Ridecamp: [RC] quest? pre-loading elytes-was gastroguard

Any thoughts on whether its better to use plain table salt (NaCl only)
for pre-loading (like up to the night before dose)  I think I read on
another list a year or so ago that the potassium chloride and other
salts are more harsh on the horses mouth's if not their stomachs, and it
seems like they should not need extra of the other electrolytes until
they are exercising and using them? since they can get those things from
their normal diets.  I did this with my horses beforing hauling them
last time and they seemed more willing to eat their beet pulp with plain
salt added in, and they drank well at ridecamp. Grey especially does not
volantarily consume food that has had normal elytes mixed in, but he
didn't mind just a little plain salt added in.  I'm planning to continue
this, but would like input on when would be best to switch to normal
elytes. (night before, morning pre-dose, or not until after actually
starting exercise?)

Thanks in advance,

Teresa
