I was getting deja-vu, thinking we’d had this thread before – OP, you started one like this a few months back right?
Tying up is a catch-all phrase. It could be from anything to extreme exercise induced muscle tremors, to RER, to PSSM2…
TBs don’t have PSSM1 - which is the disease most people think of (besides HYPP) when someone mentions tying up. They can have PSSM2, which runs the gamut for clinical symptoms.
In all of my years managing TBs, I’ve never had a TB tie up after the track, and never dealt with PSSM2 in a TB. That’s not to say it doesn’t exist, but it’s not common in my experience. I think there are a lot of external factors that contribute to tying up in racing horses and not all of it is genetic.
So to answer your question specifically – if it is genetic,no it won’t go away and anything you breed might have it too. But if it was environmental, it was likely a one time thing.
If you are concerned, you can manage her like she is clinically PSSM. High fat, low starch grain, vit E and selenium, and lots and lots of turnout.
I would take it as a good sign she has been in work for several months now with no issue. In no way does any sport home come close to reproducing the environmental and physical stressors of the track.
There are PSSM groups on FB that are worth joining, but take their input with a grain of salt. As with all things FB, there’s a lot of misinformation circling these groups and a lot of conspiracy theories (like Northern Dancer being the cause of PSSM in TBs… lol)
