I keep reading this term in posts and I have no idea what it means.

Used to be called Monday morning disease after hunters had their full corn/high protein foods and were not turned out or excercised. They effectively would "tie-up" the next day. The normal reason for this would be (very simplistically) a horse fed too much protein with either no work or suddenly too much. However, it can be caused by other factors which can cause the protein imbalance its not always food. Golden rule is if you suspect your horse has this, you do not move it under any circumstance (short of being somewhere really dangerous) - get a lift home if out. It causes muscle damage and there is also evidence to point out that a horse that has it once is highly prone to getting it again.
 
There are a few names for it, I think azoturia is the most common.There is probably more than one cause,and historicly it was believed to be caused by excessive protein and sudden work after a period of rest. For this reason it was also sometimes called monday morning disease.Some excellent research by (I hope I have remembered their names correctly)Doctor Stephanie Valberg and Doctor Beth Vallentine ,has now linked it to a failure to metabolise polysacharides correctly in the muscles.Their research has caused a complete reevaluation of what we believed about azoturia. I would strongly reccomend doing a search on either Pssm or Epsm.It makes for some very interesting reading.

like others have said above!! if its not treated it can be detrimental to the horses muscles. i knew of a horse at stockland lovell 2day, there was a meeting before the xc and in it explained that you should not under any circumstances put cold water on the hind quarters when they have finished and to keep them covered to stop tying up and put cold water on the shoulders and neck to cool the horse down. so when this horse came back, they chucked buckets loads of water on its hind quarters and it tyed up hurendously!!

It is not a protein imbalance, starch is the problem and too much of it. in short it causes a build up of lactose which causes the muscles to 'cramp'. It can happen when a fit horse is suddenly stabled and fed starchy cereals. I do agree that you should not move the horse, this can cause permanent muscle damage. Once a horse has had an episode they will always be prone to it and should be fed a low starch diet of fibre and oil.
