The 2007 AAEP proceedings were just released to the public.
I haven’t been through all of the papers yet, but I found this one that
is interesting. It may have been published here before. You’ll have to

Administering oral electrolyte supplements
to endurance horses is a well-accepted, yet poorly validated,
practice. In horses supplemented with
either a high-dose (HD) or low-dose (LD) of electrolytes
in a 80-km ride, we found no difference in
body-mass loss or competition time, yet estimated water
intake and rider assessment of performance
were improved with HD. However, hypernatremia and
hyperchloremia developed in some horses
receiving HD, which suggests that electrolyte supplementation
may not be completely innocuous. Authors’
