I think the important point here is that for
horses that are prone to tying up – by previous history or genetics –
the elimination of grain products is a key and critical part of the
solution. For horses that have never tied up – they MAY never tie
up, or they are waiting, like the original poster on this topic, for the right
set of circumstances and coincidences, to do so.
The linkage between grain (high starch)
feeds and tie ups is scienfically pretty solid. Ignore it at your own
risk. There is very little reason to feed grain to horses, with so many
other pathways to get calories and fiber into them.

Several people have mentioned having problems with Purina
Strategy.
We've fed Strategy (and beet pulp) to all of our horses since we got our first
ones back in 1998, and have never had a tying up incident. We now add
Ultium, but they all still get some Strategy, including at rides.
