Ivermectin as a bird anthelmintic--trials with naturally infected domestic fowl.

Oksanen A, Nikander S.
Abstract

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.

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.

thank you for the advice i will surely keep that in mind.
So i opened her up today started with the esophagus. No worms. Then the gizzard all looked normal. The crop was empty but gizzard was full. Small intestine no cocci or scaring from cocci no worms but there was some inflammation. Large intestine and ceca no worms or cocci nor scaring but there was inflammation in the ceca. Opened the cranial cavity and all was well with no swelling or fluid.
So now this brings me to believe this is a bacterial infection.
So im glad i did not worm yet and will returm the Ivermectin and get the safeghard.[/IMG] notice the inflammation in the intestines and ceca.

I originally started this thread, and although it took a different turn I just thought I would give you an update on my Mareks experience. I've learned some things I didn't know before. My vet helped me send out two of my deceased chickens to a state lab. It was concluded that I have Mareks in my flock for sure. The vet was confused because I lost 3 chickens that were vaccinated. The state pathologist said the strain I have is one of the less common strains. There are different types of vaccines.. Cheap ones that only cover one type of strain, and more expensive ones,that cover more of a broad spectrum of strains. Most people chose to save money and go with the cheap vaccines. I guess that's what happened with my flock. The pathologist said that Mareks is more common in this state than people realize. A big hatchery like McMurray uses a better vaccine, so IF I ever get more I have to get chicks from there. I, will continue to lose more chickens..even vaccinated ones it seems. I have ONE chicken left from my original group that I've had since May. Considering I've had her for 8 months, and I think the disease came from where she came from.. I think she might be a survivor and she is a carrier. My vet suggested I wait until summer time and see what I have left.. If I have a few survivors I can try to raise a few McMurray chicks and see if I can add them in and if they will survive. One thing I don't understand is how long the incubation period is, but I am still learning. I've only had chickens since May, but this whole experience has been very difficult. Just thought I would share what I learned today.
