I have three pastures with horses whom are exhibiting severe sheath edema. The Vet originally thought the older horse my have been injured but this is going on for almost two months. Now I have a three six month old colts that are going through the same of similar things. There are two three year old stallions in another pasture that are also having the same symptons. Any suggestions...I have just recently re-dewormed all with Strongid wormer from the Vet...I had been pouring them all with Ivomec cattle pour on as instructed by a different Vet.

Hi Cathy did they get the sheath edema After you started pouring them with Ivomec? I don't quite understand because you say you HAD been pouring them with Ivomec.
I hail from cattle country and I have never heard of using pour on Ivomec usage in horses ever. If it started after that It would be suspect in my mind.
If not can you give a little more detailed history, including feed, de- worming history, body condition score ect. that will help DrO. or others help you.

Cathy,
When Ivermectin first came out, it was in an injectable form. Many horses of both genders had reactions of edema down their stomach midline. The edema was caused by the dying off of the parasite in very large numbers, it usually cleared up in a few days, but in some cases this did not happen and some horses had bad outcomes as the toxins overwhelmed their systems.
Now of course they have Ivermectin paste wormers that horses seem to tolerate much better and I haven't seen the same reaction to those as I did to the shots, but I would be suspect that the pour on Ivomec might be way to strong for your horses on top of the strongid that they had already been treated with. I would think that since all the horses had similar reactions that it was indeed from the wormer.
Your vet needs to check these horses and make sure there is nothing more serious than a reaction going on.

Welcome Cathy,
I see you are in MO USA so not likely to be facing any toxic plants this time of year. But that stills leaves us with many possibilities. When you see something effecting 4 different horses in different locations you think: infection, toxin, or nutrition. Is there an association with the beginning use of ivermectin and this problem?
The investigation should start with a good physical exam of the horses and a thorough examination of their environment and feed. If this does not lead to a diagnosis of the cause I would recommend doing lab work on a couple of the horses.
