My daughters horse tied-up after a 45 min. walk trot late last spring. Her levels were AST 4635 (normal 168-408), LDH 8018 (normal 140-440), CPK ?over 120,000 (normal 110-700). She didn’t need fluids as she was drinking and had low HR, good gut sounds etc. Shadow did have coffee colored urine at least once. She was walking slow for just a couple of days, after that moved and looked quite normal, however, the retest done in 2 weeks showed she was still waaay over normal. We did start handwalking a couple of miles daily. We waited another 6 weeks and she was finally back to normal. Shadow had done 2 50 mile rides 2 weeks prior and was on turnout with a couple acres of green grass, and also getting oat/wheat/barley hay, and a daily mash that had about 1 ½ cups of oats, along with a quart of beet pulp, salt, vitamins. ?Selenium was low for an endurance horse, but would have been considered acceptable for others at .187. And she was in season at the time.

Shadow has been on a selenium supplement since then, and gets even less oats when not working, more on work days. Feed the work…no work, no grain. And we always make sure the first 15-30 minutes of work is done at a walk, then slow jog.

Are they going to check the selenium level?

If it were my horse, I’d ask for no grain except on days I worked the horse. I’m sure others will chime in here.

I have a young friend at the barn whose horse (a hunter jumper) tied up on Sunday after a mild workout of 45 minutes or so out hacking in the field.  The vet came out and gave him fluids, took some blood to send off and the horse seems to have recovered.  This horse is worked lightly on a fairly regular basis (depending on the owner's homework load at school) but is at a farm that believes in really laying the grain to the horses.  I had kept my endurance horse there a few years ago and I had to fight to get to feed less and my own low starch/nsc feed.  The vet did recommend that he change to the exact feed I use and for the next week give him as little as possible just to get salt into him.  My real question (as he asked me and I have NO idea because although I have seen some horses tying up after rides I haven't had one that did so haven't done anything other than casual reading on the subject) is the creatinine level came back on his blood work as 55,000 with the normal range listed as 150-175 which is obviously severely elevated and he wanted to know if that was considered a really severe case?  I would assume so, but I would never tell someone that without knowing for sure.  He said he asked the vet and they just told him to do the feed changes and they would take blood again on monday which will be 1 week from the first blood test. 

Any insight as to the extent that level would be considered would be appreciated.
