Does any one use ivermectin in chickens ?

[lhamid]

Ivermectin has been used ORALLY in children over 5 years old to treat head lice. Yes, ORALLY. It is safe and effective. You can certainly eat the eggs. Only caution is certain breeds of dogs (some collies and mixes, you can Google it) may be allergic to Ivermectin so you may want to exercise caution feeding eggs to dogs right after treating. I do feed my dogs eggs from treated birds and have never had a problem (I have Lab/Golden Retriever and German Shepherd x ?). Ivermec is a very efficient wormer in chickens. I have had before and after fecals done, also seen piles of dead worms in the poop after treatment. I worm 2 X a year, spring and fall. Each treatment is 2 days, wait a week and repeat (so really I treat 4 x a year).

Here is link to article, there are plenty more out there

In mean this in the nicest way possible, but I have tried it in chickens orally, topically and by injection - it DOES_NOT_WORK for poultry lice, period. There are also many studies that show it's *not* an effective wormer in poultry and I can provide links to those if you're interested.

Poultry lice do NOT bite and suck blood like cattle lice or human lice. Poultry lice feed off skin, dander, feather sheeves/shafts. If by chance they come across a wound with blood, they will opportunistically suck it up. Otherwise ivermectin will not treat lice, but will treat mites.

Kathy, I agree, Lice are extremely hard to treat. Mites are even worse. One treatment will not control lice and mites, and you won't see instant results. A second treatment 7-10 days after the first is necessary to break the life cycle. And it is a combination of sanitation and treatment. For example, I had a rooster with horrible scaly leg mites. I found mixing a paste of sulfur powder (brimstone) with petroleum jelly and applying to legs plus 2 treatments of Ivermec was quite effective. This particular bird seems more susceptible so I have to be vigilant. I know from personal experience as well as from my avian vet that Ivermec is an effective wormer. Fecals don't lie. I am sure there are plenty of links to the contrary, as well as supporting articles. I have read many of them, both pro and con. Bottom line, Ivermectin works for me and for lots of others...

Ivermectin is ineffective as a poultry wormer due to its overuse in poultry as a miteacide. Poultry worms have built resistance to it:

I USED to use it and eprinex years ago, no more.

Fecals *do* lie, and I can point you to a thread about that, but I'll do that later. I have tried many times to treat lice with ivermectin and it has not worked, so tell me exactly how much I should give orally to a 2.2 pound chicken, how often, etc, etc. and I'll go find one with lice and try it again.

Anthelmintic efficacy of ivermectin against Syngamus trachea and Capillaria spp. in pheasant.

Lamka J1, Svobodová V, Slézková J.
Author information


Abstract

Ivermectin (IVM) was perorally administered in dosage schemes 1 x 0.8 mg/kg of body weight (b.w.), 1 x 1.6 mg/kg h.w., 3 x 0.8 mg/kg b.w., and 3 x 1.6 mg/kg b.w. to pheasants infected by Syngamus trachea and Capillaria spp. The samples of faeces were coprologically examined. The clinical state of pheasant was controlled. In all of the used therapeutical schemes the helminthostatic or partially helminthocide effect against adults of worms was reached. The clinical signs of helmithoses were reduced only. IVM in tested doses is not possible to recommend as an effective drug of pheasant syngamosis and capillariosis.

Fecal Exam Procedures

Fecal examination procedures likely to be accepted and implemented in most veterinary practices include flotation (centrifugal or passive), sedimentation, and direct examination (direct smear). Only flotation and sedimentation are concentration procedures. Direct smears have poor sensitivity because of the small amount of feces examined, but may be useful for demonstrating motile organisms. CAPC recommends that feces be routinely screened by a centrifugal flotation method, which is consistently more sensitive than simple flotation. Accuracy of centrifugal flotation techniques depends on procedural details and specimen attributes.

