Thought I'd start a thread about ivermectin and share all of the info I have gathered so far.
Anthelmintic efficacy of ivermectin against Syngamus trachea and Capillaria spp. in pheasant.
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.
Ivermectin as a bird anthelmintic--trials with naturally infected domestic fowl.
To evaluate the use of ivermectin as a bird anthelmintic, 29 White Leghorn hens naturally infected with Ascaridia spp., Heterakis spp. and Capillaria spp. were treated with 0.2, 2 or 6 mg/kg intramuscularly or 0.2 or 0.8 mg/kg orally. Faecal samples were collected before treatment and at autopsy, 2, 6, or 16 days after treatment, when the intestines were also examined for helminths. None of the treatments gave satisfactory anthelmintic results.
Formularies written by vets:
From another formulary:
One drop of the 1% injectable = ~0.02 ml = 0.2 mg
Here is how I calculate how much to give:
Weigh of bird in pounds, divide by 2.2, times the mg/kg that I want to give, which lately is 1 mg/kg (most vets will suggest *much* less than that), divide by 10 = the amount to give.
Example of what I give a five pound bird @ 1mg/kg:
5 / 2.2 x 1 / 10 = 0.227 ml = 11 drops
These are the amounts that a vet would probably suggest. FWIW, a vet here on BYC uses 0.3 mg/kg on their birds
Example for a five pound bird @ 0 .2mg/kg:
5 / 2.2 x .2 / 10 = 0.045 ml = 2 or 3 drops
Example for a five pound bird @ 0 .3mg/kg:
5 / 2.2 x .3 / 10 = 0.068 ml = 3 or 4 drops
Example for a five pound bird @ 0 .4mg/kg:
5 / 2.2 x .4 / 10 = 0.09 ml = 4 or 5 drops
Example for a five pound bird @ 0 .5mg/kg:
5 / 2.2 x .5 / 10 = 0.11 ml = 5 or 6 drops
As always, please check my math. And if possible, consult with a vet on how much to give.
Allegedly written by a vet:
I am assuming that the amount they use is based on an average sized laying hen, but no way to know for sure.
From left to right:
Small = 0.1 ml = 1.87 mg ivermectin
Medium = 0.25 ml = 4.675 mg ivermectin
Large = 0.5 ml = 9.35 mg ivermectin
The blob next to the grain of rice is 0.025ml (.4675 mg ivermectin)
