Ivomec is a commonly used antiparasitic agent and in some folks opinion the best antiparasitic on the market today. It is effective against a wide range of parasites such as Roundworms, Capillaria (Hairworms), Terameres, Strongyles, and a Few other less commonly seen internal partasites. Ivomec, if used properly can be effective against some external parasites such lice and mites.

Individual Dosing

A very common method of administering Ivomec is by individually dosing a pigeon. This is performed by applying drops of Ivomec directly into the pigeons mouth. The most common type of Ivomec used for this situation is cattle or swine Ivomec which is a 10% solution. This solution can be given at a dose of 1-2 drops per birds. This should be repeated in 2 weeks. Another type of Ivomec that can be used this way is baby pig Ivomec which is 0.27%. This also can be used at 1-2 drops per pigeon even though the concentration of the baby pig Ivomec is roughly 1/4 that of the cattle or swine Ivomec. The reason is this: the 0.27% solution, dose at 1 drop is actually 28 times the actual needed dose. The 10% solution if given at the rate of 112 time the actual needed dose. We are lucky, in that Ivomec is a very safe drug. Therefore, we can use either concentrated at 1-2 drops per bird, providing more than enough of the drug.

As you can see, we could even dilute the Ivomec numerous times while still providing enough drug needed for your birds. Ivomec cannot be diluted with water. It does not mix with water. This is like mixing oil and water. The best substance to dilute Ivomec with is a chemical called Propylene Gylcol. If you do decide to do this, you can dilute the 0.27% solution in half 3 times without harming its effectiveness while the 10% solution in half 5 times without causing any problems.

Propylene Glycol can be obtained by a veterinarian or a pharmacist. You must remember that diluted Ivomec must be shaken well before its use because the propylene glycol can settle while sitting on the shelf. Straight Ivomec can actually be injected but this usually never done as it is impractical. However, Ivomec diluted with Propylene must never be injected as it can cause severe reaction at the site of injection..


Other Methods of Administration of Ivomec


a common misuse of Ivomec is the addition of the swine or cattle preparations into the drinking water for worming. This is not correct as the Ivomec does not mix with the water. Thus, the drug dose ingested by the pigeon will vary greatly. Another misuse is the addition of the cattle or swine preparation of Ivomec into the bath water to treat for lice and mites. This is also not very effective for the same reason that these types of Ivomec does not mix well with water.

There is a type of Ivomec that will mix well with water. This type of Ivomec is called Eqvalen, which is for horses. This type of Ivomec is a paste but it will mix well with water. It can therefore be used in the drinking water or bath water at a rate of 7-15cc per one gallon of water.

Addition of this type of Ivomec into the drinking water for worming is quite useful in situations where it is impossible to handle all the birds. The method listed above is still the preferred method of treatment since you know for sure how much each bird has indeed took in. When you add it to the drinking water there is always the possibility that certain birds may not drink enough water for an adequate dose. Addition of Eqvalen is useful in the bath water where it can be quite effective against lice and mites.


Adverse Reaction with Ivomec

Ivomec is a very safe drug which can be used under any condition without any problems. But often times pigeons or wormed when in reality they are free from worms. Another problem is that Ivomec is not followed up with a second dose two weeks later. This is essential for proper worm control. After this program is complete treat with Aureomycin for about a week to help the birds feel better.

Ivomec is environmentally stable. This means that it can remain in our ecosystem for long periods of time. Never allow Ivomec to come into contact with ponds, rivers, or lakes. This is due to the fact that Ivomec is highly toxic to fish and crustaceans.