1. Gross examination. Specimens should be examined grossly for the presence of blood, mucus, intact worms, or tapeworm segments.
2. Sample size and preparation. Specimen size should be at least 1 gram of formed feces (1 cubic centimeter or a cube about one-half inch on a side). If feces are soft, sample size should be 2 grams. If it is slurry-like, the sample should be 4 grams. For liquid feces, a sample of 6 grams or greater might be appropriate. Inadequate sample size (e.g., fecal loop sample) may result in false-negative results. To remove large fecal debris, sieving is recommended prior to centrifugation. The sample is sieved through cheesecloth or a tea strainer after mixing with water or flotation solution. Passive flotation kits typically include a device that prevents larger particles from floating to the surface.
3. Flotation solution. Both the type and concentration of sugar or salt solutions used can affect recovery of diagnostic stages of parasites from feces. Common flotation solutes include sodium nitrate, zinc sulfate, sucrose (usually granulated sugar), magnesium sulfate, and sodium chloride. These solutes can be mixed at varying concentrations with water to achieve flotation solutions with different densities. Flotation solutions with higher densities are capable of floating heavier (denser) parasite stages. However, higher density flotation solutions also float many other fecal particles that can render preparations more difficult to examine and can collapse thin-shelled parasite stages, making them difficult to identify or causing them to float poorly. More viscous solutions, such as Sheather's sugar (sucrose) solution, are more efficient for centrifugation. Most salt solutions dry very quickly, crystallizing on slides and obscuring observation.
4. Centrifugation. Centrifugation of sieved feces may be performed in flotation solution either with a coverslip placed on top of a filled tube or with the coverslip added after the centrifuge has stopped. In the latter case, the tube is spun near-full, and then the tube is filled to form a reverse meniscus, the coverslip is added, and the tube is allowed to sit a few minutes longer. Centrifugation with the coverslip on the tube works best when a sugar flotation medium is used. Alternate methods for sampling the reverse meniscus include loops or glass rods that can be flamed between samples; however, this approach is less efficient than centrifuging with the coverslip in place.
5. Slide examination. The entire area under the coverslip should be examined. It is helpful to focus on a small air bubble to obtain the correct focal plane. The edge of the coverslip can be sealed with nail polish to prevent drying and to allow examination of the specimen under oil immersion. Sucrose preparations can be stored in high humidity in a refrigerator for hours to days without significantly altering the morphology of most common helminth eggs.

Although routine fecal examination should always include centrifugation, at times, other examination methods are needed to reach a diagnosis. For example, motile trophozoites and nematode larvae can be observed using the direct smear method. Certain nematode, trematode, and tapeworm eggs will not float in less dense flotation solutions and are better demonstrated using sedimentation. The Baermann funnel method may aid in diagnosis of a feline lungworm (Aelurostrongylus abstrusus) infection. Stained direct smears are useful for diagnosis of a protozoal infection such as giardiasis or trichomoniasis. Specimens to be examined for protozoa can first be fixed using a commercial fixative such as Proto-fix

or a fixating stain such as MIF (merthiolate-iodine-formalin). Fecal antigen detection tests are useful for diagnosis of giardiasis and cryptosporidiosis

Fecal Flotation Test

The fecal floatation test is one of the most important tests that an animal hospital does on a regular basis. This test is important because it is used to determine if your pet has intestinal worms. Most veterinarians agree that this test should be performed at least once a year, more often if there has been a history of worm problems.
A small amount (approximately 1-teaspoon) of your pets stool or bowel movement is needed to perform this test. Ideally, the sample should be collected within the past 24hrs. and put in a sealed container. If you can’t bring the specimen down to be analyzed right away then it should be kept in a cool place. This will prevent the eggs in the stool sample from hatching at which point the sample is of no value for analysis.
Once at the hospital, the technician will remove the proper quantity of feces for analysis. The sample is mixed in a special container that is filled with a solution that is more dense than eggs of the worms. Complete mixing is needed to free the eggs that are trapped within the fecal material. The container has a strainer that traps large particles and other debris from floating to the surface. After approximately 20 minutes, enough time has gone by to allow any eggs present to float to the surface. The surface is then skimmed off with a cover slip and examined under the microscope.
Each type of worm lays eggs that are characteristic for the species. Not all worms shed eggs, such as the tapeworm for example and not all worms shed eggs all the time, such as the whipworm. For this reason the overall accuracy of the fecal test is 80%. Submitting multiple samples at various times will improve the accuracy significantly. When no eggs are seen under the microscope that test is called negative, however, it would be more accurate to say that no eggs were identified.
As is the case with most tests that are performed, it is necessary to look at the results in context of the symptoms that are expressed and the physical exam findings of the whole animal. Sometimes your veterinarian will recommend worming your pet on “general principles” even though the fecal floatation test shows no eggs present. This can be a way to more positively remove any likelihood of worms being present.

Black Leaf 40 was banned because of people who can't abide by label instructions and safe storage. Ivermectin use in poultry is another example of redundant misinformation on this forum. Worthless for birds. I've used Eprinex when it first came out, and previous to that, Ivomec for Northern fowl mites. Both doses were minute as directed by a vet, but can't remember exactly, and nowhere near even a half ml. About a week later they were still on birds in both cases. In another instance less than 2 weeks later, a roundworm was found in a dropping.

Mites are blood suckers. Now, if mites don't die , then neither will lice because lice aren't blood suckers. They chew on skin and feather shafts. No residual affect is achieved with Ivermectin since it is in the bloodstream only. That is why it does not eliminate the problem quickly. The goal is to efficiently remove the threat of the parasite, and not poison the bird. With the amount of permethrin, rabon, spinosad, etc. products labeled for safe use on and around poultry, there's no reason to continue recommending products that are ineffective, or have an unknown withdrawal period. With the proven efficacy and safety of certain benzamidazole anthelmintics, there's no reason to use Ivermectin, which intestinal worms are resistant to in trial studies.
