva they are killed by the medication. So, theoretically, the reworming at 21 days is just in case any were not killed and managed to make it to adulthood/laying/reproductive age.

Hi there,
I'm from the UK and Flubenvet is even expensive here. It cost me £22.
You mix it in with the feed and give the birds no treats.
They seem to like the taste of the mixture and guzzle the pellets.
The eggs are still edible while treating.

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.

There's been a misunderstanding. The eggs in the poop are only infective AFTER 6-8 of embryonation (or more, in some species). The embryonation period is the growth of the embryo inside the egg, like the embryo of a chicken egg. If you crack open a developing chicken egg at day 15 it won't survive. If a chicken eats a 2-day old worm egg it will not get worms because the embryo inside the egg wasn't developed enough.

Here's the original source from earlier in the thread:
"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."

Dawg is right, eggs can persist in the environment for a very long time (714 days for one species, according to the source I'm attaching). After the embryonation period the eggs have an embryo capable of hatching and infecting the chicken/host. This embryo will be in stasis, that is, it won't develop any further until it is in the right conditions—a host. So yes, viable eggs will be in the environment for a long time.

Also, this is all regarding those worms with a direct life cycle, where the egg is ingested directly by the chicken. Other kinds of worms have an intermediate host. Basically the egg is ingested by an earthworm (or other host) and the larvae hatch and grow in the earthworm, this is called a first stage larvae. Once again, there is a period where the larvae need to grow some inside the earthworm before they could infect a chicken. Only second stage larvae are capable of infecting chicken. In other words, if an earthworm has only first stage capillary worm larva inside its body and the chicken eats the earthworm, the chicken will not become infected with capillary worms. In an infected flock/environment, there will be worms in all stages, and the chicken will become reinfected after treatment, thus requiring repeat treatments.

Thank you for that Tamara! I don't know why I kept reading that they are *not* infective after that time period.

 

[dawg53]

Thanks for clearing that up Tamara....and that's just the capillary worms lol!

I blame my brain for reading it "ineffective" filling in the blanks when I didn't ask it to.

I dewormed Cricket with the Levamisole on the 7th (yesterday) before I read your post about using the goat dewormer instead. She seems much improved today though (since the deworming). Standing up and eating pretty well. Drank a lot of dewormer water. So my question is...technically, this is her second dose of dewormer, though as you said, we don't know how much dewormer she got the first time. So, should I deworm her AGAIN before I let her go back out with the flock? And if so, how soon can I do this? And should I just use the Levamisole again, or something else? My plan is to deworm the whole flock again anyway, next month, on the 7th and 14th. I was going to use the Levamisole again for that, since I have it mixed, then switch to Rooster Booster or Safeguard for the next deworming the flock gets. Thanks for all the advice, everyone.

I've read about worming with the moon cycles. I think I'm going to try to deform on the full moon.

Also, I'm pretty sure you're not supposed to store constituted worming solution.? Dawg?
