All the horses on my yard have Azoturia?!

[stacey222]

All the horses on my yard have Azoturia?! They have been out of work for 2 months now recovering but their blood still has not come back down to normal levels. They are all being fed on a low energy diet and being fed the supplement of selenium and vitamin E. They are not on rich grass or haylege. One of the horses we have had for 2 years and never tied up but we brought a new horse onto the yard and since then they have been tying up! They are all Appaloosa's with distant related bloodlines, I just don't understand why they are all tying up, please help me... all ideas welcome!!

I would assume that all the horses management is relatively similar....Have they been kept stabled? If they were turned out prior to the tying up, was their field large for the amount of horses (rich grass isn't the only problem - large quantities of grass can cause it - I speak thru personal experience!).
If they are out of work and still have high CK and AST levels, hard feed should be practically nothing bar a handful of low sugar chaff to put any supplements or oil in. Has the vet suggested biopsy for EPSM?
Are they still on box rest or having turnout now?
Sorry about all the questions, but will help us to be able to give some advice.
Just a point, when my girl tied up the first time, her levels were horrendously high and wouldn't come down to normal - vet prescribed box rest until they came down, then he spoke to an azortoria expert in newmarket and he advised turning out, even tho levels weren't right - a week after turnout, the levels returned to normal and we were riding (in walk ony for 10 mins) 2 days after that!

What ideas does your vet have about the situation ?
