Worms -- Symptoms and types of worms

Postby sharron » Fri Oct 01, 2010 10:36 am

Worms are usually associated with cattle, horses, cats and dogs but chickens get them as well. Poor old Mrs Chook above doesn't look too good - probably because her cartoon owner hasn't bothered to notice the old girl has lost a lot of weight, isn't hanging around her chicken friends anymore or eating anything. As for her droppings - they aren't looking any good either. Runny and watery means only one thing..WORMS.

Symptoms of a chicken with intestinal worms are as follows:
watery runny droppings
loss of appetite
ceasing of egg laying
dehydration
going off alone
loss of balance (due to weakness from a heavy infestation)
dull comb,wattles and eyes

Not all of these symptoms occur but in the main most will be present. Sick chickens with worms if not treated can die. Birds need to be treated every three months.

Types of intestinal worms are:
Ascarids (Large Intestinal Roundworms)
One of the most common parasitic roundworms of poultry (Ascaridia galli) occurs in chickens and turkeys. Adult worms are about one and a half to three inches long and about the size of an ordinary pencil lead. Thus, they can be seen easily with the naked eye. Heavily infected birds may show droopiness, emaciation and diarrhea. The primary damage is reduced efficiency of feed utilization, but death has been observed in severe infections.

Cecal Worms
This parasite (Heterakis gallinae) is found in the ceca of chickens, turkeys and other birds. The worms are small, white and measure _ to ½ inch in length. This parasite apparently does not seriously affect the health of the bird. At least no marked symptoms or pathology can be blamed on its presence. Its main importance is that it has been incriminated as a vector of Histomonas meleagridis, the agent that causes blackhead. This protozoan parasite apparently is carried in the cecal worm egg and is transmitted from bird to bird through this egg.

Capillaria (Capillary or Thread Worms)
There are several species of Capillaria that occur in poultry. Capillaria annulata Capillaria 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 usually Capillaria 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.

Tapeworms
Tapeworms or cestodes are flattened, ribbon-shaped worms composed of numerous segments or division. Tapeworms vary in size from very small to several inches in length. The head or anterior end is much smaller than the rest of the body. Since tapeworms may be very small, careful examination often is necessary to find them. A portion of the intestine may be opened and placed in water to assist in finding the tapeworms.

Chickens also can contract Gapeworm which is a worm that lives in the lungs and trachea. This is often fatal.
Definition comes from Wikipedia:
A gapeworm (Syngamus trachea) is a parasitic nematode worm infecting the tracheas of certain birds. The resulting disease, known as gape or the gapes, occurs when the worms clog and obstruct the airway. The worms are also known as red worms or forked worms due to their red color and the permanent procreative conjunction of males and females. Gapeworm is common in young, domesticated chickens and turkeys. When the female gapeworm lays her eggs in the trachea of an infected bird, the eggs are coughed up, swallowed, then defecated. When birds consume the eggs found in the feces or an intermediate host such as earthworms, snails (Planorbarius corneus, Bithynia tentaculata, …), or slugs, they become infected with the parasite.

How to treat and prevent worms

Postby chicibo » Wed Jan 19, 2011 10:41 pm

Treatments:

Aviverm - 1 ml per 9kg's added to enough water to last 8 hours. Aviverm is an anthelmintic which provides simultaneous treatments of immature and adult stages of the three most important intestinal worms (Ascardia spp, Capillaria spp, Heterakis spp) in chickens, turkeys and other birds. This product does not treat gapeworm. Withholding times: Animals producing meat for human consumption must not be sold for slaughter within 7 days of treatment. Eggs from treated birds must not be sold for human consumption for 6 days following treatment.

Flubenol/flubevet - Mix the powder drench thoroughly into dry feed, and feed for seven consecutive days. 15g quantity of Flubenol is mixed into 25kg of feed, and will drench approximately 27 hens. (Calculated at 130g of feed per hen per day). Flubenol is a powdered wormer/drench suitable for the control of worms in poultry. Active against: Poultry: gapeworm, large roundworm, small roundworm, hairworm in crop and small intestine, gizzard worm, threadworm, and tapeworm. Flubenol (5% flubendazole Janssen) is the only anthelmintic registered in New Zealand for use in poultry that does not have an egg withholding period. It is recommended for use as a treatment/ prophylactic via the feed every 3 to 4 months, but may also be used as a continuous additive for the early part of lay.

