Ivermectin Studies:

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.

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.

This is one that had been treated with a large amount of ivermectin. Her fecal at the time of this post was negative, but three days later the next fecal showed that she had a severe case coccidiosis and capillary  worms. By the time she was this sick she had lost almost half her body weight. She did live, but it took her owner several weeks of intensive supportive care.



I have a 3 year old peahen that lives in the aviary with a 5 year old male. The first indication that I had that anything was wrong was on Sunday, 2 days ago. She was lying in her nest box inside the coop which she never does. She is always sitting on the perch. I went in and encouraged her to get up. She popped up and ran outside to the pen just fine, but when she tried to fly up to the perch, she couldn't make it. The perch is about 4 feet high, she flapped up about halfway and came back down. She tried a couple of times and did not have the energy to get to the perch. She did peck at the scratch feed that I had scattered on the ground. Then she  went back inside and lay in the next box again.


When I checked on her later in the afternoon, she could not stand or walk without tumbling over. She doesn't want to get up, but if I get too close, she will make the effort, but falls down. She was the same yesterday. I waited down there until I could collect a fresh stool sample from each of them and took the samples to a vet. (We don't have a qualified avian vet in the area. There is one vet in a town an hour away that treats parrots and lizards, but he admits he knows nothing about poultry. He can read a fecal, though). But both samples came back clean. I didn't really expect to see any parasites, as I do a regular worming program on the birds, and they had just been wormed two weeks ago. The hen's stool yesterday was yellowish and mucus, but today it looked pretty normal, just a little softer that usual.


I don't think there is any foot or leg injury, as she was able to walk just fine 2 days ago, just seemed too weak to fly at that time. I don't know if she is eating or drinking, as I suspect it is too much effort for her to get outside to the feeder. I sprinkled some food and scratch on the floor of the pen this morning and set a dish of water in there for her.

Frankly, I was surprised to find her still alive this morning, but she was actually standing on the floor when I went in. Still flopped and fell down when she tried to walk.


If I know what medicine she needs, I can get it down her throat.


Any ideas? I hope that someone out there can help, as we have no vet to turn to here.