Ivomec - Ivomec 1%. Administer 0.1ml per 4kg chicken undiluted 4 weekly for 2 doses, then 3 monthly for 2 doses, then every 6 months. Please note: This is 0.1 of a ml, NOT 1.0 ml.

Panacur - 1ml per 1kg chicken given orally. (Fenbendazole) It is effective against roundworm and giardia, this is another product that can cause feather abnormalities. Repeat dose 12-14 days. Panacur will not kill hairworms. This wormer is the main drench used by aviculturist in NZ for the past 25 years. Panacur is a very safe wormer to use, but it may cause problems if used while the bird is in molt. Egg and meat with-holding period of 10 days.

Worms -- Preventions, tip and tricks

Postby chicibo » Thu Jan 20, 2011 12:22 am

These tips and tricks may or may not work, but they're here if you want to try them! Remember, cleanliness in the coup is the best prevention!

Garlic
Cider Vinegar
Pumpkin seeds
Food grade diatomateous earth

AHE - Animal Health Elixer - http://www.stockmansfriend.co.nz/Produc ... lixer.aspx
Poultry Health Tonic and Natural Wormer - http://www.greenurbanliving.co.nz/index.php?CID=100099

If you have a worming product that needs to be given orally directly to the birds, but are not confident enough to put it directly in the beak (remember that the breathing hole is just behind the back of the tounge, and getting any fluid down it could kill your birds), Get a small peice of bread and apply the worming solution to it. Best done when the birds are hungry of course! And you may need to seperate each bird until they have eaten their peice of bread :)

Thank you raven, that is why I created this section, for ease of use and quick reference.

Most products have to be purchased through your vet, but I will make an effort to say where you can purchase products in the future.

There will be a section on lice and mites, it's just that it took me all night (5 hours) to write and edit the section on worms! It will be tonight's project, I promise!

Thanks very much for this. :D :D Now I have some ideas what I need to keep an eye out for and what to do about it! Much appreciated - by me and I';m sure Lucinda, Bonnie and Emmy Lou would be grateful too - but they are too busy pecking at stuff to get on the internet!

Hi just reading all this great info about the worm treatments.. Just a question about the aviverm and this quote
"Eggs from treated birds must not be sold for human consumption for 6 days following treatment. "
Can no one at all eat the eggs(animals or humans) and do they have to be thrown out?? Or just not sold to the public..

Thanks

The 6 days stated is the time taken for all traces of chemical residue of the wormer to clear from the body of the animal that has ingested it or anything produced by the bodyof the animal ( in this case, eggs) and will be safe to eat. There is generally a safety margin added of a day or so just to make sure. This is to ensure eggs sold to the public (who would be purchasing them with the intention of eating them) are free of contaminants that may cause any adverse reaction to the consumer.Food sold for consumption must meet NZFSA requirements regarding allowable chemical residue or other contaminants

If you choose to eat eggs laid within the withholding period of any wormer given to your chickens or give the eggs to animals to eat, you do so at your own risk.
Maybe check out Flubenol, which has no withholding period for eggs

Does anyone know where (or can get for me!) Flubenot/flubevet?

I am trying unsuccessfully to get my vet to order it in (they can't seem to track down the rep who should be able to sell it to them :roll: ) So I am desperate to get hold of some - I have 13 that I want to worm, am happy to pay someone for it, incl postage if they would send it to me :)

Re: Worms -- Symptoms and types of worms

I just thought I would add my (very limited) personal experience to this topic. I've had my 6 pullets for 5 weeks now, and have been giving them all the preventative remedies. They've had garlic, apple cider vinegar, pumpkin seeds and diatomaceous earth regularly since I got them. Today I noticed one of my chickens doing a very runny poo so I went to investigate and I could see little white worms wiggling around in it! eeeewwww! :?

So today I'm off to get some flubevet. (I hope!)

The chickens will still get all the goodies in their food because I don't believe they do any harm, and it's possible they might help to keep the worm burden low between chemical worming sessions. But I won't be relying on the natural remedies as a preventative, and certainly not as a cure.

Oh and I should also mention that this property has never had poultry on it before (as far as I know) and it's certainly not overloaded with chook poo (yet!) so I really think I had every advantage to start with. I really thought I might get away with the natural worming methods. Darn it! :roll:

By the way Sharron and chicibo, thanks for the info in this thread. It's very useful to know what worming meds are available in NZ and what the rules are. It's all very well looking at overseas info, but it's much more useful to have local info. :)
